Cooling A Large Space Without Central Air

[sourdough]

I know this MB is primarily concerned with garage/shop stuff, but:

I want to know: Who besides myself attempts to cool a large space (1500' or more) with one or two window/thru-wall units at 90*+ OSA temps?

I'll start (maybe ad nauseum) by saying I have a 120V LG 15K window unit located centrally in my 2100* ranch home, in conjunction with the forced air furnace fan to distribute the air throughout the house. When we catch it early (OSA is 3*-4* warmer than the interior), we close all exterior openings and start the window A/C around 75* interior temp.

We live in SW WA State and this summer is fairly normal. It is now 96 * OSA and the interior temp is 75* at 1600 hrs (4 PM for you civilians).

It works for us.

Interested in other experiences, please.

Thanks for putting up with my posts.

What is the typical relative humidity up there?

If you already have forced air why not just add central air to the system?

I cooled my 1000 square ft shop in NY with two window units mounted through the walls. The both had thermostats on them and I left them on all the time. If the OA stayed below 95 I could keep the shop around 75

Summertime is our dry season, around 50%-70%.

Cost, compared to a $400 window unit.
