I was last here a year ago with this thread.
Now for the first time since installation of that system we are having a bona fide heat wave. It has been 100 to 110 degrees here for the past eight days straight with dewpoints in the 60s and 70s and overnight "lows" in the 80s.
I have seen my indoor temperatures slip to 77, 78 and 79 a lot as it struggles to keep it below 80. Sometimes it fails and one day it was 82 in here for a time. It is controlling the humidity though keeping it high 40s and through the 50s.
I decided to check the db temp of my supply air just for the heck of it. It is high 50s from about 2am to Noon but then it starts slipping through the 60s to finally hold about 69 or 70 through the hottest part of the day.
One day though (and I have noticed this before but thought it was just my imagination probably) it seemed like the air wasn't as cool to me so I checked and it was sitting at 80 I don't think that 80 degree supply air can do a whole lot of good. It was there for five or ten minutes and then it came back to 69. Meanwhile though the house got two degrees warmer and it was of course unable to recover that until hours later.
My question is it that normal? Or is there something wrong?
