As you start shopping for a new air conditioner, chances are you’ll come across the acronym BTU. And that means what, exactly? 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 do I need for a 12×12 room?
If you want to properly cool down a 300 square foot area (or room), you need a 6,000 BTU air conditioner. Obviously, the problem arises when you have a tiny 12×12 room, for example. According to the US Department of Energy directive, an air conditioner’s most appropriate size would be 2,880 BTU unit.
Is more BTU better for air conditioner?
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 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.
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.
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.
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.
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.
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.
Is high BTU good?
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.
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.
How do you calculate BTU for a 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.
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.
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 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.
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.
What size room can a 10000 BTU air conditioner cool?
10,000 BTUs will cover 300 sq. ft. (2,400 cubic feet) 12,000 BTUs will cover 400 sq.
Do I need a 4 ton or 5 ton AC unit?
The answer to the question, “what size AC unit for 2400 square feet?”, would be, is 60,000 BTUs or 5 Tons. It’s possible to fall between unit sizes, so if that’s the case with you, then you should choose the next higher size.
