The Configuration you describe is not valid. For instance if the air off the
coil was 12 C with 50% bypass at 26 C the mixed air temp would be 19 C.
In addition a hot water coil could not be used by a reverse cycle heat
pump. So there is probably either a third coil or a damper
to shut off the air flow to one side of the coil

A question for the pros --

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 ho****er
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.
