I’m in Hartford, Connecticut and my apartment has those old double-hung windows that don’t seal well. I’m looking at the Whynter ARC-14S to cool a bedroom this summer, but the window kit is my main worry. It’s a dual-hose unit, which is part of why I’m considering it, but I’m not sure the plastic slider panel will fit the odd frame width without gaps letting hot air back in. I’ve read conflicting things online about how well the included kit works on older windows and whether people end up building their own insert. I don’t want to buy something and then find the exhaust setup leaks or the unit trips the breaker in this old building. Has anyone here dealt with a similar window situation and a portable AC? How did the sealing go, and would you go dual-hose again?
Update after looking around more - Whynter ARC-14S Portable Air Conditioner Review came up when I searched on the window kit. Still unsure it’ll seal against my old frame, so I’m leaning toward trying it with a homemade insert.
