I have an LG dual inverter. It works great.
get the LG with the dual inverter it’s quiet works great
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
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.
Same unit. It's louder than I'd like but it does the job in our bedroom with minimal fuss. Have a similar dual hose unit from LG in the main room and it doesn't cool the entire space, but can certainly reduce the temp by 3-4 degrees and take the edge off. If you can't get a window unit, you're not SOL anymore.
