Single-Stage vs. Two-Stage Gas Furnaces in Asheville

During fall and winter months, your HVAC system keeps your home warm and comfortable. Most systems do this with a gas-operated furnace, which can provide reliable heat. But not all furnaces are created equal.

Gas furnaces come in single-stage and two-stage models. These furnaces perform different functions that affect the quality of heat your home receives. If your older gas furnace isn’t getting the job done, you may find that upgrading to a two-stage furnace will keep you warm all through fall and winter. Sheer Comfort Heating and Air Conditioning can provide expert advice for you and your family.

Difference Between Single and Two-Stage

Furnaces have a valve that allows the flow of heat-providing fuel. In single-stage furnaces, this valve only has open and closed settings. This means that heat either blows at full blast or not at all. Valves in two-stage furnaces have a halfway setting in between fully open and closed, offering the ability to blow moderate heat. This can provide more even temperatures in your home and save your money!

Which is Better For My Home?

Two-stage furnaces have the major advantage of efficiency. Single-stage furnaces will pump heat at full capacity, regardless of how cold it is inside. During milder Asheville winters, you may only need a small amount of heat to fully warm your home. Two-stage furnaces won’t blow more heat than is needed, reducing wasted energy and lowering utility bills. They also provide more even heat. Single-stage furnaces have constant on and off cycles that leave your home overly hot or cold. A two-stage furnace will eliminate this cycle, consistently warming your household.

If you feel you’re not getting the most out of your HVAC system during colder months, consider switching to a two-stage gas furnace. These furnaces will keep your home warm and comfortable through the fall and winter while saving you money each month.
