Customers are saying

Customers express satisfaction with the 450 Sq. Ft. Portable Air Conditioner's cooling power and its ability to cool their entire apartment quickly. They also appreciate its easy setup and portability. However, some customers find the noise level to be a bit loud on the high setting. Additionally, it requires a window to be open in order to use it, which may not be ideal for all users.

This summary was generated by AI based on customer reviews.

      We are sorry to hear this, and we wish you would have got in touch with us before returning this
      unit ! Our portable air conditioners work best in enclosed, well insulated spaces. Room environment conditions such as ceiling height, sunlight, number of windows/ doors and level of insulation can affect cooling efficiency and there are ways to increase the capacity of these units. There could be other reasons for the unit to not cool- temperature setting could be too high, or the exhaust hose may need re-installation to avoid the heat from coming back into the room. Please do give us a call at 1-800-474-2147, Monday - Friday 8:30 AM - 5:30 PM (EST), or send us an email at [email protected] with the reference code number BBA0711. Our customer support team will be able to suggest another unit to meet your requirements. Thank You ! JMATEK

    Stands well above other Portable ACs

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Over the past 6 years we have owned 5 different brands of portable ACs. 3 are currently being used and 2 have met their maker. We currently have a DeLonghi in our daughter's room that does a good job. The main benefit of this unit is that the cycling on/off is not so jarring it can wake her up. In our main room we have a Royal Sovereign which is loud and clunky but does a decent job of cooling. A portable AC rated at 10,000 BTUs is good for a medium sized room in a not very hot climate. We live on the coast in Los Angeles and this one does very well in a 12x15 room. We just had a heat wave where the outside temp got up to 85 and the humidity was around 70%. This unit took a while to cool down the room in the evening but not that much longer than our previous, 12,000 BTU unit. Another thing this was a good test of is how well it evaporates moisture. Too many units need to have the drip tray emptied after only a few hours of running in moderate humidity. We have not had to empty this one after almost 3 weeks and close to 100 hours of running. Pros- 1-Nice control panel that lights up to touch and shuts back off after a few seconds. 2-A beep that is loud enough to hear but not so loud that it wakes up my wife if I need to change a setting when she's asleep 3-Cools very well for its rated BTUs 4-Decent looking and not too heavy 5-Came with everything needed for set up Cons- 1- Display is a little too bright when it's on. It seems blinding in a dark room. But it does shut back off after a few seconds so it's not horrible. 2- It's just a little too jarring when the compressor turns on and off. Part of this is that the compressor and exhaust fan start and stop at the same exact time. Our DeLonghi and our old Everstar both offset these 2 so there isn't as much of a sudden jolt on or off. Having said that, it is no where near as jarring as the Royal Sovereign in our main room. Overall, I really have to sing the praises of this unit. It does a good job of cooling without making too much noise or taking up too much room. I've had units that had to have a permanent drain hose, some that are way too loud to use in a bedroom but this seems like a very well engineered and built unit. I am hoping to have this one for a long time.

    Fair to average - with caveats

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Our central A/C system broke down at the beginning of the hottest weekend of the year; it was in the area of 115+ outside. Not good. Our ranch style house was built in 1957 and insulation didn’t seem to have been a priority with the developer as our place seems to be essentially devoid of any. It quickly became over 95 degrees in my living room. I needed a portable A/C unit quick to at least make the bedroom tolerable until the central system could be fixed. After a quick look on the Best Buy website, I decided a 14,000 BTU model would do the trick in the short term but when I arrived at BB the only unit still available was this one at only 10,000 BTU. I could order one of the more powerful units, but then I’d have to wait several business days for delivery. Still, I was hoping this could at least make the 10’ x 12’ bedroom endurable. Before I proceed, I really must warn you. The manufacturers of these type of units all stress portability. Sure. Be advised that this is extremely subjective and qualified! Technically, yes, it’s indeed portable. But so is your washing machine if it has casters. And so is a piano. Out of the box, the actual unit itself seemed decent enough, but unfortunately two major shortcomings were immediately obvious. 1) the duct hose supplied is about 4 feet long when extended, which is far too short for flexibility (no pun intended) of location. 2) the power cord is, likewise, far too short. If you are not fortunate enough to have a window that isn’t too high from the floor AND has a power outlet in its very immediate vicinity, you are going to be right out of luck (actually, SOL). If you’re thinking, “No problem, I’ll get a longer length of duct hose and just use an extension cord” then you’d be wrong. The manual very specifically states that using another duct hose and/or a longer length of hose will end up causing a malfunction. It also states very plainly to NOT use an extension cord. I was lucky and the window/power outlet arrangement I had to deal with was just barely within the dimension parameters to allow the unit to be connected. I had to rest the unit on a small table to make this arrangement work and had to place a towel on the table so the casters wouldn’t allow the unit to simply roll off at the slightest provocation. I suppose I could’ve upended the unit and removed the casters, but I wasn’t inclined to do that. After fiddling with the supplied window kit, I had the ducting hose set up and faced the moment of truth. I turned it on and enjoyed a nice blast of cold air. Success! The temperature window displayed ’99.’ Could that be right? Maybe… it was awfully hot in that room. As the display only utilized two digits, it may well have been hotter. Yikes! I figured, “Oh well, in an hour or two at most it ought to be more bearable.” After twelve hours – yes, that’s not a typo – it had cooled down overnight to a mere 83. Did I mention I also had the room’s 52” ceiling fan going at its fastest speed and two stand-alone fans belting away? In conclusion, I would have to say that this machine is a step up from just opening the fridge door and sticking your head in, but not by much. If you have a very small room and aren’t dealing with such extreme temperatures, you may find this adequate. I will be returning this and exchanging it for a more powerful unit once they are in stock.
