Help sirs bakit ganon kapag naka off ang aircon ok naman ang hatak pero kapag naka on parang ang laki ng power loss na hirap humatak.

two things:

a. have your compressor electrical load checked.
b. have the compressor pulley checked, baka matigas na.

yung na experienced ko dati, struggling when AC is on, kasi di nabalik yung vacuum hose na maliit from alternator to idle up nung ginalaw ito, pero not sure if sa bagong sasakyan which dependent on sensor, baka iba mechanism nung idle up.

kung low idling kapag nag engage compressor, isa sa posibleng dahilan ay sira idle up sensor.

ano engine mo bro?

Gasoline po sirs

Wala naman kaya siya connection sa engine mismo? Kaya hirap humatak?

Kung dati ok naman ang hatak kahit naka On ang AC possble hindi sa engine yan.
Eto mga possible cause base sa experience ko sa mga naging sasakyan ko.

1. Possible AC compressor bearing maganit na umikot, or yung compressor mismo. Kaya heavy load sa engine on Ac on. Take note iba pa ang compressor clutch bearing ha.
2. Possible nag high pressure and A/c system. cause nito is clog system line (condenser, evaporator, hose line, etc) usually kapag naghigh pressure na ang system, hirap na and compressor kaya nahihirapan din ang engine.

maganda pa check mo muna ang AC system mo, makikita ng isang reputable AC shop yan pag kinabitan nila gauge ang Ac system ng kotse mo.

so yung compressor pala ang culprit ng rough idling ng makina while the aircon is on? yan kasi ang dilemma ko ngayon after repairing the aircon system ng tsikot ko (it's a 15 year old car, BTW). hindi ba kailangang ipaayos yung idling system ng makina even if the aircon is on?
