Tonnage
It’s important that you have the right size unit for your home. HVAC manufacturers make it easy to determine the nominal capacity of your ac unit. In order to determine what size unit you currently have, look at the data plate on the outdoor condensing unit and locate the model number, not the serial number. You’re looking for 3 digits in the model number that match the numbers below to indicate the tonnage or btu of the unit. For example, you’ll see the number 048, this indicates that you have a 4 ton or 48,000 btu air conditioner.

If you are replacing your air conditioning system, look at what size you have. If the unit you have now is the correct size for your home, replace it with the same size. How do you know what size you currently have? Look at the data plate on the outdoor condensing unit and locate the model number (not the serial number). You are looking for 3 digits in the model number that match the numbers below to indicate the tonnage or btu of the unit.
012 = 1.0 ton = (12,000 btu)
018 = 1.5 ton = (18,000 btu)
024 = 2.0 ton = (24,000 btu)
030 = 2.5 ton = (30,000 btu)
036 = 3.0 ton = (36,000 btu)
042 = 3.5 ton = (42,000 btu)
048 = 4.0 ton = (48,000 btu)
060 = 5.0 ton = (60,000 btu)
NOTE: If you have multiple AC unit on your home, you can use the same square footage estimator based on how much area each unit covers. Your install contractor will verify during the job site inspection that you have ordered the correct tonnage, and assist with any necessary correction to your order prior to installation.
