I had to replace my central air outside condenser unit and inside coil. I interviewed several company and got price quotes from them. ComfortMaster was not the cheapest, but I felt the most comfortable with their approach. On the day of installation, a team of three installers came and did a wonderful job installing and testing the unit. Their manager stopped couple of time to make sure everything was done right. In the past couple of years, I had to deal with couple of HVAC contractors whose quality of work and attitude were terrible. I am pleased to have found a company who know its business and truly take its customer service seriously.
