Danby DPAC10011 Expansion Valve
A split-system AC unit can not run if the valve was not doing its job. Your HVAC system expansion valve allows the refrigerant to expand back into gas form from a high pressure liquid state.
What red flags are there that my main expansion valve is about to stop working?
- The air is warmer than you are accustomed to as it comes from the air conditioning unit
- AC unit takes a really long time to comfortably keep things cool
