Most furnaces use gas, to heat a home or business. The gas enters the furnace and is ignited by an ignitor. It then warms the air in the heat exchange chamber. The air is then blown into the ducts/vents to get through out your home. The exhaust gases are also vented out of the home during this process. Electric furnaces use elements or strips that heat up from electricity, to warm the air instead of a fossil fuel.
ENERGY STAR-qualified or High efficiency gas furnaces will have a minimum ratings of 83% and 90%. This makes them up to 15% more efficient than mid efficiency furnace . They achieve greater efficiency with improved features, such as:
- Electric ignition – which does not need a pilot light to be constantly burning all the time
- Newer technology in combustion that moves larger quantity of heat from the same amount of gas
- Better Sealed combustion that uses outside air for heating
Specify a sealed combustion furnace, which will bring outside air directly into the burner and exhaust flue gases (combustion products) directly to the outside, without the need for a draft hood or damper. Furnaces that are not sealed combustion units draw heated air into the unit for combustion and then send that air up the chimney, wasting the energy that was used to heat the air. Sealed combustion units avoid that problem and also pose no risk of introducing dangerous combustion gases into your house. Backdrafting of combustion gases can be a serious problem with non-sealed combustion units.
All HVAC systems will need some basic maintenance eventually repairs. To properly extend the life of your furnace, it is very important to do regular maintenance. The most important and simplest thing you can do to extend the life of your furnace is constantly replacing the air filters.
