From what I know, you get more deformaties when they are too cold...not to hot! Besides, to get males, most people incubate around 90. If anything, I would think they might end up with an unexpected male or two if it's within the first few weeks of incubating.
Tremper actually suggests raising temps to around 90 after 3 weeks to improve the color of albinos.
It's rather rude chastising him for a mistake, and giving him a guilt trip over it. I'm suprised that would come from you WiteLeo...you're usually a great help.
As for the mistake...which it was...the problem is thinking a heater (the incubator) would keep a constant temperature in a surrounding that is hotter then the temperature desired. Just as you need a heater in the winter to keep warm, you need a cooler in the summer to keep cool. The incubator has insulation to a point, and will keep temperatures steady so long as the surrounding temps are lower, but it's only a matter of time before a warmer surrounding temp will affect the incubator temp.
I live in Chicago and was running around pretty similarly to keep my tank temps down. Don't fret...it happens other people as well. It's hard for people in the South (me being a former Southerner) to understand how quickly temps can change on us. 2-3 weeks ago we got snow, and yesterday I was busy making sure my geckos weren't cooking, and today I'm back to making sure they don't freeze. I also understand about the A/C...after 5 months of freezing, 70's feel great and most people I know won't turn on the air until it hits the 80's. When your heating equipment is set to keep warm in the winter, temps can shoot up rather fast when you have a 20 - 30 degree increase outside. For your reptile's sake, it would be good to install a window A/C in the reptile room to make sure it doesn't get too warm in there. If you do that, then you shouldn't have a problem keeping your incubator in there as well.
