Local Insight — Charleston

Charleston's long cooling season means systems in places like Mount Pleasant, Ladson, Moncks Corner, and Daniel Island often run hard for much of the year. High humidity can also contribute to condensate issues, microbial growth around damp components, and musty smells if maintenance is skipped. Coastal and marsh-adjacent properties may see faster outdoor buildup from salt, sand, pollen, and debris.

Homeowner Tip

Check your air filter monthly during heavy-use seasons and replace it when it looks dirty or airflow drops. Also keep plants, leaves, and debris cleared away from the outdoor unit.

⚠ Do not open sealed panels or try to clean electrical or refrigerant components yourself if you are not trained to service HVAC equipment.
