No matter if you’re just interested in lowering your energy bills throughout the cold season or if your furnace is aging, it is important to learn about the different types of forced air furnaces. With the various choices you have, we at Agape Air Conditioning, Heating & Plumbing would like to share the different types of furnaces.
Basic Furnace Differences
Having several important differences between furnaces and how they operate gives more options. With more control over how much heat they generate, there are some furnaces run in two different stages and there are some single stage furnaces that create as much heat as possible. A furnace’s other main differences is the function of their blowers. What moves the generated heat across your home, is the blower. During use, this major operational difference affects comfort and efficiency, where others run their blowers at variable speeds.
Single VS Two Stage Furnace
The older furnaces are generally single phase, generally indicating heat generation at their maximum level all the time. This isn’t necessarily a bad thing as it makes the furnace more affordable. Known for being more efficient, the two stage furnaces often operating with an AFUE (annual fuel utilization efficiency) above 95% efficiency levels. These two types of furnaces have major efficiency differences due to how they operate. Furnaces are at their most efficient following through the warm-up phase and operating for longer periods. When it comes on and shut back off again it will warm your home with a single-phase furnace. To warm your home, a dual phase furnace comes on at maximum power during the coolest period of the day. After your home is warm, it doesn’t shut off within a single degree or two of the thermostat’s settings, but it lowers to the low heat output level and continues to run and work to keep heat levels. A two-phase furnace continues to function efficiently to maintain your home at comfortable temperatures by simply cycling between the high and low heat output levels by continually running.
Variable Speed VS Standard Furnaces
The standard furnaces have blowers that run at the same power level all the time is how a few furnaces perform. Some furnaces operate with a blower that speeds up and slows down, depending on how much the temperature of your home needs to be increased. The blower runs at a slower rate making it use less electricity and creating a more comfortable environment when the house only needs a small bump in warmth. Additionally, this style blower is shown to have a longer operating life allowing you to keep your home at comfortable levels for years longer than your basic single-speed blower ever could. Delivered with a variable speed blower, the right amount of heat with precision and is often paired up with a two-stage furnace for peak efficiency.
