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 Bellingham, 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 West Mechanical, and we can set up an appointment to calculate the furnace size you might need.

“Our experience with West Mechanical was excellent. Our 30 year old furnace finally gave out and with one call, Stephanie was at our door the same day to help us figure out the next steps. She quoted us two options on the spot, gave us an easy understanding of benefits of both options, and scheduled our furnace replacement within the same week. Ryan and his assistant showed up exactly on time smiling and ready to go to work. By early afternoon we had a new furnace and thermostat. Ryan gave us a full introduction to the system, showed us how easy it was to program the thermostat, and let us know they stand by their products and labor for a very long time. The service was outstanding! I'd recommend West Mechanical to everyone.”

Gas Furnace Replacement in Ferndale, WA 98248

“Our furnace broke at the worst time. Snow on the ground and 20 degrees outside. These two showed up a little early on Tuesday knowing my wife was scheduled for surgery on Wednesday. This team worked hard to get the new furnace installed as quickly as possible. They came at eight and were done by noon. That is, old furnace removed and the new one installed mess cleaned up and gone by 12:30. I turned the heat on and got my wife home from the hotel we had been staying at for a week. She had the surgery as scheduled thanks to the whole west mechanical team getting this job done. We could not be happier and I would recommend this company to anybody. Including my mother, and I love my mother. In short we were amazed by the whole team.”
