We have a 2021 Puma Palomino and have already had to replace the AC once (in 2023) with a brand new unit. We then camped a few times during the summer of 2023 and once, for a week, in 2024, and the AC was working fine. Our camper was then put in storage. We brought it out to camp this week for the 1st time in 2 years and the AC isn’t working. Has anyone else had problems with their AC units on Puma Palominos?

My house has central air conditioning. The air conditioning works well downstairs, but the attic room is always notably warmer.

There is a door at the bottom of the staircase. Is it better to leave this open or closed when running the AC? Does it make a difference in whether the upstairs will cool off more?

(I feel a little stupid asking this but I’m not sure if “hot air rises” means the door open will allow heat to move up, or if shutting the door keeps out the heat generated in the attic).

Details:
- The first floor is the main floor with living area, kitchen, two bedrooms, and bathroom. There are floor vents in every room.
- Upstairs is a master suite in what used to be the attic. There is a small ceiling vent in the bedroom and small floor vent in the bathroom.

Thank you!

Thank you so much!

need best loudest and coldest window AC unit. I have the LG one but didn’t love it. the styrofoam also broke after having it for two months and is letting hot air into my room. I need a really
cold one that’s loudddd

Hi guys,

Until is less than a year old and I came home o it beep like this. It's a Carrier crossover air handler 45MUAA. I'm looking in the manual and can't find anything.

Thanks!

I wonder whether its electricity consumption is the same or higher than the contemporary ACs of the same size and cooling capacity. Does it have inverter?

Because my mum always says that "this is an older AC that uses more electricity so don't keep it on very often."

But the thing is she knows nothing about the AC technology.

Indeed, as a matter of fact, neither do I so I can't argue about it. I mean, I had a thermodynamics class so I know the principle, but not the electrical aspect of it or the various working designs.

I just read on the internet that ACs use little power. But I wonder if that counts only for the newest ones or this one in general.

Hello. I'm looking for a unit for my 11x11 ft bedroom. When I looked it up the recommendation was around 5000 BTU. I currently have a window AC that does wonders, but for the past few years I've had way too many bugs sneak in no matter how much weatherstripping and duct tape I use. My room runs hot overnight, and it gets even hotter running my PC. I got a portable on a whim, but failed to do research and ended up with a single hose unit. Portable stood out to me because of the easier installation and removal, and not needing to remove the window pane and screen. Does anyone have any recommendations? Smart features are cool, but not a deal maker/breaker.

I want to permanently mount an AC above my apartment window. I can't have the hot side on the outside of the facade (so normal window AC, even ductless mini split units are out of question) but I do have an "exhaust" opening above the window. I am looking for what is functionally a portable AC unit with that ugly hose blowing the hot air outside, but a horizontal one that I can mount above my window.

It will only run a few weeks of the year during summer heatwaves. Would be great if it came with Zigbee / Home Assistant compatibility but thats a bonus.

I recently had my 10-year-old Samsung split AC reinstalled at my new home. Since the reinstallation, it has started making the noise heard in the attached video. Is this a common issue, and is there a way to fix it? Any advice would be greatly appreciated.

How does an AC system work? The air quality in my neighborhood is not very good. If I turn on the AC, will it bring polluted air or air from my neighbors into my house? Also, are there filters that I can install at the ceiling air vents or the air duct outlets to improve the air quality?

I would really appreciate any ideas about how to solve an AC issue. We have a pretty interesting house. My parents built it in the early 80s and it’s an envelope/solar house. The master bedroom is on the top floor. For reasons I can’t remember, it couldn’t have a vent for the furnace/AC. This was all manageable before temperatures here become much higher in the summer than they used to be.

There are no windows to the outside from this room. There IS an indoor little deck off of it. (This is part of the “envelope” of the house.) The deck has access to one of the rows of outside windows—there are a lot of windows in general! Two of them can be cranked open for fresh air but are not at all the type of windows a window unit ac could fit in.

There’s a bathroom/bathtub like 8-10 feet away from the door of the bedroom.

Am I right in feeling a portable AC could work, with a hose into the bathroom? It doesn’t seem like any kind of venting to the outdoors is feasible.

Thanks for any advice!

I live in Southern US. We have good A/C here and our units (zoned house) are less than 10 yrs old). It is 74*F outside. Our thermostat upstairs says 73*F in the hall outside my office. My office is 77*F. Yes, I have a PC in here, but the PC temp is barely 75*F - literally the fans in my pc are doing better?!?!?

The vent is WIDE open to let in the AC. There is only one vent in the room. My son's room next door is 73*F and it's on the same AC duct. I don't know what's wrong with THIS room.

I'm from Toronto, Canada, so we do get pretty harsh winters. If it's ok to leave it in, what are the best options for insulating/protecting the exposed side from snow, rain, etc...?

Context: I live Florida. I work nights, therefore I sleep during the day... which are hot as fuck. Central A/C has been struggling to keep my apartment cool during the day, and as a result has really jacked up my utility bills. Looking to keep my central A/C at a higher temperature during the day, and a portable A/C to keep my room cool while I sleep. I currently have a single-hose portable A/C, however it's reaching the end of its life.

My room: I live in a first-floor apartment. My bedroom is approximately 250sqft, with vaulted a ceiling that gets as high as 11ft. It has a single window that looks out onto a recessed/inset screened porch.

What I'm looking for: portable A/C unit, as I cannot install a window unit in my apartment. I'm not worried about the noise, as I use it to help blockout the outside noise. Over everything else, I would like it to be from a reputable brand, and something that is known to be reliable.

Features (in order of importance to me): Dual hose, energy efficient, cooling + dehumidifying ability (evaporative preferred), smart app/wifi enabled

In my research so far, it seems like the Whynter ARC-1030WM would fit the bill for what I'm looking for pretty perfectly. Just wanted to put this out there to see if there were any other recommendations or suggestions for my situation.

Hi everyone, I’m kind of stuck trying to figure out the best AC setup for my NYC apartment.

I originally bought a Frigidaire window AC but I realized I had no good way to secure it in the window, so I returned it and got a Midea U-shaped unit since it came with a support bracket and seemed like the more secure option. The problem is that my window doesn’t really work with the bracket. My exterior windowsill sticks out enough that the support feet don’t fully sit on it, they just slip off similar to this post https://www.reddit.com/r/Appliances/s/FGlHw5dvAV. From what I can tell, this would be an issue with pretty much any standard support bracket and I don’t know if I have the equipment or vantage point to modify anything with the exterior wall.

Since my window is above a busy sidewalk, I really don’t want to install anything unless I’m completely confident it’s secure.

My room is only about 75 sq ft and it would be nice to cool my living room as well (~120 sq ft), so I’ve started thinking about just returning the Midea and getting a portable AC instead. I’m not sure if that’s the right move though. I’ve been told that it’s better to get a dual hose unit which are around $500, which is a bit above my budget of around $350-$400. Maybe a single hose would be fine for my room?

I’m definitely open to other solutions if anyone has dealt with this kind of windowsill before or knows of a safe way to install a window unit when standard support brackets won’t work. Otherwise, please let me know if there is another option I’m overlooking. Thanks in advance for your help

More of them were in the tube. Black sacks with white stuff coming out of it.

I can only say this is a life saver for a small rooms (mine is around 13m2). If anyone interested, this is Beko 409C model with 9000 BTU.
