Heat Pump Installation in Barrie, Orillia & Simcoe County

A heat pump is one system that does two jobs: it cools your home in summer like an air conditioner, and in cooler weather it runs in reverse to heat it. Because it moves heat rather than burning fuel to make it, it runs far more efficiently than a gas furnace through the mild and moderate part of the season — which is most of the Ontario year.

The honest catch is the deep cold. A heat pump works hardest, and least efficiently, on the coldest nights — so the real decision for an Ontario home is not heat pump or no heat pump, it’s how to set one up so it carries the season and still keeps you warm at -25°C. The three choices below are how we do that.

Set up correctly, yes. A cold-climate heat pump will carry the large majority of your heating hours on its own. The coldest stretches are where the backup earns its keep — in a dual-fuel home that's your gas furnace, switching in automatically below a set temperature (the “balance point,” often around -10°C to -15°C). You stay warm; you just heat with whichever fuel makes sense for the weather.

The other half of getting it right is sizing. A heat pump has to satisfy two loads — summer cooling and winter heating — and they pull in different directions. We size with a proper heat-loss calculation (CSA F280) rather than a square-footage guess, then set the balance point for your home and your heating fuel. Oversizing hurts summer humidity control; undersizing leans on the backup too often. Getting that balance right is most of what separates a heat pump that delights from one that disappoints.
