Quick Tip #35 – A Ton of Cooling

Updated: Apr 11, 2019

Ever hear of a two- or three-ton central air conditioner?

Does that mean a two-ton air conditioner weighs 4,000 pounds?

Is the term related to cooling capacity, or is it a random term that tech folks use to impress us?

When engineer Joe Cool (at least I think “cool” was part of his name ) developed the standards for measuring mechanical cooling, ice was commonly used for cooling.

You know, in the old days, when food was stored in the ice cooler, and there was no air conditioning. So Joe decided that the cooling capacity measurement should relate to ice.
