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!!!

“I'd like to share my experience with HeatSource Mechanical today.
I had a young man named Thomas Grato , a technician come to do annual maintenance on my boiler system. He was very thorough, explained everything in detail, was very polite and courteous. He cleaned and checked everything, measured output for efficient exhaust etc. I am very happy with him, and the service he provided. Thank you Thomas, and HeatSource Mechanical! You're my new go to for anything boiler related! A++”

“Great service as always and super easy to schedule appointments. My technician Joseph came out for annual maintenance, replaced a component that was starting to wear out, and installed a surge protector on the gas furnace. This is wind alley Palmer after all. Heat Source has been my go to for several years now. Thanks again!”
