it's been in high 80s and low 90s. We have a small house (under 90sf) and a window unit but it does cool the whole house. We have ceiling fans that run all year. The temp is always at 72-73. it will get hotter but the temp inside will be the same. Little guy Brutus does not like being outside even after a haircut which is now on a monthly basis. Husband likes to tinker outside but he does know when to come inside. This weekend was extremely busy showing houses. So I got my sweat on. Ofcourse the properties had no a/c. thank goodness for a/c in the car.
