When it comes to air conditioners, the BTU rating indicates how much energy is used to remove heat from the air. BTUs are an important element of cooling equipment tonnage, which is another measure of heat removal. The use of ton to measure heat removal is thought to have originated when buildings were cooled by ice.
How many BTUs of cooling do I need?
Size and Ceiling Height Area To Be Cooled (square feet) Capacity Needed (BTUs per hour) 100 to 150 5,000 150 to 250 6,000 250 to 300 7,000 300 to 350 8,000.
Is the higher the BTU better or worse?
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.
What does it mean 12000 BTU?
Twelve thousand (12,000) BTUs equals one ton. This term is more often used when talking about Air Conditioners, Refrigeration Systems, Heat Pumps, and Geothermal systems. A typical home would need somewhere around 36,000 BTUs, or 3 TONs, of cooling per hour on a very hot day.
Does higher BTU mean better cooling?
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.
What AC size 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.
What size room will 5000 BTU 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. Naturally, air conditioners with higher capacities have higher price tags.
Does BTU matter for AC?
If your air conditioner has a bigger BTU rating than the room size needs, it will cycle off too quickly, waste energy, and will not adequately dehumidify the space. So a higher BTU than needed is definitely not recommended.
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.
How big of a room will 12000 Btu cool?
12,000 BTUs will cover 400 sq. ft. (3,200 cubic feet) 13,000 BTUs will cover 450 sq.
What size room will a 14000 BTU air conditioner cool?
600-700 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.
What is the BTU for 1 ton AC?
The capacity of an air conditioner refers to the amount of heat it can remove. Rounding up 11,917 Btu/hr gives you 12,000 Btu/hr, which is one ton of air conditioner capacity.
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 SEER rating should I buy?
There’s no magic SEER number. Anything over 13 is great. Because if you have an old 8 SEER system and replace it with a 16 SEER unit, you could significantly reduce the cost of cooling your home. Don’t forget to look at tax credits and manufacturer’s rebates that can bring the down the cost of a high SEER system.
How do you calculate BTU for a room?
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.
What size air conditioner do I need for 1700 square feet?
ZONE 1 ZONE 3 2 Tons 901 – 1200 sf 1001 – 1300 sf 2.5 Tons 1201 – 1500 sf 1301 – 1600 sf 3 Tons 1501 – 1800 sf 1601 – 1900 sf 3.5 Tons 1801 – 2100 sf 1901 – 2200 sf.
Is it cheaper to leave the AC on all day?
In general, it is cheaper to leave the AC on all day during very hot temperatures. However, turning off the AC during a heat wave can quickly introduce a lot of heat and humidity into your home. After even just a couple of hours, your AC will have to work hard to lower the temperature back to a comfortable level.
How many BTU do I need for a 12×14 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.
Is it cheaper to run a window air conditioner or central air?
A window unit comes in at a way cheaper price of around $300-$1,500 with monthly running costs of about $30-$80 depending on its usage. However, if you’re planning to cool more than 5 rooms, then one central air conditioner will be cheaper in the long run.
