Innova Aircon Maintenance

[number001]

If the system is not leaking try visiting Opti-Cool. Our Vios had the same symptoms but I didn't like the idea of tearing out the dash for a cleaning. Opti-Cool pumped out the old freon and oil and replaced it with a fresh batch. Cooled better than new when they were done. Check FB for locations.

I guess this opti-cool has the same cleaning concept as the Toyota Casa one I posted.

Possibly. But this works. Aircon is still cool after 3 years. No holes were poked anywhere. Their machine uses the existing high and low pressure ports.

If you're willing to go all the way then I recommend EEB Aire on Timog.

my un-touched aircon is still cool after 9 years.
i just wash the filter periodically.

i didn't have to clean my evaporator for 15yrs. until today. coz it's leaking.

so yeah don't touch the a/c unless you have to. my evap didn't even look very dirty coz it's got a cabin filter

Ganyan din gamit sa denso coolmate sa makati.. ibang brand lang ng machine..

Kung marumi na talaga evaporator walang magagawa yung machine unless remove mo yung evaporator sa housing.. kaya maganda talaga may cabin filter

Matagal ko na sinasabi dito na, huwag pagdalaw yun A/C unless meron sira. Lalong masisira yan sa annual cleaning.

i like the typo error.
what a letter's worth ...
heh heh.

i wholeheartedly agree.

Kaya mas ok kung maintain cabin filter cleaning... yung sa mitsu adventure ko walang cabin filter kaya no choice but to clean it baklas method... after 6 years ko pinagalaw kahit ok pa naman ang lamig kaso barado na talaga eh.. naibalik naman sa ayos nung shop..

I had our Innova's A/C cleaned and maintained just a few months ago. Nag-amoy goma ang hangin at nawawala ang lamig. May butas na ang evaporator sa harap kaya I have no choice.

Second time na yun ipina-service since binili bnew Nov 2012. Yung first time ay linis lang ng evaporator at fill-up ng silicone oil sa fan.

This time palit evaporator sa harap, palit expansion valve front and rear, at palit drier canister.

May kabigan akong mahilig magkutingting at makalikot ng sasakyan at ito ang mga napag-usapan namin about aircon repair and maintance.

1. Importante ang evacuation ng moisture at ordinary air sa AC system after ng cleaning etc. So siguraduhin may powerful vacuum device yung shop na pagdadalhan niyo. Karamihan sa talyer shops ay compressor ng ref ang gamit. Hindi enough yung power nito to suck out all moisture and air sa AC bago lagyan ng oil at freon. Pag nangyari ito, hilaw ang lamig.

2. Okay lang na hindi orig ang evaporator na ipapalit. I replaced mine with a China made ata worth less than 2K. Basta ingatan lang ng mechanic yung tightening ng bolts para hindi ma chip ang aluminum frame. Once nakabit na yun, wala naman masyadong force na magsisira sa evaporator.

3. Sabi ng huling AC mechanic ko, always use orig expansion valve kahit mejo mapapamahal ka. It is a precision device. Yung hindi orig, hit and miss. Kaya lang naman ito pinapalitan dahil hindi na maganda ang buga ng refrigerant pag tumatagal.

4. Yug last mechanic ko cleaned the condenser coil too using AC flushing liquid (5 cans). Yung refrigerant oil can build up sa loob ng AC system over time .Imagine yung loob ng engine na may nakadikit ng oil na ndi nman naalis during oil change. Yu nga lang mano-mano niya ginagawa kasi wala siyng opti-cool machine hehehe.

So far okay naman gawa niya pero this summer ko masusubukan ang tunay ng lamig ng aircon.

BTW, yung silicone oil sa fan ng Innova should always be checked kasi may effect din ito sa lamig na AC. Ito din ang bumubuga sa condenser ng AC kasi.

Guys I get it that it is better as much as possible not to let them tinker with the aircon system. I also believe in this principle.

But what to do if the aircon system is having a hard time (to cool quickly) especially after parked under the sun for a long time?

I mean I can see the performance has declined over the years. Lets says in the morning (when the car interior is cool from the garage), Before only #1 speed blower is needed and it cools the cabin even without the rear aircon. Now #2 speed blower is needed. Same case with the rear aircon (which is essentially a blower getting refrigerant from the front aircon).

Other than the one John_M suggested, What other "safe" or "safer" (than outright disassembly) remedies is out there?

Magkano kaya ang original denso ac compressor para sa innova diesel? Kasama na ang general cleaning ng ac system? Yng package price ng shop kasi ang offer nila ay P30k? Reasonable na kaya itong price nila?

kindly post all queries here regarding proper aircon maintenance of our beloved Innovas.[/QUOTE]

I'm going to hate the day my A/C would require servicing.

I've done quite a bit of changes under the dash, particularly around everything that has to do with the in-car entertainment. The thought of them tearing down the dashboard to get to the HVAC system makes me cringe.

I hope I wouldn't have to do it before I get rid of the car.

You have no choice naman but to let people tinker with your aircon system because of the required maintenance service or declining performance.

The trick is getting someone who knows how AC system work and how to properly service it.

For me the critical points are evacuation of the AC system prior to putting in the freon. One needs a powerful vaccum device to to this. Some even injects nitrogent when doing this.

2) The quality of refrigerant used. May maganda at hindi magdandang brands ng refrigerant.

Meron po ba kayong alam na maayos na car aircon repair shop dito sa mandaluyong or san juan area? Sira na naman aircon ng innova ko 2011 model. 2x ko na pinagawa sa speedyfix sa san juan last october '19 tapos binalik ko mar '20 tapos ngayon sira na naman. I spent 26k dun sa dalawang times.

Ok po kaya sa casa na mismo? Or sa denso mismo? Thank you sa mga sasagot.

When I was living in Pasadena dinadayo ko EEB Aire sa Timog. They have an FB page.

Tried the tipid talyer route and laging backjob.

Speedyfix is more of a basic maintenance shop.

26k spent, what did they do?

There are plenty of shops that specialize on car AC's.

Yup, sana diretso ka na sa denso nung una pa, maganda experience ko sa kanila both Alabang and Binan branch nila. And complete sila sa diagnostics.
