We have been using Summit Heating & Air Conditioning for almost two years now, ever since we moved into our home. We have had two different service techs come by to do work and maintenance on our system, and they have both been great. Our most recent experience though was a bit disappointing. We thought there was a problem with our system, and paid the $80 service fee for the guy to look at it and say it actually wasn't a problem with the system. It wasn't their fault, and we didn't know going in that the issue wasn't due to the system. Despite this, they have been great, and we will absolutely use them again.
