When having a new furnace installed, you must first select one that matches your particular needs. The first step in this process is to measure the heated square footage of your home and ensure the new furnace is the right size. Too small and it won’t provide enough heat on cold days. Too large, though, and it will cycle on and off, not providing even heat and putting unnecessary stress on the device.

Another factor to consider is the type of furnace you buy. Gas furnaces in Atlanta are among the most energy efficient, but not all homes have gas connections. Electric furnaces are also very effective, so if gas is not available, this is usually your best option. In selecting a furnace, you will also need to select one with energy efficiency that meets your needs. Gas furnaces have AFUE (Annual Fuel Utilization Efficiency) ratings of up to 98% meaning they use almost all of the fuel they consume for heat. For higher rated furnaces, however, you will often need to upgrade your flue liner and some other components of your home’s ventilation system.
