How important is BTU in air conditioner?

How important is BTU in 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 BTUs do I need for an air conditioner?

The Rules for Keeping Cool Window air conditioners typically have a cooling capacity ranging from 5,000 to 12,500 British thermal units (Btu/hr.). As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space.

Is it better to have more BTU or less?

More is not better. 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. To be sure you’re making the right decision, call us to get answers about air conditioner sizes and efficiency.

Is a 12000 BTU AC good?

Air Conditioner Ratings 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. Manufacturers give their own ratings as to how much room area they believe their units can cool.

What BTU do you need?

How many btu do I need to heat 3,000 square feet?

Room/Area Size Heating Capacity(BTU) Examples
900 sq ft 40,000-49,000 BTU 30×30 garage
1,000 sq ft 45,000-55,000 BTU Small home, 2-3 bedroom apartment
1,200 sq ft 55,000-65,000 BTU 30×40 garage, 3 bedroom townhouse
1,300 sq ft 59,000-71,000 BTU Small/Average home, large apartment

Is a 5000 BTU air conditioner good?

A 5,000 Btu air conditioner can effectively cool a room that measures 100 to 150 square feet, according to a basic industry standard. Therefore, the best way to choose an air conditioner capacity is to start with the room’s square footage, and then make adjustments as needed for the specific space.

How many BTUs do I need to cool my house?

2. Find the correct cooling capacity for your room size

Area To Be Cooled (square feet) Capacity Needed (BTUs per hour)
100 up to 150 5,000
150 up to 250 6,000
250 up to 300 7,000
300 up to 350 8,000

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.

How much does it cost to run 12000 BTU AC?

How Much Does it Cost to Run a 12,000 BTU Air Conditioner? A 12,000 BTU air conditioner costs an average of $0.14 per hour to run. If the AC unit is used for 8 hours per day, then it costs $1.12 per day. Running the air conditioner for one month will cost around $33.60.

What should the BTU be on an air conditioner?

As the BTU rating on a particular unit increases, the size, weight and cost also goes up. 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.

What happens if there are not enough BTUs in an AC unit?

Using a portable air conditioner with not enough recommended BTUs will keep you from reaching your desired comfort level. The heat load will be too much for your unit to handle. This will cause your AC unit to run continuously and never reach your set temperature level. Not to mention shorten its lifespan.
