Bryant 348 Expansion Valve
An air conditioning system cannot possibly cool the house if the expansion valve was broken. Your HVAC system expansion valve allows the coolant to expand into its normal low-pressure vapor form from a liquid.
What are some indications that my main expansion valve is almost going bad?
- The air conditioned flow is much warmer than it ought to be exiting the air handler
- The cooling system takes a long time to properly keep things cool
