Carrier 58MXA100 Expansion Valve
Pretty much every air conditioning system has an expansion valve that lets the coolant to expand back to its low-pressure vaporous form from a liquid. An AC system would probably blow heated air if the valve was not doing its job.

- The air conditioner takes a really long time in a bid to cool
