What are the common signs of a bad TXV?

Warm vents, frost on the evaporator or lines, suction pressure stuck high or low versus expected, and unstable high-side pressure even with condenser fans on high.

Do you always replace the dryer/accumulator?

Yes. If the system is opened, we replace the receiver/drier or accumulator to protect the new metering device and ensure proper moisture control.

How do you confirm a TXV fault?

We check subcooling and superheat, inspect the metering path, command condenser fans, and verify refrigerant charge by weight. If metering is restricted or stuck, we replace the TXV.

Can you service both R-134a and R-1234yf?

Yes. We carry both refrigerants and charge to the exact factory weight after repairs.

Do you offer mobile service across Miami-Dade?

Yes—mobile diagnostics and repair across Hialeah, Doral, Miami Lakes, Miami Beach, and nearby areas.
