Considering a new furnace installation? A furnace draws air in from the living space, heats it up and returns it to warm the home. At Apex Air, we specialize in furnace sales and installation.
Most furnaces use gas—either natural gas or propane. The gas enters a chamber, is ignited by the electronic ignition and warms the air within a heat exchange chamber. The air is blown into the living space through heating duct work and the exhaust gases are vented out of the home. Electric furnaces use heating elements, or strips, to warm the air instead of a fossil fuel source.
ENERGY STAR-qualified gas furnaces have minimum AFUE ratings of 83% and 90%, making them up to 15% more efficient than standard models. They achieve greater efficiency with improved features, including:
A sealed combustion furnace 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. Is it time for you to consider new furnace installation for your home?
Sealed combustion units avoid that problem and also pose no risk of introducing dangerous combustion gases into your house. A back draft of combustion gases can be a serious problem with non-sealed combustion units.
As with all HVAC systems, at some point furnace repairs will be necessary. To help extend the life of your furnace be sure to provide regular maintenance. For example, air filtration is critical to effective heating, so you should make sure to change or clean your furnace filters often and have your furnace professionally serviced before each heating season.
