      Not impressed

      The air only blows strong out of the sides of vent leaving the center of room where we can physically still feel warmth. Since it oddly blows more from sides, one would think that air would circle toward center and have some type of circulation to keep entire room at even temperature. My room is not very big and I've had other Honeywell portable air conditioners with less BTU'S keep it cooler. When you entered room you could feel the difference from the outside heat. But they never last more than two years. This is my 4th Honeywell so I decided to buy for a larger room this time (even tho it's for the same room) Sadly, it's performance is not even close to the others with less BTU's. When you walk into room now you only can feel coolness if you walk by sides of unit. You can stand right in front of vent and barely feel the air. Walk a few steps away from center of unit and you can't feel anything and literally start sweating from the heat pockets you can still feel the most of the room. The opening lid has a section in the center that apparently redirects the air thru this passage and you have to practically close this lid to feel air come out evenly from entire vent but then that also limits the air flow even if unit is on high. Even with this redirection of air flow in center you can still only feel it from sides more. What a waste of this big vent opening...and I miss the swing feature my other units had. This Unit barely keeps the room at 82degrees and must run constantly on high with heat pockets thru out the room. My other units kept my room at 72degrees evenly in energy saver mode....and on low!!! Either I got a lemon or its just poorly designed with the lid"s redirection of air flow. I liked the others better when the air blew evenly from the entire vent opening. I have had to use my ceiling fan (wasting more energy) just so the air from the unit could circulate to keep center of room cool too..I have also had to rearrange my furniture to relocate where I normally kept unit in corner. Now I have to angle the unit and move it closer toward center of the room as far as vent pipe can allow without jeopardizing that flow...just so the ceiling fan can catch the air from sides of unit better. Now an eye sore in my room with a hose that is inconveniently located but finally dropped a few degrees but still has heat pockets in room without ceiling fan. So basically the Air is not reaching/covering the footage that it should cover. And since my room is smaller than the square footage this unit is supposed to be for, I'm not impressed at all. supposedly was the best between the only two models Best Buy sold in the stores in my city according to salesman!!!! I would've returned it if only I had the cash to buy one at home depot. But I guess it's better than not having a unit at all this summer. I just wish I didn't have to pay $600 for the biggest yet crappiest Honeywell unit I've ever owned. That's double than I've ever paid. Ha! that's also the price of having credit at Best buy and my only affordable choice in this case since my last Honeywell compressor died in middle of heatwave here in Nevada... oh yes...tried taking lid off but because of the vent facing up the air just blows up and does not travel opposed to vent facing forward with air blowing out toward rest of the room...others blew air out and down especially when unit Sat on corner table. If I put this unit on table air would just keep ceiling in that corner bummed I wasn't prepared for my 3rd Honeywell to fail me and wishing Best Buy had other choices or I would've tried another brand rather than get a 4th Honeywell product. I even bought coverage this time too but they can't fix the design of the unit one salesman told me after I told all of this to him.

      Double the waste of money


      I originally bought the Insignia 450 sq ft portable air conditioner because it was highly rated and only $250. It worked like a charm, instant cold air and I actually had to turn it off throughout the night. Then it started leaking out of the bottom a few days later, turns out a manufacturing error... I lugged it into the nearest Best Buy and asked for a return which I was told no since it was over 14 or 15 days, whichever. They gave me store credit since the store only carries that brand online. That left me with the option of paying $400 or $500 for the Honeywell air conditioners. I'm a pessimist, so I paid the extra and went for the $500 model doubling my price for the geek squad 2 year warranty as well. I got this model home, and it was similar installation so it was easy. Turned the model on and adjusted the settings to cold on high. It felt slightly colder than a fan did. I adjusted all the way down to 60 degrees and there was no change... Left it on all night and it went from 85 degrees to 79 degrees in 8 hours. It was 72 degrees outside that morning. The best buy staff assured me that Honeywell was the best brand and they would be amazing but they cheaper Insignia proved way better. Did I mention my room is maybe 200 sq ft? I will be attempting to return this air conditioner and attempt to find a model that blows cold air AND doesn't have manufacturing errors... Did I also mention the box says "550 sq ft" and the item number online says "450 sq ft". Maybe I paid an extra $100 for 0 sq ft. Good luck everyone.

      Not as easy as it looks

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      My wife and I were looking to replace a window unit we had that had broken down. I was thinking more along the lines of an 8,000 BTU window unit for around $250.00-$300.00. We then saw this model, and having lived in Europe for a while, I knew these types of units were widely used. While not overjoyed at the price (over $500.00 by the time we were done) I figured it was a good investment as we could leave it in the room and use the dehumidifier if needed. What should have been as easy set up was very taxing and time consuming, in part due to the incomprehensible instructions. Installing the hose into the unit was a chore, but at least secure. However, installing the window vent and metal sealer strip in the window was a 20 minute process that left both my son and myself in a dripping sweat. Will say, however, once installed (sort of, as the window strip keeps shifting) it cooled nicely, but wish there were a way of directionally directing the airflow other than moving the whole unit. It's a good looking unit, reminding me of Rosie the Robot on the Jetson's and it's footprint is ideal for a smallish sized room. While it cools well, it doesn't feel like 12,000 BTU's, but then again, I'm not quite sure what 12,000 BTU's is supposed to feel like. If you can get past the truly baffling directions, and needlessly difficult vent installation, I think you'll be happy with it. Oh, the remote that comes with it is virtually useless; info totally unreadable, and be very careful about how you use the dehumidifier. Very poorly designed and virtually useless if used with a "Shallow pan, not included" of course.

      Skip the hassle


      In the midst of a killer heat wave here in Long Beach, I did my research and bought the best portable AC that was available in my area. I brought it home to my house/sweatbox, excited to get things cooled down. Installation was NOT a breeze. The exhaust tube that connects the unit to the window is supposed to twist together but after 20 minutes of wrestling with them they continued to fall off (both ends). A few times they did screw in but fell out whenever moved slightly. SUPER FRUSTRATING! All this time it's 96 degrees in my house. The panel that fits into the window leaves quite a bit of space around it to get the cold air out and hot air in. The engineering leaves a lot to be desires, but I was finally able to fit the tube together and get the AC going. However, after an hour of being on full blast, with all windows closed, the temperature in my house only went down from 96 to 94. After another hour, we got to 92. When you are melting inside your own house, you don't want to wait two hours for four weak degrees of relief. The room I was using it in is actually smaller than the unit claims to cover, and all the doors were closed, and yet it achieves barely more than a fan would. To top it off, when someone walks by or the wind blows, the exhaust tubes tend to fall out of their sockets, starting the installation process all over again. I plan to return this to Best Buy (if I can wrangle the 80lbs behemoth back into my car). Thank goodness for Best Buy's "generous" return policy of 15 days (!), pushing expensive service plans on customers instead of offering a reasonable return period like Target has (90 days). Best Buy staff assured me that I could return it if I was not satisfied. Let's hope that's true, will update. Many reviewers seem to feel that AC window units are much better - maybe that's the way to go. Stay cool! :)

      A bulky but relatively attractive cooling machine.

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I was very reluctant to purchase a portable A/C unit, but times are hot and my horizontal-slider windows prevent me from installing a traditional window unit (I'm a renter). It's big. It's heavy. Those were my first observations. After unboxing it, however, I found the industrial design to be fairly attractive. I'd say this thing looks about as good as any portable A/C can look. It's got a nice gloss white finish and gentle curve to the exterior, room-facing surface. The large hose running to the window is - of course - an eye sore, but it's a necessary compromise in the name of comfortable living. Let's be clear: this unit is cooling my 150 sq ft bedroom without a problem. I have not tested it in a larger space. Keep that in mind. I'm pleased to report, however, that this unit was able to drop the temp in our bedroom one night to 69 degrees when it was 98 degrees outside at midnight. After that, I knew it was a keeper. So, why four stars? I think, given the price, they could have made an effort to include a more visually pleasing hose (perhaps wrapping it in a cloth of some sort). Also, it's noisy. Just be aware. It gargles and clicks all night long. I don't have a problem sleeping through that noise, but some people might. And finally, given the price, I would have liked Wi-Fi functionality so that I could remotely turn on and off the A/C (e.g. on my way home from work). I'll be keeping it and look forward to the day when I own a house and install this unit in a garage or studio of some sort.

      Clean product, easy setup, works well enough.

      • My Best Buy® Elite MemberElite Member

      I got this unit to cool an approximately 12'X9' room with a 10' ceiling and one large window (about 6'X8'). The unit was really easy to set up which is really just attaching a hose from the back of the unit into the bottom of the window. They get a simple two plastic pieces, one fits into the other and slides to fit the window width. I unfortunately had a window that was too big for just the one plastic piece, but too large for the second as the inner piece blocked the hole that the vent attaches into. I was forced not to use the 2nd tube and just used the box Styrofoam to plug the remaining space in the open window. Bit of a design flaw, you could cut the plastic to make it fit, but I wanted to avoid that in-case I returned it. The unit remote is nice, but doesn't auto sync when you change setting on the unit itself without using the remote. It seems to have a hard time keeping the temperature below 80 on hot days in the 90's+, though this room has high ceilings and a huge window so maybe 14k BTU would have been better. The unit seems to work a little better when the temperature is set lower than you actually want so. That seems pretty par for the course with air conditioners. It works though and its got a pretty low hum while running. I have it right next to the couch and it doesn't bother me while watching TV. Great unit, maybe get the bigger model if you have strange rooms like I have.

      Design Flaw

      • My Best Buy® Elite MemberElite Member

      I bought this unit to replace a 8000 BTU window unit that was barely cooling the room, so I thought moving to a 12000 BTU would improve the overall cooling. The room is upstairs (bonus room), but well insulated, and about 330 square feet of a single room. I carefully followed the installation instructions. The net result is that it did not cool as well as the 8000 BTU window unit. It my opinion, it appears to suffer from a design flaw on the way the compressor is cooled. There is an exhaust port to the outside, but there is no intake port except from the room you are trying to cool. This appears to cause a slight vacuum on the room, causing air to be pulled in from other sources, like the threshold of the doors in the room. The problem is that the outside temperature here in the spring can be 80 to 90 F (and summer is higher), with high humidity and when the temperature was set on 68 on the unit, it never got below 76 - 78, even at night, as indicated on the unit. The unit air output temperature was measured at 53 to 55 F, so that does not appear to be an issue. Overall, I am disappointed in the overall performance, and I am returning the unit.

      Quick, and cool

      Bought this unit prior to hurricane Irma making it's way through. With it's low watt usage, it was a GREAT fit for my bedroom, and generator. My generator was running 2 refrigerators, a few lamps, and this AC unit. The Honeywell unit used so little power, I've decided it's cheaper to run it in my bedroom and keep the rest of the house a bit warmer. While some people complain about the noise, mine it almost TOO quiet. I have to have some sort of white noise to sleep, and a cold room. This unit provides both. The noise isn't a nuisance, but JUST right. The dehumidifier is amazing, and is large enough to be able run for 24 hours without needing to be emptied. I'm tempted to buy more for the front of the house that gets warmest in the summer heat. To give a comparison, we have a top of the line Trane 21 SEER ac unit in our house that keeps it nice and cool. Adding this unit to the bedroom, I can get the temp to a nice 60 degrees, wicked fast. Our power never went out during the hurricane thank goodness, but a co-workers power did. He borrowed the unit and was amazed and bought his own.
