Haier HR18D2VAR Expansion Valve
Almost all AC systems have an expansion valve that allows the coolant to spread back into vaporous form from a liquid. An air conditioning system would produce no cooled air if the valve was not present
Important signs that your Haier expansion valve needs to be replaced
- The air conditioned air is much warmer than it used to be coming from the AC
- The air conditioner takes way too long in attempting to keep the temperature down
