International Comfort Products PGMD48G0904 Expansion Valve
Any home AC unit can not run if the expansion valve was broken. An expansion valve permits the refrigerant to expand back into its natural gaseous form from a high-pressure liquid form.
What signals that my main expansion valve is in need of replacing?
- Air flow is not as cool as than the usual air as it comes from the air conditioning unit
- AC unit takes a long time in attempting to bring down the temperature
