It's COLD inside!

Reviewed in the United States on July 24, 2016

House has central A/C but the master bedroom (12 x 15) stays hot because it gets the most sun (live in FL) and is furthest from the A/C unit. I've had to turn the central air down to 76 to keep the bedroom at 80. Decided to try a portable unit (HOA prohibits window units) to see if that would do the trick. Got an excellent deal from Amazon Warehouse on a used "Like New" unit. Happily, no problems and it's working like a champ (I've hung onto the box, just in case). Gets downright cold in bedroom now. Because the whole house is under A/C, this unit probably won't have to contend with removing humidity. Nevertheless, I placed it in a water heater drip pan. Better safe than sorry until I'm sure there won't be a leak. I also wrapped and taped the duct with Reflextic Wrap which probably helps efficiency. I don't think it's too loud, but then again, I sleep with a white noise app. Won't need that now. Overall, I'm very pleased with this unit. If anything should change, I'll update accordingly. For now, I definitely recommend it!

Update: 7-04-19
I've had this unit for 3 years now and it runs every single night for about 9 months of the year. Other than washing the filter monthly, there has been no maintenance required. This thing lowered my electric bill $50/mo because I no longer need to cool the entire house at night....just the master bedroom. That's well in excess of $1000 over the past 3 years. The only time I've removed the hose from the window is during a hurricane. Once the power is restored, it goes right back into the window and back to work. My house A/C is probably going to last longer because of this little unit, too, because it doesn't have to work as hard 24/7. The one issue I had is that the MBR circuit is only 15 AMP and we have a lot of power fluctuations so it would occasionally pop the circuit. I bought an appliance-rated extension cord, plugged it into an outlet on the master bath circuit (turned out it was only 6' further along the wall), and no problems since.

If this unit ever conks out, I'll be ordering another the same day.

Stay away, it's highly overpriced

Reviewed in the United States on August 6, 2017

Does it do the job to cool a room? Yes.

HOWEVER everything about this unit is cheaply made and lacks in quality:
1. The remote is almost entirely useless. Unless you point it directly at the unit, the unit will not read the signal. That's even if I am 1 foot away from the unit. I bought a $10 LED remote controlled lights and their remote performs great. However for $400 Honeywell could not find the budget to make a remote control with reliable signal.
2. The plastic is extremely cheap. I bought this unit because it's portable and I wanted to move it between my bedroom and my office. Every time I try to roll it I feel like the plastic is about to crack open. One has to be extremely gentle if they try to roll the unit around on carpet.
3. It has a drain hole on the back of the unit. However the hole is so low that it almost touches the ground. Meaning you can't put any pan/container under the unit in order to gather the water. Also you can't attach a hose to it. The only way to put anything underneath is if you lift the unit on something and create extra space for a container underneath. Keep in mind that the unit is 64lbs. and as I said above the plastic is about to fall apart every time you grab it.
4. The window frame is about the cheapest thing I've seen in my life. I had to put some paper between the two pieces in order to get the pieces to stabilize and not wobble like crazy. Also the plastic pins fall out easily. Also because of the plastic pins you won't be able to seal your window and there will always be a crack between the window and the plastic frame of the unit. Also keep in mind that to replace the plastic frame it will cost you around $30 and it's hard to find.
5. The FAN NEVER STOPS. Even if the unit reaches the desired temperature the fan of the unit never shuts off. Meaning there's ALWAYS noise around this unit. I am saying this because unlike your eyes you can never close your ears. They are always open and absorb every sound. Thanks to this unit my ears can never rest. It's either putting ear plugs and missing my phone alarm for work or listen to the annoying fan all night long.
6. It has no heating option. For $400 they couldn't incorporate a heating option, really?
7. It has no filter. Again the unit costs $400, it's bulky as hell but they couldn't fit couple filters so that it would filter the air as it cools it at the same time?

This is the second honeywell product I own and I don't think that I will ever go for this brand again. I noticed a much better build Delonghis at Costco. Perhaps you could consider that as an alternative. It was also a little cheaper than this unit.

excellent unit, poorly designed exhaust system

Reviewed in the United States on May 23, 2017

Verified Purchase

At this writing I only ran it for 3 days as a supplement to my upstairs 400 sg ft bedroom to not use the central during the night.
Functionally I am more than satisfied.
I had a window style conditioner but the vibration kept me awake, This unit does not make any mechanical noise only the sound of the air from the vent; very consistent like a fan; doesn't bother me at all.
I gave this 5 stars as the unit is the main reason I bought this, not the exhaust system.
My only complaint is the exhaust system, rather cheap for such a nice unit.
If the length of the vent hose would have been another 12 inches longer, it would have worked ok.
The rubber lock unit is all but useless, I put a screw in the hole to lock in the Window Filler unit to size.
The snap of the Tapered Adapter to the Window Filler unit is also useless. I had to gorilla glue the Tapered Adapter to the Window Filler unit to keep it from coming apart.
I feel the Honeywell needs to revisit the complete exhaust hose system and maybe come up with a slightly longer insulated hose, as it does get warm while running the air conditioner and the warm hose is still in the house, and a better assembly system than a rubber plug and weak snaps

It's an okay air conditioner, if you know how to treat it.

I bought this product in 2018 for my living room, which I assessed to be 450 square feet. However, it doesn't completely cool the room. It makes it comfortable around 76 to 77 degrees depending on the temperature outside. I wish I would have bought a 12,000 or 14,000 BTU model. I just thought it would be overkill for my living room, but in retrospect it would have made a difference. Now I am using it this year, and this is where additional problems occurred. We had a heat wave in our area for about three days. Temperatures reached about 95 degrees but it felt like 100 degrees in actuality. The air conditioner worked okay the first two days, considering what I just stated previously. However, on the third day it would continually affect my circuit breaker. At least three times i needed to turn back on the power in my apartment, because the circuit breaker was tripped. So on the last day of the heat wave i was stuck in extreme humidity and heat on the hottest day of the heat wave. The day after the heat wave i thought the unit conked out on me. I read reviews in which it would cost about $75.00 to $100.00 to send it back to Honeywell and get it fixed. I read horror stories from the reviewers about Honeywell not honoring warranties. Therefore, I decided to call some local air conditioner repair shops. The first shop I called said we don't service your particular device because it would be hard to get the part. I called another place and they told me to bring it in but wouldn't give me an assessment over the phone which worried me. I was frustrated. Therefore, I looked online to see what I can do. Visited various sites and received recommendations. The obvious recommendation was to clean the filter (which I do every two weeks). The one recommendation that appeared to work for me was to make sure when you set the thermostat, make sure it is 5 degrees lower than temperature in your room. That helped a lot. The air conditioner is working now as i am typing this review. So the point of this review: The device is okay when it comes to cooling your room but don't overexert it. I used to put the thermostat on 61 every time I started it up, I changed that behavior and now I put it five degrees below the temperature in the room, and continue to decrease it by five degrees to a desired, comfortable temperature. If you push it, it will not respond well and just cut off!

Good Unit for $350

Reviewed in the United States on October 24, 2016

Verified Purchase

I've had this AC for the last two SoCal summers and it has been working great so far. It will be plenty for a mid to large bedroom. Like all AC's, they are rather loud machines so plan on needing to jack up your TV volume. But you can turn it on for 20-30 minutes before bed and then shut it off for a good while, depending on how hot it is and how well your room is sealed from outside air. The thermostat works pretty well too, so you can leave it on all night and it will kick on when needed. The auto moisture evaporator seems to work great with this unit also. All-in-all a great little unit. Small size compared to other portables, easy set-up, and the fan throws a lot of cold air!

Powerful and quiet

Reviewed in the United States on January 17, 2019

Verified Purchase

Had it for all of last hot California summer. It took a little more effort to install than I would prefer to. In the end, it fits pretty well into the window - and most important, there are no holes, so hot air doesn't get into the room. The hose could be a little longer - the way it is, the device needs to be very close to the window.

But once installed, it's really nice. Very powerful, and very quiet. Keeps a fairly large room cold. Also, while it is near the wall - it circulates the air sufficiently well, so that the whole room has reasonably consistent temperature. It's important when you set the thermostat - you don't the temperature near the device to be 60 - and 10' away to be 80. NOTE: we use it for air conditioner only.

Got Here Fast AND Easy to Assemble

Reviewed in the United States on July 21, 2018

Verified Purchase

With an upcoming heatwave, I was so happy and relieved that it got here so fast!! It was thoughtfully easy to assemble — all the way down to the folded corner of the support tape, just to make it easy to remove!! This is the second Honeywell AC I’ve bought because of the efficiency of my first one AND because of the trusted, positive reviews. This model is very powerful, so I have it on a long extension into the storage room that’s hardly used. It still flickers the lights, but it has not shorted-out. I’m in a condo, so I know the power is not like a home. I’ve had the living room shortened by a hairdryer, so I use a lot of extension cords to divide the power as much as I can.

I haven’t cleaned or used it for more than a day, but so far I am thankful for both the fast delivery AND Honeywell.

Cools fairly well but not as good as window unit

Reviewed in the United States on August 3, 2015

Not sure why people are saying this is quiet, because it is LOUD from my perspective...when on high you can't have a phone conversation in an office room in your house. I have a 12X12 home office and use this for that room as I shutdown the AC for the rest of the house during the day...for this purpose it does work and it cools the room, but not as good or cold as a window AC unit because of how it pulls air from the other parts of the room/house..If I leave the door open a crack, it will actually pull the door open about 2 inches as it pulls air out of the rest of the house...so design would have been better with air in and out ducts into the window piece that they give you. I opted for this because I hate window units, they are ugly from the inside and outside and are annoying to take out and abuse the window opening and molding. Could it be colder yes but it does alleviate the high temps on a 100 degree day, but it will run almost 100% of the time to keep it cool, so not very efficient and cost effective but it does save my home unit from kicking on and off all day. I would rather save the life of my central air unit and beat the crap out of this thing for the price.

It's just ok - doesn't realistically cool to the lower limit it says it will (61)

UPDATE 7/7/17: I wanted to say I had a fantastic experience with the Honeywell customer service. They asked me a few questions and had me take a couple pictures of the unit to test the temps it was putting out and they scheduled to have a replacement unit sent immediately. The replacement unit itself was unfortunately stolen after being delivered to the wrong address by UPS but Honeywell customer service again sent another replacement out which arrived overnight and seems to be working like a champ so far. It may not been an icebox in my room, but I appreciate the lengths the customer service rep went through to make sure I was taken care of.

I've had this about a month at this point. I wanted to give this some time to experiment to see if I could make it function better. I understand the pitfalls of the single hose units and maybe it's just related to that, but it's not the best. It works fine, controls and remote all function properly. Installation was fairly easy, though I had to fill some cracks in the window vent to prevent hot outside air from coming in the gaps.

I've got insulating blackout curtains in the windows in my bedroom since I get direct sun mostly all day, but the room itself is less than 200 sq feet. I've set the unit at its lowest setting (61 degrees it says) and I've yet to see it go lower than 73 even at night with no sun, doors closed, and running all day. I'm going to try some foil insulation on the windows to completely block the light in hopes that it helps. If the unit actually cooled down to 61 I think it'd be great, but I haven't seen that happen and we're not even to the hottest part of summer. May have to get a small window unit to compensate.

4 Years, not without issues *UPDATE* It's Leaking!

Reviewed in the United States on July 28, 2020

Verified Purchase

Some people said it's really loud, I say... it's semi-loud. It's an indoor AC though, what the heck do you expect?

*UPDATE* Two weeks later... went to change the water, there's some sort of oil or refrigerant leaking into the water, was all shiny like oil in a puddle.

Cons
- The thermostat can freeze up or get cold with extended running, currently mine is reading about 8-9°F below actual temperature. Usually it's always a few degrees off. Helps to drain it though, if it's full it might even read -20°F below actual temp.
- You can get scubba/crud accumulation on the fan flades. Mine wasn't blowing very well, I finally realized it was the junk on the blades, cleaned them and it started blowing wonderful again. But it's nearly impossible to clean. Which leads me to...
- WAYYY too much of a pain to take apart. I took the thing apart to clean it out, AC's lose a LOT of efficiency if you don't regularly clean off the heat fins and such. Had so many screws in so many weird places and it's not at all use friendly or maintenance friendly.
- Very poor drainage: When you go to drain it, you have to drain 2 places. Also, the lower drain, I thought I was getting all the water and they say to put like a pan under it for draining (I don't know what pan on Earth would fit below it). I was having issues, so I finally picked up the entire unit, and tons of water poured out. But it's nearly impossible to drain it completely. You can only get like 4/5ths of the water out of it. But if you have the top drain open still, even after you thought you drained it, more will come out. It's a mess.
- Off-Gassing: I swear there's some very odd smells / odors coming from it. Could be from extended running, could also be coolant, but... it's very cheaply made. When I opened it up, I wasn't very impressed with the piping. I'd be amazed if these things did NOT leak.
- The touch sensor buttons are nice, but I always set them off on accident. It turns off WAYYY too easily. And if you turn it off, you're not supposed to turn it back on immediately.
- The exhaust vent needs a better locking feature.

Other cons related to portables:
- It's super inefficient. Portables are even more inefficient than regular window units. Especially DC ones.
- The top drain plug is in a horrible place because it's right next to the exhaust. They should have moved it over just a hair. I like to insulate my exhaust pipe because it's basically a wood stove pipe... giving off heat.
