1 As an example 5 years ago R22 sold for $10 per pound. 2  Today R22 can be as much as $50 per pound. 3  Typical residential air conditioning unit hold from 5 to 15 pounds of R22. 4  If a coil has to be replaced or there is a leak the cost of refilling the refrigerant could be $250 to $750.
Put a vacuum pump on the system and put 2.5 kilo of r22 back into system, I charged the customer $100 in total for the gas and my time. Because of mandated production cuts in R-22 (the most common household refrigerant) the cost of freon has doubled over the last couple of years.ou should never have to top up your air conditioner unless there is a leak in the system, simple as that. If some one tells you other wise they do not know what they are talk â¦ ing about. Take for instance, I have a fridge at home it would be 40 years old and has never been looked at.
