Aircon di kinakaya pag mainit

[the_wildthing]

Ganito rin ang problema ko. Kaso iniisip ko unahing palitan ay condensers tsaka lahat ng hose. Mukhang yun ang pinaka-epektib na magpapalamig. Tama ba? O isama ko na rin evaporator? Tingin ko ok pa naman compressor at dryer.

Hindi kelangan palitan ang evaporator and condenser unless barado or may leak na. Besides, malaki magagastos mo. Kung hindi nakukuha ang lamig sa top-up ng freon, magpaflushing ka, leak test, replace dryer and expansion valve, then refill freon.

Nagpa cleaning ako kahapon, binalik sakin ng malamig (no. 1 na lang sa gabi kasi lumamig ng husto, dati no.2 pa) and medyo lumakas ang blower. Kaninang umaga, tinanggal ko yung resistor block(?) sa evaporator para macheck kung pinull down nga talaga nila (actually iniwan ko lang yung sasakyan, kasi may minor latero works pa), and malinis naman evaporator. Umalis ako ng mga 8am to MOA. Pagbalik ko ng mga 11am, may nakita na akong tubig dripping from the evap, i dismissed it as normal, pero yung lamig ng aircon humina ng husto, until halos mapuno na yung passenger floor mat. Pinacheck ko ulit sa kanila and barado daw yung drain, halos mapuno na yung evaporator, and nung nilinis yung drain hose eh sobrang lamig na tubig yung lumabas.

May dapat pa bang ireplace dito? kasi nung umalis ako ng shop (after declogging the drain hose) eh hindi pa rin masyado malamig, or nagkataon lang na sobrang init kaninang tanghali? Tignan ko tomorrow morning if ganun pa rin yung lamig nya.

hindi pa rin ganon kalamig sa umaga, ano kaya causes nito?

mga sir pag nag papalinis poba kayu ng ac pati condenser nililinis?

[Alfrance05]

I also experienced aircon problems prior consulting here.. Sir glenn advised me na palitan na yung condenser ng hyundai h100 namin since its quite old na (17 years) pero due to budget constraints i chose to have my condenser flushed, cleaned but to no avail, no improvements until such time na pati sa umaga kulang na yung lamig..
So i decided na to change the condenser, compressor, expansion valves, and drier and everything was so cold na kahit number 2 lang yung blower speed sa tanghaling tapat..
Also i've read somewhere over the net na may adjustments sa expansion valve.. Anyone expert on these? I got only little info on this..

pumunta ako ng Tagaytay kahapon, crawling in midday traffic, a/c was operating dismally, pero at highway speeds sobrang lamig. just noticed that the compressor cut off at high RPMs (3k), pero nag engage naman when i slowed down. bale pag traffic, halos hangin na lang lumalabas, pero when cruising lumalamig. ano kaya problema nito?

last thing done with the system is having the evaporator cleaned and system recharged. may pinhole leak(s) ako dati pero it was patched up. 1 day lang malamig at idle, that day eh bumara yung outlet ng evap area pero it was fixed. kinabukasan eh hindi na malamig at idle, pag tumatakbo na lang.

well, you obviously have to visit the aircon fixit shop again. anything less than that, and we are just going around in circles, guessing..
one thing i remember experiencing about pinhole leaks.. having one is a show of age. it means others will follow in quick succession. that's why i recommend replacement and not repair.
good luck.

Hi Guys,

regarding sa aircon.

Meron bang connect ang radiator sa lamig ng aircon ng kotse? Ang pagkakaalam ko wala.. Pero just to be sure nagtanung na ako dito..

Bakit ko natanung?

Kasi simula nung na overheat ang kotse ko at dahilan nun ay kawalan ng tubig at coolant ng radiator ko.. Pag tapos na matumal na ang lamig ng aircon. hindi na ganun ka lamig kahit napaayos ko na ang radiator.

Sabi ng shop maaring sa radiator daw ang sira magpalit na daw ako kahit daw evercool radiator maganda na daw un.

Kaya eto nag tanung ako radiator ba tlga ang dapat palitan or niloloko lang ako nito ni kuya manong?

Thanks guys!

Sir,
Pa check mo na lang sa reputable aircon service, baka nagkataon lang na nasabay sa radiator problem. Pa check nyo na rin mga cooling fans.

[dr. d]

some EFIs shut off the compressor when engine temp reaches abnormally high levels, as when overheating for whatever reason.

maybe your radiator water dried up because of under-performing aux fans.. this means: 1) it will recur unless the under-performing fans are repaired or replaced; and 2) since these same fans cool your aircon, your aircon will also under-cool until the fans are fixed..

i used to have heating and cooling problems (sentra). i thought my aux fans were ok, because they still spinned and pulled cooling air in.. until the mechanic showed me just how strong these fans should be in moving the air.. things improved vastly when i had my "still-working" fans replaced.

[non-vtec]

Just a tip. If everything seems to work on your AC, but you're not satisfied with the cooling, apart from the aux fans, try to blow compressed air to the condenser. This will somehow unclog the dirt accumulated through the years. It is often neglected kaya its a good thing to do at least every oil change.

most vehicles pag more than 10 years na hindi na basta basta nakukuha sa linis at flushing ang condenser.... then dapat din ni katiting na moisture walang matitira sa loob, ang dapat gawin eh i-oven yung condenser mo... then pressure test....

eds ac shop lang ang shop na alam ko na kayang malinis.... or palitan nyo nalang ng bago...

yung eds ac shop... may 5yrs. na exp. valve ko hindi pa din nila pinapapalitan.... adjust lang nila... may bilang po silang ginagawa... dati may computation pa akong nakita... pinalitan nila kasi ng ibang exp. valve....

[ParticleX]

gigive up na ata yung aircon system ko after 2 decades, hindi na naga-automatic yung compressor. are China replacement compressors good? Anong recommended nyo na compressor? >10k budget sana for compressor, cleaning, and recharging... preferably bnew compressor sana. Am near Evangelista so kung may shops kayo na recommended doon, please advise. btw Terrano JDM pala

I'm impressed with "manong" marketing for that brand.

The principle of A/C cooling when it comes to the 2nd stage (condensation) is that you require surface area, pressure and airflow.

If say a conventional radiator attempts to provide more cooling capacity, what common designers do is simply add on another row. On the radiator end, you do add capacity but at the expense of overall system airflow (airside pressure drop) and space.

Your condenser, fundamentally isn't getting as much airflow as it should, lowering your A/C system capacity, hence your engine works harder to maintain interior cabin temps, your car consumes more fuel, and net loss overall in terms of performance.

So as far as the airside of the equation is concerned, you wouldn't necessarily want to upgrade your radiator willy nilly. Checking your fans and making sure your condenser and radiator cores are clean could make a simple and economical difference in your vehicle's performance.

Update lang,

More than six months ago, i decided to replace the defective compressor with a surplus unit. Totaled 7k plus since i decided to replace expansion valve and drier na rin,they gave three months warranty for the comp. after four months, nawalan ng lamig and turned out to be the Pito, may singaw. So refill lang muna, 600. Then after two months, an o-ring leaked, so mga 2k din ang cost kasi pinasabay ang cleaning. 10k plus na rin ang nagagastos, pero ngayon pag traffic sobrang init.

Since magsa-summer na, and diagnosis reveals that the compressor is going south, i decided to replace it na lang, eto nagastos ko:
Sanden SD5S14 (508) Genuine Singapore - 6.4k
Receiver/drier - 100
Manual thermostat - 350
Compressor oil -150

Bought it from 1Rotary at Evangelista. Orig price nung comp is 7k. Bought the parts to our trusted mech and pina full flushing ko lahat ng parts, and sya na rin nagpakabit ng bracket. Feels like a brand new car na, sakto kasi lapit na mag summer. Baka lalo pang lumamig when i will change my tints

Yung lumang shop ko na pinagawan is RGL Evangelista sa tapat ng INC church, wag kayo dun (sila din source nung surplus comp). Quote nila dati for exp valve and drier is almost 2k pero yung drier eh 100 lang amp parehas lang din naman.

Meron din kups na shop sa Banawe, forgot lang kung anong pangalan. Sila dapat kasi papagawan ko kasi sagot ng fleet card. Sabi ba naman di nila kayang awin kasi Subic daw, at kahit palitan lahat ng parts eh hindi daw siguradong lalamig. Tanong ko kung anong solusyon, palit daw sasakyan, bastards

[ParticleX]

Regarding pala dun sa compressor, it is indeed genuine, pwede ma check sa Sanden website. Medyo weird lang ang warranty dun, sabi nila yung China version (4k) may three months warranty, while yung Singapore eh no warranty pero pwede ibalik sa kanila

Kainis talaga yung banawe shop na yun amp

^^ saan mo pinagawa yung compressor mo?

^^ saan mo pinagawa yung compressor mo?

Pina-install ko lang po sa aking trusted mechanic

sino siya or saan ba yung trusted mechanic mo? or kung pwede ko siya ipakabit dun sa recommended na aircon shops mentioned sa ibang thread dito?
