Tips For Using A Furnace During Extreme Cold Weather

Conventional furnaces are not designed for extremely cold temperatures. Thus, your furnace's efficiency might suffer when the temperatures go below zero. The following tips can help you enjoy efficient heating under such temperatures. 

Keep Consistent Temperatures

It is easier for the furnace to maintain a certain temperature than to raise the temperature to a certain level. Therefore, don't fiddle with your thermostat settings when the temperatures are extremely low. Ideally, you should set your target temperature when the cold season commences and leave it there for the duration of the cold season. You should even put the normal thermostat program on hold.

Don't Crank Up the Thermostat

It is tempting to crank up the thermostat when the temperature goes subzero. Some people think this is a good way to heat the house fast, but the furnace doesn't work that way. A high temperature setting only causes the furnace to run longer and strain, which reduces heating efficiency and increases the risk of furnace malfunctions. Therefore, avoid unnecessary temperature increases.

Keep Vents Clear

The furnace needs to vent outside, and it can only do this if the vent openings are clear. Unfortunately, snow and accumulation can block these vents during extreme weather situations. It's your responsibility to inspect the vents regularly and confirm that they are clear.

Use Fans for Air Circulation

Your furnace might need a little help to get the heated air moving during the cold season. This help can come in the form of a ceiling fan that helps to force the heated air down. The natural tendency of heated air is to rise since it's less dense than cold air. Don't forget to reverse the fan direction from the one you were using during the cold season when you needed hot air to rise.

Expect the Furnace to Struggle

Most furnaces are not designed to operate in subzero temperatures, so you should expect your system to struggle a little. The house might not be as warm as you want, but you should expect that so that you don't think it's a furnace malfunction. Rather, you should try to make the work easier for the furnace. For example, you should keep the doors and windows closed as much as possible to avoid heat loss. You can also try cooking indoors to warm up the air a little so that the furnace doesn't have to struggle to heat the house.

If your area experiences extreme cold weather, you should service your furnace before the cold season commences. That will reduce the risk of furnace breakdown when you need it most. For more information, contact companies like Scott's Heating & Air Conditioning Services.
