House Won’t Stay Cool
Hi Reddit! This is my first post so I hope I’m doing everything correctly.
I recently bought my very first house and it’s been having trouble staying cold if the temperature outside gets above 80°F. (In central Indiana if you’re curious about climate)
At first I thought the problem was that the AC unit hadn’t been replaced since 1999 so I dropped a pretty penny on a whole new unit about two weeks ago. Things were going great until the weather got above 80 and now it still can’t keep up. Yesterday when I got home from work, the first floor was at 75°F (set at 70). I called the AC company today and they came out to inspect the unit- they said everything is running smoothly and “it’s just a really hot time, all the houses are struggling”. I could see this maybe being true if it was over 100, but it’s only like 93 out.
After the AC guy left, I also left the house for a while and came back to the first floor being 77 and the second floor reading at 82.
Other things I am doing:
-changed the filter
-having a mini split put in on the second floor tomorrow
-all windows are fully covered
-almost all the lights in the house are off
-fans everywhere and bowls of ice behind some
Is there anything else I can do? Should I get an energy audit? Add insulation to the walls?
I can’t imagine the old owners were living like this.
Please help! I’m worried about my dogs, especially the old one
