How do I determine the size in tons of a Daizuki heat pump or air conditioner?
Monday, July 11, 2022
You can determine the size in tons of your Daizuki HVAC system by examining the model number near the top of the data sticker at the side of the condenser (outdoor unit). Look for the first two numbers after several letters of the model number They are divisible by 6 or 12, and represent the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 18 divided by 12 equals 1.5, so the data plate below indicates the system is 1-1/2 tons.
Here’s a rundown of the range you will encounter: 9 = 3/4 ton, 12 = 1 ton, 18 = 1.5 tons, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, and 48 = 4 tons.
To determine the date of manufacture of a Daiuki system, see our blog post How can tell the age of a Daizuki air conditioner from the serial number? To find out the age of another brand of air conditioner or heat pump, go to How do I determine the age of my air conditioner?
