Delonghi PACC100 Expansion Valve
The AC in an HVAC system would most likely give you heated air if it were to lack a properly working expansion valve. Pretty much every air conditioning system has an expansion valve that allows the refrigerant to expand back into its natural gaseous form from its highly pressured liquid form.
Key signs of a declining refrigerant expansion valve
- The air conditioned air is not as cool as it used to be coming from the vents
- AC unit takes its sweet time to comfortably keep the house cool
