What size in tons is my Samsung heat pump?
Tuesday, May 19, 2020
You can determine the size in tons of your Samsung HVAC system by examining the model number on the data sticker at the side of the condenser (outdoor unit). ook at the first two numbers after several letters at the beginning of the model number. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU so, for the model number AR24SWSJWKNCV, 24 divided by 12 equals 2 tons.
Here’s a rundown of the range you will encounter: 09 = 3/4 ton, 12 = 1 ton, 18 = 1.5 tons, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons.
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. RLA is an acronym for Rated Load Amperage, and is what the maximum amperage should be when the condenser up and running. 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. 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. It averages around five times the RLA.
