If there are two windows in a large room would two 6000 BTU window units cool the same as one 12000 BTU window unit?

I am not an expert on the mather, but in my opinion, I would say yes.
Here is why: (and provided that the windows are on two different walls and preferably on oposite walls)
a) You have a better air circulation so that the temperature is more uniform;
b) You will be able to run your air at low fan speed while the would be at high
c) You should have a better desehumidifaction factor
d) It should increase your CFM
Note; Whether you use 2x6000 or 1x12000 on the same wall then I would suggest to use a fan at the oposite wall to recirculate the air.

AnswerActually two would be less energy efficient. You would have to have some sort of temperature measuring device that is independent of both that also has the capability of engaging both units at the same time or seperately because of different 'hot' or 'cold' spots in the room effecting each a/c unit differently. Most a/c window units smaller that 12,000btu do not shut off when not actually cooling the room. The compressor may shut down but the elements that control the fan motor allow the fan to continue running. This is not cost efficient. Most 12,000btu and larger units completely turn off when not cooling. This is because the unit actually cools the air to just a few degrees cooler than necessary to deactivate the unit. Once the cooled air coming in contact with the unit's sensor reaches a certain temperature the unit comes back on. I have a 12,500btu unit that keeps my entire downstairs nice during the cooling season and it turns competely off. It was purchased from Montgomery/Ward and has been in use for over 20 years. I personally built a sealed inclosure around the window housing that the actual cooling unit is in. Try to find one like this. When the front cover is snapped out there is a strap handle that allows the cooling unit to slide out of the outer casement. I simply let it set on a table and clean and service it just about every year.Wiki User

Is it better to have multiple small window units or one large window unit when trying to cool one floor of a house that doesn't have good air flow?
It is better to have small multiple window units than one large window unit when trying to cool one floor of a house that does not have good air. This way, air flow can be controlled in accordance to needs at any given time.
How do you store window AC units, during the winter?
The easiest way to cool an older home that heated with radiators, is to use window AC units. Storing these window AC units during the winter can be a lot of work. What is are some suggestions for properly storing window AC units during the winter?
What do you call an interior wall window?
As far as I know, there is no specific name for it. Windows installed in interior walls are rare, but do exist. They are most commonly found in office buildings. Although "interior wall window" seems wordy, I would refrain from using the phrase "interior window". An interior window refers to the interior portion of an exterior opening which has two separate window units as with storm windows. The correct terminology is " borrowed light", and a light over a door is a "transom light"
What would be the best units to measure the area of a window or windows so you can buy the correct size of curtains?
Metres and centimetres. Or feet and inches. Then square any measurements to find the area.
What are the basic air conditioner units?
The basic air conditioning units are either wall, window, portable or central units. Window units are placed in the window, wall units are installed in the wall, portable ones are usually powered with electricity and can be moved wherever needed. Central air conditioning units can cool an entire house instead of just one small area.
Do you have to use a mobile home air condition unit in a mobile home?
No, you don't . I have neighbours with all kinds of air conditioners in their mobiles. Some have simple window units, some have rolling units that can move room to room and some even have large units on the roof.

How many btu in one cubic meter?
Btu and cubic meter are two different measuring units. Btu is the unit for heat transmission, like in ac units 12000 btu/hr. It means this ac unit would remove 12000 btu of heat from the room in one hour. where as cubic meter is the unit for volume.
What is the difference between a 10000 and 12000 btu air conditioner?
A wise guy would say "the difference is 2,000 btus" , but I'm not a wise guy. If you're looking at window units, the answer is "there's not really much difference". 12,000 btus equals one ton of cooling capacity and according to an old rule of thumb will cool approximately 400 to 600 square feet of area, depending on your geographical area, insulation, type of windows, air infiltration, etc. If you have a large area to cool and it's an older structure, you might want to consider using the mini-split sytems on the market today.
