Air conditioner size FAQsTo calculate the size of air conditioning you need, calculate the square footage of your home and multiply it by 20 to get the necessary BTUs. A 12,000-BTU unit will cool a space of 400 to 600 square feet. A two-ton air conditioner will cool a space of 1,500 square feet. To calculate the size of the unit you'll need, you'll need to know the square footage of the room or house.

To find square footage, multiply the length by the width of the rooms in your house and then add them together. Once you have the square footage, multiply it by 25 to get the BTUH needed to cool your space. There are 12,000 BTUH in a ton. One of the main deciding factors will be the square footage of the space you need for cooling. However, this isn't as simple as it sounds. Whether you're moving to a new home, upgrading an existing one, or building a home from scratch, one of the most important decisions you need to make is which air conditioning system to install.

In addition to everything mentioned above, there is a formula that can be used to determine the required tonnage of a **central air conditioning** system. The main factor in choosing the right size air conditioning system is the square footage of your home. A window air conditioner can have between 5000 and 10,000 BTUs, while residential central air conditioners average between 20,000 and 50,000 BTU.
