Michael D did an outstanding job of yearly maintenance, explaining what was needed as he completed his tasks. I would highly recommend him as a service technician.

I called Key after years of sub-standard service from a prior company. What a breath of fresh air to be treated like a customer that is valued rather than an inconvenience. I'm looking forward to years of quality future service from Key. Michael explained his diagnosis of the problem and suggested the most cost effective way to improve the serviceability of my system.

Michael D'Agostino from Key came out to fix my A/C and could not have been nicer. Super professional, diagnosed and fixed the problem quickly. Answered my questions and had a great attitude. I've always had a good experience with Key but he was especially kind and helpful.

Highly recommend for geothermal systems. Had our system check and found multiple issues that were repaired quickly and affordably. Mike explained everything that was wrong and made sure we knew what and how the system was being repaired.

Really happy I called when our oil furnace wouldn’t start. Matt was very knowledgeable and we have heat again. Update: Michael came to clean and service the furnace and did a great job as well.

Our compressor gave up at a bad time, when temperatures were about to drop sub zero. Key Heating didn't leave us stranded and responded quickly by sending out a team to assess the problem. After locating the part required to get my compressor back up and running, Michael was dispatched. Once he arrived he quickly recognized that the part wasn't the right size, but rather then just postponing the job, he reached for his phone and didn't rest until he located the correct part. He then began working on the unit while waiting for his colleague to arrive with the piece that would revive our compressor. Both, Michael and his colleague were very professional and knowledgeable. They went above and beyond the normal call of duty, so that we wouldn't be without heat. Great experience, which is why we will continue to give our business to Key Heating.
