Aircon not so cold now - HELP

[Jimmyl]

Hyundai says continue and drive some more to see if gets warm.

 

Bubbles is suppose to be there as it will be difficult for the gas to flow without air-gaps. (from Hyundai)

 

Outside mechanic says to flush whole air con system. Costs $55.

 

Is that expensive?

 

Comments?

 

 

Thanks

Go to STAR automotive centre for their ROCOIL68

air con refrigeration compressor lubricants with

free air con gas Top up at $18 + 4%GST. (Voucher is

needed, you can it at the counter at STAR.

[Jimmyl]

Thanks.

 

By the way, what do I need the "air con refrigeration compressor lubricants"?

 

Normally only top up gas.

 

Thanks

[Rdtws]

The lubricant is just like your engine oil, it lubricant your

air con compressor. Since top up gas R134a is about $18, go for

this lubricant+gas = $18+4%GST.

 

For more info on the lubricant go to:

OKie.

 

Thanks

Cold scale from 1 to 10(coldest)

 

Stock (Cold 8)

added Super fuelmax. (cold 8) (day 1)

Then COOL grounded my car, more powerful and the aircon colder. (cold 9)(day 2)

added K & N filter (cold 9) (day5)

change original Champion plugs to NGK (cold 9) (day 10)

added STP Complete fuel system cleaner, the silver color one on a half tank of shell 98 and top-up full (cold 9) (day 15)

 

day 18 - cold 7 - got some wet, moist smell

now improvement mileage and still got half tank with STP.

hi jimmy

 

i think you air con is "icying" and the drain pipe maybe jammed. for the icying you will need to replace the a/c temostat, replace a/c filter. for drain pipe you just need to remove and flush it clean with water. for the a/c temostat go claim from tomato. for flushing you can DIY a bit and for the a/c filter it is up to you as it will cost you around 90+-...... i hope my 0.2 cent here can help in some way....

 

 

cheers

agree

[Jimmyl]

Many thanks to all.

 

I am a bit impatient.

 

I could not sleep well with this "problem" on my car.

 

Just went to car mechanic and do chemical wash plus top up - $55.

 

Expensive?

 

Aircon is now colder. But on hindsight, if really gas leaking, then LPPL.

 

Thanks

[Karen]

HE HE HE i can understand how you feel.... well you can try it out for a few days and see how..... if ok then you can leave ot alone....if not then you have to sent it back to tomato

 

cheers

Actually, the Komoco guys agreed to check at next servicing.

 

I thought possible to be gas leak or dirty so might as well try to troubleshoot 2 possible causes at the same time.

 

Any idea how long it takes for me to KNOW leaking or not. 500KM? 1000KM? I seldom drive, so distance better guage than time for me.

 

[Karen]

sorry for the late reply, er.... not sure on that but i think you be inform on what is going on, when you sent you car back to tomato

 

 

cheers

I park in sheltered car park all the time.

 

 

Any experts care to diagnose what is causing this downgrade of the aircon?

 

Is it permanet?

 

What can I do to improve it?

 

Thanks a million.

 

Hi Jimmy,

 

I'm also driving an Accent 1.5yr old.

 

As for the aircon, the unit is still strong after 1.5 years. I change my front grill to wire mesh type, hence more air-flow and cooling to radiator. Usually never less than 11o'clock position on the thermoset dial, and max fan speed is 2. Anything more than that is too cold.

 

As for the smell, it is fungus growth on your air con filter. As you know, Singapore is hot and humid. We often get into the car, start the aircon immediately, and when we stop the car, the aircon is still on. Hence the cool air is trap in the aircon duct. This will cause condensation as the air heats up. The moisture will deposit in your aircon filter and mould will start to grow. Take out your filter and you should see a number of mushroom growing...

 

Change your filter to aftermarket ones, only cost you $28.

You might want to install a voltage stabilizer. I did that and my air-con is noticeably colder even at the lowest settings !

[Jimmyl]

I am surprised you answered my 2 years old query. Anyway, I have added some buddyclub aircon additive and modded the aircon to have no hot air. Now aircon dial mostly on rightmost and fan on 1 for myself, fan on 2 for front passengers and 3 for rear passengers.

 

My model does not comes with the aircon filter so till this day I cannot find it. I know the description; "below the glove compartment near the centre console", still cannot find. Any photos appreciate.

[Jimmyl]

Thanks for the tip. I already fixed up the problem. ALso got HVS installed; POWER

while on the topic of aircon, wonder if someone who knows the physics behind aircon can comment on this:

 

aircon piping has a high pressure pipe (which heats up) and a low pressure pipe (which feels cold, has water condensate droplets). i'd like to get the aircon colder. do you think it makes sense to do thermal insulation of the low pressure pipe? this is because my low pressure pipe is not insulated and sits in the hot engine compartment full of hot air.

 

the gist of the question is: does the aircon coldness depend on the final temperature of the low-pressure pipe, or is independent of this value? physical laws say that the aircon's effect comes from the contents of the high pressure pipe dropping in pressure as it flows out into the low pressure pipe. PV/T boyles law. so using insulation on the low pressure pipe keeps the pipe colder, and makes the aircon work more efficiently?

[Vtim]

My 03 Focus also do not come with Aircon filter for internal circulation, though it comes with pollen filters for external circulations.

 

You can try to located the Aircon intake for the Compressor, normally behind the glove compartment, and DIY a filter (I used 3M Filtrete) to cover it.
