The True Benefits of a New Furnace System


Indianapolis Heating Average Life of a Furnace

Replacing and installing a furnace in your home is one of those necessities in life that is unpleasant to consider, but ends up providing surprising benefits to the comfort of your home.

Most furnaces last an average of 14 to 20 years, so if your furnace is in that age range but is still operating properly, you may want to consider purchasing a new unit because of greater increase in the operating system efficiencies.

Quality furnaces built and installed during the 1990s have fuel efficiency ratings of around 80 percent, or maybe even less, meaning that only 80 percent of the fuel burned heated your home, while the rest went up the chimney or flue as waste. Today's systems have fuel efficiency ratings of at least 90 percent, with some going to 95 percent or higher.

Going Beyond Energy Savings

Obviously, with increased fuel efficiency, you won't spend as much money on utility bills after installation of a new furnace. Benefits go way beyond utility costs, however, as today's furnaces produce fewer greenhouse gases because of their fuel efficiency and thus, are kinder to the environment. In addition, most older furnaces are one-stage units, meaning that the furnace burns full at full capacity all the time.

Two-stage furnaces have an intelligent module that can detect how much heating is needed in a building as determined by outdoor temperature. Operation in this manner results in more even overall comfort, avoiding the wide temperature swing that one-stage furnaces provide. Although these units turn on and off more frequently in colder weather, they also operate more quietly and are less obtrusive to the indoor environment.

Indianapolis New FurnaceProper Sizing is Essential

Before you even look at the different furnaces on the market, make sure your chosen contractor sizes your home to make sure that you purchase the correct type of unit.

A Manual J residential heat load calculation is essential to this process as it not only takes the size of your home into consideration, but also other factors such as geographic location, orientation to the sun, envelope tightness, duct leakage, lights and appliances and even the number of people living in the dwelling.

Once these calculations are performed, you can properly select your system on your contractor's advice. Furnaces that are too large or too small will cycle on and off frequently, resulting in decreased efficiency.
