LG Electronics - 10,000 BTU (SACC) / 14,000 BTU (ASHRAE) DUAL Inverter Smart Wi-Fi Portable Air Conditioner (LP1419IVSM)

LG 14,000 or a Honeywell will cool off an entire place without raising electric bill

I have an LG model and it is awesome. I use it in a bedroom in my home in Nicaragua. It uses a dual inverter technology- nothing better. https://preview.redd.it/25mjl9776p8f1.jpeg?width=3024&format=pjpg&auto=webp&s=e3be69cc6746158258082e62a2d13024a8fbe138 Keeps up splendidly with our humidity. This model is the best made currently in the world. I bought it in Nicaragua but it is available in the US…It is heavy and built beautifully. This would work in an RV

And mine is run with a completely sealed room..door kept closed…and it stays cold

Second both these ... among the quietest Midea (42 dB) and LG Dual (44 dB) - they are also pretty powerful. More quiet options here.... [https://www.soundproofgenius.com/quietest-portable-aircon-6-of-the-best/](https://www.soundproofgenius.com/quietest-portable-aircon-6-of-the-best/)

if you don't mind the price, search the LG 14,000 BTU portable AC. I've had two, and both were great. I mean, great. My apartment has a condition where it stores all of the city's hot air, and internally reaches 97 degrees come august/september. This unit churns out a cool room in an hour or 2 starting with that high temp, and my 20 ft ceilings. If you have a better starting place than that, chances are it will turn any room you have into an icebox.

>They tend to be between 35C to 40C here, even getting it down to 30C would be a massive improvement. Can portable air conditioners do that? That's a hard question to answer. Portable AC's in North America are limited to ~10,000 BTU DOE/SACC by the standard 120V 12A (80% utilization of a 15A circuit) electrical circuit that can feed them. The factors that affect how much they can cool your room depend on: - Room size - Room Insulation - Room solar heat gain (IE how much sun is blasting into the room and heating it up). If you have a dark exterior house colour your solar heat gain will be far greater as well. - Heat producing appliances/electronics within room. Before I went to a central ducted heat pump I used a single hose portable AC (LG 10,000 DOE/SACC). It was enough to cool my 14'x14' south facing living room to ~24-25C while it was 30 outside, but it was pretty much running constantly at full speed to get there, and very noisy. It had hardly any effect on the rest of the house.

I have two LG AC units. One is in the window of my main shared space and would fall onto the balcony if it fell out the window. It's a 14k BTU unit. It works very well. I also have a portable double inverter unit at 12k BTU inside our bedroom and it's got a hose that blows out the window and we've had to lock down the window portion around the hose. The hose is also supposed to be sticking outside a bit, like an inch past the window so it ensures ventilation of hot air outwards and away. This unit is fantastic and cools down the bedroom to a chill. I cannot have a window unit in the bedroom as it can fall outwards and so only a portable is permitted in rooms with windows that do not fall onto balconies.

Your unit bpt08hwtb is really a 5000btu ac. Although it does put out maximum 8000btu the heat it generates and the inefficient single hose make it equivalent to a 5000 Btu window unit. You should get an inverter unit like the lg 1419ivsm which is 14,000 Btu ashrae and equivalent to a 10,000 Btu window unit.

In selling air conditioners for 40 years the only portable that worked pretty well is the LG 1419IVSM but portables are no where near as good as window ac and only go by sacc doe rating not ashrae

LG LP1419IVSM, it's the most quiet unit you can get short of just going "... yeah I should just get a mini-split". Which you should because heat pumps are so much better than a portable AC, but sometimes you don't have that option (because laws or because you're renting) and then this is by far the best unit you can get if you want to be in the same room.
