When Should I Replace my AC Receiver Drier?
TechXpert verified by Ken Kontra
Replace your receiver drier when the refrigerant circuit has been opened. The refrigerant filter drier is a disposable component of your AC system that needs to be replaced whenever the circuit has been opened and exposed to moisture and humidity from the outside air.
Reasons for Replacement
The refrigerant filter drier works hard to prevent excess moisture from entering other parts of your AC system. Without it, the performance of your compressor’s lubricating oil may fail and your AC system could corrode. Replacing your refrigerant filter drier can significantly lower the chances of facing these issues.
You should replace your refrigerant filter drier if and when:
You’re replacing the compressor
The circuit has been opened
There’s been a serious leakage in the AC system
There’s excess moisture
Acid has been detected in the system
The filtering and desiccant layers are restricting refrigerant flow
Unusual sounds are coming from the AC system
Nothing Left to Receive
When your AC refrigerant filter drier has run its course, it’s time to retire it. Once your refrigerant filter drier is worn out, it may lead to circuit clogs and problematic operating pressures in your system. The bottom line is that malfunctioning refrigerant filter drier can impact other parts of your AC unit, so you should contact an HVAC technician to help with your drier installation sooner rather than later.
