Mitsubishi MSH-12NV Expansion Valve
Any home AC unit would be impossible to cool the home if the valve was not functioning. A normal AC expansion valve allows the coolant to expand back into its natural vapor state from its highly pressured liquid form.
Red flags of a deteriorating main expansion valve
- The air conditioned flow is not as cold as it really should be coming from the vents
- The air conditioner takes a really long time in its effort to bring down the temperature

If you are unsure about the installation of the expansion valve by yourself then it is probably best to find a professional in your area to do the work for you.
