Basic Design and Specs

The case of the Honeywell MN12CES makes it one of the more stylish portable air conditioners around. And, at 29.3″ high x 18.1″ deep x 15.2″ wide, you wouldn’t have trouble finding space for it. However, with a hose length of just shy of four feet (47 inches), you won’t have much choice about where to put it, either.

With an exhaust hose this short the only reason to have casters on the unit is for those occasional moves to another room. However, you have only one window kit (unless you buy or rig another). So, instead of “occasional” I should probably have written “rare”. Fortunately, as a single hose design, re-doing the installation is pretty easy if it comes to that.

The noise level is a very livable 55 dB. That’s par for the course. You’re unlikely to find a mid-range unit that’s much quieter. It’s definitely noticeable but much like the background white noise you would expect. You should have no trouble hearing the TV in the bedroom over it, provided the unit isn’t too close to the bed.

The unit also houses an air filter, a common feature these days. Like so many others, it doesn’t do the job of a real air purifier but it helps keep down the dust level in the exhaust. It’s recommended you clean it every couple of weeks but that depends, of course, on your environment. When necessary, it’s pretty easy to remove and replace.

Cooling Power

There’s one other oddity about the MN12CES besides the short hose. The Maximum Operating Temperature is rated as 100º F (37.8 C). I don’t know what life is like at your house but the weather around mine can be far hotter than that. Of course, you generally expect it to be cooler inside but not if you’ve just come home from a long weekend trip, just to name one reasonable scenario. I’m hoping Honeywell is being very conservative here.

It’s particularly odd in view of this Honeywell’s cooling power: 12,000 BTU. That’s not their top-of-the-line rating but it will normally be ample for the room area it’s designed to cover: up to 400 square feet. It may not do the job in a very large living room especially if you have a cathedral ceiling but it should be just fine for a good-sized home office, even one packed with computer gear. It actually performs better than you’d expect for such a modest rating.

Fortunately as well, the MN12CES doesn’t draw an outrageous amount of power. You might notice a bump in the electric bill if you run it all day but, at 1100 watts, it’s well below some other units in this same niche, such as the Koldfront Ultracool PAC1401W. On the other hand, that model is rated at 14,000 BTU and covers a larger area (500 square feet). It’s always a tradeoff.

Dehumidifying Capacity

If you live in a very humid zone the MN12CES should keep up on all but the most extreme days; it can dehumidify up to 70 pints per day without any action on your part. Other than, that is, setting it appropriately.

Typically, it will blow that moisture out the exhaust hose. Only rarely do you need to concern yourself with drainage. When you do, there are two drain plugs. One is a fitting for a thin hose you can direct outdoors. The lower one is intended for a shallow pan that, thankfully, is only a last resort in most cases.

Control Panel

The cooling power is modest and the control panel follows the same theme. This model offers a simple touch panel. The company can call it a touch screen but it isn’t like a contemporary smartphone or tablet.

Also, one could wish it offered something a little better than the usual up/down arrows for changing the temperature. If you have only a few degrees to go that’s not bad but few users want to tap and tap and tap to go up or down even as few as 10 steps. That admittedly minor complaint aside, the MN12CES controls are all very responsive.

The number and type of settings here won’t dazzle a technophile. Mostly, they provide for the usual Mode change (Fan, Cool, or Dehumidify), fan speed, temperature, and display change. The display doesn’t offer too much of interest – chiefly temperature and timer – but it’s clear enough and won’t likely annoy anyone who uses this in the bedroom at night.

The timer is a bit of a disappointment – unfortunately common in mid-range portable air conditioners. You can set the number of hours to operate (from 1-24) but not specific times to start and/or stop.

Remote Control

There is a remote control to set/change those settings but it, too, is underwhelming. It certainly covers the gamut – Mode, Fan Speed (High, Medium, or Low), Timer, and Temp. But, like the panel itself, you have to make a lot of taps to get very far from the current settings.

Worse, it seems not very sensitive. Many times it required more than one tap to actually make a change. That might be explained by limited range or blockage if there were anything between the remote and the unit but that’s not the case here.
