Carrier 48XZN036090300 Expansion Valve
An air conditioning system cannot possibly cool the house if the valve was missing. Your HVAC system expansion valve permits the refrigerant to expand back into vapor form from a high pressure liquid state.
Subtle hints the expansion valve is in need of replacing
- The cold airflow is definitely not as cold as you are accustomed to so as to feel comfortable in the house
- The outdoor AC unit takes too long to comfortably cool the indoors
