Comfortmaster Heating & Cooling Services has always done really good work for me. This was not my first time using their services, I have been using them for a while now. I have stayed with them over the years because their customer service is good, their pricing is fair and their technicians are knowledgeable. They came out recently for the annual service check for my unit and everything turned out fine. The technician arrived between the window of time they set aside for my appointment. He was polite and professional. He did a quick assessment of the unit then explained his findings to me. He took the time to answer the questions I had. I find them to be honest and reliable and I will continue to use Comfortmaster Heating & Cooling Services.
