Review: Whynter 12,000BTU Dual Hose Portable Air Conditioner, Frost White (ARC-12SDH) - After extensive research, reading customer reviews, professional reviews and pricing at my local appliance stores, I broke down and bought two of these units, 2 weeks apart. My son and I moved in with the elderly 'rents to look after them. They keep the central AC at 80 and watch TV with wool caps, slippers and lap blankets... yes, in the middle of the Florida summer! To say the least my son and I were sweatin' it out at night. I got only one portable AC (PAC) at first because of some of the negative reviews, large investment on something I wasn't too sure was going to work well for us, problems with the drainage, etc... I didn't want to invest in two, if one didn't work. The room I am cooling is approx. 12x 12. I probably got too much in the BTU department, but I wanted to be sure that it would do the job. It ABSOLUTELY DOES THE JOB AND THEN SOME! I did get the second one. The PAC came in a large box, packaged well. Easy to disassemble, box was taken away by recycling. All good. My brother-in-law set the PAC in my bedroom. I only have a sliding glass door to work with, so he needed to do some modifications and adjustments. All of the parts were in the box and easily assembled. Follow the directions (and pictures) and all should match up well. I went to Home Depot, purchased a 4' x 8' piece of AC insulation board (foam in the middle and covered with silver foil on the outside...cuts easily with a utility knife), a roll of AC duct tape (not duct tape, but the kind that is foil and used for AC duct work), 2 packages of 1" x 1" foam weather stripping, and 3 feet of 1/2" diameter tubing. ($30-$40 all together). The tools that my brother in law used were a drill to make a 1/2 inch hole in the insulation board, a utility knife, and a measuring tape. I'll tell you how he put it together and the reasons for doing it the way he did... after all, he is a clever guy and he saw a design flaw here or there... First, he measured how wide he would need the insulation board to be. Remember, it went into a sliding glass door, which would render the slider useless, once the PAC was installed. (I didn't care, I NEEDED the AC). He cut the insulation board 4" wider than the width of the plastic window kit (comes with the unit, has 2 holes to attach the duct hoses). Of course, the height of this piece has to fit into the door. Next, he decided where he wanted to put the plastic window kit in the insulation board. He centered the plastic window kit vertically and pressed it into the insulation board to leave an imprint in the board. He used the utility knife, followed the straight lines of the impression, to cut out the shape of the plastic window kit. He used the AC duct tape to tape the window kit into the insulation board, front and back. He next taped this, (the piece of insulation board with the plastic window kit taped into it) into place in the door jamb/frame of the slider. All taped in. It doesn't look pretty, or it looks as good as it can for being what it is, but it certainly is functional. He then attached the exhaust hose to one of the round circles (4" hole on the plastic window kit) and put one of the caps (provided) on the other. ***HERE IS WHERE HE THINKS THERE IS A DESIGN FLAW, AND WHY HE DID NOT ATTACH THE SECOND HOSE TO THE SECOND HOLE. The directions and the whole idea of the DUAL HOSE SYSTEM is to blow out the hot exhaust through one of the hoses and then to draw in cool air, from outside, through the other hose. This is the problem with this idea (according to my brother in law): "THE TWO HOSES, WHEN CONNECTED TO THE WINDOW KIT, ARE ONLY 1 1/2"-2 " APART. HE DOESN'T BELIEVE IT'S POSSIBLE TO DRAW IN "COOL" AIR FROM THE OUTSIDE FOR TWO REASONS: IT'S HOT OUTSIDE, HENCE THE NEED OF THE AC AND BECAUSE THE INTAKE IS GOING TO 'SUCK' THE HOT AIR IN FROM THE EXHAUST BECAUSE IT'S TOO CLOSE TO THE INTAKE." So, the intake hose is attached to the unit, but not to the vent hole. It's simply leaning up against the door, out of the way, sucking in the cooled air from inside the room. When I explained what I was doing to the Home Depot guy, he reminded me that once that sliding glass door was opened a few inches, there would be a gap between the two doors... in the middle, if you will. Simple solution was to stuff the foam weather stripping in there! Done. I was concerned about the drainage issues... Florida is HUMID! I read on some reviews that the unit would shut down in the middle of the night because the drip pan was full... Again, my brother in law to the rescue!!! He removed the plug, drilled a hole in the insulation board at the same level or height of the drain. He attached the tubing to the drain on the unit, and threaded it out through the insulation board to the outside. Problem solved! After he installed the unit, I noticed that there were tiny little gaps in the plastic window kit, around the circles... I could see light shining through. I ran a bead of caulk around it. No more light, no air escaping and no ants getting in. I turn the PAC off when I'm not home. Remember, the central AC is set at 80 degrees and the outside temperature, at this time of year, during the day is between 90 and 95. When I return, I turn the PAC on and set it at 74. Within 15 minutes, the room is cooled down to 74. (I have a separate thermometer and wanted to make sure that it was cooling to what I had it set at.) As I type right now, my fingers and toes are cold! I'm comfortable... I might even have to turn it a little warmer! Some reviews mentioned that it is a loud unit.... I don't agree... it is no louder than a window shaker! I would definitely recommend this unit. So far, so good! It's only been three weeks, but I am optimistic that it will continue to work well. (I waited 10 days or so to order one for my son and he, too, is now comfortable in his room. It's about the same size as mine.)
Review: ARC-131GD comparison to ARC-12SD - I have been using this for about 2 weeks. I bought this for my master bedroom which is about 23x16 (368 square feet) and has vaulted ceilings. It was to replace a Whynter ARC-12SD which was working great but was going to be moved to my wife's office. Not to make this a review about the ARC-12SD but comparing it to the ARC-131GD reveals the latter's pros and cons. The ARC-12SD has been in use for about 1.5 years and has performed great. It had two downsides. Its first downside may not be a downside depending on the room you place it in. It has a bright blue led display and several other led indicators that could not be turned off. At night, in a bedroom, the led's are quite bright. We taped a credit card over the main display. The card blocked most of the light at night and we could flip it up if we wanted to see it if we wanted. The ARC-131GD has a remote control that contains the display rather than having it on the air conditioner itself. My wife and I both like that. There is a spot on the unit to store the remote but my wife keeps it on the nightstand. The ARC-131GD does have a blue led on the front of the unit but you can turn it off. Again, depending on the room you are putting this in, either may work for you. We only realized the ARC-12SD's second downside when we started to use the ARC-131GD, The ARC-131GD is quieter than the ARC-12SD. The compressor seems to quietly engage in the ARC131GD whereas the compressor on the ARC-12SD seems to be more abrupt and noisier. Although I do remember hearing the ARC-12SD cycling at times (I guess it woke me up), I have not noticed the ARC-131GD cycling at night (I guess it does not wake me up). On paper, the ARC-131GD is ever so slightly better suited for a larger room. The ARC-12SD is rated for 400 square feet while the ARC-131GD is rated for 420 square feet. After reading a few reviews it seemed like the ARC-131GD was slightly more efficient than the ARC-12SD. Believing that the ARC-131GD was more powerful and more efficient lead me to consider the ARC-131GD rather than just getting another ARC-12SD. Price wise, it seems that the ARC131-DG is generally available at a lower price than the ARC-12SD. When the ARC-131GD dropped to a particularly low price, I jumped on it. The first night with the ARC-131GD revealed just how quite it is. Of course you can hear the fan, similar to, but slightly quieter than the ARC-12SD's fan. From a cooling perspective, the ARC-12SD cooled the room faster. Not sure why this is but...every night the ARC-131GD is slower to cool then the ARC-12SD. Both were set to maximum fan speed. During the night, both cooled the room fine. Neither my wife nor I have been uncomfortable. We both notice the room cooling slower with the ARC-131GD as compared to the ARC-12SD. The ARC-12SD does have adjustable vents while the ARC-131GD does not. We used to point the vents on the ARC-12SD as high as they would go, almost vertical. Since hot air rises, it seemed like a good idea to push the cold air towards the ceiling. The ARC-131GD pushes the air out at a more horizontal angle. Maybe if it could push the cold air towards the ceiling, it would do an better job at cooling the overall room faster. This may only be an issue with a room with a vaulted ceiling. Would I buy another ARC-131GD? Based on the price I got it for (much less than the ARC-12SD) I would say yes. How much am I saving in electricity using the ARC-131GD in comparison to the ARC-12SD? If your requirements are for the room to be cooled a bit more quickly than the ARC-12SD may be better choice. If you have to run the ARC-131GD 20 minutes longer a day to get the room to a specific temperature, does its slightly better efficiency pay off? If the ARC-131GD is priced the same as the ARC-12SD, I would get the ARC-12SD. If the ARC-131GD is at an all time low price-wise, I would get the ARC-131GD again. It has its pluses and minus's (both of which depend on where it will be located and your personal preferences). A couple of additional points. The ARC-12SD has an intake and exhaust hose. Both are the same diameter. The ARC-131GD intake hose is the standard size. The exhaust hose is smaller. The connectors are standard as far as connecting to the air conditioner or window vent but the tube connections are different sizes to match the hoses. The tube lengths on the ARC-131GD are about 8 inches shorter than the ARC-12SD. Whereas I could maneuver the ARC-12SD away from the window and point it an any direction I wanted, the limited hose length on the ARC-131SD did not allow for this. I had to place the air conditioner as close to the wall as I could. Although I had standard replacement hoses which were longer, I could not utilize them because of the non-standard exhaust hose connector of the ARC-131GD. My solution, buy 2 more standard connectors. I live in FL. My back yard, which is where the air conditioner cooling intake pulls air in from, is basically a jungle. The air being pulled in is extremely humid. When I hooked up the new air conditioner, I replaced both the intake and exhaust tubes. The intake hose I was replacing was full of a very light coating of mildew. Yuck! Even given those conditions, I never had a problem with the ARC-12SD filling up with water. I have read other reviews of the ARC-131GD and some have reported problems with the unit filling with water. So far (2 weeks) I have not had a problem with the unit filling with water even with the very high humidity.

### ⭐⭐⭐⭐⭐ Whynter 12,000BTU Dual Hose Portable Air Conditioner, Frost White (ARC-12SDH)
*by F***L on September 3, 2012*

My son and I moved in with the elderly 'rents to look after them. They keep the central AC at 80 and watch TV with wool caps, slippers and lap blankets... yes, in the middle of the Florida summer!

Maybe if it could push the cold air towards the ceiling, it would do an better job at cooling the overall room faster. This may only be an issue with a room with a vaulted ceiling. Would I buy another ARC-131GD? Based on the price I got it for (much less than the ARC-12SD) I would say yes. How much am I saving in electricity using the ARC-131GD in comparison to the ARC-12SD? If your requirements are for the room to be cooled a bit more quickly than the ARC-12SD may be better choice. If you have to run the ARC-131GD 20 minutes longer a day to get the room to a specific temperature, does its slightly better efficiency pay off? If the ARC-131GD is priced the same as the ARC-12SD, I would get the ARC-12SD. If the ARC-131GD is at an all time low price-wise, I would get the ARC-131GD again. It has its pluses and minus's (both of which depend on where it will be located and your personal preferences). A couple of additional points. The ARC-12SD has an intake and exhaust hose. Both are the same diameter. The ARC-131GD intake hose is the standard size. The exhaust hose is smaller. The connectors are standard as far as connecting to the air conditioner or window vent but the tube connections are different sizes to match the hoses. The tube lengths on the ARC-131GD are about 8 inches shorter than the ARC-12SD. Whereas I could maneuver the ARC-12SD away from the window and point it an any direction I wanted, the limited hose length on the ARC-131SD did not allow for this. I had to place the air conditioner as close to the wall as I could. Although I had standard replacement hoses which were longer, I could not utilize them because of the non-standard exhaust hose connector of the ARC-131GD. My solution, buy 2 more standard connectors. I live in FL. My back yard, which is where the air conditioner cooling intake pulls air in from, is basically a jungle. The air being pulled in is extremely humid. When I hooked up the new air conditioner, I replaced both the intake and exhaust tubes. The intake hose I was replacing was full of a very light coating of mildew. Yuck! Even given those conditions, I never had a problem with the ARC-12SD filling up with water. I have read other reviews of the ARC-131GD and some have reported problems with the unit filling with water. So far (2 weeks) I have not had a problem with the unit filling with water even with the very high humidity.

### ⭐⭐⭐⭐⭐ You really want a dual hose air conditioner.
*by T***S on July 2, 2015*

I live in a southern California where 10 months a year, it's pretty nice. But I also live a bit inland, so about two months a year it gets unbearably hot. I was toying with doing a whole house air conditioner (3-ton, aka 36000 btu/hr), but the bit for doing it up to code was well past ten g's. So I started to research alternatives. Since I have sliding windows, I really couldn't use a window air conditioner. There are casement air conditioners sized to fit sliding windows, but the selection isn't as good. I wasn't really considering a portable air conditioner because I only knew about single hose units and there were too many drawbacks. The idea of a single vent portable air conditioner is pretty attractive until you consider the thermodynamics of it: all of the heat producing parts are in your house -- which means that you have to cool them too. And even though the gets vented to the outside, that air has to come from somewhere... like that precious cool air that you just made. And all that air being blown out the window has to be replaced, which means hot air is being sucked into your cool room under the doors and through various air leaks. In short, while you're trying to cool the room you're fighting against the heat from the compressor, the cold air you're throwing away, and the hot air that's being sucked in. A single hose air conditioner is the worst way to cool a room short of leaving your refrigerator door open. *** That's why you *want* a dual hose air conditioner. It solves two of the three big limitations of single hose portable air conditioners: it uses outside air for the condenser (hot side) core airflow, so it doesn't waste your just cooled air, and it isn't replacing that cooled air with hot air. The hot side stays hot and the cool side stays cool. Sure that pesky compressor is still getting hot, but the only way you're going to solve that is to buy a window air conditioner. So, needless to say I'm quite happy with my purchase. It gives me 1/3 of the cooling of a whole house AC, for less than 1/10 the cost. Granted I can only cool one room at a time, but this means being able to get a good night's sleep rather than being miserable two months a year. One other technical things I'd like to talk about: drainage. The act of cooling will draw moisture from the air. This unit gives you two options to get rid of it. For low humidity climates, it is designed to drip to a pan at the bottom of the unit. As the hot-side air is drawn over it, the water will evaporate again, pass over the condenser (hot side) coils and be vented to the outside. You *want* this to happen: moisture laden air holds more heat than dry air, and will pull more heat out of the hot side coils. Thus letting the moisture fall to the drip pan at the bottom and evaporate again will cool more efficiently than if you drained it off and let dry air pass over the hot side coils. However, if too much condensed water accumulates in the drip pan, a float switch shuts off the compressor. Which happens in humid weather. For mid/high humidity areas, there is a drain port halfway up the unit with a garden hose fitting. There is already plenty of water vapor in the air for heat transfer: no more is needed in the drip pan. Thus you should just drain it: I took a hose fitting and a meter of clear plastic tubing and ran the drain output into a glass jug (see attached photo). In two evening's use, I got about 1.5 gallons out of it. (See other attached photo) That's almost 6 liters of water that was in the air making things muggy. I was amazed over how much water came out of the unit. The remote is pretty nice. I can leave it on the nightstand and turn on/off the unit without getting out of bed. One more thing, this particular model is also a heater (actually a heat pump). It can warm your room in winter, providing the outside air is above 45 deg F. It won't work as a heater in Minnesota, but can be used on southern California winter days to take the chill out of a room and where the whole house furnace would be overkill. Now to deal with some of the objections I've seen in other reviews: 1. Size. It's 12000 BTU/hr, that's bigger than many/most air conditioners, but it is not enough to cool your entire house. It does make 200 sqft into a meat locker though. Most would agree that it should adequately cool 400-550 sqft. 2. Noise. Now that we're all used to whole house AC and climate controlled offices and cars -- where all the moving parts are tucked out of the way -- we forget that all that equipment makes noise. It's not quiet/silent, but it's not too loud either. I usually run mine about 3 hours before bedtime and turn it off. There is a timer so you can run it for an hour or two after you turn in. Even if I had to run it all night, I'd rather sleep with the fan and compressor noise rather than tossing and turning and not sleeping from the heat. 3. Water/dampness. There were a lot of complaints about the unit stopped working in humid weather. That's because the condensate could accumulate in the drip pan and the limit switch would shut off the compressor. The solution would be to drain the moisture from the upper drain port. The second water complaint was that the unit would leave a puddle on the floor. Again the same thing. The drip pan is just that: a pan. If you tip the unit, water will spill. (Don't ask how I found that out.) If you're not on a level surface, you may be spilling before the limit switch shuts off. If you have that much water production, maybe you should be using the upper drain instead. 4. Lights. This would be *MY* biggest complaint. They're pretty bright. In fact they keep me up at night more than the noise. Worse yet, there are no labels explaining what they mean. Which means RTFM if you're wondering what the purple LED means vs the blue one or green one. And you have no idea what the fan speed is or other indicator lights because they're all blue, just different positions for different settings. Not quite enough to drop my rating from 5 stars to 4, but close.
