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. It may seem overly technical, but BTU is an important metric that can help you determine the kind of air conditioner you need for a home your size.
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 much AC BTU 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.
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 big of a room will 12000 BTU air conditioner 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.
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.
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.
Does higher BTU use 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.
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 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 choose an air conditioner for my room?
First, find out your the area of you room. Then divide it by 600 to get the basic capacity. So, if you room is 100 sq. feet, the basic AC capacity required will be 0.167 tons (100 / 600).
What size room will a 18000 BTU air conditioner cool?
800-900 sq ft Cooling Capacity (BTU): Room/Area Size: 14,000 BTU air conditioner room size: 600-700 sq ft 16,000 BTU air conditioner room size: 700-800 sq ft 18,000 BTU air conditioner room size: 800-900 sq ft 20,000 BTU air conditioner room size: 900-1,000 sq ft.
How many sq ft will 18000 BTU cool?
BTU Sizing Chart for Mini Split Systems Area To Be Cooled Capacity Needed (BTUs Per Hour) 450 to 550 square feet 12,000 BTUs 550 to 700 square feet 14,000 BTUs 700 to 1,000 square feet 18,000 BTUs 1,000 to 1,200 square feet 21,000 BTUs.
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.
Is it better to oversize or undersize AC?
While undersized AC will be running nearly all the time, an oversized AC will be stopping nearly all the time. The frequent starting and stopping aren’t good for your AC; it accelerates the wear and tear of its different components. The AC needs to run for a reasonable time to extract the extra humidity from the air.
Will a bigger AC unit cool my house faster?
A bigger air conditioner will cool the home faster. The thermostat, being on the main floor away from the walls and windows will typically be blasted with that easy cold air and will be satisfied in a matter of a few minutes.
Is 12000 BTU too much?
The most common window air conditioning units come in cooling capacities ranging from 5,000 to 12,000 Btu. A 12,000 Btu air conditioner can cool between 450 and 550 square feet of floor space. A 12,000 Btu unit could cool a room 25 feet long by 20 feet wide that has 500 square feet of floor area.
