I have been happy with the work of Calvey Heating and Air since day one. About 8 months after our central heating and air system was installed, Joe came by to make sure everything was working as well as the day he installed it. Everything was performing well, but at no cost at all Joe decided to up the size of the duct from my return to quiet the performance down a bit, as well as increase the airflow. This is something I would have never even thought of, and I appreciate him taking the time and care to do this for my wife and I. Joe is wonderful at keeping the customer happy, and for this I would give him 6 stars if I could!
