I've read the rules, and I'm not a HVAC tech.... but I'm going to go out on a limb and ask because I don't think this question crosses the "I'm not giving out free advice" line. Not looking for advice, or troubleshooting, or any "how-to's"
I just purchased and installed a Nest thermostat. My previous thermostat... set it, forget it... end of discussion. Now, I've got all this data reporting about my energy use and the ability to check my unit at work and on the road, how long it takes to heat and cool, etc.
Now that I've got all this information at my finger tips, one thing that really stands out. That being how poorly my unit does at cooling.... I think. This summer has been HOT, yesterday was 100.
Yesterday I had the AC off for a while, inside temp got up to 88. I turned the AC on at 5:30 and at 10:00 when I went to bed, it was still running with a temp of 74. At night, the thermostat goes up to 78, at 5:15 it is set to go to 72. When I left the house at 6:30 the temperature was 75.
My home is about 2,400 sq ft... with 9' ceilings... with a lot of windows. Its a new construction home in 2008... built by a "kit" home builder.. so I'm pretty sure they cheaped out on my HVAC system.
So my question is, with temps doing a Riverdance on the 100 mark, is taking 4:30 to drop the temp 14 degrees BAD, or for that matter, 1:15 to drop 3 degrees BAD? I'm just not certain if I have a problem with my system, if its just simply under powered, or I'm just not being realistic with my expectations.
