Whynter 12K BTU Portable Air Conditioner

We bought this for a 10'x10' bedroom filled with electronics equipment that keep the room overheated year-round. My son wanted the portable unit, rather than having to bring his heavy, noisy window A/C up from the basement for those unseasonably warm spring and fall days outside of full time A/C weather. He also wanted to be able to use the fan and dehumidifier, without having extra appliances in his room. The heat from the electronics concern me, and the stuffiness cannot be good for a teenager with allergies, so I wanted my son to have a fan on year-round to keep him cool and to help the equipment stay cooler. This portable A/C seems to fit all of our needs! When the A/C is not in use, there is a cap that fits over the vent hole on the window kit, so it's easy to detach the vent tube and leave the kit in place when the fan or dehumidifier are being used (neither require the outside vent).The unit is sleek and modern-looking, The vent hose and window kit were easy for me to assemble in about 15 minutes. The only thing needed is a Philips head screwdriver to tighten the hose to the window kit, and to tighten the screws to the window frame, if desired. One thing that was necessary to add which was not contained in the kit: 4 nuts to go behind the 4 vent screws; otherwise the hose pops off every time you move the unit. No big deal, though.In terms of how the 3 functions operate: 1. The A/C is excellent! It starts bringing the room down by one degree during the first minute of turning it on, and continues till it reaches your preferred temperature setting. The vent hose got fairly warm when the A/C was put on high in a hot room, but as the room reached a cooler temperature, the vent became cooler, as well. We checked the plug during this time, and it remained completely cool throughout. 2. The dehumidifier has easy to empty water collection pans. We haven't tried this function yet, but living on Long Island, I'm sure we will use it over the course of the humid summers here, and will add an update if there is any problem to report. 3. The fan is excellent at all three settings, and is basically silent on low. Even on high, it is decent white noise and not offensive, providing significant air flow throughout the room.There are several items that I would have liked in the description prior to making this purchase, since I would have measured the space and planned accordingly. The directions say that 1. for safety reasons, you need 20' of empty space surrounding the unit, and not to place it near a wall or corner, which could interfere with the intake/air flow. (We have it sitting only 3' from the back wall, facing into the room, and all is well. It cannot get knocked over where it is, and we do not have young children in the house, so it is safe there, and air flow appears fine.) 2. The power cord is 6.5'. For safety reasons, you cannot use an extension cord or electronics multi-plug, since it would disable the overheat/surge safety mechanism in the plug. 3. They said to plug this unit into its own circuit, to avoid tripping a circuit breaker during operation. 4. Although the vent hose is 9' long, and they sell extension vent tubes, for the air conditioner to perform optimally, they highly recommend using the shortest possible length of venting tube. (We have the vent tube extended only 39"; there is an "S" curve from the window to the unit, since the vent drops down from the window kit and fits into the unit about halfway down.) Since we have an old house, we only have one 3-prong plug near my son's windows; luckily for us, it is on its own circuit breaker. If I had known the length of the power cord (which barely fit), the safety issues preventing use of an extension cord, the footprint needed around the unit, the length of vent hose that works best, the need for an isolated circuit breaker, etc. I would have taken all of those issues into consideration and measured before making this purchase. As it turned out, we got lucky, but it would have been very disappointing to receive the unit only to find out in the middle of installation that we couldn't meet the specs they call for. I don't usually write long reviews, but as I got to each installation step, I found another hurdle and wondered whether we would be able to keep the unit. If those spec's had been included in the description, it would have made installation an easy and stress-free experience.If this portable A/C fits your space using their spec's, I'm sure you will be thrilled with its performance! We are! I hope you find this review helpful!
