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 Florence, SC 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 Quality Service Company, and we can set up an appointment to calculate the furnace size you might need.

“We came back from 18 days in Florida, just as a cold spell hit and our furnace was out. Thanks to Hunter for quickly diagnosing the problem and getting it fixed on a day when the temperature is forecast to fall to 22 degrees. Two nights without heat made us very grateful for the quick, efficient service. Hunter is also a pleasant man to deal with.” – Will W.

HVAC System Replacement

“On 8:00 on Sunday morning, our system failed with temps going down into the teens. I called the company I had used for over 30 years. After an hour with no response and a second call (still with no response), I contacted Quality Service Co. Luckily, my system came back on so I did not require an emergency call but I still called to have Quality to check it on Monday. They called at 7:30 a.m. to set up a time and had a tech at my house an hour later. Matt determined the issue and even checked on warranty for me. We decided to check into replacement instead of repair. Allen Duffy was at my door an hour later. He presented me with a proposal including payment options and information on the complete system. We made the decision to replace. Allen ordered our new system with a promise of installation on Tuesday.

At 8:03 Tuesday morning, the team pulled in my driveway ready to begin work. The work was completed later that day. Allen also came back to help me get acquainted with the new programmable thermostat. Today (Wednesday) he came back and installed a surge protector on it. He brought all of my paperwork which included the forms for Energy rebates. They had already been filed. In addition, the installation team replaced the pad underneath the unit as well as cleaning and mulching around the unit. They also replaced the breaker in the breaker box because ours was too large.

Their work was superior and I was treated with the utmost respect and courtesy by every employee during the whole process. I cannot thank them enough for all of their assistance. Everyone helped make the process as painless as possible. I was new to their company but they treated me as if I was a long-time customer. I highly recommend them. You will not be sorry.”
