Apparently where I left (winfield) is a lot worse. The project manager of this community told me when they built in Winfield, people had $1500 water bills. OUCH!
Lately we've had some mid 90 degree days here in CO, and next couple of weeks high 90s for awhile. Obviously no humidity but our AC takes FOREVER when it's hot. We have a tri-level 2,400 sq ft townhome so turning off and on the AC doesn't work well here.
Like others it can take many hours just to drop the house from 78 down to 74. Our HVAC guy actually told us the lack of humidity here is hard on AC units and they function better and cool better in higher humidity. I have no idea if that's true but being a tri-level house with no shade kills us in the afternoons. AC unit is only 2 years old.

Also true.
Majority of the energy removed from the air is from the latent heat of condensation, or the energy removed in the process of condensing a gas to a liquid. Think of the opposite state change (liquid to gas) a pot of water gets hot very quickly but stalls out as it approaches boiling point. It takes a massive amount more energy to vaporize that water than it does to change the sensible heat(temperature)
When you have so little moisture content in the air it's very difficult to drop the temperature when you can only get your evaporator to 37-45* before it starts to freeze.
This is also why it takes a long time to bring a house down in temperature on first time operating cooling. All the moisture needs to be removed from the air before the sensible temperature begins to drop further
When I had my yard resodded last year the village actually called me and asked if I had toilets with bad valves or something that were running all the time because of the drastic change in bill...
Water bill sucked but the lawn looked great.
I would assume at 3800 square feet you have 2 units. One for up and downstairs. (If you don't I cannot even imagine the size of that thing outside or the price of it)
You are a smart person so I'm sure you already know that's a monster house to cool and will take longer to cool down vs a 1500 square foot home.
I would say high 80s is normal for our summer couples with some weeks in the 90s. I don't find that my unit was struggling. I mean it would run a lot longer on those 93...94 days lately. But the temp never went up.
Seeing as your home is more high end did you look into seeing if you have a 2 stage ac system? Comes on low and ramps up as needed?
Time to mock them like they did when we were in the low 20s and they were all excited about 70 degrees.
then it says "today is forecasted to be COOLER than yesterday".
Pretty much the same at our house with similar specs. I only let it get to 76 when we're not home and 72 when we're home.
At least it generally gets much cooler out once the sun starts to go down.
