Evans R Larry Heating & Air Conditioning - North Charleston's Certified HVAC Services

Salt air is a common issue here. We recommend scheduling annual preventative maintenance where our technicians will clean the condenser coils, check for early signs of corrosion, and can apply a protective coil coating. Keeping the unit clean and ensuring proper drainage also helps significantly extend its lifespan against our coastal environment.

This is a frequent issue during our Charleston summers. Common causes include low refrigerant levels due to a leak, a dirty or frozen evaporator coil, a failing compressor, or restricted airflow from a clogged filter. Our technicians are experts at diagnosing the root cause quickly—whether it's a repair or a needed part replacement—to restore your cooling without delay.

First, check your thermostat settings to ensure it's set to 'cool' and the temperature is lower than the room temp. Next, replace your air filter if it's dirty, as a clogged filter is a common culprit for reduced airflow and cooling. If that doesn't help, turn the system off and call us. Continuing to run a struggling unit can cause further damage.
