Furnace Installation & Furnace Repairs

Like heat pumps, furnaces keep your North Carolina home warm in the winter and serve as an important part of your air conditioning system in the summer. In a furnace, gas or oil is combusted in a burner and then heat produced from that reaction passes through a heat exchanger where it is transferred to the air distribution system.

Single-Stage Furnaces

Your furnace and fan is either on or off. Pretty simple, huh? A salesperson can say that a single-stage furnace has multiple speeds. Why? Every home has a unique heat load that is supposed to be calculated for you by your heating and air conditioning contractor. The single-stage furnace does have optional speeds, but it is hard wired to one.

Two-Stage Furnaces

Two-stage furnaces are more efficient and more effective at heating your North Carolina area home. Furnaces are like light bulbs, they operate better if they are turned on and left on. If you flick a light switch on and off, over and over, that bulb is toast. The same goes for furnaces. Running at 65% for 9 minutes is better than 100% for 3 minutes several times an hour. It uses less gas and is easier on the machine.

Multi-Speed Furnaces

In single-stage furnaces, if you want your fan on for circulation - the fan is always on high. It is the only option. Not only is that hard on the utility bill, but a fan on high means the warm air is moving fast - warm air moving fast creates a cool breeze. In variable furnaces, the fan turns over slowly to maintain air circulation while being easy on the utility bill. By the way, most air cleaners and filtration devices are only active when the furnace blower is on. So the best way to utilize these accessories is to have a variable speed blower. Switching its blower fan from a/c current to d/c current only draws 1/10 the electricity.
