How much is a pound of R22 freon?
R22 Freon costs $90 to $150 per pound installed or $13 to $21 per pound wholesale. R22 refrigerant is the old standard for residential air conditioners, which is now banned and no longer produced. Older AC units can still be refilled, but R22 prices are rising as the supply decreases.
Is it legal to add Freon to a leaking air conditioner?
Section 301 states: No person shall add refrigerant to any motor vehicle air conditioning system unless that system has no detectable leaks. It further requires a visual inspection followed by the use of an electronic leak detector (which meets SAE Standards). Other California AQMDs have passed similar regulations.
