AC Metering Device Replacement in Spokane, WA
The metering device regulates how much liquid refrigerant enters the evaporator coil, which directly controls how efficiently your system removes heat from your home. A failed or restricted metering device causes the coil to flood with refrigerant, freeze over, or starve and overheat the compressor. There are two main types — fixed orifices and thermostatic expansion valves — and the correct replacement depends on your specific system design. Installing the wrong type creates new problems immediately.

When to Call
When You Need AC Metering Device Replacement
- Your evaporator coil freezes into a solid block of ice during normal operation

- You replaced a coil and the new coil is performing poorly with the original metering device
How It Works
Our Process for AC Metering Device Replacement
- 1
Refrigerant Circuit Analysis
We record suction and discharge pressures, superheat, and subcooling readings to characterize exactly how refrigerant is moving through the system.
- 2
Metering Device Verification
We confirm the metering device is the source of the abnormal readings rather than low charge, a failing compressor, or a restricted filter drier.
- 3
Replacement and Recharge
The system is recovered, the metering device is replaced, and the system is evacuated and recharged to correct specifications.
- 4
Superheat and Subcooling Confirmation
We measure superheat and subcooling after recharge to verify the new metering device is controlling refrigerant flow correctly.
Spokane Context
Why this matters in Spokane
Spokane's dry summer heat puts AC systems under sustained load for weeks at a time. A marginal metering device that holds on in mild weather often fails completely during the first prolonged heat event of the season.
Straight Talk
About pricing & scope
Metering device replacement always involves refrigerant recovery and recharge, which adds to the scope and cost of the repair. If the filter drier is old, we'll recommend replacing it at the same time since opening the system is required either way.
