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?



I didn't think he was dictating thermostat settings, but questioning
the logic. It's a question of the system design. When a system is
specified design temperatures and humidities are provided. Someone who
wants 68 degrees is asking a system to perform outside its design
criteria. R


I just discovered that he has a 3-ton outdoor and indoor air handler and
coil system.
If you are cooling and additional 1800-sq. ft. of basement that changes
the equation!
Have your home checked and see what cooling Btu/hr it calls for; some
utility companies will do it for you!

Yes, Colorado is Very Dry! Design at Durango Design is 87-db and 59-wb
that charts to only around 20% RH.
Denver at the high altitude is worse: Design is 91-db and 59-wb; it's
literally off the charts.

A well insulated 1800-sq. ft. Ranch style home in that dry a climate
ought to be easily handled by a 3-ton system.
Here in a rather comparatively humid SW WI (Madison 88-db and 73-wb for
a 49% RH) we have 2400-sq. ft homes being nicely handled by 2-ton systems.

How good are the techs that check your system?
I believe there might be room for improvement; that merely an educated
opinion as I don''t have any of the required relevant facts.
Everything might be okay! During the hottest days it should run most of
the time.
