Hi all-

I have a photography studio in Los Angeles that desperately needs AC.

Space is:

7000sf, divided into two spaces.

North facing,

Concrete construction

11' ceilings

Second floor,

Windows on 3 sides.

While I know Mini Splits with heat pumps would be ideal (and costly!), I'm considering multiple 220v 25k BTU window units like THIS. (Koldfront 25,000 btu) Rated to cool 1500sf, and heat approx 700sf.

I'm thinking 3x units (75k total) in the front space (more solar exposure), and 2x (50K total in the rear space, which tends to be cooler overall, as it has only 2 sides of windows and much less solar exposure.

For reference, we are currently running 3x 14k (42k total) BTU commercial portable units in the front space, and they're working full time to keep the place semi-comfortable.

I'd appreciate any input from HVAC pros if I'm insane to even try this.

Thanks!

Tim
