My AC when it's 90 out will nearly run continuously. I'm just curious
if that is normal or if I have been undersized by the contractor
(installed a year ago).

I live in Colorado - dry climate.
We get a lot of direct sun.
The ranch has 1800 sq ft on the main level and a below grade bsmt of
the same size. Part of bsmt is finished, but we do not occupy it
often.

Mid June - end of August can have 90 degree days; seems like most days
are 85-95.

We set the thermo at 76 degrees. But if it's 90 outside and I try to
set below 76, it will never make it down until evening. (That is okay!)

For mid 80s days, it's fine (remember we set our thermo at 76 though).

I'm concerned that a) the HVAC contractor has undersized my AC unit
and b) if a new owner preferred 72, it could not be held during our
summers.

I realize it's best not to oversize the unit, but with a dry climate
to begin with, removing humidity is not much of an issue.
Thanks,


Why would they want to set the TH at 72? As the temperature goes down
the relative humidity tends to edge upward; i.e., cold and clammy.
If you provide adequate air circulation in that dry climate you should
be very comfortable at 77 to 79-F.
It appears to be sized right. What tonnage is it.
Check out the Human Comfort Zone. They can add room A/Cs if they want
to freeze and pay the costly utility bill.

Boy, you are a piece of work, udarrell -
Telling the whole world what temperature they are comfortable with.

My brother-in-law just might accept 68 degrees on the high side but
he usually likes it lower. Ever hear the terms about satisfying the
customer or what the customer wants or the customer is always right?
