Yapoy good idea to have an A/C vent thermometer.
By the way Cathy, if you've seen the repairs the freon should come in a large, metal can yung tipong mini-Gasul, and not the Coke-in-can-sized cans because those are low quality.
When I had my A/C converted to R134a, it can now blow 5 degrees C at the vents when outside temperatures are around the high teens to low 20's. It takes a while talaga for A/C to cool the cabin if it's hot outside or if the car's been parked. Cathy it might be good if you could get a thermometer at the vents, and check the reading. It's best if you could take the reading at idle with the blower at minimum setting to see how cold it can really get.

I saw it and it looked like a mini gasul that they turn upside down when loading the freon. Does that mean that I got "latak" freon or is that the usual practice?
Where can I get the AC vent thermometer? I hope it's not expensive hehe

It's usual, the refrigerants aren't pressurized so it has to be flipped upside-down.

Cathy do you know how many pounds (lbs) were used to fill up your system? I don't know how much your system should receive but it's a very bad idea to overfill, and it won't cool as good if you underfill. If your car is originally an R12 system, and you convert it to R134a the newer legal type nowadays, you should load in a bit more but I don't know the concentration of how much should be added. This is because R134a is less dense (smaller molecules) than R12. However, R134a does not cool as good as R12 does, and R134a needs to run at a much higher pressure (again linked to its smaller molecular size) than R12.
So check if your system is filled with the correct amount of refrigerant, and find out what refrigerant you have (R12 or R134a). Chances are it's the latter but it's good to be sure of what you have.
I was checking the first page and it looks like you've had your A/C system repaired twice in the past and then just the other day you did. I think it would be best to follow Theveed's advice and have the whole system checked, it might cost you more but it will solve your problem. However since you mentioned your car has other problems it might be best for you to have your mechanic check everything, even the engine mounts and radiator leak if it hasn't been fixed.
The thermometer can be bought at hardware shops, a cheap dial one should suffice. The ideal temperature inside the cabin at the vents should be half of what the ambient temperature is. So if it's 30C outside, your cabin vent temps should be around 15C. It should even get colder if you're driving faster since the incoming air cools the condenser, together with the A/C and radiator fans behind the two.

April 11th, 2008 01:17 PM #45Its normal and you did not get "latak" freon...
Freon tanks are turned upside down so that the system will get the LIQUIFIED FREON it is normally done when the system have no FREON at all (during initial re-fill).. if TOP-UP only of freon, the tank will not be turned upside down so that the GAS FREON will enter the system.. this is the reason why top-up cost only 250 pesos while the full refill cost 1,000 pesos
FREON tanks are subject to VERY HIGH PRESSURE just like an LPG tank..these gasses becomes liquid under HIGH PRESSURE.. but when released they sublime as GAS

April 11th, 2008 06:09 PM #47well have you tried sticking a thermometer in your vent?? kasi ako na try ko na and it can really go as low as 0deg celsuis lalo na pag hindi nabilad yung auto sa araw like sa umaga or sa hapon/gabi, of course its "vent temp" pag labas ng hangin sa vent baba agad air temp nun to about 8deg celsuis pag dating sa balat mo.. technically it will just freeze pag singa mo kung ang surrounding temp mo is -5deg celsuis cabin temp. which is impossible.. siguro kung dun ka pupwesto sa loob nung cooling coil case eh pag singa mo magyeyelo ka talaga.. your cooling coil temp should be VERY COOL kasi malayo ang travel ng hangin before it reaches your cabin and your skin.. kung kulang ang lamig ng cooling coil hindi na aabot yan sa vent kaya pag labas eh mainit ang hangin..
additional info, MOST cars with climate control it uses an ELECTRONIC THERMOSTAT (resistive type you can see this inside the cooling coil case) which OPENS ( to turn-OFF the compressor) when the airconditioner cooling coil reached -5deg celsuis this is to avoid the cooling coil from forming FROST but not until the cooling reached -5deg celsuis it will continously engage your compressor..
unlike cars with ANALOG THERMOSTAT which you can control the ACTUAL temp of your airconditioner ot its frequency of turning on/off cycle.. Climate Control systems controls the temperature of your cabin by letting in some hot air (from radiator) to the vent when you slide the TEMP Controller near "hot zone" it does not control the TEMP by ACTUAL Reading unlike ANALOG thermostat that uses mercury for its TEMP control
Like TOYOTA they use analog thermostat for their vehicles like VIOS, REVO since hindi naman applicable sa pinas ang climate control...
In my kia carnival naka climate control din.. but i disabled my electronic thermostat and replaced with an analog thermostat.. in this way i can control my temp and also protect my compressor kasi mas madalas na mag "automatic" yung aircon ko hindi bugbog sa takbo...

The best way is ibalik mo sa gumawa para ma check nila uli. Overprice sila sa mga parts, ang serpentine 2k lang, laminated 4-5K. 96 corolla serpentine cooling coil original na nakalagay diyan.
Kung papalitan ng compressor ang brand new TRS compressor 12K pag tumaas pa diyan mahal na yon, pag replacement na compressor naman range 4-5K plus yun service.. mabuhay...

i suggest you isolate the problem first po. figure out what part should first be repaired.

imo, serpentine or laminated should still blow cold air. the real difference is when your car is parked under the sun, the laminated should perform better in cooling down the cabin.
anyway i had a similar experience before, new compressor, drier, but its still not as cold as before (7degrees max). when i brought my car to another shop, we found out that there was too much compressor oil.
