Carrier 50GS042300 Expansion Valve
Expansion valves are used in AC systems and permits the refrigerant to expand back to its low-pressure gas state from a liquid. An air conditioning system would not yield any cooled air if the expansion valve was somehow damaged.
Major symptoms that your Carrier expansion valve should need replacing
- The cold airflow is much warmer than you are accustomed to coming from the air handler
- The air conditioner takes a long time trying to keep the home at a comfortably cold temperature
