Our technicians are honest and hard working, and we’re always transparent and fair about the work we do.

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 Kingston, 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 Central City, and we can set up an appointment to calculate the furnace size you might need.

“Yesterday Richard Sampson came to perform our first maintenance on our new Trane unit. We did not think our thermostat was working properly. He discovered two issues while he was here. One was that the 2nd stage hose was not connected, and two that the thermostat was not sealed properly.  In spite of fixing these two issues, he determined the thermostat still needed to be replaced.  

Richard was very thoroughly and knowledgeable with his diagnostics. I highly recommend him and prefer to have him come to our home to perform all future maintenance.”

“Corbin showed up right on time, was professional with a great personality. He did a thorough check of our gas furnace. I enjoyed the experience of his being here and making sure we're good for the winter season. Central City's technicians and installers have always done a fine job on our heating and air conditioning installations and service. Corbin is a good addition to the staff.”

“Shawn and Brad did an excellent job installing our new HVAC unit. They showed up on time, finished the job on time, and were courteous and friendly. Very professional! We are very satisfied.”

- John C.

“Chris and Shawn came to hopefully fix my new unit. They did a great job. Very kind and respectful. Hopefully the new unit will work better when the temperature goes over 80 degrees next summer.”

- Ann D.

“I can’t say enough good things about my experience with Central City. From the office staff, the technician who came out to evaluate the problem, to the sales team, the installers, and every person I had any contact with…everyone was polite, knowledgeable, fair and honest.

The technician took a great deal of time explaining everything that was wrong, what my options were, and the reasons for his recommendations. The salesman was wonderful and worked with me to figure out the financing. The installers were great, as well. They were fast, efficient and cleaned up thoroughly when they were finished.

I contacted several companies before deciding on Central City. After meeting with them I felt that they were completely trustworthy and I would be comfortable having them in my home. It was a good choice, and I highly recommend them.”

- Ellen A.

“The service was great. Had been without air and heat for a year a friend told me about Central and I got in touch with them. They were able to give me financing advice and now my air is fantastic.”

- Beth C.
