Nordyne M3RL-080A-BW Expansion Valve
A split-system AC unit can not work right with no functioning valve. Your HVAC system expansion valve permits the refrigerant to expand back into its natural vapor form from its highly pressured liquid form.
What are the clues to watch out for to know my main expansion valve is almost going bad?
- Your AC unit takes forever to actually cool
- The air conditioned air is not as cool as it ought to be exiting the vents
