Emergency service call on Christmas Eve. Our boiler malfunctioned. Technician Mike Ring did everything he could to get the boiler motor to work, but it was too late. We appreciated his prompt response and knowledge of the problem. We will continue to use Key for our HVAC needs going forward.

Service inspection was completed on 10/14/21 by Jimmy Campbell. All I can say is that he was EXCELLENT! Would highly recommend him. He went over and above explaining to me how the heating system works. He also pointed out red flags to watch for. For example, what the recommended psi and temperature guages should read when the system is running. We could not have had a better tech. Thank you for sending him.

A complete disaster... we spent good money on a brand new A/C system and they did not install it correctly. They kept sending service people over who agreed it was not correct, but no one did anything about it. They were supposed to come over and meet with my wife to cover everything, appointment was made weeks in advance on her day off and the completely ghosted her without any communication..... could be the worst company I have ever dealt with, unprofessional and basically flat out liars.... would love to see them dispute any of this as i have the complete email chain..... Buyer beware!!!!

Justin was prompt, knowledgeable, skilled, efficient and polite. He took the time to explain a few issues and recommended some options. He also stayed longer to make sure the system was operation properly when by chance our thermostat called for heat a few seconds after he completed testing the high temperature shutoff setting and the boiler fired back up. He determined that indeed was the case, but it did take him an extra effort.

Warning - if you need service, these guys will be completely unreliable. The put an emphasis on Sales over Service. Case in point, their service department is run by the Installs Team.
We had a Mitsubishi mini split system installed in two units in our duplex. In both units there was a leak in the system! The first was found in the first year, which they fixed. The second was found in the second year. They failed to fix that properly. Now, three years in they refuse to come out and address the issue in the second unit. Now we need to pay hundreds of $$$ for another company to come fix their mistakes

We have used Key Heating & Cooling for over 7 years. In our recently construction (in-law) home, they installed the heating and cooling systems. They now maintain and service it yearly.
We decided to use KEY again to install a 3 head Split System AC/Heating system in our second home. Marie, Matt and the crew are amazing. They are friendly, fast, efficient and knowledgeable. They are a well oiled team. They come with everything they need - no waiting around for parts from China. Their prices are competitive but let's forget about money and show loyalty to our local small businesses. I highly recommend

A great installation experience. Everyone I had contact with from Marie who performed a walk around and estimate, to Pete and Tim who installed the split systems, all were very professional and explained everything as they proceeded. Their work (and work ethic) is excellent. Would not hesitate to recommend them to anyone wanting to install a split system.

We had such an amazing experience with this company. They literally just left after the final installation today, and wanted to write this review to share what a positive experience we had. I wanted to post this review to help others who are searching for a heating and air conditioning service. From day one when I initiated the first call to set up service, I spoke to three different people in the process and they could not have been any kinder and sincere. They thoroughly answered all the questions we had. If they promised us a phone call,they would call back very promptly. They performed the
