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 higher BTU better for AC?
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 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.
How many BTU do I need for a 12×12 room?

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.
Can Window AC cool entire house?
Window air conditioners are designed to cool only a single room. It is very difficult for such AC to cool an entire house. At most you can cool two adjacently connected tiny rooms with a single window AC, but there will be uneven cooling.
Is 9000 BTU enough for a bedroom?
Match the BTU rating to the room size Small rooms (150 square feet or below) will require a unit with around 6,000 BTUs. This is generally appropriate for a single bedroom. For larger rooms (up to 350 square feet), you will need a unit with around 9,000 BTUs. This is typical for most living rooms.
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.
Is 1 ton AC enough for what room size?
Room size and power consumption Here tonnage plays an important role. For instance, a 1-ton window AC or a 1.5 ton split AC is an ideal choice for rooms measuring up to 150-160 sq ft. Star rating of AC essentially refers to how efficient the air conditioner is in converting electricity to cool air.
Do they make 7000 BTU air conditioner?
SereneLife12,000 BTU (7,000 BTU, DOE) Portable 4-in-1 Air Conditioner with Heater in White for Rooms Up to 450 sq. ft.
How big AC do I need?
To calculate for yourself how big of a central air conditioning unit you need, multiply your home’s total square footage by 20. Divide that total by 12,000. Then subtract 1.0 for the total number of tons you need.
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.
Does higher BTU mean more electricity?
The more BTU your unit produces, the more energy it consumes. So, if you are worried about high energy costs, you should get a unit that is appropriate for your space.
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.
Does more BTU mean colder?
A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space.
Which is the best time to buy AC?
Off-season (spring or autumn) is the best time to buy. Autumn is the best time for maintenance. Start shopping around well in advance before you need a new air conditioner, not just when the warmer months come around. This will ensure cheaper prices and shorter wait times for installation.

Which type of AC is best for home?
If you’re looking for whole-house cooling, and you already have ductwork in place, this is the most popular option. Central air conditioning is the most efficient way to keep your whole house cool. You can expect lower energy bills alongside better indoor comfort, cooler temperatures and lower humidity.
