Dyess Heating & Air - Hilton Head Island's Best HVAC Services

This is called short-cycling, a common issue in our coastal climate that strains your system and raises bills. It's often caused by an oversized unit, a refrigerant leak, or a faulty sensor. Our technicians will diagnose the specific cause—whether it's from a previous improper installation or wear and tear—and provide a precise repair to restore normal, efficient operation.

Signs include uneven cooling/heating, unusually high energy bills, excessive noise, and frequent repairs. Poor installation often fails to account for our specific humidity and salt air. Dyess Heating & Air performs comprehensive evaluations, checking ductwork, refrigerant charge, airflow, and thermostat calibration. We'll identify any installation flaws and recommend corrections to optimize your system's performance and durability.

Our Hilton Head-focused inspection is a detailed health check. We examine electrical connections, test system controls, clean coils affected by local pollen and salt, check refrigerant levels, and assess airflow. This proactive service catches small issues—like those leading to short-cycling—before they become major breakdowns, ensuring your system runs reliably through our hottest summers and mild winters.
