A beheld analysis should be performed to analysis for dye and/or oil (some manufacturers put UV dye in A/C systems from the factory).

Check all AC apparatus including the AC compressor advanced allowance & evaporator cesspool tube. If the refrigerant aperture is not evident, verify that dye is in the arrangement or add dye (one adjustment is with a dye injector).

You may again use an ultraviolet ablaze (UV Light) additionally alleged a atramentous light, to audit all AC components.

Check the absolute arrangement with an cyberbanking aperture detector, the evaporator can be arrested at the evaporator cesspool tube.

After the adjustment has been made, angle up an AC exhaustion pump, and let the arrangement break in a vacuum

for at atomic fifteen minutes. About-face the exhaustion pump off and watch the AC barometer to see if the exhaustion holds. If a accident of exhaustion is noted, this could announce a ample leak, possibly from an o-ring on a basic that was aloof formed on. Tip back abacus refrigerant oil; After abacus oil to the arrangement abreast or in the compressor, about-face the compressor by duke ten revolutions to anticipate accident to the compressor (oil cannot be compressed). Warnings; 1. Do not allegation refrigerant into the aerial ancillary 2. Do not over-charge the system, accident to the compressor can occur. 3. Always abrasion assurance glasses back alive on air conditioning systems, alike with the freon removed oil can aerosol from an accessible AC band acquired by trapped freon aback casual through a restriction.

You will charge an AC Barometer Set, an Cyberbanking Refrigerant Aperture Detector, an AC exhaustion pump, a UV Ablaze and a thermometer.
