Enjoy Peace of Mind
Built-to-last, a Washable Filtration system protects & extends the life of the AC, while thermal overload protection on the compressor and motor, means extra safety precautions for added endurance and peace of mind for you and your family.
Easy Clean Dust Filter
The Washable Filtration System filters dust, pet dander and hair from entering the unit – Helps reduce impurities in the air and is easy to clean by running the filter under a faucet.
Save Time, Save the Heavy Lifting
All accessories are included for a quick installation on vertical or horizontal windows. Roll the AC to your preferred cooling area, set up the window kit, switch the AC ON and Voila! Immediate cooling without the heavy lifting of traditional window ACs.
Save Energy, Save Money
Reduce the energy consumption of whole-house central air conditioning by setting up a Honeywell Portable AC in rooms that you actually use.
Honeywell Portable AC's dual motor technology means lower noise levels. At the highest speed setting, the Classic Series Portable ACs produce between 51 to 54 decibels (depending on the model BTU). That's about the sound level of an average conversation between two people in a quiet room.
Set It & Forget It

Easily view current and desired thermostat settings from across the room. The lighted control panel with feather-touch controls adds that extra touch of elegance coupled with the shiny smooth body of this series.
Easy to Maintain, Easy to Store
The Self-Evaporation system means bucketless operation. In higher humidity rooms, the unit is equipped with dual drainage options offering you flexibility. A continuous drain system can be set up in minutes when used as a Dehumidifier. At the end of the season, simply roll the AC into a storage room until next time.
Check how your room environment conditions will affect the cooling capacity required for your room.

The day our air conditioner arrived it was well packaged to prevent damage during shipping. The UPS guy had no trouble lugging it up the stairs alone, though if you have to pick it up and move it it's actually kind of heavy, just under 70 pounds according to our bathroom scale. It has wheels, and they aren't those little half white wheels that come on appliances, but they are actual roller/caster wheels so they roll easily on carpeted bedroom floor.
When you open the box, the following is inside: Honeywell MN12CES portable air conditioner unit; Remote control; 1 plastic window bracket panel adapter; 2 plastic pins; 1 plastic hose connector; and one plastic hose. I thought I had everything that I needed when I purchased this air conditioner, but I didn't.
The window bracket panel adapter is what needs to fit in your window. Fully closed it will fit a window 19" tall or wide. Fully extended it will fit a window 46" tall or wide. I live in an average apartment, so I assumed that this kit would work for my bedroom window, which is pretty small overall. It did not work, and was not long enough. I called Honeywell to see if they offered any kind of extra length available for free or purchase, but they their window bracket panels do not link together. What I mean is that if you have the included window panel kit and buy a second one, they can't be hooked together (easily anyway). Basically, if your window is larger than the 48" you are on your own to figure something out, and Honeywell did not offer any suggestions. Our window is 56" tall.
We went to Home Depot. I'm not huge on home improvement products, and I talked with a guy near the air conditioners who showed me a kit that would fit my window which was $200! Having just shelled out over $400 for an air conditioner, I wasn't about to spend $200 on a window kit. He suggested some cheaper, "rigged" alternatives like a wooden or foam panel. Unfortunately, my apartment complex won't let you piece anything together like that, so I wasn't sure what to do. I did the only thing I could think of at the time and ordered another window bracket kit from Honeywell, even though I knew it wouldn't connect to the existing kit. The additional window kit was $32.
When the window bracket kit arrived, I paid close attention to the bracket included with the air conditioner and it has these tiny, thin, flimsy, lightweight plastic "pins" that hold the bracket together. Let me rephrase that, they are supposed to hold the bracket together. However the pins don't lock into place, so they pop out if you barely touch the window bracket. I knew there was no way they would hold up overtime. I used Scotch Permanent Outdoor Mounting Tape and slid it in between the non connectable panels of the two kits, and BAM, I was left with one long piece, perfect for our window. I did push the plastic "pins" into place for good measure, I vacuumed one of them up a few weeks later and we never found the second one, they definitely did not stay in the bracket panels. You put the window kit in the window, with the screen in place, which is great because it keeps bugs out of the exhaust hose.
Speaking of the exhaust hose, it is made of plastic, all one piece, and extremely flexible, like a giant bendy straw. It's 5" in diameter, 12" fully closed and 48" fully extended. You snap the hose on the back of the air conditioner, snap the window bracket panel adapter onto the other end of the hose, and then the adapter is what snaps into the window bracket. Getting the adapter to snap into the bracket is a bit awkward if the bracket is already in place, but it snaps in tightly and stays securely once you get it in. When you are figuring out where to position your air conditioner, keep in mind that the exhaust hose cannot be at a ninety degree or any type of steep angle, or the exhaust doesn't properly vent out and can break your air conditioner. You want it to kind of make a "ramp" from your window to the back of your air conditioner.
Also not included was something to put around the window bracket for a tight and waterproof seal. If you don't put anything around it, and you have straight windows, you probably won't have a problem. If you have slightly crooked/weird/abnormal windows like we do, you let your cold air outside and you let the bugs inside without something to seal the gaps around the window panel. I purchased M-D Building Products High Density Foam Tape 23111 (1/2"x3/4"x10') and not only did it make for the perfect seal, but it did not require any additional adhesive, and stuck to both the window frame and the window panel easily.
With the air conditioner ready to go, we turned it on, set it to air conditioner mode, turned it down to 62 degrees, closed the bedroom door and left the room at a hot 89 degrees. Five minutes later, the entire apartment went dark as the circuit breaker had tripped. Apparently bedroom circuit breakers in our apartment building are 15 amps, and this air conditioner was not happy with the 15 amp breaker at all. As it turns out, the plugs in the dining room are on 20 amp breakers which are perfect for this air conditioner. We contacted Honeywell, an electrician, the apartment manager, and the apartment maintenance team and we were told that we could purchase an extension cord to use with this product. I had always heard/read that you SHOULD NOT use an extension cord with an air conditioner, apparently that's because people buy a low quality extension cord and plug in their air conditioner and it ruins the air conditioner. We purchased the recommended extension cord for $105, it is the Ridgid 50' 10/3 Heavy Duty Contractor Grade Indoor/Outdoor Extension Cord). We've had it plugged in ever since without any electrical problems.
We turned the air conditioner back on and the bedroom temperature was now 93 degrees. 2 and a half hour later, the bedroom was a cozy 68 degrees with an outdoor temperature of 109 and a living room temperature of 78 with a wall air conditioner. This air conditioner actually cools better than our wall air conditioner in the living room. In temperatures up to 118 degrees outside, this air conditioner keeps the bedroom a cozy 68-72 degrees when it's set to 62 degrees. In the winter time, this air conditioner keeps our bedroom 51-56 degrees which is perfect comforter weather and we run the air conditioner instead of the heater in the winter months. We love a cold apartment.
We run our air conditioner 24/7/365 at 62 degrees. It has increased our electric bill with SDG&E by $100 a month. It did not bump us into the next usage bracket, which is great since there are only two brackets now. The awesome thing about this air conditioner is that there is NO water to drain out, and no condensation build up on the air conditioner cabinet. They say in high humidity areas you may need to drain the water, but in our case (desert in Southern California) not only have we never had to drain it, but when you check the drain, it's bone dry. This unit will dehumidify up to 70 pints of water a day, so if the humidity in your room causes more water than that, you probably need a dehumidifier, or at the very least you'll have to drain the air conditioner.
In the winter months, the air conditioner created a new problem because it adds a significant amount of cool moisture to our bedroom. We have one of those weather station things which measures temperature, humidity, and so forth. The humidity in our bedroom jumped from 31% prior to owning this air conditioner to 86% after owning this air conditioner. My allergies noticed and I was coughing non stop. The towels in our bathroom smelled musty even after one use with leaving the bathroom fan on for a half an hour after showering. We ended up having to get a dehumidifier to run in our bedroom during the winter months. In the summer months, we usually do not have a problem. I say usually because the summer of 2017 has been the most humid desert summer that I ever recall.
In terms of noise, this is not a quiet air conditioner. In our last apartment we had a window air conditioner (which aren't allowed in our current complex) and it was much louder. If you don't like noise, you will notice this air conditioner while it's running. It comes in between 52-56 decibels, depending on when you measure it. When the compressor kicks on it's right at 59 decibels. I'm used to it now, but the first two nights, I would starter awake when the compressor kicked on. My significant other slept straight through it. We are used to running air conditioners and fans, so the extra noise was not a huge deal for us.
It comes with a remote control, which requires 2 AAA batteries, which aren't included. I am not a fan of the remote control. It's small, which in our house means you'll set it down and never see it again, and it doesn't bark like our RCA t.v. remote does when it's lost, laugh. The buttons are not back lit, so if you need to adjust the temperature in the middle of the night, you have to turn the light on, so you may as well just get out of bed and adjust it, which you can easily do in the dark. We never did figure out which side of the control panel the remote sensor was on, though we think it's the far right side. The remote struggled to work from 5' away and did not work at all from our bed which is 8' away from the unit.
6 days went by and the air conditioner started getting loud. It was a clattering or rattling noise. We came to learn that this sound means the filter is dirty. The filter is supposed to need cleaning every two weeks, but ours will only go 4-6 days depending on how dusty and dry it is outside. Summer 2017 has been both dusty and humid, which is rare for our area, and we are having to clean the filter every 3 days. Once you clean the filter, the air conditioner returns to it's normal running noise, which isn't quiet, but is not earth shattering either. We tried vacuuming the filter to no avail, it definitely needs to be rinsed off. We decided to buy an extra filter, which was $21.95 from Sylvane who sells Honeywell parts.
For almost a year, we had an always cool bedroom. We cleaned the air conditioner regularly, kept it dusted, changed the filter often, and the air conditioner happily cooled our bedroom. Fast forward to July 2017, a little bit before the one year warranty was up, and the hottest day on record in over a decade (120 degrees outside). At 1:30a.m. during a sound sleep we heard a thudding, spinning, thundering, blade ready to chop your head off, helicopter rotor type sound. It scared the living heck out of me, though I tried to ignore it, thinking it was a neighbor, because nothing we owned could make a sound like that. My significant other was not so optimistic got up, turned on the light, and realized the awful sound was our air conditioner. It was not only making really loud noises, but it was rattling our window, and we had to turn it off to avoid waking up the neighbors. A half hour later it was already 93 degrees in our bedroom (as opposed to 71 degrees when we went to bed) so we retreated with blankets and pillows to the couch and decided to troubleshoot it in the morning.
The next morning, we went through all of the troubleshooting tips and suggestions. We called Honeywell. We did not get any answers. I got on the Internet and found out that usually the noise comes from some type of broken blade. I thought that the company would send us a blade or something and we'd be good to go, but that was not the case at all. Apparently you don't just replace the blade, because it's in a complete housing, so I figured they would send us a new housing. I was wrong. I shot Honeywell an e-mail and didn't hear back for almost a week. Because we were in the middle of a bad heat wave, and we were spoiled by our bedroom a.c. I bit the bullet and ordered another one on Amazon, figuring the manufacturer warranty would take weeks to resolve.
Honeywell e-mailed us back 9 days later asking for photographs. Then said they were going to replace the unit and we needed to cut the cord off the unit and then take more photographs. To me, it would have been easier to replace the broken part, but that is apparently not how this manufacturer works. I expected them to ship out a replacement in 6-8 weeks, but to my surprise they shipped a replacement unit out the next morning (brand new, not refurbished) and it arrived a few days later. Before recycling the old unit we took it apart, there was in fact a broken blade, that looked like a fan blade inside, Google was right.
In the meantime, while waiting for Honeywell's response, the air conditioner from Amazon arrived. We set it up. All though it's the same model number, it is an updated version and instead of a single filter there are now 2 filters (one in the top at the back of the unit and one further down the back of the unit). We set it up and our replacement from Honeywell arrived 2 days later because there was a shipping delay with Amazon, go figure! Since we'd already been using the Amazon one, we decided to keep them both so we'd have a spare. We are also contemplating moving soon, and having 2, one for a second bedroom, would not be the end of the world. The timing was fantastic on Honeywell's part, one of the best manufacturer's that I have ever worked with, which is why I am only docking one star for the problem. Incidentally, the new unit from Honeywell also has 2 filters, so I believe that is the updated new design, with the same model number, despite the Amazon description still reflecting the older model.
I'm optimistic that our first unit was a lemon, and that now we won't have any problems, or maybe I just want that to be the case. The price on the unit varies greatly, the first time we paid $419, the second time we paid $499. Of course, both purchases were in the middle of summer during a heat wave. Of course air conditioners never break in the winter time, only during a heat wave, or at least that's been our experience. We love our air conditioner, except for the filters, which are a pain in the neck, and if left uncleaned cause the unit to be significantly louder. We have a couple of extras, rinse them once a week, let them dry, and just pop a new one in when the old one is dirty. Just make sure the filter is dry first! We are loving the cool sleeping weather even during the hot summer months.
1) it doesn't have an energy saving feature like many window units. The fan will constantly run. This isn't the worst thing, but I like to set my ACs to turn off when the room is cool enough. This unit's fan never shuts off (the compressor turns off tho)
2) I was planning to use this 50% of the time as a dehumidifier. I realized that no AC is as flexible as a dedicated dehumidifier - you can't set the point which it stops running. I think it cuts off at about 60% humidity.
3) Does not cool as well as a window unit - I knew this going into my first portable air conditioner, but I didn't realize how much it made a difference. To give you some data, I'm in my 170 sq foot bedroom. It took 2 hours to cool the room from 87 to 77. My window unit (with only 10000 BTU cooling) did this in one hour.
4) With the size of the exhaust pipe, it takes up a lot of floor space.
1) Easy to install
2) Rolls away for storage
3) I like how the condensate is expelled with the hot air
Overall - This unit is just fine. But if you are able to install, remove, and store a window unit every year, go with that and not a portable air conditioner.
