Qualified HVAC Repair in Rochester Hills, MI 48307 - A & S Unlimited Heating & Cooling

For Rochester Hills residents, a common local HVAC issue is refrigerant leaks. Signs include your AC system blowing warm air, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound from the outdoor unit. Reduced cooling capacity and higher-than-normal energy bills are also indicators. Our technicians are trained to quickly locate and repair these leaks, ensuring your system runs efficiently throughout our Michigan summers.

Our maintenance service is designed to keep your system running smoothly and prevent costly repairs. For furnaces, we check heat exchangers, burners, and safety controls. For AC units, we clean coils, check refrigerant levels, and ensure proper airflow. We also inspect electrical connections, lubricate moving parts, and test the system's overall operation. This proactive care, offered since 1968, helps extend the life of your equipment and maintain its efficiency for your Rochester Hills home.
