Getting the right size air conditioner is important for reducing your costs of installation, operation, and maintenance. Learn what AC size means and how a professional determines the exact size you need for your home.
How AC Systems Are Sized
Air conditioner size refers to the cooling capacity it offers, which is measured in British Thermal Units, or BTU for short. You may also see it expressed in tons or tonnes, which is equivalent to 12,000 BTU per ton. A single BTU is the amount of heat needed to raise one pound of water by one degree Fahrenheit. The BTU rating on an air conditioner tells you how much heat the unit can transfer out of your home for each hour of operation.
Your Home’s Size
The first step to determining your cooling capacity needs is your home’s serviceable area. This could be as simple as looking at the last real estate listing. However, you need to check your attic, garage, and basement to see if the system services those areas too.
Consider Your Home’s Construction
How your home is built will affect the amount of cooling capacity you need. This includes the amount of insulation you have, how well your home is sealed, as well as the number of exterior doors and the number of windows, and the direction they face.
Look At Other Variable
Beyond your home’s construction, there are other factors that you need to account for in sizing your AC. These include:
- How much shade your home receives
- The number of occupants you have and when
- Heat generating appliances in your home
