Penders Heating & AC Service: Local HVAC Repair Serving Charleston, SC 29407

Short cycling is a common issue here, often caused by an oversized unit, a dirty air filter, or refrigerant problems. It strains your system and increases humidity. Our technicians can diagnose the exact cause—like checking for proper airflow in your attic or crawlspace—and perform the necessary repair or adjustment to restore normal operation and efficiency.

Signs include uneven heating/cooling between rooms, higher-than-normal energy bills, and excessive dust. In our older Charleston homes, ducts in attics or crawlspaces can develop leaks or become disconnected. We perform thorough duct inspections and sealing services to stop conditioned air from escaping, which improves comfort and can significantly lower your cooling costs, especially during our hot summers.

Bi-annual preventative maintenance is crucial. Before summer, we clean coils, check refrigerant levels, and ensure your system can handle the heat and humidity. Before winter, we inspect heat exchangers and electrical components. This proactive care helps prevent sudden breakdowns, improves efficiency, and directly addresses local issues like short cycling by keeping your entire system in optimal condition.
