HVAC Repair Chapel Hill NC | Call Heating and Air Conditioning Service Now

Our humid climate can lead to condensation inside ductwork, creating an ideal environment for mold. We start with a thorough inspection, then use specialized equipment to clean and disinfect the ducts. More importantly, we identify and fix the underlying moisture source—like inadequate insulation or a malfunctioning AC unit—and may recommend solutions like UV lights or enhanced dehumidification to prevent it from coming back.

Yes, a faulty reversing valve is a common reason for this problem in Chapel Hill's many heat pump systems. This valve switches the refrigerant flow between heating and cooling. Our technicians will diagnose the valve with pressure and electrical tests. If it's stuck or failed, we perform a precise repair or replacement, ensuring your system correctly reverses to provide warm air efficiently throughout our cooler seasons.

We recommend bi-annual maintenance—once in spring for cooling and once in fall for heating. This includes checking refrigerant levels and valve operation on heat pumps, cleaning coils to maintain efficiency and reduce moisture, inspecting drain lines to prevent clogs that cause humidity issues, and ensuring the entire system is sealed properly. This proactive care is the best defense against mold growth and component failures specific to our area.
