What the TXV Does in Your AC System
The thermostatic expansion valve (TXV) meters the precise amount of liquid refrigerant entering the evaporator coil. It's a critical component for efficient cooling — too much refrigerant floods the coil and risks compressor damage; too little starves the coil and reduces cooling capacity. When a TXV fails, it typically sticks in one position — either flooding or starving the evaporator — causing symptoms like poor cooling, ice formation, high head pressure, or compressor overheating.
A Difficult Diagnosis Done Right
TXV problems are notoriously tricky to diagnose because the symptoms mimic other refrigerant system issues. Low superheat could be a TXV problem or an overcharge. High superheat could be a TXV problem or a low charge from a refrigerant leak. Our technicians use superheat and subcooling measurements, along with temperature differential readings and pressure analysis, to isolate the TXV as the specific failure point before recommending replacement.
Precision Replacement Work
TXV replacement involves recovering refrigerant, removing the failed valve, brazing in the new valve (matched to your system's tonnage and refrigerant type), replacing the filter-drier, evacuating the system with a vacuum pump, and recharging to manufacturer specifications. It's detailed work that requires proper tools and training — the kind of AC repair that Quality Comfort handles expertly for homeowners across Asheville and Western NC.
HVAC Challenges in Fletcher
Fletcher's location along the I-26 corridor brings steady development with new homes and commercial properties that need properly designed HVAC systems. The area near the Asheville Regional Airport has more commercial HVAC demand than surrounding residential communities. Fletcher's mix of 1990s-era subdivisions and new construction means many homeowners are facing their first major system replacement.
Seasonal Tip for Fletcher Homeowners
If you're in a Fletcher home built in the 1990s–2000s, your original HVAC system is likely at or past its expected lifespan. R-22 refrigerant (used in systems installed before 2010) is no longer manufactured — if your system still uses R-22, now is the time to plan a replacement before your next breakdown becomes an emergency.
