How can I tell the size in tons of a Pioneer mini-split heat pump from the model number?
Saturday, September 25, 2021
Look for two numbers in the center of the model number that are divisible by 12 or 6, which is the BTU rating times 1,000. A ton of air conditioning equals 12,000 BTU, so a 12 would indicate 1 ton. Here’s couple of examples: WYS024GMFI19RL = 2 tons, and WYS018GMFI19RL = 1.5 tons. And then there’s the odd one that doesn’t exactly fit the system: WYS009GMFI19RL = 3/4 ton.
