Desa B115 Expansion Valve
Your HVAC system expansion valve makes it easier for the refrigerant to expand back into gas state from its highly pressured liquid form. Your home air conditioner could not emit cold air if the expansion valve was either damaged or just not working properly.
Red flags the AC expansion valve should be replaced
- The cooled air is not as cold as you are accustomed to for the AC to cool the house
- The air conditioner takes way too long in its bid to cool
