    How to bleed the air off a Condenser?

    Had a customer call me after their A/C units stopped working. They had a maintenance mechanic from a neighboring restaurant take over the PM on their units (cost effective). He told them their cooling problem was air in the lines of their units and that he had to bleed off the air from the units then top them off with freon. The owner got charged for 10# of 134A to replace the air in their 4 systems. Too bad they were R22 units.....

    This is where that air depressor comes in handy.

    I would write a very specific set of findings, and a detailed critique of the previous work and charges.

    I wouldn't even attempt to bleed air off of a small unit.

    I'd pull the charge, evacuate and liquid charge what was in the cylinder. Once the cylinder was down to the last few ounces of liquid, I'd crack open the new stuff and top up the charge if needed.

    Either that or bleed air off of the recovery cylinder until it matches up with PT chart.
