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 Sumner, WA 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 Dr. Cool, and we can set up an appointment to calculate the furnace size you might need.

“Called on a Tuesday to schedule an appointment. Mark came out and provided a quote the next day. He was very knowledgeable, no pressure, and enjoyable to talk with. The next day (Thursday), Nick and David installed the new Daikin DC96VC furnace and they were friendly, professional, clean, and performed quality work. Nick made sure to walk me through the furnace functions and maintenance plan before he left. I will definitely recommend Dr. Cool/Dr. Heat to my friends and family.”

Gas Furnace Repair

“The heating furnace in our home was not working this morning and so I called Dr. Cool. Luckily they had a service tech available due to someone else’s cancellation. Sean showed up approximately 1 hour after I called. After his assessment he had to go and pick up a part (motor) which he didn’t have on him. Upon his return it was only a matter of minutes and the heater started up. We would definitely recommend their service.”
