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!

“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.”

“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++”
