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 Charlotte, NC, 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 All City Heat and Air, and we can set up an appointment to calculate the furnace size you might need.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient system. You can even customize it to better match your home's system for a more accurate calculation.

Gas Furnace Maintenance in Davidson, NC 28036

“First time use of All City. Our original installer was no longer maintaining our two Bryant units he installed. I went on Bryant's website and found All City as an authorized Bryant dealer. It had been almost 3 years since we last had a maintenance check. Tim and Sean came out and were very professional. They wore masks and put protective booties on their shoes before entering the house. They answered all of my questions and did a thorough maintenance check of our heating system. In our bottom floor unit, Tim found that the condensate pump had failed. We had that replaced and while they were here, decided to add some safety items that had not been installed in the original installation 13 years ago. I was so satisfied with their work, that I decided to signup for their yearly maintenance plan. In the spring, as part of this plan, they will come out and inspect our cooling system. Thank you All City!” – Gary C.

“January 2021 had a whole new unit installed. The guys that showed up were great in and out in 1 day. I had heat immediately and nice cold air all summer. I signed up for the annual maintenance plan to keep the warranty in good standing. Great price for the piece of mind. Had a technician come out for the 1st real check-up today and was extremely professional as all the staff has been. Highly recommend this company and staff.”
