Help on aircon

[Tigershark1976]

My altis aircon suddenly no cold air... so i guess the coolant must be low

Got a mechanic to top up gas... after that the aircon is fine again

mechanic claimed that cooling coil hv problem and say need to replace n quoted $420 and say will add filter for my car

(Altis no aircon filter)

 

any bros here has similar experience...

 

the only problem cooling coil give its either choked, or leak... Its something like radiator, where coolant cool the metal and when air passed thru the block, it will be cooled...

 

Did you installed airon filter? Altis (the previous version, current version not sure) doesnt comes with aircon filter. You need to install it yourself at workshop outside. If you didnt install before. It will give you problem after 3yrs to 7 yrs. The whole aircon block is choked with dust, road debris, leaves, insects and air cannot go thru it, thurs, its not be cooled. Forget about cleaning it.... cooling coil itsef its cheap.. the expensive part its the labour. The installer need to remove the whole dashboard in terms to replace the coil.... its min 1/2 day work for Altis (my dad replace it before for his Altis)

 

If you installed the aircon filter since day 1. Then its unlikely for the coil to be choked, in fact, when I replaced my cooling coil, I was surprise how clean it was after using it for 6 years... Since you have just refilled the gas, then monitor for a while to see whether the aircon gas leak. For altis, there is a small glass window along the aircon pipe. If the aircon gas is low, you can see plenty of bubble when aircon is turn on... very easy to monitor... If there is really a leak, your gas should be depleted within a week (I kena before).

 

If you are very much into ICE, make sure the aicon shop is doing a good job. After I replace the cooling coil, there are "aeroplane sound" and the ICE installer told me that either the interconnector, or speaker cables was accidentally shifted and there is signal interference... troubleshooting could be quite ex cause all the cabling works are hidden in the dashboard...

if it's still cold, monitor 1st.....

bro... that's what I said to my mechanic...

 

 

[Darkscale]

below happen in Sat and Sunday, other than this the aircon is working ok .. can anyone adv what cauese this?

compressor going to up the lorry?

 

01. On Sat, after dropping the kid and wife, go park car and the aircon subbenly no cold air, after i park the car, i on and off the aircon notice the comperssor didnt on .. but after a few on and off, the comperssor kick in and there is cold air.

 

02. Sun drove from west to east side to pick up friend for dinner, waited for about 10~15mins with the engine on as my kid are in the car. After pick up my friend suddenly there is no cold air .. so i on and off the aircon a few times while driving, and finally the aircon come back.

 

03. After maka, drop my friend off and was outside the car about 10 mins before we drove back, and the aircon suddenly no cold air .. so do the same trick again and the aircon come back again after few try on and off of air con.

 

by the way i driving 3 yrs old Latio and clock 107,000km.

 

 

Same experience before, connectors connected to the air con resistor melted and loose, or the Air con resistor is spoilt.

bro air con problem got a lot of cause one . there is realli a lot of possiblity . filter , blower , cooling coil , compressor , condenser , air con gas . n the ultimate s--t problem of all , WIRING . but tat onli applies for old car la . from ur case , most likely is the compressor spoil . but then again it could be u r low on air con gas since u drove it onli for 3 years . or maybe is the filter that is dirty alreadi . this one can bring to those specialise in air con one . they r veri experienced .

Try calling scrapyard or stockist to check price 1st.

 

 

U can actually ask the mechanic to do a water pressure test for ur evaporator cooling coil. He will remove the coil from the car, connect to a hand pump with a pressure gauge and pump it up to a certain pressure.

 

1) If pressure is holding after 5-10mins, evaporator coil is good.

2) If pressure is not holding, somewhere in the evaporator coil is leaking.

3) If u see water dripping from the coil as he pump up the pressure, then evaporator coil confirm gone.

 

 

If everything is good, ask him to do chemical cleaning for ur evaporator coil and re-install back.

 

 

A/C is a closed system, if no more refrigerant, means somewhere is leaking. It might not be the evaporator coil, need time to trace the various components and pipes with soapy water.

My car aircon got faint "hissing" sound in cabin and I can smell chemical smell from the air that's blown out.. Starts to notice this last week. The chemical smell is making me sick.. So I tahan for 2 days.. cannot stand it so send to Tomiko aircon service. The boss said aircon coil or something has leaked, cannot use OEM coil..must use original parts etc.

 

Actually I dun quite understand what he meant as I have no experience in car ac before as this is first time I encounter car ac problem after driving 2 car for 8 years.

 

I was quoted $750 for new parts and inclusive of labour. The boss say take 1 day to fix as need to dismantle entire dashboard.

 

Guys, is $750 reasonable?

depends on which shop quote this price.

[Kb27]

I replace my evaporator coil at moto-aire about $400.

I guess you should shop around.

[Chucky2007]

Tomiko Ubi quoted me.. Any significance?

Probably depends on your make/model. I know the labour for dismantling the whole dashboard ranges from $200-$400. Maybe depending on complexity and also whether any shortcuts are possible (ie many ws are known to cut the dashboard so that they can take out the cooling coil faster. Maybe can save 3-4hrs at a minimum and that lowers your labour costs. But of course, most drivers won't notice where they cut the dashboard ..... if you are not particular, then there is no issues, you can find the cheapest guy out there. But I'm not saying the cheapest guy will be cutting up the dashboard brackets though.....

 

Maybe if you can let everyone here know your make/model, then maybe other bros can share how much they paid for the same model.
