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.

Field technicians are excellent. Courteous, thorough, obviously familiar with equipment and know what they are doing. 5 stars! Pricing seems reasonable. Unfortunately, the scheduling, communication and follow through on appointments is very unreliable. Recent appointment was three reschedules....2 at last few hours - and one after a no show. Email communications are late (several days after appointment). Office seems to struggle with technology....How about texting regarding service changes? Each of those 3 times I rearranged my work day to be home...so it ends up being costly I struggle with giving a combined rating...I would say technicians 5 and service/scheduling/communication 2... Bring that end of the business up to par and I would say 5 star

Albert was resourceful and communicated with a positive professional attitude. Not only is he a Veteran United States Army Ranger, but incredibly proud of this great nation. Thank you for sending him as our service rep.

By Lisa C. on 01/16/19
Our technician was wonderful. Very efficient and informative. I would highly recommend him and this company. Thank you Albert!

By Shirley & Steve C. on 01/14/19
Here is the issue... Keith is knowledgeable, BUT after months of visits and $1000's we are still exactly where we started out. Nothing has improved. I get the feeling Key is just replacing stuff HOPING that it will fix the problem.. and meanwhile they keep charging us!!

By Dick & Snooky R. on 01/14/19
albert was great.very please with him. thankyou dick

By Erik W. on 01/13/19
Keith is without a doubt the best and most knowledgeable service technician that I have ever dealt with. I would highly recommend him to anybody.

By Jan & Rick K. on 01/13/19
After some back and forth with two other outfits, Key diagnosed the problem and, after getting the parts, quickly fixed the situation.

By Mal & Elanie L. on 01/12/19
Aaron was friendly, prompt, courteous and helpful. He explained improper placement of filter clearly.

By Stephanie H. on 01/06/19
Very happy with the service we received from Key. Everyone we spoke to was friendly and helpful. Albert was very professional, polite, and fixed all issues we mentioned, including providing an explanation as to what he did. We will certainly be using Key again!

I served in the United States Marine Corps for five years. I enjoy anything mechanical. I really enjoy being an HVAC tech. Everyday I am learning something new and adding to my HVAC knowledge base. Outside of work I enjoy spending time camping with friends, daughter and and a baby on the way!

Excellent service all around. Colin was very responsive and helpful on the phone. Richard arrived on-site within two hours of my initial call, and was extremely courteous and professional while diagnosing the no heat/no hot water problem. Richard returned the next morning to replace failed components and restore service. I've had nothing but great experiences during the past 10+ years as a Key Heating customer.

Key heating has been responsive, fair, and easy to work with. I've worked with their repair department and sales department. Richard is knowlegable, to the point, and efficient. Colin although very busy has been able to schedule repair and install without issues and when questions arose was able to get answers. Alex provided a very fair quote and the product was delivered as quote. The office staff who answers phones is friendly and helpful. I won't hesitate to keep using Key.

I recently needed service on my Mitsubishi Slim Heat Pump . Key HVAC was the original installer. They were able to quickly set up an appointment for a non-emergency situation. The field technician (Richard Chagron) was very thorough in diagnosing the problem and getting my machine back in working order. He took the time to explain what had happened with the unit. I was very pleased with the service rendered and the price charged. I chose Key HVAC five years ago to install the Mitsubishi systems in my house. In total, I had quotes from five contractors. I do not normally choose a vendor strictly on lowest price. Key had the best solutions for my house and as it turned out, the best pricing. Their personnel are very knowledgeable and very professional. I highly recommend them for a new installation or for maintenance.

The team at Key was great. They fit the appointment to work with our schedule. They arrived when they said they would. They were professional, courteous and helpful. The technician knew about our equipment, serviced it in a timely way, and discussed long-term options as our equipment becomes older. We'd certainly use Key again in the future for our heating and air conditioning needs!

When I contacted Key HVAC just before the 4th of July holiday I was assuming it was going to take me about a month to schedule an appointment. To my surprise they person I spoke with on the phone said they could send someone the following week. Richard arrived and diagnosed the problem, he called me at work and discussed some options with me and we decided to go with his recommendation. He called me again when his work was complete and gave me some instructions for the next few weeks. He was very pleasant and professional. Richard explained everything in a way I could understand. Thank you for that. I will have to follow up in a week to check in on the status of the cooling system. I am very pleased with this service and would definatley call again and reccommend their services. Thank you

overpriced. Did not bring a filter, so used one of mine. Found out later that there are things that should have been done that weren't.

By Mary Jane B. on 05/17/17
Richard did an excellent job and answered all my questions and advised a/c settings to stay cool at night.

Outstanding employees. Installation of central A/C in an older home was a challenge but Richard was able to accomplish the installation with a smile on his face until the end.
