HVAC Repair Mansfield TX | Call FreshAir AC

Improper sizing is a leading cause of discomfort and high energy bills here. Our installation process begins with a detailed Manual J load calculation, which factors in your home's specific square footage, insulation, window placement, and Mansfield's climate. This ensures we install a system with the precise capacity to heat and cool your home efficiently, eliminating hot/cold spots and preventing the short-cycling that wears out an oversized unit.

A faulty reversing valve, a common issue in our area, often shows as the system blowing cool air in heat mode or warm air in cool mode, or it may get stuck in one mode. Our expert technicians will perform a thorough diagnosis, checking pressure, electrical signals, and the valve itself. We then provide a clear, upfront repair plan, which may involve cleaning, replacing the solenoid coil, or installing a new valve to restore your system's proper function for both seasons.

Absolutely. While maintenance can't fix an already improperly sized system, our comprehensive maintenance visits are crucial for prevention. We clean coils, check refrigerant levels, and ensure all electrical components—including those controlling the reversing valve—are in top shape. This proactive care helps your properly sized system run at peak efficiency, reduces strain on critical parts like the valve, and helps us spot minor issues before they become major, costly repairs.
