Air Conditioning Expansion Valve Replacement
Common symptoms
When the expansion valve fails or clogs, the air conditioning system will not blow cold air, or may intermittently blow cold air for very short periods.
Best practices
The air conditioner evaporator or receiver drier may need replacement, and the system may need to be flushed if debris or sludge is noticed.
Common misdiagnoses
The expansion valve is controlled by a temperature sensor, so this sensor is often blamed for failure of the expansion valve.
It maybe necessary to Evacuate and Recharge the Air Conditioning system during this repair. This will be an additional cost that is not reflected in this estimate.
