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 AA-AIR Company, and we can set up an appointment to calculate the furnace size you might need.

“What an awesome & honest company! There was an issue/accident during maintenance that was rectified immediately & the cost for parts needing to be replaced was covered by the company. Every experience (general maintenance of existing units & install of mini-split systems) with this company has been outstanding. I highly recommend them. I initially used a competitor company & switched due to poor work & no shows on scheduled appointments.”

“I was expecting someone older. Instead this very young fellow came to tune up my heating system. I soon found out that Kreigh was very knowledgeable and professional. One of the unit had stopped working two days prior and he knew right away what part had faulted. I was very happy of the service I received.”
