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 Santa Rosa, CA 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 Enviro Heating & Air Conditioning, and we can set up an appointment to calculate the furnace size you might need.

“I was beyond amazed with the excellent customer service we received from Enviro. Our school was freezing and they came to us the very next day to analyze the situation and get the parts ordered. The next day when the parts had not arrived in Santa Rosa the gal in the office drove to Fairfield to pick them up!!! Who does that?!”– W F.

“I have to say, Enviro is the best. Heater broke down on a Saturday morning when it was about 30 degrees. Enviro was able to come out on Sunday, when the other 20 companies that I called could not. He had my furnace up and running again within an hour and made sure it was running properly. He had the part needed with him on the truck and got it up and running fast. Very happy with their service.”
