Our 17-year old top-of-the-line air conditioning quit and the house was not only hot but sweaty humid! We called Cliff's because they were not too far away. John came to the house that same day and diagnosed a bad compressor that used the old refrigerant -- best/only solution: a new heat pump and a new (matching) air handler. We got bids from Cliff's and three other HVAC outfits in our area. Cliff's had the best prices and could do the work in just a few days. It was a no-brainer to go with them. The install of new equipment took less than a day, the techs were knowledgeable and polite, and the system has been running great for the last three weeks. We are happy to give them "five stars!"

I called Cliff’s due to a problem with our heat pump this past summer. The office staff was courteous and professional. The Technician arrived within a two hour window and took care of the issue. He is a professional and knowledgeable employee who took the time to explain the problem with my unit and answer my questions. Cliff’s is definitely a 5 star locally owned and managed company.

I've had 3 complete systems done by Cliffs. They have updated out HVAC systems in our house during a remodel and did an excellent job. They also did a system on a detached garage we had built. Great service and quality. Highly recommended
