Carrier 48DD Expansion Valve
Every air conditioning system contains an expansion valve that allows the coolant to expand into its regular gaseous form from a liquid. An air conditioner could not work without a properly functioning valve.
What are the clues to watch out for to know my Carrier expansion valve is not working right?
- The cooling system takes too long to bring down the temp in the house
- The cold airflow is well below the temp it ought to be blowing from the vents
