I just had a new HVAC system installed in a new house and have not paid for
it yet. Today the temperature is 100 outside. I have my thermostat set
to
77 and the actual temperature is 81. (This is upstairs, downstairs a
separate system is maintaining the selected temperature.)

I am getting about a 20 degree drop. Is that acceptable or should the
system be doing better?

Thanks for any help!

It should be doing better. We had the same problem for years with our unit
and could never get below 80 if it was 100+ outside. Other houses in the
area could reach 70 if they wanted. We eventually sold the house and the
new owner's inspection showed up that the unit was not big enough for the
house. We put some money in escrow for them so the whole thing would just
go away.

BTW, we had for years been trying to get A/C people to find out what was
wrong but we would have been better employing retarded chimps. ALL of them
were useless cretins. Not one of them (7 or 8 different people) said the
unit was too small and it was just fine - but it wasn't.
