Carrier 52F Expansion Valve
Your HVAC system expansion valve allows the coolant to expand into its normal low-pressure vapor state from its highly pressured liquid form. Your AC can not supply your house with cold air if the expansion valve was worn out.
How do you know if your main expansion valve is almost going bad?
- The air conditioner takes a really long time in its bid to bring down the temperature
- The air conditioned flow is not as cool as it ought to be blowing through the ductwork
