Carrier 58STA04510012 Expansion Valve
The AC for your home can not run without the valve working properly. Expansion valves are used in AC systems and allows the refrigerant to expand into its normal low-pressure vaporous form from a high pressure liquid state.
What to see if the main expansion valve is in need of a replacement?
- Your AC takes forever in its bid to cool your home
- The cold airflow is not as cold as it used to be exiting the air handler

If you decide on picking up or ordering do your best and cross-check the model number and also make a visual comparison in order to be sure the correct replacement expansion valve is the one being purchased. There is no rule that says you have to install it yourself. Hire someone with experience in your community to pay to install it for you.
