I have been using Complete Comfort Heating and Cooling for about four years now, and they are always professional, they listen to any and all of my concerns, and they take care of things. Michael was the tech who last came out, and he was on time, polite, he was very efficient, and he knew his job well. He replaced the filter and did a seasonal check of our system. Also, their office staff is awesome! They answer my call quickly and always know what's going on. Plus, if they're not sure of a particular issue they will call me right back. They do a great job and I will absolutely continue with their services.
