How to Calculate Your Room Cooling Needs

If you cannot get your house cool when the sultry summer sends its death rays down each year, the problem may not necessarily be that your air conditioner can appropriately be compared to a piece of fecal matter. The problem may simply be that your air conditioning unit does not have the kachongas necessary to do the job. What you are looking for is BTUh. You may be familiar with BTU: British thermal units. The little h on the end of BTUh stands for hours. So you are looking to find out about the British thermal units used per hour.

The way that you measure how much air conditioning power you need to cool a room is done in BTUh. And the way that most BTUhs are measured is to give it 6,000 BTUh for the big room in your house and then whittle down to anywhere from 3500 to 5000 BTUh for each additional room. A large bedroom may require 5000 BTUh while your bathroom certainly won’t require much in the way of British thermal units at all. This is the standardized way of looking at how much energy is needed to cool your house.

But all houses are not built equally are they, Mr. Delay? While that 6,000 BTUh for the big family room may be mostly on target, you must take other things into consideration. For instance, a house that is very well insulated may not need that 6,000 BTUh in the family room. It may need only 5500 BTUh. But now let’s say your big family room is down in the basement where you have no windows or doors through which heat enters and the cool air escapes. Well, you might just be able to get down to 5,000 BTUh. The thing is that just as there are no absolutes in a world outside the Republican National Convention, there are no absolutes in the world of calculating your room cooling needs.

A number of elements contribute to high cooling bills. A house with a lot of shade trees won’t need quite the BTUh that a house unprotected by shade trees need. In order to get the most accurate reading of your BTUh you can hire an air conditioner contractor to do a run-through of your home. Of course, you may wind up having to pay money for that so here is a very, very basic rundown of how many BTUh you need for average square footage.

265 Square Feet: 6,000 BTUh

350-450 Square Feet: 9,000 BTUh

520-600 Square Feet: 11,000 BTUh

600-750 Square Feet: 12,500 BTUh

750-900 Square Feet: 15,000 BTUh

900-1050 Square Feet: 16,500 BTUh

1250-1600 Square Feet: 23,000 BTUh
