It feels like spring is finally beginning in Kingston, Trenton, and Belleville, and not a moment too soon! Just a few weeks ago, much of Ontario was still covered with metre-high snowbanks. The arrival of warmer weather, not to mention increased hours of sunlight, has many of us refocusing on the outdoors: getting back into regular walk routines, setting up our patio furniture, and firing up that BBQ!


While you’re welcoming the new season, don’t overlook the mechanical appliances that got you through the winter. Now is the perfect time to show them some love, and make sure you’re prepared for the seasons ahead!

Test Your AC Early

You likely won’t need it yet, but making sure your AC ready to go for the summer is always a smart move.

Clean Your ERV/HRV Core & Filters

Getting fresh indoor air into your home, and getting the stale air out, is important for your health.

Check Your CO Detectors

It could save your life! Ensure your home stays safe by testing and replacing batteries as needed.
