Your AC isn't cooling right? It could be more than just low refrigerant. 🔧
This system had a faulty thermal expansion valve (TXV) — the part responsible for metering refrigerant flow into the coil. When it fails, your whole system struggles to keep up, no matter how much you crank the thermostat.
Here's what proper repair actually looks like:
✅ Faulty TXV removed and new unit installed
✅ Filter dryer replaced
✅ Pressure tested at 396 PSI with soap bubble leak detection
✅ System recharged and verified
End result: stable pressures and a clean 15° superheat reading — meaning the system is metering refrigerant exactly the way it should.
Skipping these steps is how "quick fixes" turn into repeat service calls. We don't cut corners on diagnostics or testing — because your comfort (and your wallet) depend on it getting done right the first time.
