## How do I find the size in tons of a Midea heat pump or air conditioner from the serial number?

Monday, February 21, 2022

You can determine the size in tons of your Midea HVAC system by examining the model number (not serial number) on the data sticker at the side of the condenser (outdoor unit). Look for the two numbers in the middle of the series of letters. It should 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, using the Midea model number DLCRBH48AAK as an example, 48 divided by 12 equals 4, and the unit is 4 tons.

Here’s a rundown of the range you will encounter: 09 = 3/4 ton, 12 = 1, 18 = 1.5, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons.

Midea’s diagram below shows what each of the other letters in the model number mean.
