Carrier 48GP042090300 Expansion Valve
Every air conditioning system contains an expansion valve that allows the coolant to expand back into gas form from its highly pressured liquid form. Your main AC unit cannot possibly cool the house if it were to lack a properly working expansion valve.
Hints of a deteriorating Carrier expansion valve
- The cool flow of air is well below the temp it really should be blowing through the ductwork
- AC unit takes a really long time in its effort to keep things cool
