HVAC Repair Lewisville TX | Call A Affordable Ac & Heat

Yes, a refrigerant leak is a common issue in our area that significantly reduces cooling capacity. At A Affordable Ac & Heat, we start with a precise leak detection test. Once located, we repair the leak, evacuate the system, and recharge it with the exact manufacturer-specified amount of refrigerant. This repair restores your system's efficiency and cooling power, helping you beat the Texas heat effectively and affordably.

Our preventative maintenance is designed specifically for local systems. We perform a thorough 20+ point check, which includes inspecting and tightening all electrical connections, testing thermostat wiring and calibration, checking refrigerant levels to spot early leaks, and cleaning critical components. This proactive service helps prevent unexpected breakdowns from wiring issues and loss of cooling, saving you money and ensuring reliable comfort throughout the year.

Most thermostat wiring problems can be repaired without needing a full system replacement. Our expert technicians will diagnose the specific wiring fault—whether at the thermostat, in the wall, or at the HVAC unit. We then repair or replace the damaged wiring to restore proper communication and control. We only recommend replacement if your system is very old, inefficient, and has recurring major issues, always providing you with transparent, cost-effective options first.
