Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost-effective and energy-efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money––we don’t want to perform repairs or service on an appliance that is in need of replacement.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Maryville, TN residents:

What Are The Different Types Of Furnaces?

Single Stage: A single-stage furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage: A two-stage furnace has two settings––full and half speed. This is a more efficient way to heat and provides for better comfort, because it can move the air at a slower pace.

Variable Stage or Modulating: A variable-stage or modulating furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, making this type the most energy-efficient type of furnace.

What Is AFUE?

AFUE, or Annualized Fuel Utilization Efficiency, is a measure of furnace-heating efficiency. The higher the AFUE, the more efficient the furnace.

What Size Furnace Do I Need?

We can calculate the correct size furnace for your home. The number of BTUs, or British Thermal Units, needed to heat your home is dependent on a number of variables. Contrary to what you might think, a bigger furnace may not necessarily mean more heating power for your home. Call us at A & L Heating and Air, and we can set up an appointment to calculate the furnace size you might need.

“Aaron and Josiah were prompt in responding to my situation. My heat had stopped working during the night. When they completed the repair and the heat started back up, the thermostat registered 54 degrees in my house. I can only imagine what it was before I started a fire in the fireplace, turned on a space heater and fired my oven up to 375. It was brisk to say the least! Aaron went to great lengths to ensure the repair was done properly and worked effectively. As well, he answered my questions and ensured my understanding. These two are professional, personable, knowledgeable and thorough, all the while maintaining Covid awareness. Thanks, Aaron, Josiah and A & L.” – Beverly B.
