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!!!

The guys are bad ass! Jason, Sagon and Richard installed a new furnace for me after being without heat all rainy summer. Christine and Maryann in the office were top notch. Customer service is obviously a priority for Heat Source Mechanical. Definitely recommend!!! 10/10 🌟

The Technician, Trey Williams did an outstanding job of diagnostics and repair on a tired, old heating system. After testing and cleaning multiple components, his "never quit" attitude resulted in finding the most difficult problem possible - intermittent failure. Although he tested the various components multiple times, it was when he caught the part in an intermittent failure that allowed him to complete the repair. The unlikely component and the near obsolete furnace meant that he didn't have the particular part needed to effect the repair. He quickly sourced the part in town and was able to get there and back in an incredibly short time. This was so important and fortunate for me because I didn't have to go another day or two days waiting on a replacement part. His determined efforts resulted in our HVAC being up and running resulting in a warm home this morning at a cold 26 degrees. Thankyou Trey Williams. Thankyou Heat Source Mechanical for your quick response and professional and competent Technician. If I could offer or request a change in your receipt process, I would like a semi-itemized statement. List the cost of the service charge, quantity of hours/time and cost, and list/cost of parts. In the likely event that I need future repairs, I will be able to show the next Technician what parts/service has been completed or parts replaced, and I'll know if I'm being severely overcharged etc. To be clear, I'm not complaning. Rather, I'm thanking you for getting my heating system up and operating.


“Contacted Heat source to see options for replacing my old forced air furnace. Dennis came out. looked at my system and together we decided my best options. The replacement furnace was acquired and an install date was set. Meanwhile my hot water heater went out. Heat Source came out an gave me an estimate on that also. They were able to send out a crew and replaced my furnace and hot water heater in the same day. Very Professional crew. All work was done in my crawl space. I received written estimates for both jobs. I was very happy with the services I received from heat source and would not hesitate to use them again! Steve O.”

“I would like to leave a review for JR, a technician from Heat Source Mechanical, who repaired my furnace. His work ethic is truly outstanding, and he completed the job efficiently and in a timely manner. As a senior citizen, I especially appreciated his kind, respectful, and caring attitude toward me throughout the entire process. He took the time to explain what he was doing and made sure I felt comfortable and informed. It’s not often you come across someone so professional, patient, and considerate. I highly recommend JR to anyone in need of quality service—he is a real asset to the company.”

“Customer Service – After the Sale
First, These issues were NOT with HeatSource
Mechanical, the issues were with several recently
Manufactured Product Defects.
Summary: Three (3) complete heating system installs
and 17 service calls to fix several Manufacturer Defects,
all under warranty that HeatSource Mechanical honored.

Let me explain.
HeatSource installed a Combi Heating unit some time
ago and since day one it did not work properly.
HeatSource, at my request, visited our home 17 times to
correct the issue(s). At one point HeatSource replaced the
complete Combi Heater with a new like unit at no charge.
The issues with the newly installed Combi Heater were
still present and frustrating. HeatSource was just as
frustrated about the issues and had been on the phone
countless times with the manufacturer trying to resolve
the issues with no end.
At the end of last year (2025) the manufacturer, with
no warning, closed their operations in the United States
and left America. This left thousands of companies in the
USA with no way of warrantying their products or with
access to parts for repairs.
This is where it gets good! I received a call from the
owner of HeatSource asking me to come in for a meeting
on my situation. The owner, Denis, offered to replace my Combi unit with a completely different manufacture’s,
heating system, at no cost to us. When I asked, why he
was willing to do this after the original heater manufacture
left the country, he replied, “Some time ago, I wrote to you
that I would not abandon this situation, because I believe
in our ‘customer satisfaction’ as a first priority”.
Then to further solidify that statement, I found that
Denis had purchased, from an Alaskan supply company,
all of their new and now defunct heater parts. This was
done so HeatSource could now honor the “warranties” to
his customers of the extinct manufacturer. Again, showing
his commitment to “customer satisfaction being his
number one priority”.
If your looking for the “old fashioned company” with
core values, that show they stand behind their products,
after the sale, just like your Grandfather may have talked
about in the era of: “Your handshake is only as good as
your word” & “Your word is as good as any contract”,
HeatSource is that present day company.
Ending Note: Two days after my meeting with Denis, our
new heater was installed by Richard and Jason. They did
a superior and professional job.
Our heartfelt thanks to: Denis, Mary Ann & Jesse. All
outstanding in their commitment to customer service
Randy and Joanne”

“Heatsource Mechanical has been so good to me and my family! When our heat went out in the big snow wind storm of 2022 they were the only company who would come out and see what was going on. I have had them out to my home on multiple occasions and have never had a bad experience! They are very responsive, knowledgeable, and care about their customers! I would recommend them for any of your heat needs! Thank you Heatsource Mechanical for always taking care of my family’s heating needs!”

“Jesse was professional and efficient. He also was very good at informing us about our system. They are highly recommended.”
