Delonghi PACC120 Expansion Valve
Your home AC system contains an expansion valve that makes it easier for the refrigerant to spread back into gas form from a liquid. An AC could not run without a working expansion valve.
What to see if the expansion valve is almost going bad?
- Cold air is not as cool as than the usual air coming into the home
- Your AC takes way too long in attempting to keep the temperature down
