airco compressor turns on and off everey 2-3 secs.

[maimaicomp]

go to another shop who can.

by the way...............


what were the pressures at around 2000 rpm with both front and rear units on?

is your system manual or automatic (climate control)?

ok pag front a/c lang pero short-cycling pag umaandar ang rear a/c? undercharge yan pag ganyan.

thanks po sa reply mga sir, napagawa ko na yung sasakyan dito lang sa tabi tabing shop, overcharged pala ng freon ang dahilan, ginawa nila pinasingaw nila lahat ng freon tapos na refill ulit ng bago, ang sabi kailangan bagong freon ikarga dahil nung pinasingaw nila yung freon ang daming hangin at hindi daw purong freon. baka nakatayo daw yung tangke nung kinargahan ng hyundai north edsa yung sasakyan kaya masmadaming hangin kesa freon. ok na yung starex ko ngayon parang bago ulit sobrang lamig.

*jick.cejeco umabot ng 450 yung pressure nung binuksan yung rear aircon. naka idle lang yung engine. sabi delikado daw yun at maaaring masira ang compressor. pinapatay nya agad yung aircon sakin nung tumataas pa yung pressure sa 450.

*yebo opo ok sya pag front AC lang, pero pag binuksan lang yung rear tsaka nag off and on yung compressor ng 1-2secs.

Dammnnn If I were you rereklamo ko yan sa SA ng casa. Imagine sa halip na mafixed ang aircon mo they could potentially induce another fault due to that overcharging of your AC system. Think of gross incompetence, ayaaayyy. Masakit pa nun bumayad ka para halos sirain ang AC mo :lasing

For knowledge purposes the gases inside the system other than R134a are called (NCG) non condensable gases. If you use the pressure/temperature chart, match the pressure against the temperature closest to or that of the containment. If the pressure is higher than that of the P/T chart at a given temperature the refrigerant is not pure or is lower than 98% purity

*jick. Sir you seems to be very knowledgeable on HVAC. Can you pls confirm that with the current car ACU refrigerant, you can't just do a top up or refilling of refrigerant? Techs says magkaron daw imbalance ng freon content kaya need to depressurize and evacuate the whole system pa . Appreciate if you could share theory on it😊

Use the P/T chart and measure the ambient temperature within ten feet of the car. Then, with the system running and stabilized, check the low side pressure and the outlet center register temperature

So wala pala scientific basis yun? Dammn rip off na naman ng mga aircon shop! What a Waste of resources 😔

Curious lang ulet how to measure yun outlet center temp.? Say sa car vent how far and what measuring instrument kelangan? And you need to measure din pala ambient temp by what type of instrmnt ulet?

[jick.cejoco]

You can use cooking thermometer, I/R non contact thermometer, DMM with a thermocouple probe as long as the range includes 30-120 degrees fahrenheit

maari bang ma recalibrate (or marepair) yung lumang compressor ng kotse para lumamig ulit yung aircon?

kung meron, mga magkano ang aabutin?

i read an artricle on that, some time back.
the (branded) name claims they can do it. but they added that the repair might not last as long as the original. maybe as short as a year only... but it's a lot cheaper than a brand new compressor.
sorry. i can't remember the name...

my two bits' worth? buy a new compressor, po.
