AC Recommendations For Cleanliness / Maintainability & Noise Considerations In A 350-ft. Rental Cottage?
I need to get an AC for a small cottage apartment I moved into on Long Island, NY last fall. Realistically my options are either a window unit or a portable AC.
One of my biggest concerns is cleanliness / maintainability. Every window AC I've ever used was disgusting internally - mold, biofilm, dust buildup, etc. In my last apartment, the AC was built into the wall and impossible to fully remove or properly clean. I disassembled and cleaned everything I reasonably could, used coil cleaners, etc., but black gunk would still reappear instantly & be spit out. In the end I had to slap a MERV 8 filter on the output and call it a day until I moved out.
While I'm open to window ACs, I really do not want to repeat that experience. I need something I can clean and maintain easily in a humid Long Island climate.
So my first question would be: Are there particular models that are notably better from a maintenance / mold / cleaning standpoint?
Noise matters a lot too. I'm a bassist/musician, and what tends to drive me insane isn't airflow noise so much as low-frequency compressor rumble / resonance that masks bass frequencies in the room.
The maintenance issues also have me considering portable ACs, since many seem easier to fully inspect and clean. But I also know portable units are generally considered significantly worse thermodynamically than window units - even dual-hose models.
I've been researching units like:
- Midea Duo
- LG Dual Inverter
- Whynter inverter dual-hose models
But each seems to have tradeoffs:
- Midea Duo seems thermodynamically ideal, but I've seen a lot of owner discussion about hidden moisture buildup and difficult deep-cleaning.
- LG Dual Inverter seems more flexible physically/acoustically, but it's single-hose.
- Whynter seems promising as a middle ground, but I haven't found as much long-term owner feedback.
A complicating factor: the unit probably cannot sit directly below the window. It'll likely need to sit somewhat off to the side, so hose flexibility/routing matters a lot (meaning the Midea with its bulky hose-in-hose design may not work, for instance).
The apartment itself is only about 350 sq ft:
- 1 bedroom
- open kitchen/living room
- bedroom separated only by an open doorway
- only actual closing door is the bathroom
Budget-wise, I'm flexible. Cheap is nice, but I'd spend up to ~$600ish if it actually solves these problems and doesn't become impossible-to-clean nightmare fuel after one season. I'm also not sure how long I'll live here, but I'd like to ideally bring what I buy to the next place if it doesn't have central air (augmenting as necessary for larger spaces).
Given all that:
- Would you still strongly recommend window units over portable?
- Are there particular models that are notably better from a maintenance / mold / cleaning standpoint?
- Are there dual-hose portable models with reasonably flexible hoses for nonstandard placement?
- Any thoughts specifically regarding low-frequency noise / resonance?
