    dalawa kasi leak eh, isa sa piping tsaka ung evaporator. aftr around 6 months from 1st use di na lumalamig kaya di ko na ginamit. pwde ko ba ipatest ung compressor? tapos kun ok pa ipavacuum ko. ano ba gagawin pag bina-vacuum ang a/c para alam ko din na bina-vacuum nga nila a/c ko. tsaka ung calibration ba pressure ng low at high side lng iche-check?
    ung fan ok naman, pulling ung direction ng hangin from condenser. ni-relay ko na eh direct sa batt.

    Kabitan mo ng gauge manifold tapos paandarin mo aircon. Ask somebody to keep the rpm steady at 2000 rpm. Tignan mo yung low side kung bababa and steady. Kung bumaba at steady (20-30 psi), ok ang compressor mo. Kung ang reading naman is around 30 to 40 psi and steady at that, try adjusting the expansion valve. Tignan mo din yung hi side kung tumataas. Ang normal reading is around 200psi. Higher than that hi pressure na. If that is the case check your condenser and condenser fan.

    Yung vacuum, may ikabit dapat sila na vacuum pump that will suck the air out of your system.

    mga sir, na check na namin ng pinsan ko, high pressure talaga ung low side, 60psi eh. diba ang taas na nun. una binuhusan namn ng tubig ung condenser kasi pag nabasa raw un at may makikitang bula sa drier di daw ung overcharged. pero 60psi pa rin kaya binawasn namin ng freon hanggan medyo may maliit na bula na ung drier. 60psi pa rin reading. totoo kayang nag flush ung shop na nagrepair nito? ano mga possible causes ng high pressure sa low side? tulong na man po.

A/C di masyadong lumalamig
