Calling Aircon Tech!

[2rm]

May Tsikoters po bang aircon tech para makatulong sakin i-diagnose 2011 innova ko? Ano po ba dapat pressure sa high at low side kapag patay ang makina at kapag idle speed? Dapat po ba na nagpapawis ang suction line malapit sa compressor pati na yung rubber hose? Normal po ba bubbles sa sight glass? Sorry po kung medyo maraming tanong. Gusto ko lang po muna kasi makasigurado kung talagang may diperensya aircon ko bago ko dalhin sa toyota dahil under warranty pa. Thanks!

Warranty naman pala eh, dalhin mo na

afaik, di normal yung bubbles sa sight glass. pero tama si sir shadow, mas ok na dalhin mo na sa casa. under warranty pa naman pala e.

Thanks sa replies, gusto ko lang muna kasing malaman kung talagang may diperensya kasi last time na nagpa pms ako (2 months ago) sinabi ko na parang humina ang lamig lalo nasa tanghali. Dati kasi kahit marami akong sakay, and nasa 10 o clock lang ang thermostat then nasa 2nd bar lang yung fan malamig na but ngayun magisa lang ako matagal bago lumamig with the same setting. Sabi ng SA ok pa naman daw ang pressure and walang problema. Pinacheck ko sa aircon shop sa labas kulang daw sa freon at baka may butas daw or leak. Kaya gusto ko malaman muna normal pressures and tamang way how to check para masabi ko sa SA na talagang may diperensya.

Kapag nasa casa kana bro tingnan mo ang guage manifold reading (yong kulay asul na guage yan ang nag reading ng low pressure) dapat nasa between 20 to 40 psi ang idle pressure na gumagana ang aircon mo at mas maganda kung aabot sa 35psi ang pressure nya, nasa top performance ang AC mo.

if the a/c system is dormant, both the low and the high side pressures equalize minutes after shutdown. the pressure varies with ambient temperature. using a pressure/temperature chart (you can pull this out from google) for r134a, the pressure of the system should be commensurate with the ambient temperature. if the pressure is lower in the chart than where it is supposed to be with the given ambient temperature, it is low on charge. yes, the suction side will have condensation as the pressure is low and consequently the temperature will be low. as far as the sightglass is concerned, you can not rely on this if the system is using r134a as in your case of a 2011 car. the sight glass has never been an accurate basis for the state of charge and worse with r134a because even if the system is properly charged, the sightglass will always appear cloudy.

yes, under warranty means you don't get to spend a peso. sagot lahat ng casa.. kahit ano pang sabihin o palitan ng casa, they should not charge you anything. and if you are not satisfied with the "repair", you bring it back and still not have to pay anything.
take advantage of it.

Thanks dr. d, , I know po na ganun ang warranty, kaya lang alam naman natin na karamihan, kung di man lahat ng mga dealer ay will try to avoid some warranty claims. Kaya ang gusto ko lang eh ma educate muna para meron akong isagot to prove my claim. Mahirap kasing makipagtalo na sasabihin ko lang na mahina lumamig magiging subjective, pero kung may pagbabatayan akong mga figures and symptoms medyo may pagbabasehan ako. Another thing na kung pwede ko pang makuha eh actual temperature ng air na lumalabas sa air vent. Im planning to buy infrared thermo gun to check and monitor na rin yung temp ng hangin na lumalabas sa air vent.

Thanks sir for the info, yung kasing tech na tumingin sa unit ko (outside casa) nakuha nyang pressure habang patay ang makina is 60 psi sa low side, around 2:00 pm yesterday so maybe ambient temp is around 30 to 35 deg C. Pagsaksak pa lang ng gauge "kulang" na kaagad ang sinabi malamang may maliit daw na butas kaya gusto ko rin malaman what should be the normal reading.Also sabi nya dapat pati raw yung rubber hose, hindi lang yung aluminum pipe sa suction line ang nagpapawis, di ko rin alam kung totoong pati yung rubber hose dapat magpawis ang alam ko lang yung aluminum pipe lang.

[dr. d]

an analog bimetallic temperature gauge will do. it's a lot cheaper, too. concorde stores...

Thanks doc will try to check, magkano kaya price range? sa sulit kasi may nakita akong thermo gun at P1,600

what!!! 200-500 kesos yung tinutukoy ko. it's a round dial the size of a large g-shock. but it doesn't give instantaneous readings. you have to wait a little, mebbe 1 minute..

if your ambient was around 86-95 degrees fahrenheit the pressure will be between 79 up to 85 psig with the a/c system rested and shut down for at least 10 minutes. your system is indeed a little bit too low of refrigerant.

a simple formula to estimate how much the high pressure should be on a good performing ac. (avrearge only)
R134A AMBIENT TEMP (DEG F) X 2.3
