This will cool a small room. Will not cool a whole house. You will need to leave the door closed to get it really cooled.\It will cool my bedroom 16x14 with the door closed and not turning it off. Hope that helps.

It will cool up to a 400sq. ft. room, which is not at all very big. This unit is horrible and do not make the mistake of buying it. It simply does not cool.

The product description says 400 sq. ft. (standard ceiling height being about 8 ft)

According to the Air King website the rating is: 2470 / 1700 / 1360. I open 3-4 windows part way and set it to exhaust (instead of intake) and it very effectively cools approximately 1400 sq. ft. overnight.

I have cathedral ceilings so its tough to gage how well its living up to its claim, it does do a pretty good job of heating one floor of 1200 sq ft w cathedral ceilings, also alot quieter than ones ive had in the past. With shorter ceilings I believe it would do much better for you.

it will cool 500 sq ft. saying the temp outside is over 95 degrees. 1000 sq ft is way too much for any window type that is 110v

That would depend on the outside temperature, height of the ceiling and thickness of home insulation. I turn on air-conditioning when it's 84F outside, so I haven't experimented with heating any room to that temperature, however I can get my similar-sized room with a 12-ft. ceiling (at the peak) up to 70F on a chilly day. I wouldn't want to use these heaters as a main heat source under extreme conditions--at least not for long, and use mine as back-up assistance to our LP gas furnace in winter as well as for taking the chill off on cold spring or fall mornings.

Could not say for sure but a couple of comments to possibly make it more effective. if you could possibly hang the unit well down from the 20 foot ceiling and position equipment that generates significant dust in closer proximity that should compensate for the large space. I have not put my unit to the test so far to give you a better feel for cleaning capacity but my 13 X 14 shop opens up to a basement storage area o that would make it a similar size to a 27X27 with about a 9 ft ceiling. So far I have not noticed any excessive dust in the storage area but again i have not really pushed it enough to be conclusive.

Same square footage as yours. This heater puts out only a mild heat that will dissipate quickly in bigger rooms, with possibly large or multiple windows. The smaller the space the better it works. It struggled to keep up a satisfactory temp in a space the size of ours. High ceilings probably didn't help my situation either. I placed mine in a bit smaller room and it works wonderfully.

Not sure on how large maximum (you'll probably want some online tool for that), but my room is about 13 x 16 x 9 ft and this unit does a solid job cooling it.

Our home is 1400 square feet and it's just right. I think the larger unit would be too much. This one could probably go up to 1500. We have 4 of the 1/2 round roof vents and 2 of the ~12x16 dormer vents - that's more than enough to vent the air out the roof. You'll also notice secondary cooling because the attic get's aired-out. The noise isn't bad - of course that's subjective. Anyway, we have no central air and when it cools off outside at night, the fan cools the whole house very quickly. During moderate days, it keeps a freshing breeze throughout.

700-800 sq. ft. Heats that size area very well on low. Can't turn higher cause it gets too warm in the room !

If you could define "small" in square feet this would be a much easier question to answer. If you live in an apartment complex or have a small condo, yes it should cool a small bedroom (200-300sqft) easily.

My attic is 1000 sq ft. The twenty watt unit has made a significant in oir ability to cool our upstairs, we no longer feel heat radiating from our ceiling. If the surface area of your attic is 1700 sq ft i would install two attic fans

I sure hope so. The humidifier specs say it is good for up to a 700 square foot room. Such a room with a one foot ceiling height would have 700 cubic feet volume. More typical ceiling heights are 7, 8, or even 10 feet. Those ceiling heights would be 4900 cubic feet, 5600 cubic feet, and 7000 cubic feet respectively.

20" is the highest point. If you have 8' standard ceiling height you will be fine.

I am not sure - we have a newly built 14x16 ft. three season room and live in the Midwest. This past winter we used it to see how warm it would get the room and it seemed that whatever the room temp was the fan raised it by about 10 degrees, so we were happy. But we also invested in insulated windows and door in the initial build too. Hope this helps!

I use this unit in attic space with little insulation which is roughly 300 sq ft. On very hot humid days it can bring temps in room to mid 70s.
