For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner? Make sure you use RLA and not LRA, Locked Rotor Amperage, which is the surge of amps necessary to overcome inertia and start the system. If you divide the RLA by 6 for older units and 5 or 6 for newer units, you should get a number that approximates (not exactly) the tonnage of the system. RLA is an acronym for Rated Load Amperage, and is what the maximum amperage should be when the condenser up and running. If you are unsure whether you have found the right two numbers, you can double-check it by looking for the “RLA” rating on the data plate.

Here’s a rundown of the range you will encounter: 18 = 1.5 tons, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons, and 60 = 5 tons. A ton of air conditioning equals 12,000 BTU, and 36 divided by 12 equals 3, so the data plate below indicates the system is 3 tons. Look for two numbers towards the end of the model number that are divisible by 6 or 12, and represent the nominal BTU of the system in thousands.

You can determine the size in tons of your Payne HVAC system by examining the model number on the data sticker at the side of the condenser (outdoor unit).
