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!!!

“Several weeks ago your technician Joe completed annual maintenance on our furnace and hot water heater. He arrived as scheduled and was familiar with our systems, having been here before. He completed the necessary maintenance and discovered a couple of issues that he recommended be addressed. Joe is clearly knowledgeable as well as professional and courteous. He explained things in a way that I could understand, and patiently answered all of my questions, By the time he left all work was complete and everything has been working great. I feel Joe really went above and beyond, not only in the way he completed the technical part of his job, but also in how he went out of his way to be helpful and make sure all of my questions and concerns were addressed. He certainly is a good representative of HeatSource Mechanical. Thank you.”
