Autumn Home HVAC Checklist: Prepare Your System for Cooler Weather

Across Eastern Ontario, the evenings are getting brisk and the leaves are changing colours. Indeed, autumn has arrived! After a hot summer for some of us, it’s a welcome change. It’s also a transition period for your home’s heating and cooling system, and a perfect time to check in on it to ensure it’s ready for the changing weather ahead. Regular HVAC maintenance by a licensed technician is essential to keeping your system in good working order and extending the life of your furnace or heat pump. It’s also an important safety measure, particularly if you’re heating with fuel like natural gas, propane, or oil. Proper maintenance may be required by the manufacturer of your furnace or heat pump to maintain your warranty, and in some cases, by your home insurance as well. No matter the situation, now is the ideal time to act. Here are a few helpful tips to keep your home safe and your HVAC system ready for fall:

Filter Change

If you’re using 1” filters like those sold at hardware stores, inspect and change your filter at least once a month. Increase this frequency if you have pets or have been doing renovations in the home. Using a pleated media filter (usually about 5”) can generally last an entire heating or cooling season, sometimes even longer. This simple HVAC maintenance task is one of the most important ways to ensure your system works properly and avoid costly repairs.

Test Early

Autumn weather is generally very agreeable. Many of us haven’t yet fired up our furnace or switched our heat pump to heating mode, and we’ve stopped air conditioning our homes as the extreme heat of summer fades. Don’t wait until the last minute! Even briefly, test your heating system to ensure it’s in good working order and reliable when you need it next. Strange noises, unusual smells, or system issues? No problem! Our team is here to help! Call Dows ClimateCare now before the busy season arrives. When the time comes, switch your thermostat from cooling to heating mode, and adjust any registers as needed.

Smoke & Carbon Monoxide Detectors

Nobody plans on emergencies, but being prepared is smart. Test every smoke detector in your home — at least one per level — and ensure batteries are fresh. Likewise, have a carbon monoxide detector on every level and test its functionality. These devices have sensors that expire over time (usually 10 years), so check the expiration date and replace units as needed. Proper home safety checks are a crucial part of autumn maintenance.

Go Green

If you’ve been considering an upgrade, this winter is the perfect time to reduce your carbon footprint by switching to a clean, electric heating solution. Modern heat pumps are far more efficient than older electric furnaces or baseboard heaters, often doubling or tripling their efficiency by leveraging outdoor air heat, even in frigid winters throughout Kingston, Trenton, Belleville and Quinte West. It’s a smart choice for comfort, energy savings, and sustainability.
