Air Conditioner Sizes: How to Calculate Air Conditioner Size?

How to calculate air conditioner size correctly for a home? First, you must know the BTU (British Thermal Units) evaluation of this air conditioner you are considering, then you want to find out the corresponding amount of BTU’s necessary for your house. Eventually, they multiply the two together, getting the sum of cooling power your air conditioner needs to cool down your house efficiently. You may find this bit overwhelming and confusing at first, but it really isn’t that complicated.


How to Calculate Air Conditioner Size?

Air conditioners come in all shapes and sizes. Some are energy efficient, so that they can help save you money on utility bills. There are three types of air conditioners: window type, central-heater kind, and radiant floor-mounted type. Window kinds have cooling needs dependent on the size and style of the area where they’re installed. Central-heater air conditioners are used in larger rooms, while glowing floor-mounted air conditioners are designed to cool large distances such as entire buildings or office buildings.


To calculate air conditioner size, first you need to determine the BTU requirements for your home. If you live in a small house, obviously, you’ll require a smaller air purifier compared to those homeowners that reside in huge houses. You also have to consider the number of rooms within your home. In case you have two or more rooms, then multiply their joint BTU requirements. Now you’re ready to calculate the cooling abilities of the different air conditioners.

The simplest way to calculate air conditioner size is to divide the whole length times the width times the height. As an example, if your home has a height of six feet, then you need to split the entire length by six occasions and come up with a practical number. As soon as you have this sensible number, simply multiply it with the width. This way, you receive the cooling power of the unit. Note that you need to add two to your ground and one for the wall when you are doing this calculation.

You might also compute cooling powers based on the side windows of the room. In case you have one big window, then the characters which come out should be quite different from people with two small side windows. The reason why the calculations differ is because the heat produced by the A/C unit differs. If you don’t want to do it by hand, then you should use this machine which is included with a program that will compute all of the relevant details that you want.




If you’d like another air conditioner size calculator, then you should go on the internet and check out the HVAC sizing calculator. This calculator can be very valuable to all homeowners that are planning to purchase or lease a A/C unit. All you have to do is plug into the necessary details into the machine, and also the dimensions and HVAC specifications will be displayed instantly. There are different options available once you are using this hvac sizing calculator, like the amount of BTUs that the machine has to be able to run. This is a great feature to consider since it permits you to fit the cooling capacity of the machine into the size of this room where it is going to be installed.

If you aren’t certain about the AC dimensions which you should select, then you need to speak to a local HVAC technician and request advice. The technician can help you in picking the ideal A/C for your dwelling. However, if you understand how big your air conditioning needs to be, then it is simple to calculate it using some of the above calculators. You simply need to be certain you provide accurate advice to the calculator. If you’re using a older A/C which has a thermostat which regulates the temperature, then you need to use the exact same type of calculator which you would use to figure its cooling capability.

Once you’ve decided on the ideal air conditioners for your home, you should install them using the appropriate screws and adhesive. It is necessary to read the directions provided with the device carefully before you begin to install it. You should also make sure you shut down all unnecessary appliances until you put in the air conditioners. In this manner, you will be able to figure the cooling capability of the machine as well as the heating capacity until you put in it.
