American Comfort Heating & Cooling installed my complete heating and air conditioning unit about 10 years ago in my penthouse condominium. This install was well executed, on time and very clean. They have followed up with the annual maintenance of this system for 10 years. When the service technician arrives they always cover their shoes before coming in and really they work very clean. Lewis who was involved with the initial installation is an outstanding technician! I am very happy with their service and yes I have recommended them to others.
