Buying any major appliance is a big investment that requires careful planning and all the proper information so you can make an informed decision. That’s especially true for the one appliance that regulates your indoor air quality and temperature more than any other—the furnace. When you’ve made the decision that it’s time for a new unit, there are a few questions to work through so you get the new furnace that suits both your needs and budget. One of the more important factors is size. Most of the units on the market today can provide more heat than the average Canadian house will need. The coldest day of the winter is a good benchmark to see if the furnace you have is the right size since it will be running almost continually. A unit that’s too big will run only for a short time during the same cold day and although that might seem energy efficient, this oversized model is not working at peak efficiency. A home heat loss calculation is the best way to get the proper sized unit. Getting a contractor to look after crunching these numbers for you is the best way to get professional results. Considering the latest in innovation is another step. Although single stage furnaces have been the norm for decades, multi-stage furnaces have some distinct advantages like differing levels of burner function and a modulating circulation fan to better move the heat around your home. Although these multi-stage units may not increase efficiency they are quieter, and allow for unsurpassed comfort in your home holding the temperature closer the temperature set at your thermostat.
