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.

“Gagle’s has ALWAYS provided the best heating service in the area. I recently moved to a different home and called to have my furnace repaired. Jackson, a technician, analyzed the unit and repaired it. However, he told me that it would, likely, not last long. Since the charge was minimal, I decided to take my chances, but the furnace only lasted a few months. I called to have an estimate for a new furnace. Raymond came out a day later and provided me with a thorough and easy to understand estimate. I also asked 2 other companies for estimates, one company took several days to complete the estimate, the other only sent the estimate after I called 3 times. I don’t really know why I called the other two companies, I knew that Gagle would provide the best service. After selecting Gagle’s, Ivan and Armondo came out and installed the unit. They did an excellent job. NEXT, Jackson who is a computer expert, as well as a heating technician, came out to see if I had connected my phone to the internet and furnace correctly. I had not, so he showed me the correct way. Mark Gagle, the owner, then came out to evaluate the crews work. I explained that I was more than satisfied with every aspect of all work done, including my first contact with Jordan, including his contact with me. This company has the best customer service of any I know. Every person I dealt with was professional and very highly skilled. Mark Gagle’s ability to recruit and retain these amazing people shows just how dedicated he is to the company, the customers and our community.”

“The team from Gagle’s Heating, A/C & Plumbing were great. My 22 year old furnace had stopped working in February. I called Gagle’s and Raymond was able to come out to give me a bid for a new furnace the same day. The following week, 2 installers came out and was able to install the furnace in just a few hours. They explained everything I needed to know on how the new furnace operated. Then to my surprise Mark Gagle, the owner came over to inspect the installation and was able to adjust my existing Nest thermostat to work properly with the new Bryant furnace. I am one very happy customer.”

“Our Furnace quit working on Sunday. I called Gagle’s and spoke to Jordan, who scheduled a technician to come out. From my first contact, I felt the company had my best interest at heart. Jackson, the technician, arrived on time and proceeded to test the furnace. He diagnosed the problem and made the repair. His knowledge and expertise was readily apparent to me. He was very professional and made sure we were informed of exactly what he was doing. I have used Gagle’s before and have always been completely satisfied with their work. I trust this company, completely, and gladly recommend this company to anyone.”
