Carrier 38TKB042 Expansion Valve
The AC in a split system could not emit cold air if the valve was not doing its job. Expansion valves are used in AC systems and allows the coolant to expand back into its natural vapor state from its highly pressured liquid form.
Signals the expansion valve should be replaced
- The air conditioned flow is warmer than it really should be streaming from the vents
- The outdoor AC unit takes a really long time to actually cool your home
