I heard there is a shortage of AC units and parts so I wouldn't dilly dally too much.sikacz wrote: Sat Jun 19, 2021 11:02 amHave shop fans and opened vented window on the upper floor. It’s already near same temp outside. We just went to a petsmart and bought one of our cats a cooling pad. LoL. Can’t really keep doors open, but I have cracked some windows. We have a portable AC unit on the first floor and shop fans to push the air up. AC guy is putting a proposal for two AC systems, one for our first floor and a larger unit for the 2 nd and third. I calculated the first could do with a one ton, the old is a 1.5, but I’ll see what the proposal says. The larger system will be a 3 ton. All I can do. Need to open up some wall and ceiling for new lines.CDFingers wrote: Sat Jun 19, 2021 9:24 am Put a fan in a doorway on the floor, so it pulls in the colder air. Open the top of the windows to let the hot air out.
