Mixson Heating & Air Conditioning | Emergency HVAC Services in Hollywood, SC

This is called short cycling, a common issue here that strains your system and increases bills. Often caused by an oversized unit, refrigerant issues, or a faulty thermostat, it requires expert diagnosis. We'll pinpoint the exact cause—checking pressures, sensors, and airflow—and perform the precise repair to restore normal operation and protect your equipment from premature wear.

A malfunctioning reversing valve is a likely culprit when your heat pump gets 'stuck' in one mode. This valve directs refrigerant flow for heating or cooling. We'll test the valve's solenoid, check for refrigerant issues or debris, and determine if a repair or replacement is needed to restore your system's full functionality, ensuring you have reliable comfort in every season.

Our local climate puts extra stress on HVAC systems. Our preventative maintenance includes cleaning coils, checking refrigerant levels, calibrating thermostats, and inspecting electrical components. This proactive service catches small issues—like those that lead to short cycling or valve problems—before they become major repairs, improving efficiency, extending your system's life, and preventing unexpected breakdowns.
