I have a small bedroom (92 sqft) that gets too hot from my PC (basically a 70-350w space heater), the house was built in 1953 and already has central air conditioning that works well enough for all the other rooms. I am also renting.
Would it make more sense to get a window unit or portable? I've already used a portable unit before that I like (Whynter ARC-122DS), but I could also try a window unit that might be more efficient. Are there extra considerations for installing one in a rental space? Would it be worth it for efficiency (and cost) gains?
I'm mostly looking between the same Whynter unit, and the Midea U 8k, though I haven't looked at window units as much yet. I believe even a 5k unit would be overkill, but from what I can tell those are excessively cheap, and not just the good kind of cheap.
I have whynter portable two duct large size, it's noisy but cools well. I would never buy a single duct portable, they pull their coil cooling air from the room, so every other room gets hot air pulled in. No bueno.
Had a wynter dual hose on my sunroom last summer (250sqft, all window, no significant insulation) and it handled the space very well. It didn’t have an inverter, was only 12k BTU, so my expectation is the zafro will absolutely crush it. The inverter is also significantly more quiet, so if you use in bedroom, it may be a great option.
