4 Common Air Conditioning Issues: Troubleshooting Guide

Air conditioners are one of the most integral parts of a home once the summer hits, which makes having an air conditioning troubleshooting guide so important. An AC unit can last for a number of years if it’s properly taken care of, but sometimes unexpected issues arise that may be difficult to diagnose.

Spotting an issue and being able to take action to fix it is vital to preserving the lifespan of your AC. It also saves you time, energy and money, while reducing the chances of needing to replace the unit.

Here are some common air conditioner issues and suggested solutions to help keep you cool all summer long.

Issue 1: No cool air

Solution: Generally, this is due to a lack of airflow. Make sure you have a clean filter in the unit to allow adequate cool air to blow through. If the filter has been replaced and you’re still having issues, contact Dows ClimateCare to get further help sourcing the issue.

Issue 2: Strange noises

Solution: Different noises can mean a variety of things. A banging noise can indicate a loose or broken part or that a part is out of balance. A clicking noise can be a sign of electrical issues. Any strange noise, such as humming, buzzing or rattling, should be checked out by a certified technician.

Issue 3: Leaks

Solution: This problem should be dealt with sooner than later by a trained technician. Leaks can lead to bigger, more costly problems and can be harmful to you, your family and the environment. Try to prevent the spread of leaks as best you can by laying down towels in the affected area until your technician arrives.

Issue 4: Automatic mode not working

Solution: Start by looking at your thermostat, as it may need new batteries. Old batteries can sometimes cause erratic operation. If that’s not the problem, it may be a relay or control board malfunction or an electrical issue. Have it inspected by a technician.

Top 10 Ways to Cool Your Home this Summer (Without Sky-High Bills)

Mon, 29 Jun 2026 19:56:43 GMT

1. Dial In Your Thermostat

Weather in Kingston, Belleville, Trenton, Napanee, and the surrounding areas is trending hotter while electricity and gas prices climb, making it tough to keep your house cool without blowing the budget. The good news? We have ten energy-efficient ways to cool your home in the summer heat, either for free, at a low cost or as a one-time investment upgrade. You’ll stay comfortable, trim your carbon footprint, and lower electric bills all season long.

Whenever you’re ready for professional help, the friendly experts at Dows ClimateCare can fine-tune, repair, or upgrade your system for substantial savings.

Using your thermostat strategically can help improve comfort and reduce energy costs. When you're away from home, consider raising the temperature slightly so your system isn't working harder than necessary. A smart or programmable thermostat can make these adjustments automatically and even take advantage of local time-of-use electricity rates by cooling during lower-cost periods. It's a simple way to improve efficiency and help lower your energy bills.

2. Maximize Fan Power

Ceiling fans set counter-clockwise create a breeze that feels roughly 4 °C cooler on your skin, letting you nudge the thermostat up without sacrificing comfort. Don’t have central AC? Don’t worry! At night, place a box fan in a window on one side of the house and open another window opposite to pull in cool air for free.

3. Block Solar Heat Gain

Close blinds or use blackout curtains, especially in south- and west-facing windows, between 10 a.m. and 4 p.m. when the sun is at its highest. If heat is still building up indoors, add reflective window film or exterior shutters. Both cut out radiant heat before it ever enters your living space.

4. Seal & Insulate

Weather-strip doors, caulk window gaps, and make sure attic insulation meets today’s R-value* standards. Fewer leaks mean less hot air sneaking in and less cool air leaking out, easing the load on your AC or heat pump.

*R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value, the better the thermal performance.

5. Service & Upgrade Cooling Equipment

A yearly tune-up keeps filters clean, coils shining, refrigerant levels high, and airflow strong; small investments that recoup big savings in efficiency.

If you have an older AC, consider upgrading to something more powerful and efficient. Using equipment with multiple stages of cooling allows for more consistent comfort than single-stage equipment that only has On and Off modes. If you don’t have a centrally ducted home, there’s no issue. Ductless heat pumps also act as air conditioners and provide the same benefits as a central AC on a zone-by-zone basis.

6. Reduce Indoor Heat Sources

Large ovens, incandescent bulbs, and long hot showers add a surprising amount of heat. Summer is the perfect time to fire up the grill. Hot dogs, hamburgers, steaks and kebabs on the BBQ are essential ingredients of summer, and keep the heat from cooking outside, where it belongs!

For indoor prep, make shorter, cooler showers part of your daily routine, lean on microwaves, air fryers, toaster ovens, and rice cookers, and swap every remaining incandescent for cool-running LEDs.

7. Control Humidity

High humidity makes 25 °C feel like 30 °C. Run bathroom and range-hood fans that vent outdoors, switch your heat pump or AC to “dry” mode on sticky days, or add a stand-alone dehumidifier to basements. Drier air lets you dial the thermostat higher and still feel refreshed.

8. Harness Night & Passive Cooling

When evening temperatures dip below indoor temps, open upper and lower windows to create a chimney effect that flushes out warm air. In drier climates, hanging a damp sheet in front of an open window speeds evaporation for a few extra degrees of free cooling.

9. Shade the Exterior

Plant trees on the south, east, and west sides of your home to block the high summer sun yet let winter light through. Pergolas, awnings, or exterior solar shades over southern windows can slash solar heat gain by up to 65%.

10. Track & Tweak Energy Habits

An inexpensive real-time electricity monitor shows exactly when and where power spikes. You’ll spot surprises, like a computer that never sleeps, and fix them fast.

For inexpensive maintenance you can do, set monthly reminders to replace or wash HVAC filters. If the filter becomes very clogged, it can even cause your system to stop working by freezing the evaporator coil. Proper airflow is essential!

Have You Thought About a Heat Pump? Why Heat Pumps Save Money

Wed, 27 May 2026 19:48:21 GMT

Do heat pumps save money? Most people don’t know how heat pumps work, or much about them at all. They are a great alternative to gas or electric furnaces and an alternative to an air conditioner. A heat pump is a single appliance that can keep your house at the right temperature, efficiently.

How Does a Heat Pump Work?

In a way, a heat pump is like the opposite of a fridge. It uses refrigerant to absorb, but instead of removing that heat from a space, like a fridge does, a heat pump moves the heat and releases it. A heat pump finds heat in the ground or in the air—even when it’s cold outside and moves that heat into your home.

Are heat pumps worth it in Canada? After all, it seems like our extreme cold temperatures would mean the heat pump has no heat to move. According to Natural Resources Canada, when it is -18°C outside, the air contains 85 percent of the heat it contained at 21°C. While the change in temperature makes a big difference to us, a heat pump still has plenty of heat to work with.

How Does a Heat Pump Work in Summer?

In the summer, the heat pump can run in reverse. It finds heat inside your home, absorbs it, and releases it outside or into the ground. It doesn’t matter how hot it is outside, because the heat pump is only concerned with moving heat outside. It doesn’t generate cold air or need any cold air to work. The result is simply less heat in your home, which keeps your home’s temperature down.

Do Heat Pumps Save Money?

Most heat pumps are electrically powered, so they will cost you some money on your utility bill. However, heat pumps are much more efficient than gas fired furnaces and even most air conditioners. It’s a lot easier to simply move the heat that exists, rather than trying to burn fuel to make hot or cold air, as a furnace or air conditioner does.

Plus, if you have a heat pump, especially a ground-fed heat pump, you may be able to get through your winters and summers without using your furnace or air conditioner at all. That saves you the expense of buying and maintaining two appliances. Instead, you can use your heat pump year-round.

Some people do choose to use their heat pump with a furnace. If so, you can get more consistent winter temperatures in your home and still replace your air conditioner outright with the heat pump, which can save you money overall.

Discover Heat Pumps from Dows ClimateCare

If you have questions about heat pumps or are ready to get one installed in your home, reach out to us at Dows ClimateCare. We can tell you if a heat pump will save you money, or if you’re better off with a traditional HVAC system.

The 5 Signs It’s Time to Upgrade Your AC Unit According to Experts

Tue, 28 Apr 2026 17:51:00 GMT

1. Inadequate Cooling Performance

As temperatures rise, the reliability of your air conditioning (AC) unit is crucial for home comfort. However, understanding when to repair or replace your cooling system can be challenging since you don’t want to discard a potentially functional unit, but you also don’t want to spend more than needed on costly repairs.

This guide will explore the signs indicating it’s time to consider a complete AC upgrade.

If your AC unit struggles to maintain a comfortable temperature or fails to cool some areas of your home, it might be a sign of its diminishing efficiency. Older units often cannot keep up with the demands of modern living, leading to uneven cooling and discomfort during hot days.

2. Frequent Repairs and Breakdowns

Recurring issues and frequent need for repairs can be both frustrating and costly. If your AC unit demands constant attention and repairs, investing in a new, more reliable system might be more economical in the long run.

3. Age of the Unit: Over 15 Years

The age of your AC unit is a significant factor. Most systems have a lifespan of around 15 years. If your unit is nearing or has surpassed this age, its efficiency is likely compromised. Upgrading to a newer model not only enhances performance but also offers advanced features and improved energy efficiency.

4. Rising Energy Bills

A noticeable increase in your energy bills, despite no significant change in usage patterns, can indicate that your AC unit is losing its efficiency. Newer, energy-efficient models can help reduce your energy consumption and costs.

5. R-22 Refrigerant Use

If your current AC unit uses R-22 refrigerant (Freon), which is being phased out due to its environmental impact, replacement becomes essential. New AC systems use more environmentally friendly refrigerants, aligning with current regulations and sustainability efforts.

Get The Complete Diagnosis from an HVAC Expert

Deciding whether to repair or replace your AC unit is an important decision. Speaking with an HVAC expert from Dows ClimateCare can help you understand the most efficient and cost-effective options for your home.

Benefits of Air Source Heat Pumps: Efficiency, Cost Savings, Improved Comfort & More

Fri, 20 Feb 2026 16:21:50 GMT

What are air source heat pumps, and how do they work?

Are you looking for a smart way to heat and cool your home? Air source heat pumps (ASHPs) might be just what you need. Not only do they offer a more sustainable way to manage your home’s temperature, but they also come with a host of benefits that could save you money and improve your comfort. Let’s dive in and see how these systems work and what makes them a great choice fo homeowners in Trenton, Kingston, Belleville, Napanee and the surrounding areas.

Air source heat pumps are clever devices that move heat from outside to inside your home to warm it up and can reverse the process to cool your home in the summer. They’re incredibly efficient because they transfer heat rather than generate it, using little electricity and zero fossil fuels. This, in turn, dramatically reduces your carbon footprint.

Imagine getting efficient heating and cooling all year round, all from the same system. That’s the beauty of ASHPs.

What is a hybrid heating system, and can it save me money?

A hybrid heating system combines an ASHP with your existing heating system, usually a furnace , to provide a more efficient heating solution in the coldest weather. It uses the ASHP as the primary heat source and only switches to the furnace on extremely cold days when the ASHP might not be sufficient. This can lead to significant savings on your energy bills, making hybrid systems an attractive option for many Canadian households.

What are the long-term benefits of installing an ASHP?

Installing an ASHP in your home can offer several long-term benefits, including lower energy bills due to its efficiency, reduced carbon emissions for a greener lifestyle, and year-round comfort with consistent heating and cooling (i.e. you only need one device for summer, winter and everything in between). In addition, ASHPs have a long lifespan and can provide reliable performance for years, making them a smart investment for the future.

How do air source heat pumps compare to other renewable heating solutions?

When compared to other renewable heating solutions, ASHPs stand out for their versatility, efficiency, and lower installation costs. They are simpler and less expensive to install than geothermal systems (also known as Ground Source Heat Pumps or GSHPs), and don’t require the extensive area needed to support the GSHP’s loop, or the space that solar panels demand. Plus, with advancements in compressor technology, ASHPs are becoming increasingly efficient and effective – even in colder climates – making them a viable option across Ontario.

Are cold climate ASHPs effective on their own in the winter?

Yes, modern cold climate ASHPs are designed to work efficiently even in freezing temperatures. They have improved components and technologies that allow them to extract heat from the air even when it’s extremely cold outside, providing reliable heating throughout the winter months.

If you’re regularly looking at below -20°C on your weather app though, it’s best to “hire backup”—be it a furnace, space heaters or a gas fireplace .

What are the economic incentives for installing air source heat pumps in Canada?

Canada has historically offered various economic incentives for homeowners looking to install ASHPs, such as rebates , grants, and tax credits. Programs like the Canada Greener Homes Grant have been popular among homeowners to offset the initial cost of purchasing and installing an ASHP. Although this program has ended, you can still qualify for the Canada Greener Homes Loan, which can help cover the initial cost of purchasing and installing an ASHP.

Government (Federal and Provincial) programs are continuously evolving, so it is best to work with a local HVAC contractor who can take you through the best options for your home and family.

At the 2025 Heat Pump Symposium, ClimateCare emphasized the importance of getting design and installation right the first time- read more about what he shared at the event .

Learn more about your options when it comes to offsetting the cost of a heat pump by contacting Dows ClimateCare !

How much does a heat pump cost in Ontario?

The cost of a heat pump in Ontario can vary depending on the type, size, and specific installation requirements of your home. Generally, air source heat pump installation costs range from $3,000 to $15,000, influenced by system type, home size, and specifics. Ductless systems typically start around $3,000, while ducted systems may vary depending on whether you have existing HVAC ducts and how large your space is.

When does the Canada Greener Homes grant end?

The Canada Greener Homes Grant program is no longer accepting new applications as of February 5, 2024. This decision comes due to the program’s higher than expected demand, with application amounts exceeding initial projections.

Although the Canada Greener Homes Grant has ended, the Canadian Government is starting the next phase of the Canada Greener Homes Initiative, which can see homeowners qualifying for up to a $40,000 loan to help with retrofits.

Will the government of Canada offer new heat pump rebates?

The Government of Canada is working on the next phase of the Canada Greener Homes Initiative , aiming to help more Canadians save on their energy bills. This includes maintaining the Greener Homes Loan, offering up to $40,000 to help homeowners make energy-efficient upgrades, as well as the Oil to Heat Pump Affordability Grant (OHPA) , designed to assist Canadians in transitioning from oil heating systems to more efficient heat pump solutions.

Are heat pumps eligible for the Canada Greener Homes Loan?

Yes, many heat pumps are eligible for the Canada Greener Homes Loan, which offers financial support to Canadian homeowners making energy-efficient upgrades to their homes. This loan can cover a portion of the cost of purchasing and installing an ASHP, making it easier and more affordable to improve your home’s energy efficiency.

It is important to note that there are specific eligibility criteria that must be met. A list of approved equipment that meets or exceeds these criteria exists and is updated several times a year. It is best to work with your local HVAC contractor to ensure the heat pump you are considering is eligible for any rebate or loan programs you’re hoping to take advantage of.

Are there any heat pump rebates in Ontario?

Hydro One offers various financial assistance programs for income-eligible participants in Ontario. These initiatives can include upgrades to help reduce energy use and costs. We also recommend checking for rebates with your municipality, as many cities across the province offer region-specific programs.

Other programs and initiatives offered in Ontario are Enbridge’s Clean Home Heating Initiative , Oil to Heat Pump Affordability (OHPA) Program , and the IESO & EAP Electric Heat Programs .

Are air source heat pumps more cost-effective compared to traditional heating systems?

Yes, air-source heat pumps are generally more cost-effective than traditional heating systems over the long term. Their high efficiency means they use less energy to heat and cool your home, leading to lower utility bills. Plus, with incentives and rebates available, the initial investment can be more manageable than you might think.

4 Reasons to Consider a Hybrid Heating System For Your Home Comfort

Wed, 21 Jan 2026 22:06:11 GMT

As we step into 2026, the conversation around home heating is evolving, with a significant focus on efficiency and sustainability. A standout solution that has garnered attention is the hybrid heating system. But what exactly is it, and more importantly, can it save you money? Let’s dive in.

Understanding Hybrid Heating Systems

A hybrid heating system merges the efficiency of an Air Source Heat Pump (ASHP) with the reliability of your traditional furnace. The system primarily relies on the ASHP for heating, switching to the furnace on those bitterly cold days when the ASHP might not suffice. This smart switching ensures optimal energy use, adapting to varying weather conditions to maintain comfort while conserving energy.

The Promise of Savings

One of the most compelling reasons to consider a hybrid system is the potential for significant savings on energy bills. By optimizing the use of the heat pump during milder conditions and reserving the furnace for extreme cold, hybrid systems can reduce overall energy consumption. This efficiency translates into lower monthly costs, with some estimates suggesting savings of up to 50% annually on heating.

Comfort and Consistency

Beyond savings, comfort is a key benefit. Hybrid systems provide consistent heating, eliminating the fluctuations in temperature that can occur with single-source systems. Whether it’s a mild fall day or the deep freeze of a Canadian winter, your home remains a cozy retreat.

Environmental Impact

Choosing a hybrid system aligns with a growing desire for more sustainable living. By reducing dependency on fossil fuels and decreasing greenhouse gas emissions, hybrid heating systems offer a more eco-friendly alternative to traditional heating methods.

Rebates and Incentives

To make the switch even more appealing, many rebate and incentive programs may be available for homeowners in Kingston, Belleville, Trenton and the surrounding areas. You could be eligible for rebates, grants, or financing options that help offset the cost of upgrading your heating system. Get in touch with our team to learn what incentives may be available to you.

Is a Hybrid System Right for You?

Deciding on a hybrid heating system involves considering your specific needs, the climate in your area, and the potential long-term savings. For many households, especially those in regions like ours with varied temperatures, a hybrid system offers an attractive blend of efficiency, comfort, and environmental responsibility.

Seasonal Safety Tips: 3 Common Gas Fireplace Problems You Can Prevent with Annual Service

Thu, 18 Dec 2025 15:32:32 GMT

When winter settles in across Ontario, there’s nothing like the steady warmth of a gas fireplace to keep you comfortable. But if you want the most out of this appliance, you’ll need to commit to seasonal maintenance. While gas fireplaces burn cleaner and require far less upkeep than wood-burning units, they’re still mechanical systems that require regular servicing to stay safe and reliable.

Knowing what to watch for also helps protect your fireplace and your home. Here are three common problems with gas fireplaces and how a Dows ClimateCare WeCare Maintenance Plan can help.

#1 – Buildup and Soot

Even in a clean-burning gas fireplace , dust, dirt, pet hair, and even insects can accumulate over time and begin to clog the burner ports and orifices. When that happens, the fireplace can’t burn fuel properly, leading to poor combustion and visible soot.

Unlike wood-burning fireplaces (where soot is expected), any soot on the glass or inside the firebox of a gas unit is a warning sign. It can indicate deteriorating ceramic logs, blocked burner passages, or incomplete combustion, all of which affect performance and safety. If you notice the glass darkening or a buildup forming, it’s time to schedule service right away.

#2 – Wear and tear on components

Gas fireplaces may look simple from the outside, but inside, they rely on mechanical parts that experience wear every time the unit cycles on and off. Over a season, that wear can affect how safely and reliably the fireplace operates.

Examples of critical parts that need inspection and cleaning include:

Valves and gas connections (to avoid potential leaks)
Thermocouple and thermopile
Ignition and pilot assembly
Fan and controls

When these parts begin to fail or fall out of adjustment, the result can be anything from hard starts and weak flames to poor performance, or, in rare cases, safety risks such as fire or gas ignition issues. A WeCare Maintenance Plan catches small problems early, long before they lead to costly repairs while ensuring the safety of you and your loved ones.

#3 – Venting and chimney issues

Blocked or restricted venting is another common issue, often caused by animals and nests (like birds, squirrels, raccoons, or bats) finding their way into chimney flues or exterior vents. When nest materials build up, or an animal becomes trapped, odours and ventilation problems quickly follow.

High-efficiency gas fireplaces can also contribute to venting concerns, as they pull more heat into the home and leave cooler flues behind. That cooler air increases condensation, and when moisture mixes with combustion gases, it can create a corrosive environment that damages liners, mortar, and surrounding brickwork. Staying ahead of venting issues with annual inspections helps protect both your fireplace and the structure around it.

What’s included in a Gas Fireplace WeCare Maintenance Plan

A professional gas fireplace maintenance visit covers far more than a quick cleaning — it’s a full 22 point inspection to ensure every part of the system is operating safely and efficiently. Core service tasks include:

Complete inspection of all system components
Check and adjust the pilot light
Clean and, if needed, reposition or replace ceramic logs
Inspect thermopile, thermocouple, fan, venting, and thermostat
Confirm safe gas pressures and leak-free connections

Because many issues start small and out of sight, a trained technician can catch problems a homeowner wouldn’t typically notice.

When to Schedule Gas Fireplace Maintenance

Gas fireplaces should be serviced once per year, ideally before the heating season begins, to ensure they’re ready for steady use. You should also book a service any time you notice these warning signs:

Soot on the glass or unusual smells
A fireplace that won’t start or produces irregular flames
Recent renovations or work that may have affected the venting system

Preparing Your Home for Winter: Essential Heating and Indoor Air Quality Tips

Thu, 18 Dec 2025 15:20:02 GMT

Across Ontario, the sun is rising a little later and setting a little earlier. Fall weather will fade and be replaced by the softer winter season. It’s the perfect time to be proactive by ensuring your home’s heating system is ready to go for the chillier weather ahead.

As surely as the first snow prompts a flood of calls to local mechanics and tire shops, the first frosty evening signals the heating season for most of us…and a very, very busy few days at heating servicers across the province. The phones don’t stop ringing with requests for urgent repairs and tune-up appointments alike. To avoid the delays caused by this seasonal spike, book your annual tune-up now with a Dows ClimateCare professional! If you’re not maintaining your mechanical appliances yearly, at least turn on your furnace or heat pump (in heating mode) early, just briefly to test it. If there’s any issue, be sure to call right away and make sure you’re at the front of the line!

WHY SHOULD I MAINTAIN MY FURNACE OR HEAT PUMP?

Heating systems are mechanical appliances. They’ve got motors, belts, bearings, and electronic components – just like your car. And like today’s vehicles, many still use gas, while some are fully electric. Yet, despite these similarities, many people don’t treat them equally. It’s an irony the heating and cooling industry has been working to combat for decades. If most people treated their cars the way they neglect their home’s mechanical appliances, the tow truck industry would be a lot busier! And while everyone seems to know to keep fuel in their car, change its oil, and seek advice when something doesn’t sound or feel right – many of these same people won’t call their heating contractor until the furnace won’t start and the house is cooling down quickly. To avoid getting stuck, have a licensed professional maintain your home comfort systems every year.

WHO SHOULD DO THE MAINTENANCE?

If you’re using gas, they’ll need a gas licence from the TSSA. If your home is heated with a heat pump, make sure your contractor has a 313D Residential Air Conditioning Systems Mechanics licence and is qualified to work on this type of equipment. If you’d like to ensure your systems run at peak e ciency, last longer, and are less likely to fail your family by breaking down, yearly maintenance is key. Whether your system is tuned-up before the big season, or just after it’s over, the benefits are the same. There’s no need to call when it’s busy! And you don’t need to pay full price for a professional to visit, either.

With Dows ClimateCare’s WeCARE maintenance plans , you can do this and save money – not to mention reap other benefits like discounts, front of the line emergency service, and more.

ESSENTIAL COMPONENTS TO CHECK FOR WINTER INDOOR AIR QUALITY

We also know that with the cooler weather arriving, and the children in schools and daycares means germs will spread at peak rates. Many of us don’t prepare for cold and flu season proactively; we hope we don’t get afflicted, but if our throat gets scratchy or our sinuses feel pressured, we reach for a warm drink, a little extra rest, and often a quick trip to the pharmacy. While a healthy diet will always be critical to your health, you might be surprised to learn that your home comfort system plays a big role in it, too!

Most of the air we breathe is indoor air. The EPA has suggested that indoor air can be 25 to 100X denser in pollution than outdoor air. We also know that poor indoor air quality can lead to a bevy of health problems, including chronic respiratory diseases. It can also be less worrisome, but it still has unwanted symptoms like headaches, dry eyes, nasal congestion, nausea, and fatigue. It’s a key way to spread germs like the cold and flu viruses. Luckily, your home comfort system can help protect you! Here are a few ways to stay ahead of the curve of seasonal sickness this year.

1. YOUR FURNACE FILTER

Whether it’s heating or cooling season, and you use a furnace or heat pump with an air handler, the filter placed beside that unit is your first line of defence against airborne particles. In many cases, it’s also your only defence, so it’s critical that it’s working well. Several different quality filters are available, each with a Minimum Effciency Rating Value or MERV rating. The higher the value, the better the filter. Dows ClimateCare recommends using a MERV 11 or higher rating filter, which should filter out about 95% of particulates like lint, pollen, dust mites, mould spores, pet dander and smoke. Moving to a MERV 13 rated filter filtration should increase closer to 98%. It’s worth noting, too, that not all filters are built equally. The “1-inch” thick filters you buy from the hardware store aren’t optimal and should be inspected at least monthly, more frequently if you’re doing renovations around the home or have pets that shed hair.

PRO TIP: Ask Dows ClimateCare about media cabinets that support 5” filters that only need to be changed once or twice, a year and can often easily be retrofitted into your existing furnace or air handler’s ductwork.

2. AIR EXCHANGER

If your home was constructed in the last 20-30 years, there’s a very good chance that it has an air exchanger system. The most common is a Heat Recovery Ventilator or HRV. This unit has a motor and a small, usually round, duct system that lives in your mechanical room. It brings fresh, outdoor air into your system, and during the winter, it works to retain the heat from the stale indoor air it expels and exchanges. If you’d like to retain humidity too, you should look at a similar system known as an Energy Recovery Ventilator or ERV. If you have an older home that doesn’t include such a system, worry not – a Dows ClimateCare professional can do a retrofit installation with ease.

PRO TIP: Have your HRV or ERV system serviced and cleaned periodically. Particularly because it deals with humid air, annual cleaning and maintenance will ensure that your ventilation system is running smoothly and effciently.

3. HUMIDIFIER

Modern homes have very tight building envelopes; they’re well-sealed and avoid a lot of the ineffciency and discomfort associated with older, drafty buildings. One challenge this creates is the lack of consistency in humidity between the seasons. When you’re heating in the winter, and bringing in cold, dry air from the outdoors through the HRV, your home’s humidity can dip. Most experts agree that about 30-40% relative humidity is ideal for indoor environments during the winter months. If you’re seeing numbers below this range in your home, or see symptoms like dry, itchy skin, or nose bleeds in extreme cases, be sure to ask your heating professional about installing a whole-home humidifier. It’s probably a lot less expensive than you’d expect and can have a huge impact on your well-being and health if you’re breathing overly dry air!

PRO TIP: A central humidifier also has a “filter” or pad, like your furnace, that needs to be changed. Generally, once a year is fine; be sure to set a note in your calendar as a reminder to change it.

4. UV-C

Whether you’ve got a basic furnace filter or a full HEPA system, these systems are designed to remove particulates from the air you breathe. For people who want to go a step further, we recommend UV-C lights. UV-C effectively controls mould and bacteria growth on your air conditioner’s indoor coil – a surface that normally has the two things mould likes most – darkness and moisture. Surface treatment with UV-C light is a proven way to keep your air conditioner’s indoor coil clean.

PRO TIP: Keep your paint cans and other chemicals away from your mechanical room! Far too often we see these items kept right beside the furnace. Paints and other chemicals contain volatile organic compounds. These VOCs can be dangerous to your health. Please store them somewhere else that’s not so close to the lungs of your home’s air circulation system!

PROTECT YOUR COMFORT AND HEALTH THIS WINTER

Getting your home ready for winter is simple with the right proactive steps. From checking your furnace to improving indoor air quality with filters, humidifiers, and UV-C technology, a few small actions now can lead to big benefits in comfort and health when colder weather arrives.

Why Heat Pumps Are the Smart Choice for Canadian Homes

Mon, 24 Nov 2025 19:59:54 GMT

Heat Pumps Explained

Over the last several years in particular, a lot of Canadians have been exposed to the term “heat pump” – often for the first time. This is largely thanks to their rising popularity that’s been fueled by government-funded rebate programs. So, what is this “new” technology, and why should anyone pay attention to it? More to the point: why are we talking about heat pumps in the middle of the summer?!

The first thing to understand is that nearly all heat pumps are dual purpose; they both heat and cool your home. It’s a bit of a misnomer in English, but if you were to directly translate the term from French, a thermal pump is a better description. And here’s an idea that’s really going to blow your mind; if you have a central air conditioner, you already have a heat pump!

An air conditioner is really just a heat pump in a “cooling only” configuration. It works very much the same way a heat pump does, except that it doesn’t have a reversing valve to switch from cooling to heating mode. This might be one of the largest marketing failures of the heat pump industry. Canadian building and HVAC expert Gord Cooke actually calls them “dual purpose air conditioners”.

Why Heat Pumps Are Worth It

So, now that you know you’ve been trusting a heat pump to cool and dehumidify your home for decades, you shouldn’t be apprehensive about trusting that same process to heat your home in the winter. It also comes with some great bonuses:

1. It’s more efficient

Because heat pumps don’t generate heat – they simply transfer it from outdoors to indoors – they use much less power than direct heating appliances like furnaces . This can save you big money on your heating bill!

2. It’s greener

Heat pumps use clean electricity, and don’t burn any fossil fuels, so there’s no carbon footprint associated with using them. They help us commit to a greener, more environmentally-friendly way of heating our homes.

3. It’s tried and true

There’s a lot of misinformation out there that heat pumps are new. In fact, they first trace back to thermal transfer devices devised in the mid 1850s. The recent surge in popularity can be attributed to advances in compressor technology that’s driven increases in efficiency.

4. But it’s too cold here for a heat pump

This common argument just doesn’t make sense. Nearly all heat pumps sold and installed in Ontario are cold climate rated, capable of extracting and transferring heat from the coldest outdoor conditions.

5. But I like my gas furnace

And you’re welcome to keep it as a backup for days when you want the heat to be near-instant. Pairing a heat pump with a gas furnace, known as a hybrid system, is one of the most common installation configurations! Since the entire system is controlled by the thermostat, you as the homeowner get to choose how you use the heat pump. You can use it as an air conditioner for cooling only, let it do the majority of the heating to favour efficiency, or have the furnace kick in earlier to ensure the temperature you want remains constant. You’re in complete control of the system!

6. It’s quieter

Heat pumps also often have quieter operation in cooling mode than most air conditioners, usually around 55 decibels. This means less noise near your outdoor living spaces, and even quieter operation when inside your home.

7. It fits tight spaces

Worried about space? Side discharge heat pumps have smaller footprints than traditional air conditioners, which makes them a great fit for tight spaces – especially if that’s in a close-fitting space between neighbours.

Life Expectancy Of Water Heaters: Tankless On-Demand vs Hot Water Tanks

Thu, 09 Oct 2025 19:01:33 GMT

If you’re planning an upgrade (or trying to avoid a surprise leak), the life expectancy of water heaters is something you’ll want to understand. In Canada, conventional tank-style water heaters generally last about a decade (sometimes longer with great water quality and maintenance), while modern tankless models can reach two decades or more with proper care.

This post explains how and why lifespans differ, the wear-and-tear patterns to watch, what maintenance really adds to service life, how insurance and warranties factor in, and how to choose between tank and tankless for your household’s needs.

What Appliance “Life Expectancy” Really Means

A manufacturer’s warranty is not the same as expected service life. Warranties (often 6–12 years for tanks; longer heat-exchanger warranties for many tankless models) indicate how long the maker will stand behind key components. It’s not a promise of f ailure at year 13.

Real lifespan depends on usage, water quality, installation quality, and maintenance. Dows ClimateCare sees a typical practical range of ~10–15 years for tanks and ~20 years for tankless, in line with Canadian utility guidance.

Typical Canadian Water Heater Lifespans

Tank (gas or electric): about 10–15 years in Canadian conditions

Tankless (gas): about 20 years on average with proper maintenance.

Heat Pump Water Heater (hybrid tank): efficiency standout; lifespan often similar to electric tanks, with maintenance needs for filters/condensate and adequate space/air volume.

Why Hot Water Tanks And Tankless Heaters Wear Differently

Tank Water Heaters: Corrosion And Sediment Are The Enemies

Steel tanks are lined and protected by a sacrificial anode rod . Over time, that rod depletes. Once it’s spent, corrosion accelerates inside the tank. Add sediment buildup from hard water, and you get hotter spots, noise (popping/rumbling), and stress on the glass lining, which eventually leads to leaks. Proactive anode checks and periodic tank flushing slow this arc.

Many Canadian utilities note a practical replacement window near the 10–15 year mark because corrosion risk rises sharply after that point.

Tankless Water Heaters: Watch for Scaling And Flow

With no storage tank to rust through, the main wear item is the heat exchanger. Hard water scale insulates heat transfer surfaces, forces higher burner or element output, and can trigger error codes. Annual (sometimes biannual) descaling in hard-water areas keeps efficiency and extends life; Canadian manufacturers explicitly recommend professional descaling.

Well-maintained tankless units commonly reach ~20 years in Canadian guides, but neglected scale in hard-water regions will cut that short.

Policy Context: Insurance, Codes, And Risk

Even if a tank still “heats,” many Canadian insurers tighten coverage or require replacement at around 10 years because of the water-damage risk if a tank fails. It’s common to see exclusions , higher deductibles, or coverage refusals for older tanks, so check your policy.

Gas-fired appliances also fall under provincial safety regimes. Bodies like TSSA in Ontario emphasize regular servicing and the importance of pressure relief valves being installed and functional.

Factors That Shorten Or Extend Service Life

Water Quality (Hardness): Hard water accelerates scale (tank and tankless). Treatment and maintenance meaningfully extend life.

Usage Profile: Large families, recirculation loops, and high setpoints mean more run-time and wear. ( NRCan notes domestic hot water is a major energy load; efficiency and operation choices matter.)

Installation Quality: Proper venting, gas sizing, condensate handling, and combustion air (for gas) prevent chronic stress. ClimateCare members are trained to these standards.

Maintenance:

Tanks: annual flush; anode inspection every few years; test the T&P valve.

Tankless: clean inlet screens, verify combustion/venting, and descale per water hardness.

Tanks: Pros, Cons, And Real-World Life Expectancy

Pros: Lower upfront cost; simple, widely serviceable; works with existing plumbing.

Cons: Corrosion risk; standby heat loss; higher flood risk on failure; space required.

Life Expectancy: Plan for 10–15 years; replace proactively near the insurer’s age limit to avoid coverage surprises.

Maintenance Needs: Annual draining/flushing to remove sediment; anode checks; verify temperature/pressure relief operation. These steps reduce overheating and internal rusting that shorten life.

Tankless: Pros, Cons, And Real-World Life Expectancy

Pros: Long life potential (~20 years average); compact; high efficiency; endless hot water (within flow limits).

Cons: Higher upfront; needs correct gas line/venting; scale control is essential for longevity; cold-climate inlet temperatures may require sizing for peak flow or recirculation strategies.

Life Expectancy: 20+ years with proper servicing. Book annually at least.

Maintenance Needs: Annual professional descaling in hard-water areas; clean inlet water/air filters; verify condensate neutralizer (for condensing models). These help the heat exchanger last decades.

Heat Pump Water Heaters (Hybrid Tanks): Where They Fit

These units pull heat from the air to warm water but can switch to electric elements for faster heating. They’re “hybrid” because they use both air-source heating and electric resistance heating in one system.

Efficiency: Natural Resources Canada notes ENERGY STAR® HPWHs use up to ~70% less electricity than standard electric tanks—excellent for households on electric rates or looking to cut emissions.

Life Expectancy: Often similar to electric tanks for the storage portion, with added maintenance around filters/condensate and attention to room size/air volume. Choose units with accessible components and strong warranties, and lean on a pro for correct placement and noise management

Typical Warranties

Tank warranties are commonly 6–12 years on the tank/parts; tankless often carry long heat-exchanger warranties with shorter terms on parts/labour. A longer warranty usually reflects better materials or anode strategy—but water quality and maintenance still rule real-world lifespan. Dows ClimateCare can walk you through terms across brands so expectations match your home’s conditions.

Maintenance Schedules That Add Years

Annual Service: Provincial safety authorities recommend regular servicing for gas appliances to maintain safe, efficient operation.

Tanks (Every 12 Months): Drain/flush; inspect anode (every 2–5 years or per condition); test T&P valve; check venting/draft (gas).

Tankless (Every 12 Months, or 6–12 in Hard Water): Descale; clean inlet screens; verify combustion/venting; check condensate neutralizer media.

If you prefer “set-and-forget,” Dows offers w ater heater maintenance plans that schedule these tasks so lifespan isn’t left to chance.

Signs You’re Near End-Of-Life

Here’s what to watch for if you suspect your hot water tank is at the end of its life:

Age Threshold: At or beyond ~10 years for tanks (review insurance implications).

Rust-Tinted Hot Water

Rumbling/Knocking

Frequent Resetting or Pilot/Code Issues

Visible Leaks/Corrosion

If you see these and the tank is older, plan replacement before a failure. Dows’ own guide flags 10–20 years as an overall outer range depending on care and conditions.

How To Choose—No “One Right Answer”

Use this quick framework with your Dows advisor:

Household Pattern: Large families with simultaneous showers/laundry may need higher tankless flow, a recirculation solution, or a larger tank.
Water Quality: Hard water? Budget for treatment and descaling (tankless) or more frequent flush/anode checks (tank).
Space & Venting: Tight utility rooms, sidewall clearances, and vent routes can favour one option over another—Dows assesses onsite.
Fuel & Rates: Natural gas availability, electricity prices, and off-peak plans influence lifetime cost; HPWHs can shine on electric.
Risk Tolerance: If a basement flood would be catastrophic, a proactive tank replacement or a tankless upgrade may be worth it, given insurance realities.

Cost And Risk: Total Ownership View of Each

Upfront: Tanks win on purchase/installation cost. Financing is often available as well.

Operating Cost: Tankless and HPWHs typically spend less over time, especially with high usage. NRCan/utility guidance supports the energy advantage of tankless and HPWHs vs. standard tanks.

Failure Risk: Tanks can leak and cause water damage at end-of-life; insurers often enforce replacement age limits. Tankless failures are more likely to be no-heat events rather than damaging floods.

What To Expect On Installation Day (And After)

Site Prep & Permits: Proper gas sizing, venting clearances, and drainage/condensate handling (for condensing/tankless). ClimateCare members follow manufacturer instructions and Canadian codes.

Commissioning: Gas pressure/combustion checks, leak tests, flow verification, and control setup matter for lifespan and warranty.

Owner Orientation: We’ll review maintenance intervals (flush or descale), setpoints, and what to watch/listen for so small issues don’t become expensive ones. Then we can enroll you in a maintenance plan so it stays on schedule.
