Didn't think it was necessary to open a new thread, so I'll tag along on this one...
I'm in the Atlanta area and my HT is above a separate garage with no HVAC. HT size is ~210 sq ft. Right now I have a 12K BTU rated Edgestar portable unit. The manual states it will cool up to 400 sq ft. It is entirely unsuitable for HT needs (too noisy), and struggles to barely cool the room. There's tons of online reviews stating this unit sucks for various reasons.
To be fair, the room does get crazy hot in the afternoon/evening to 110+ degrees.
So, here's the direction I think I'm going. I'm looking at a mini split to cool this room. All the literature/calculators/guidance I've read state I can go with a 9k btu mini split, but being that the old edgestar clunker was rated at 12k and couldn't keep up has me worried. Guess I may be comparing apples to oranges (mini split vs portable unit).
I'm leaning toward buying a higher rated unit (12k) with the DC inverter (supposedly prevents from buying an "over sized" unit.)
Thoughts and feedback appreciated.
Finally, anyone with the LG art series: working well for you?
