Furnace Repair

Don’t get left in the cold! Is your furnace acting up, blowing cold air, or making too much noise? Our experienced team of professionals is here to keep your home warm and cozy. We repair all makes and models, and we will never try to sell you a service that you don’t need. 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 Salem, OR 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 Gagle's Heating, and we can set up an appointment to calculate the furnace size you might need.

“Devin came out on a high volume day (we'd just had a snowfall and sub-freezing temps). Our furnace was performing spottily, so we asked for a technician to take a look at it. He diagnosed the problem, but said to call back if the the problem persisted. It resurfaced, so we called and he came back and came up with a more satisfactory solution. It's been performing well since. He was very candid in his appraisal, and stuck with the job to come up with the satisfactory outcome. A very positive experience all around.” – Peter J.

“I have no idea how I found Gagle’s, but I’m glad I I did. I read reviews and had bought a home in Salem to rent, and had three places come for estimates. I bought the home at a super good price knowing that the furnace was not in working order. Because I was purchasing it from a realtor, whose mother had lived in the home- estate sale-we wanted and thought it was no big deal to get A/C also so it’d be an compatible unit. Gagle’s was more than accommodating. I loved speaking with Jordan on the phone and Raymond came for a look/see–sent his bid that afternoon. So impressed!! I have a Honeywell thermostat that I’d bought online to hopefully use–Super Simon–we didn’t want anything programmable. Everything was like “no problem!!” It’s a super quiet unit–works GREAT!! Love you guys!! We’ll remember them at Christmas when my girls & grand daughters do our holiday baking–Thanks again, Pam Thomas”
