Heat Controller B-VMH09FC-1 Expansion Valve
Your HVAC system expansion valve permits the refrigerant to expand into its normal low-pressure gas form from a liquid. The AC in a split system could not run if it was deprived of a functioning expansion valve.
Signs of a defective expansion valve
- The outdoor AC unit takes forever to cool as it should
- The cooled air is not as cold as it ought to be coming into the home
