Multi-read content how to calculate btu needed for air conditioner

What size air conditioner do I need?

There are several indicators you should consider before buying an air conditioner. You have different EER and SEER ratings, power, amperage, voltage, etc.

theMost importantthe measure ismating ability(measured in BTU/hour). This representsthe size of your air conditioner.

Meaning of BTU: British Thermal Unit or BTU/h is a unit that defines the cooling/heating capacity of an HVAC unit (air conditioner, heater, etc.).

What is BTU as an AC unit? In simple words, it is the capacitance or capacity of alternating current.

The higher the BTU, the more efficient the air conditioner can be.

Here is an example of how you can calculate how many BTUs you need to cool a 500 square meter area with 8 meter ceilings, average sun exposure, average climate, and excluding the kitchen .(you can find this BTU calculator below and use it for your case; with room size chart from 4,000 to 24,000 BTU):

how many btu air conditioner you need calculator

In short, you will need a10,000 BTU air conditioner.

How many BTUs do you need to wisely cool a certain amount of square space?

There are only 2 rules:

  • Not so big.
  • Obviously you don’t want a
  • 14,000 BTU Window Air Conditioner for Small Room 12×12
  • because it unnecessarily increases your energy bills.
  • Not too small.
  • You don’t want to be hot in the summer because you bought one
  • 6,000 BTU portable air conditioner for a 1,000 square meter apartment
  • .

The BTU required to cool a room containing known sequences can be calculated. According to the U.S. Department of Energy recommendations for room air conditioner sizing:

“…An air conditioner typically requires 20 BTUs per square foot of living space.”

Based on room size, ceiling height, and other conditions, you can calculate how many BTUs your air conditioner needs:

Air Conditioner BTUs

As you can see, the neat square foot to BTU converter gives you an idea of ​​what air conditioner dimensions you should consider in a “square foot to BTU” way.

measuring rooms for air conditioner btu sizeMeasure the square footage beforehand to get the right size for your air conditioner.

If you want to properly cool a 300 square foot area (or room), you need a 6,000 BTU air conditioner. Obviously, the problem arises when you have aBedroom 12×12, For example. According to the US Department of Energy guideline, the most appropriate size for an air conditioner would be 2,880 BTU units. The best you can do here isbuy a small 5,000 BTU window or a small 8,000 BTU portable AC unit (more on smaller AC units here).

For example, trendy portable air conditioners have cooling capacities of 6,000 BTUs to 14,000 BTUs. Based onReduce size, the average size of studio apartments in the United States is around 500 square meters. This means that for a small apartment you do not need expensive central air conditioners. You can install a mid-sized 10,000 BTU portable air conditioner, which will save you a lot of money.

Pro Tip: Always Buy OneThe AC unit is a bit largerthan this recommendation. Example: When using the BTU calculator below and you get, say, 10,000 BTUs for a 500 square foot area, start looking for a 12,000 BTU air conditioner. Your electricity bill will be slightly higher, but you won’t have to sweat if you buy an undersized AC.

To better illustrate the size of air conditioner you need, see the BTU chart:

Air Conditioning BTU Chart; Sample room size 12,000 BTU (1 ton)

Question:whatAir-conditioned room area 12,000 BTU? 12,000 BTU equals 1 ton; we are talking about a 1 ton AC room size.

To respond:Using the EPA’s rule of thumb of 20 BTUs per square meter, the room size of a 12,000 BTU air conditioner is 600 square meters. Similarly, the size of a 1 ton AC room is about 600 square meters.

Here is an approximate room estimate chart for different cooling capacity air conditioners to help you:

4,000 BTU Air Conditioned Room Size: 100-200 square feet Chamber 10×10, chamber 12×12, chamber 14×14
6,000 BTU Air Conditioned Room Size: 200-300 square feet 16×16 room, small apartment
8,000 BTU Air Conditioned Room Size: 300-400 square feet Chamber 18×18, chamber 20×20
10,000 BTU Air Conditioned Room Size: 400-500 square feet 22×22 bedroom, small studio
12,000 BTU air-conditioned chamber size: 500-600 square feet 24×24 room, medium studio
14,000 BTU Air Conditioned Room Size: 600-700 square feet 2 rooms, small apartment
16,000 BTU air-conditioned chamber size: 700-800 square feet 2 rooms, average apartment
18,000 BTU Air Conditioned Room Size: 800-900 square feet 3 rooms, above average apartment
20,000 BTU Air Conditioned Room Size: 900-1,000 square feet 3 rooms, larger apartment
24,000 BTU Air Conditioned Room Size: 1,000 to 1,200 square feet 4 rooms, large apartment

Again, when narrowing down your air conditioner choices, knowing how much you need to cool a large area is your best friend. Based on this, you can calculate square footage in BTUs and instantly know what BTU range your perfect AC unit should be.

For example, if you buy a 14,000 BTU portable air conditioner to cool a 12×12 room, you’ll end up with a cold room and over $100/year in unnecessary electric bills.

The perfect BTU air conditioner for the size of the room

According to the recommendation of the United States Department of Energy, the number of football fields is20 BTUs per square foot. This is already a very good estimate.

The simplest formula for calculating BTUs for an air conditioner has the following form:

BTU = square feet × 20

However, to get a perfectly sized air conditioner with just enough cooling capacity and not expending too much energy, you need to consider a few additional factors. That is to say:

  1. Room height.
  2. local climate.
  3. Lounge.
  4. Number and size of windows.

BTU calculators and charts work best for standard room heights. Obviously, if you have high ceilings (older buildings have 10 foot ceilings), you need to add a bit more cooling capacity in the BTU.

There is also a difference if you live in Texas or New York. The local climate in Texas is, on average, warmer, so you should need an air conditioner that adds some 1,000 BTUs.

The same goes for sun exposure. If the room or area you want to cool is often exposed to the sun, you will need a larger air conditioner.

In addition, the walls also block the sun very effectively. Windows does not. If you have large windows and there are many of them, the sun will heat your house more.

To sum up, when do you need an air conditioner with a higher BTU than the standard recommendation:

  1. If you have
  2. high wall
  3. .
  4. If you live in a
  5. warm climate
  6. . For example: California, Texas, Florida, New Mexico, etc.
  7. If the specific room you want to refresh is
  8. face the sun
  9. more often than not.
  10. If you have a
  11. above-average size and number of windows
  12. .

For example:If you have a 500 square meter solar cabin near Texas with lots of picture windows, you should check it out.10,000 BTU air conditioner(as recommended). For example, you would be better off considering a 14,000 BTU portable air conditioner.

What Does BTU Mean in Air Conditioners (Summary)

The BTU in an air conditioner is simply a measure of how efficiently a particular AC unit can produce.

We wanted an air conditioner with moderate cooling efficiency. That’s why, knowing the square footage of the area we want to cool, we can calculate how many BTUs our air conditioner should have.

Equation for ‘square foot to BTU’Pretty simple – multiply the square feet by 20. That means a 500 square foot room needs a 10,000 BTU air conditioner. Of course, be sure to purchase a slightly more powerful air conditioner if you have high ceilings, live in a hot climate, and get above-average sunlight in those rooms.

For small spaces (ex:camping air conditioner for tent), you can usebattery-powered portable AC unit.

You should use the BTU calculator when choosing different types of air conditioners, including:

  • AC separator.
  • . For example:
  • Mr. Cool’s sub-unit
  • has the highest SEER rating above 20 EER.
  • portable air conditioner
  • . Here you can check
  • largest (up to 15,000 BTUs)
  • ,
  • the quietest (less than 50 dB)
  • , and
  • portable AC with heater
  • . These are
  • best portable ac unit for apartment
  • , For example.
  • AC window unit.
  • . Here you can check
  • largest (24,000 BTUs)
  • ,
  • quietest (less than 42 dB)
  • , and
  • Window air conditioner with heater
  • . Special types of window AC units include
  • AC unit housing window.
  • ,
  • AC unit through the wall
  • ,
  • Window Saddle AC Unit
  • , and
  • low profile window unit
  • .

To note: Evaporative coolerandmini personal air freshenerdoes not produce a cooling effect which can be expressed in BTUs. They use evaporative water instead of refrigerant-based systems to provide efficient cooling.

Description:

How to Calculate the BTUs for Your Room When it comes to room air conditioners, it’s important to have the proper sized unit. If you have an air conditioner that’s too large for the room, it’s going to shut off early and not have enough time to dehumidify and remove the moisture necessary. This will leave you with a very cold and clammy environment. On the other hand, if the air conditioner is too small for the environment that you’re cooling, then the air conditioner will continually run and never cool or dehumidify the room properly, therefore costing you more in energy.

So how do you find the right BTU size air conditioner for your room? It’s quite simple; you simply measure the square footage of the room. This is the length multiplied by the width of the room. If it’s on the main floor, multiply the square footage by 30. If it’s a second floor or kitchen area, multiply the square footage of the room by 40. If your ceiling height is over 8 feet, add 1,000 BTUs for every foot over that 8 foot ceiling height. Also take into consideration the number of people in the room. For each person over the first two individuals, add an additional 600 BTUs to your formula.

Example: You’re looking for an air conditioner for a 10×15 room on the second floor with a 9 foot ceiling. A 10×15 room equals 150 square feet. Since it’s on the second floor, multiply 150 by 40 to give us 6,000 BTUs. We mentioned that the ceiling height was 9 feet, so we want to add an additional 1,000 BTUs. You will need a 7,000 BTU air conditioner to properly cool this space.

A friendly and knowledgeable P.C. Richard \u0026 Son sales associate would be more than happy to help you calculate the amount of BTUs you’ll need for your space and find an air conditioner that will suit your needs. Click, call, or stop by today!
