Why Orillia Homes Lose Heat Fast in Winter (And How to Fix It)
Orillia winters hit hard—and when temperatures drop suddenly, many homeowners notice the same problem: their homes just don’t seem to hold heat. Rooms feel drafty, the furnace runs constantly, and heating bills spike. At Mr. Heat Furnace Orillia, we see these HVAC Orillia issues every year, and most of them have simple explanations that can be fixed before the coldest months arrive.
1. Furnace filters clogged with winter dust
By December, most furnaces in Orillia have been running hard for weeks. Filters clog fast, making the system work overtime and reducing heat output. Changing your filter every 1–2 months can make a massive difference.
2. Leaky ductwork letting warm air escape
Homes in Orillia—especially older properties—are known for worn or poorly sealed ductwork. Warm air leaks into basements or walls instead of your living space. A quick duct inspection can recover a surprising amount of lost heat.
3. Thermostat problems in temperature-sensitive areas
Installing a thermostat near a cold draft, window, or door can cause your furnace to cycle incorrectly. Homeowners often think the furnace is the issue when it’s actually the thermostat placement.
4. The furnace itself is aging
A furnace nearing the end of its lifespan will struggle to keep up during extreme cold snaps. If your system is 15–20 years old, inconsistent heat is a big warning sign.
