We had a great experience using Key to install a new furnace, heat pump and duct work to our home. Everyone from the office staff to the field guys were very responsive to all of our questions prior to the installation through completion. Jon presented us with several options for heating and cooling and explained the pros and cons of each, helping us make the right choice for our home. We would definitely recommend using Key Heating and Cooling! Thanks guys!!

Keith P was fantastic. Very personable and extremely knowledgeable. I had double trouble - furnace fan had died, as had the hot water pressure valve. He explained everything in layman’s terms and though he had to leave and return with another part several hours later, he was just as pleasant at the end of the day as he was when he walked in the door that morning. Would totally recommend Key Heating & AC in general and Keith P in particular. In addition, the office staff is terrific - both Laurie and Karen were wonderful.

Walter was pleasant, professional and prompt! Diagnosed the problem quickly and the repair was done ASAP. We have a geothermal system that requires a different diagnostic skill set from our oil based system. Key technicians have this knowledge and are always able to answer questions.

Walter was punctual, knowledgeable, and was able to resolve our issue quickly. He didn't seem to mind me observing his work and asking questions, which was nice. He clearly explained the issue, how he resolved it, and a plan of action to move forward.

Fabulous work! Great Customer service. I highly recommend to anyone. Do yourself a favor and call them. Don’t waste time with anyone else. Keith P. Was amazing and will be looking forward to seeing you in the fall.

Keys Heating & AC were fabulous when installing our new central AC. They are professional, courteous, and very pleasant to have in our home. I would recommend them to anyone. They are punctual and kept me continuously updated on their progress. It was a pleasure to work with them.

Keith did a wonderful job explaining what was going on with my furnace. Taking the time to go over how when hearing loud banging noises from the furnace means there is air in the lines. Keith was quick to fix this problem and pointed out some potential parts should be replaced at the next cleaning. Very please. Scheduling Dept. was very quick to get me scheduled for an appointment too. Great team work all the way around.

Key Heating and Air Conditioning recently installed a new propane heating system and heat pump at our house in New Hampshire. Our primary residence is in Pennsylvania so there was a need for close communication throughout the process. Key staff were excellent at keeping us informed of the equipment delivery and installation schedule and everything went according to plan. The actual installation of the new system required nearly a week of work. Matt B, our installation manager and his staff were professional, hard working, well organized and very good at communicating the progress of the project. They also did a great job at explaining the operation of the new systems and were keen to insure that we understood how to operate everything. In addition they were all very respectful of our home and took care to clean as the job progressed. From the office staff through to the service staff everyone involved with our project was professional, very well spoken and attentive to our concerns along the way. We are very happy with the finished product and would recommend Key HVAC without reservation.

Matt B was very professional with his install of my Mitsubishi Split AC. Worked with me on location of both units and kept wiring and piping out of view in living area and up and out of the way in the basement. Matt offered but I didn't really need operational instructions since I had a 3 year old unit in my previous home. He was friendly and easy to deal with. He also completed the project in a timely manner, and did a good job with cleanup when done. I would recommend him and Key to anyone looking for a residential HVAC job. Jim M.

I have been in the HVAC industry for 24 years and with Key for 10. The technology gets better and better and I enjoy getting to work with those improvements. I love to camp with my wife and 3 year old daughter when not at work. I am a Huge Pats fan!

After getting estimates to install a central AC unit to our existing hot air system and installation of 4 Mitsubishi Hyper Heat cold climate heat pump units to our apartment units we selected Key HV/AC based on their presentation and solid estimate. A date was set for the install to begin and the crew showed as scheduled with all the units and equipment to begin and complete our job. At the end of each day the crew cleaned up and gave us an update on the installation progress. There were some issues with the install due to our structure and the crew worked it out and got the job done as outlined. The wall units look great and really do the job! We were very impressed on how well the crew worked together doing the work. There were no added costs and the job was completed to our satisfaction. It was a pleasure to work with a vendor that stood by their estimate. Again, I have to say how good the install crew were. We highly recommend Key for your heating and AC needs. Thank you Jon

Very happy with the mini split heat pump unit that was installed by Key. Garrett was very helpful in getting the units that we needed and Bob did a great job during the installation. The subcontracted electrician ran into some delays and communication with respect to that could have been improved but overall very happy with our new system.

This was a great Team to work with. Garrett was on time for the assessment, sent the estimate the same day and followed up to see if I had any questions. This built my confidence in the company and was the deciding factor in choosing Key over the other companies I contacted. Julie did her best to get me the earliest possible date for the installation. Bob Welch did the installation and he was courteous, professional and very skilled in doing the work. Bob took the time and care that was as if he was working on his own home. I very highly recommend this company. I will certainly use them again for any heating or a/c needs I have in the future.

Key Heating recently installed a radiant floor heating system at my house. What a pleasant experience it was to work with Bob! Bob was courteous, knowledgeable and very competent. I had some questions along the way that Bob was great about answering. It is evident to me from working with Bob and the others at Key, that customer satisfaction is a priority at Key Heating. My radiant heating system works great. I would highly recommend Key Heating if you are considering upgrading your HVAC system or looking into a new one.
