As you start shopping for a new air conditioner, chances are you’ll come across the acronym BTU. BTU is short for British Thermal Unit, a unit of measurement that shows just how much energy your air conditioner uses to remove heat from your home within an hour.
How many BTU air conditioner do I need?
As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space. But other considerations, such as the ceiling height and the size of your windows and doorways, might call for more cooling power. To measure your room, multiply the length by the width.
Is a higher BTU air conditioner better?
A measure of an air conditioner’s power is its BTU rating. BTUs are the energy used to remove heat from a room. Therefore, the more BTUs an air conditioner unit has, the better equipped it is to cool a larger space.
How many BTU do I need for a 12×12 room?
6,000 BTU Room Type Room Size Recommended BTU 12 x 12 room 144 sq ft 6,000 BTU 12 x 24 room 576 sq ft 14,000 BTU 13 x 13 room 169 sq ft 6,000 BTU 14 x 16 room 224 sq ft 7,000 BTU.
How many square feet will a 12000 BTU air conditioning cool?
The size of your space determines how much cooling capacity you need. Budget air conditioners range from 5,000 BTU, which can handle about 150 square feet, to 12,000 BTU, enough to cover about 550 square feet.
Is 8000 BTU enough for a bedroom?
Recommended BTU By Room Size If you are looking for an air conditioner for a room measuring say 10′ x 15′ (150 square feet), the recommended BTU range is up to 5400. Once you get into 340 and 400 square feet per room, you’d need an 8,000 or 9,000 BTU air conditioner, respectively.
What happens if you have too much BTU?
A unit with too many BTU’s, will cool the room fast, but leave the room humid. Too few BTU’s will never cool the room down and the unit will run incessantly.
What happens if BTU is too high?
If the BTU is too high, your room will cool too quickly and that can cause the air conditioner to cycle more often. That places a considerable amount of load on the compressor and can shorten the lifespan of the air conditioning unit.
Does higher BTU mean colder air?
Higher BTU ratings mean a more powerful air conditioning system, but you also don’t want to overspend if you don’t need to. How many BTUs you need to cool your room depends primarily on the size of the space; that is, how much air you have to cool.
How do I calculate air conditioner size?
Calculate Size To calculate the size, simply multiply the length times the width of the room or area to be cooled. Then, as a practical number, multiply that total times 25 BTU. This allows ample cooling, whether it is a rainy, moist day or a hot, sunny, humid day.
How do I calculate BTU for my house?
For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x . 133 = BTUs needed per hour.
How do I calculate what size air conditioner I need?
To calculate the size of the air conditioner you need for a room, first, multiply the length of the room with its width. Then multiply it with 25 BTU to get the ample cooling for the room under different weather conditions. For example, if the room is 15 feet long and 12 feet wide, it comes to 180 square feet.
How many rooms will a 8000 BTU air conditioner cool?
Air Conditioner BTU Chart; With 12,000 BTU (1 Ton) Room Size Example Cooling Capacity (BTU): Room/Area Size: 8,000 BTU air conditioner room size: 300-400 sq ft 10,000 BTU air conditioner room size: 400-500 sq ft 12,000 BTU air conditioner room size: 500-600 sq ft 14,000 BTU air conditioner room size: 600-700 sq ft.
Do air conditioners take a lot of electricity?
In the typical home, air conditioning uses more electricity than anything else—16% of total electricity used. In warmer regions AC can be 60-70% of your summer electric bill, according to Austin Energy.
What size air conditioner do I need for a 2400 square foot home?

How many BTUs do I need to cool my house?
Size and Ceiling Height Area To Be Cooled (square feet) Capacity Needed (BTUs per hour) 450 to 550 12,000 550 to 700 14,000 700 to 1,000 18,000 1,000 to 1,200 21,000.
How many BTUs is 1hp aircon?
When choosing an air conditioner, usually a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity. The higher the listed BTU/hr, the greater the cooling capacity.
