I first heard about Complete Comfort Heating and Cooling when they installed a geothermal system at my previous home. That was 20 years ago. Now, they service the geothermal system at my current home. I could not be happier with them! They have consistently good service, and they are courteous and knowledgeable people. Most recently, they had to come out and replace a part on the heating system for me. They communicated well, and I had no complaints about the service!
