Excellent service from beginning to end!! The whole process with Heatsource Mechanical was seamless and professional. Trey is amazing and really takes pride in his work. Took the time to talk and walk me through every aspect of the process and went above and beyond to make sure everything was not only working perfectly, but also be aesthetically pleasing. Worked fast, efficient, and clean from start to finish. Also really polite and professional. From the office staff to the technician, would definitely recommend Heatsource Mechanical.

My issue was a failed IBC boiler that I jury-rigged to keep operating: it's in an outbuilding running heating lines through a concrete slab 40 feet by 60 feet. Jesse noted on a previous service call that the power connection to the fan assembly is a common failure, and ordered a replacement assembly & harness. Today's service call was to do a complete tear down and maintenance on the boiler, and replace the fan assembly and power harness. The tear down uncovered a gasket that had eroded away, and a 50% clog in the heat exchanger, a labor intensive job to clear up. Reassembly and maintenance went smoothly. Today's service call also included annual maintenance on our house boiler. Heat Source Wasilla is the best, top marks for knowledgeable technicians, responsiveness, and courteous folks on the phones; all in all a well manged business.

Trey was our technician yesterday and he was absolutely amazing and helpful. Give this man a bonus! We felt he went above and beyond to help us figure out why our furnace wasn’t working. We will most definitely be using you guys for all our future furnace needs! Thanks Trey W. and HeatSource for helping us get heat back into our home 😊 much appreciation

We are very pleased with the work that technician Jesse performed for us today, 12/17/25. We are also pleased with the work performed in the past years by Heat Source Mechanical. The technicians have always been very knowledgeable, courteous and professional in their mannerisms. Though they have always been dependable, we’re hoping that we will not have to see them again.,…… under these circumstances of course.

Sway, Garrett, Richard, Sagun, and Jason all helped to install our AC unit for our home. I know, I know, AC in Alaska, but our home has no tree cover and the upstairs was unbearable. Now we can run the AC and cook without perishing from the heat! Great job, and great company!!!

“Trey was very professional and prompt. He thought outside the box and came up with a fik for now until I can resolve the problem. Thank you for getting me some heat at these cold temps”
- Tony H.

“Heat Source installed my furnace in 2022 and I paid $288.00 to get a annual maintenance service. It's been $288 in 2023, 2024 and this month it was $390.00, Why?”

- andrew P.

“Everything was wonderful! From the free inspection and estimate, to the removal of our old furnace and the installation of the new one. The gentleman that installed our new furnace were polite and informative. They worked quickly and kept me informed of the progress every step of the way. My family will have a warm and cozy winter now.”

- Andrea D.

“Had to get my furnace replaced and chose to use HeatSource, they did a great job the technicians were friendly and got the job done quick. I am glad that I chose to use HeatSource.”

- Melinda B.

“This is my first encounter with Heat Source. Jesse knew exactly what was wrong very quickly. He found problems that other companies had not found. What I really liked is that he explained what and why it was wrong, at my level of knowledge. Definitely calling them again if I get new issues.”

- Mike W.

“Sway and the Heat Source team were amazing, informative and caring. Everyone seemed real and that’s hard to find these days. They made a very difficult time a little easier to deal with. We would highly recommend them. We appreciated everything the team did. It was nice to work with wonderful people. God bless you all.”

- George P.

“Heat Source Mechanical has been my go-to for furnace problems and maintenance for several years now, and I always request Joe Gray.

Joe knows his business, communicates effectively, and goes the extra mile to insure problems are resolved correctly the first time. He anticipates possible problems and solutions and has the parts he needs on his truck– instead of having to go back to the shop to get them.”

- Christine F.

“Joe crushed it. He recommended service ideas/opportunities without pressure. Very transparent about the work and preventative maintenance. There’s a reason we use HSM as our go to for heating and cooling maintenance.”

- Robert H.
