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.

Great service. Keith didn't just replace the part, he even explained to me how my furnace works.

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 earned two degrees and am currently working on my HVAC certification. I enjoy this field because I am never in the same place and am always meeting new people. I enjoy football, surfing & relaxing when I am not at work. I am new to Key and looking forward to a long rewarding HVAC career.

Key Heating and Air Conditioning were absolutely fantastic! The people we were in contact with were Garrett -sales rep, Julie - office, and Mike and Jason Installers. My husband and I were very pleased with everyone's professionalism, knowledge, and promptness when a problem came up. At first, our new unit was not working properly. Mike worked above and beyond to find the problem and fixed immediately. It was not an easy task. But with his diligence and perseverance, he was able to make it happen.

I called 6 different HVAC companies and 4 returned my calls within a day and scheduled times to come to my house and give me a quote. (2) were roughly around $10,000, (1) was $5,900 and Key was $4,200 for THE EXACT SAME UNIT that I had already researched and wanted. Everyone I dealt with was professional and courteous from the office staff to the workers who came to my house. They did exactly what they said they would and on time. I highly recommend Key Heating & Air Conditioning.

They did a phenomenal job at our house. This is the third house that we've used them for in the last 10 years, and their service is second to none. This particular installation was the toughest of all, and they work relentlessly to get it right. I'm very impressed at how conscientious the installers were. They were not satisfied until everything ran perfectly. Just doesn't get better than that.
