Can I cool a 4k room with 14,000 BTUs?

Toshiba compressor, should be ok. Note warranty only valid after a licensed contractor fills out install papers and provides license #. So forget warranty if diy. Be sure to know your unit. Never run in economy mode and watch out for timer features (you'd be suprised how many times I hear "it keeps shutting down" when the client had a timer mode active)

I know you get what you pay for. I don't need to cheap out, but I don't want to blow my wad on a Mitsu again. Still looking for something middle of the road. Maybe the Panasonic.

Thanks for all your help guys. I think I rep'd everyone.

In all honesty back in Missouri I had a 12kW room with CO2. Ran a 4 ton Mitsubishi unless it was in the 20's. Then I switched to a massive blower with filtered intake. The large cfm squirrel cage air handler came from the split ac evaporator that I tore out to empty the basement for growing. This blower and the CO2 generators controller were run off a green air environmental controller. Instead of being at 1500 ppm constantly, it was more like 75-85%, colder the better.

Run an exhaust that's larger than the intake and use inline ozone to scrub odor.

Winter runs were always very comparable in yield to summer. Quality of winter run was just a cunt hair better.

I can't catch a break.
I have a 10'x12' flower room in the southwest U.S. where sumertime temps are easy 115 for a moth straight. I have 4 1k lights on a closed system. Pulling from another area & expelling in another, never touching the flower room.
4- magnum xxxl 8' hoods
1-760cfm fan moving air for them.
1- 12,000 btu window a/c
promix- no need to cool water.
I run my lights at night 6pm-6am
6' fan & filter scrubbing air.
all ballasts kept out of room.
no heaters
dehumidifier in room
the 12,000 btu works great with all 4 lights in winter. 2 months a year in the summer time I shut down 1 light & run 3 lights or the a/c would be running more than I want it to. It will cool the room but really working for it.

Thanks Remi1. I'm at the point now where I've found the dual 18000 btus that I need, and I can afford it. Right now, I can't find a dual that will still cool when in drops below 10 F outside.

Cheers

2 4k rooms, side by side, on a flip. each 4k room will have it's own inline fan. both fans will be on 24/7, so I'll be stacking 2-700 cfm fans to cool 4k.

I know I said I wasn't going to buy another Mitsu , But, I think I've finally decided.

I'll call tomorrow and double check operating temps but I think the Mitsu goes down to 0 F.

It's really hard not to cheap out though http://www.airconminisplits.com/product/dual-zone-18000-btu-16-seer-mini-split-heat-pump-ac-aircon-a16ci4h4r36
You get what you pay for. You will be kicking your ass if that mini dies during a summer run cause you got a cheaper one.
