I currently have a little 5,200 btu a/c in my room that isn't cutting it. It's in the mid 80's here and already I'm having heat issues especially with my 110g 2x250 mh
's. I need an air conditioner to cool 2 rooms that are connected, each room is roughly 12x12, anybody know how big of an a/c unit I'll need to keep these rooms around 68-70? I"m not sure if this air conditioner isn't working or too small(thinking maybe both) but it's about 78 in my rooms with this running full time.
