Knowledge HVAC has my appreciation! They were very responsive and the heat pump repair was diagnosed and fixed flawlessly. Joel was a pleasure to work with. I will use them again for all my HVAC needs.

Jo was very courteous and professional. I appreciate the work he's done. Very thorough. As he was working he explained the process and what his plan is.

Picked up this machine from an auction. Thought it worked but no luck. Changed numerous parts and still failed. Called these fellas and a couple hours later had a tech on it. He analyzed and diagnosed the problem quickly and efficiently then solved it with no additional parts required.

As the name indicates, Joel is very knowledgeable and efficient in his work. His response time is quick and accommodates my schedule. He cares that the homeowner knows exactly what the issue is and recommends the best solution regarding price and equipment. I highly recommend this company!

Joel was professional, knowledgeable, courteous and well prepared for Covid safety measures. Joel even identified a safety concerns in the outflow vents. Thx Joel I would highly recommend using Knowledge HVAC and Refrigeration

We have never had a more professional, honest company man work on our buildings than Joel. I usually don’t recommend trades as after a few years the service isn’t what it use to be. But not this company !!!! I HIGHLY recommend them Joel has done our home for years and is now doing our commercial buildings as well Thanks Joel for being a TRUE PROFESSIONAL who can be trusted All the Very Best

We thought Joel was very professional, he did a good job explaining things to us and when he left we had a running A/c, so was a good experience overall

I had Joel come to repair a broken furnace. He phoned to move up his scheduled appointment, which was good as we had no heat. He installed the new parts and cleaned the blower fan (he cleaned the fan for no charge). I was happy with the work and was happy with the cost of the work. Joel was great and I would have him back if I required more furnace work.

Very well done. It was perfectly done and functioning perfectly. He is a very friendly guy.

I highly recommend knowledge hvac & refrigeration to anyone. My heat was not working, Joel came and figure the problem in no time. I am impress how knowledgeable he was and that he took the time to explain what was wrong. This is a great company to use.
