Called them when my heater in our sunroom went out. Two technicians came out and didn't seem to know what to do to repair it. They also didn't seem comfortable having us watch them. We let them do their work and afterwards they said they weren't sure what was wrong but would research and get back to us. A month passed and around $200 later we hadn't heard back. We called them and they didn't answer. Called again and they said they'd call back. Another month has passed and nothing. Went with another. (Our heater was new as of 2025, so it's not like they were working with some very aged unknown item. The ignition was bad and the other professional diagnosed it quickly. Got the part under warranty and we're back in business)
Our garage heater fan wasn’t working properly and with the temps being double digit sub zero and having our water heater in the garage, we needed it fixed fast. I called multiple companies and all were busy but HeatSource got back with me and were able to get me in the same day. They were very communicative and diagnosed and fixed the problem very quickly. Super friendly and informative. I will definitely use them again.
I had my heating system serviced for routine maintenance, and the experience was excellent. The technicians arrived on time, was courteous, and clearly explained each step of the process. They did a thorough inspection and made sure everything was working efficiently before leaving. My system runs better now, and I feel confident going into the colder months. Highly recommend their services.
HeatSource Mechanical was by far the most responsive company for my boiler replacement needs. They also sent an employee out to give me a proper estimate and fielded all of my questions. Sway worked with my needs and budget which I greatly appreciated. Communication was quick, I received updates when things changed and they seemed to genuinely care. Richard and Jason (instillation technicians) were timely, friendly and very informative when I had questions. They also accommodated my needs and wishes with the setup when applicable. They were also very welcoming to our pets. The new boiler looks great and I would work with this company again for any of my boiler needs. They were just good people all around, thank you.
We had an amazing experience with Heat Source Mechanical from start to finish! We had a service person (Joe) come, they agreed with us that the unit needed replaced rather than the many repairs it would need, they had an installation quote person (Sway) out within 2 hours instead of making us wait longer. We were quoted 2 options and they even helped us get financing. There were no smarmy tactics or upselling, talking circles, or saying they would get back to us later, just an honest review of our unit and what we could expect with the new one we were choosing. They even came back later that day with space heaters so we wouldn’t be cold until they could get here to install. The two installers who came to the house (Hayden and Sagun) were wonderful, they were considerate, knowledgeable, and they never seemed to stop working but they had fun laughing together while they worked which was awesome for my family to hear (who wants grumpy people doing work in your home). They completed the work in the 2 days quoted, and they did an amazing job cleaning up after themselves. We now have reliable heat, just in time for the snow that fell yesterday, and it’s nice to not have that stress and cold. We will definitely be using them again and I’ve already told neighbors who we used in case they need service.
