Do you need to replace your furnace? If so, the kind you select should depend on a number of factors, including the size of your home, the existing ductwork and insulation, and your budget. Here’s what you should know about furnaces before you purchase one.

Furnace types

There are three main types of furnace to choose from:

  • Single stage. The most basic type of furnace, a single stage model only has one setting. These furnaces are designed to run at a constant speed and generally make more noise than other options. However, this kind of furnace isn’t suitable for Calgary winters. Though they’re inexpensive to purchase and install, single stage furnaces don’t heat efficiently enough to battle our long, cold winters.

  • Two stage. This type of furnace has more options than a single stage furnace. A two stage model run at about 65% of its full force most of the time, which generally provides enough heat for a home during moderately cold periods. When temperatures drop lower, the second stage activates a high fan speed, spreading more heat than usual. This kind of furnace is more expensive than the single stage variety, but it’s better able to heat a Calgary home and requires less energy to run. Additionally, because it’s not on at full force most of the time, it tends to make less noise.

  • Modulating. Using advanced heating technology, a modulating furnace delivers even heating throughout your home. This furnace’s power output can increase or decrease at 1% increments, allowing it to operate at peak efficiency at all times. A modulating furnace is the most efficient type of furnace on the market. This means that by investing in one, you’ll save money on your energy bills. It’s an excellent choice for Calgary homeowners looking to keep their home at a consistent temperature all winter long.

Fuel types

Another factor to consider when choosing a new furnace is the energy that’ll be used to run it. Electricity, natural gas, oil, coal and wood are all commonly used fuel sources for home heating. The best option for your home will depend on a number of factors, including cost and the energy source that’s currently used to heat your home.
