Mitsubishi MSZ-FE12NA-8 Expansion Valve
A normal AC expansion valve lets the coolant to expand back into its natural vaporous form from a high pressure liquid state. An air conditioning system can not work right with no functioning valve.
What are some indications that my main expansion valve is in need of a replacement?
- Air from the AC is not as cool as it really should be so as to feel comfortable in the house
- AC unit takes way too long to comfortably bring down the temperature
