Sawyer's Electrical Heating & Air Conditioning | Certified HVAC Services in Mullins, SC

Yes, a faulty reversing valve is a common culprit, especially with our local systems working hard year-round. This valve is crucial for switching your heat pump between heating and cooling. If it's stuck or failing, you'll lose one function entirely. Our technicians can diagnose this quickly, check related electrical components, and perform an honest repair to get your comfortable heat restored.

Uneven cooling is a frequent issue we see in local homes and is often due to airflow imbalances or ductwork problems. It could be blocked vents, leaky or poorly insulated ducts in the attic or crawlspace, or an undersized system struggling to reach all areas. We perform comprehensive evaluations to pinpoint the cause—whether it's a simple duct adjustment, a zoning solution, or a system performance issue—and provide a clear fix.

Given our hot, humid summers and variable winters, biannual maintenance is key. Before summer, we focus on cleaning coils, checking refrigerant levels, and ensuring your AC can handle the heat. Before winter, we test the heat pump's reversing valve operation, check defrost cycles, and inspect heat strips. This proactive care from your local experts at Sawyer's helps prevent major breakdowns and keeps your system running efficiently, saving you money and discomfort.
