They were able to get me same day. Im sure I got lucky on thst one. Great service from the office to the technician Joe that came out. Always recommend them if anyone asks. Top notch!
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
Prompt service was able to schedule next day service for installation of a water tank. Technician was informative, polite and timely.. I appreciate that they call and text when service person is in their way.
Fast service
Worker had sense of urgency
They were doap like soap on a roap!
I will continue to use their services!
We had an incredible experience from start to finish. They installed a new furnace, garage heater, and water heater for us, and the entire process was seamless. The team was professional, punctual, and extremely knowledgeable.

The quality of their work is outstanding. Everything was installed cleanly and efficiently, and you can tell they truly take pride in what they do.

Highly recommend to anyone needing HVAC work. We will absolutely be using them again in the future!
Joe comes to our house every year and services the furnace. He is so knowledgeable and truly the best.
Heat Source's Technicians always do a great job and leave you with confidence!

“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.”

“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.

“Joe and the team at Heat Source are great to work with! They’re friendly, knowledgeable, and were able to come out and fix our heating issue quickly. Very happy to reach out to them in the future with any other heating needs.”

- Josi B.

“Trey and Tyler were respectful, thorough and helpful. Trey answered questions and was able to demonstrate knowledge of my natural gas boiler, giving me better understanding of how it works and how to navigate the operating system. Their annual plan for maintenance helps streamline things as well.”

- Ginger T.

“Overall pleased with their work, diagnosis of the issues and the installation of the new system. The two techs that installed my new furnace were friendly, professional and did an amazing job.”

- Tabitha V.

“Anthony Gazaway worked with me extensively to select a profane furnace that worked for my cabin. He was knowledgeable, responsible and had excellent follow through. Hayden Morin and his team installed the furnace a in professional and efficient manner. They communicated very well with as what they were doing, checked with me on options and were friendly to work with. Chisty worked with me on scheduling and was prompt and friendly in doing so. All in all, it was a delightful experience working with this company; I very highly recommend them!”
