Carrier 48GS Expansion Valve
Your HVAC system expansion valve allows the refrigerant to expand into its normal low-pressure gas state from its highly pressured liquid form. An AC can not deliver properly cooled air if the expansion valve was totally worn out.
Simple signals the AC expansion valve should be replaced
- Cooled air is not as cold as it really should be streaming from the vents
- Your AC takes its sweet time to comfortably cool your home
