Quiet, efficient split; but mold issues and bulky.

The ARC-14S and ARC-14SH are exactly the same. The heater function is nice to have but remember this is an AC with a heat option. The room will be to be higher than 45 degrees. The ARC-1230 models are really nice. I love the upgrades and the use of the app. I'm in AZ so I know what you mean when you say you're dying LOL.

Recently had success in my attic with the “Whynter Portable Air Conditioner 14,000 BTU & Heater with Dual Hose”. It cools about 500 sqft no prob

Unfortunately Amazon is the best and cheapest place to get things like that “off season” (even though it’s broiling in Oakland). It looks like they’re doing a sale on summer type stuff next week starting the 25th so if you can wait it might be best. To answer your question better, we absolutely love the “Whynter Portable Air Conditioner 14,000 BTU & Heater”. We leave it hooked up most of the year because it’s dual hose so it can also blow just outside air instead of cooling and is way more efficient than anything except a window unit. It’s not cheap, but the amount of extra sleep we’ve gotten due to leaving the windows closed the entire summer is huge. It’s highly rated and we’ve spent no extra money over 3 summers with it. Just hand wash the filters.
Whynter ARC-14s, was my primary first Floor AC until I got central.
Whynter ARC-1230 or ARC-14S Dual hose and 14,000 glorious BTUs. Not cheap but they're the best of the best.
