Tip & How-To about Heating & Cooling
Two stage hot air furnaces can save you money and make your high efficiency furnace even better. With your furnace running at low fire instead of cranking up to the highest heating output in mild weather you can be more comfortable while saving money.
Many people think that they are getting the best they can get by buying a high efficiency single stage furnace. What they often don’t realize is that they could do better yet and for a few dollars more have a high efficiency 2 stage furnace that could keep them much more comfortable.
There are 2 stage hot air furnaces that are now available that will only run at half fire if the full fire is not needed. With a two stage furnace in mild weather when only a little bit of heat is needed, the furnace will have longer run times on low fire. This will keep you room temperatures from getting too hot before the thermostat reacts and shuts the furnace off again. This will help to keep your temperatures from overshooting the set point and help to keep your home much more comfortable.
Many of these two stage furnaces also have variable speed blowers that run at a lower speed when heating on low fire. This will also help to save money on your electric bill, because these blowers use very little electric when running at these low speeds. Air noise from the blower running at a high speed is also reduced.
If you are thinking of replacing or installing a hot air furnace, make sure that you ask your contractor to give you a price on installing a two stage furnace. The price difference probably will not be much higher than a high efficiency single stage furnace. However the comfort of the two stage furnace coupled with the electric savings will make the extra money well worth it.
