What is the air temperature rise off the condenser?
Perhaps it could use more of a heatload on the indoor evaporator coil.

This situation is rather normal. Check the
condenser's temp rise anyway, and the indoor temp drop between the
supply air diffusers and the return air grilles.
Do you have apparent good airflow from the diffusers in all rooms?
These three things may, or may not, reveal any helpful information.

Thanks everyone for the answers...


When you check the
temps, you just use a normal thermometer or something?

Yes, use a normal thermometer.

What are you looking for in the inlet and outlet air temps?


The indoor temp/split will vary according to the relative humidity
level. (See chart) Figure A18-1

A lot of factors enter into the indoor temp/split, that is why the
condenser split is helpful information as to the Btu/hr heatload that
the evaporator is transferring to the condenser.
Your outdoor split will not be as much as the condenser chart shows;
note that the higher the relative humidity the higher the condenser temp
rise.
Figure A17-4 Sorry I wrote all over the charts, it's a bad habit of mine.
Do the same simple checks on your upstairs system, and see how they
compare. (Post the temps here.) - udarrell
