I live in an apartment and I've noticed that my AC hasn't been cooling well recently. The maintenance staff checked the freon level and said it's fine, but it's still not cooling well.
Tonight I decided to poke around inside the air handling unit to see what I could find. Inside is two sets of cooling coils arranged in an upside V arrangement. When I placed my hand on them while the AC was running I discoverd that one side of the V was was cold but the other set was not. It was at the ambient air temp and was not cooling at all.
My AC is a standard heatpump unit setup with one twist. The hotwater heater is attached to air handling unit via two hoses to provide backup heat (or primary heat if you prefer to heat with gas rather than electricity).
My question is should both sets of cooling coils be cooling or is one set of coils for AC and the other set for heating? Is the reason my AC isn't cooling very well because 50% of the cooling coils aren't working?
Thanks for you help.
