No complicated math required, you simply add together the gas in the pipe, the compressor/condenser section, and the evaporator = total charge. As a result, they only capture between 30-40% of the system charge and therefore under report capacity charge.
How much refrigerant is in an AC unit?
Most AC units hold 4 to 6 lbs of Freon, and depending on the type of refrigerant, a pound of Freon may cost between $65 - $85 and up to $150 per pound for R-22 which is being phased out as part of the Clean Air Act. So adding a few pounds of Freon without finding out why it is leaking can be a costly mistake.Jun 1, 2017
