Customer Questions & Answers

Can this unit be exhaused through holes in the wall?

Asked by: Carpentersdaughter
Coming from an A/C professional, the discharge air is going to be much cooler than that of a dryer, and will not in any way pose a fire hazard during normal operation. The only hazard would come in a very rare situation where the unit itself catches fire with the fan continuing to run, expelling flames/hot air through the discharge hose. I would not worry about it for temporary/periodic use, but if this will be a permanent fixture then some fire-proofing may be appropriate

12,000 BTU Portable Air Conditioner with Dehumidifier, Heat and Remote is rated 3.7 out of 5 by 26.
Rated 5 out of 5 by from Great Unit Works great for cooling! Cools down my 700sqft TV room quickly. Noise level is better than most. Installation is pretty much a snap, I did have to trim the window sliders to fit the narrow window I installed the unit in, but that is something I expected. A good sharp utility knife worked well..I haven't had the unit long enough to use the heater yet, so I can't comment on that area. Does kind of look like a mini fridge though, to bad there's no place to put beer in it! That would almost make it perfect for me! Oh and it's not as big as I though it would be. I like the fact that as It cools down the room the fan speed drops along with the temp making the noise level drop as well. I'd buy another if I needed it. Longevity of the unit is something that remains to be seen. Came well very well packed.

Rated 5 out of 5 by from Great unit Our third floor in our townhouse was so uncomfortably hot in the summer and cold in the winter. Heat and cool works great. It's not very loud. I read several reviews and this one seemed to get the best overall with the fewest amount of complaints. Install was a snap, in fact my 20 y/o daughter set it up in her room by herself if that gives you any indication of how easy it is. The exhaust fitter unit is great. I can't comment on the dehumidifier as we haven't had a need to use that yet.

Rated 5 out of 5 by from Perfect for my application I purchased this unit to convert my garage into an embroidery studio. The unit easily vented through the garage door and disconnects if and when I need to open the door. It cooled the space down in about 10-15 minutes when the front of the garage was in the direct late afternoon sun. Its no more noisy than a regular AC window unit when it is on full fan. The lower fan setting is hardly noticeable. Haven't had to use the heat function yet but I am encouraged that it will be equally as efficient. I am thrilled with it so far.

Rated 4 out of 5 by from Cools very well, would recommend Not perfect, but definitely a keeper.This Whynter air conditioner is by far one of the better air conditioners I've used over the last 10 years. We no longer use central air except when there are guests. Spot coolers like this save a considerable amount of energy. It's bigger than a window air conditioner but portables are by far easier products to use. Don't try carrying this by yourself, it's easily over 50lbs. Not sure how BTUs are work but this does better than assumed.

Rated 4 out of 5 by from A very nice unit I bought this unit to keep my garage at a reasonable temperature (89) in the summer and to be a backup in case something goes wrong with my house AC. As luck would have it, my home AC went out a week after I received this. I was able to cool down my bedroom very nicely with this unit so I could at least sleep comfortably. My only complaint is that it doesn't remove much humidity, but that seems to be the case with all portable or window units I have used. The unit is also very quiet. If you have a brick home or a home where you actually have a window sill the majority of portable AC units WILL NOT work for you since most use a round to oval adapter for the exhaust plate in your window. This design is never done properly, you can't insert the adapter in the window plate because it hits the sill. This unit is one of the few that has a round intake/exhaust vents so it works as it should. Install was a breeze, the pieces fit together perfectly and to get a solid seal on the window/frame I just used self-adhesive foam strips (Home Depot carries this in the door hardware isle). Easily removed and any residue will be in the window track, not all over the frame like the suggested duct-tape. I have a feeling that most complaints about this unit relate to them not leaving the unit upright for 24 hours after receiving it. You MUST do this if you want the unit to last, it is very important. I am only giving it 4 stars because I have used it for such a short time period (2 weeks), I have no complaints so far.

Rated 5 out of 5 by from It cools the house wonderfully. I recently bought new windows and we didn't want a window unit to damage them in any way so we looked for a portable air conditioner. At first we bought a Soleus Air Conditioner/Heater 13,000 BTU and it did not even cool our living room. So, I researched other portable air conditioners and found that reviews reflected that dual hoses work better for cooling then the single hose units. I found Whynter and read all the reviews I found on it and it sounded like a great deal with a great air conditioner. It is. It has cooled my living room, kitchen, even hallway, and bathroom which the window unit did not. I would recommend this highly. The only negative is that it look like a tiny refrigerator in my living room. The hoses are a bit bulky. And the vent on the top of the machine does not have valves to slide left to right or oscillate. Other then that and as people said on other reviews the instructions and remote are not obvious as others are. But, overall I would highly recommend it for its cooling capacity. I don't know about the heating yet....I plan to use it for my sunroom in the winter.

Rated 5 out of 5 by from Easy to operate. I ordered the unit at my local sore and it was delivered when promised. I was able to install the unit myself without help from my husband. The directions were clear and easy to follow. I got the unit just before a CT heat wave and it is working as discribed and promised. I have every reason to believe it will heat in the winter as well as it is cooling in the summer. Over all this has been a good experience for us.
