What Size Room Will A 5000 BTU Window Air Conditioner Cool?

A 5000 BTU air conditioner can cool a room of 100 to 150 square feet. Energy Star guidelines for 5000 BTU AC room sizing also recommend that you: Increase capacity for a room with a lot of sunlight, and increase cooling output by 10%.

This would reduce the size of the 5000 BTU AC room to 90-135 sq. ft. As with all AC units, the location is extremely important. If it’s an old unit, it’s probably not cooling to the potential that it was designed to. Consider having your present unit serviced and inspected to be sure the coils are clean and all gaskets are intact.

If this doesn’t help, you may need a new unit. A 5000 BTU AC will cool about 90-square feet under ideal conditions; more if there is good airflow, less if there is bad airflow (e.g., next to a radiator). If you live in an older or smaller home or have an open floor plan, you’ll get more bang for your buck with a smaller unit.

Consider a 3500 or even a 3000 BTU unit. If you live in a larger home with solid walls and good insulation, consider moving up to 6000-7000 BTU. We can help you choose the right air conditioner for your house. If you want to cool a larger room than the estimated 90 square feet that a 5000 BTU AC unit has the capacity to cool, you will need multiple units.

Multiple 5000 BTU AC units will much more efficiently cool a large room than two or three smaller units. 6000-7000 BTUs are capable of cooling up to 300 square feet, so if you want to cool more than 225 square feet, you’ll need two or three of these units (plus many smaller ones).

Where Should A Window Air Conditioner Be Placed?

The best height for a window-type AC is 3-4 feet from the floor. If you install the AC very close to the wall or in an airtight room, it will trip due to high head pressure because heat dissipation is impossible.

After installing the air conditioner, the distance must be greater than 900 mm, and the top of the shaft must not be closed. In addition, the distance between the AC and the wall should be equal to half of the unit’s length.

The first thing to do when purchasing a window air conditioner is to figure out what size you need. This may sound like common knowledge, but you would be surprised at how many people buy a window air conditioner without giving any thought to its size.

When purchasing an air conditioner for your room, it is very important that it has the proper cooling capacity rating. An air conditioner that is too powerful will not only cause damage to your room’s structure but will also end up costing you a lot of money.

An air conditioner with insufficient power will take longer to cool your room, and won’t cool it as effectively. The easiest way to figure out what size air conditioner you need is to look at the little rating tag on the back of your current air conditioner, or on the window seal where the old one was installed. It should say something like 5200 BTU (the number of British Thermal Units this AC unit can produce in an hour).
