Charge the system with a leak finder. It comes with yellow lens glasses and a blue light. The chemical will glow when the light is shinned over it and your wearing the glasses. Leaks often occur where hose connections are. Replacing the orings usually does the job.

Ac condenser stopped working what are possible solutions


I am going to assume you meant AC Compressor as the condenser is basically like a radiator in that it cools the freon.

I would say that your freon is probably too low to kick the compressor on. This could be simple as adding some freon (With Leak stop(just to be sure)) would get it working again. The question is, why did it get low? Could be just age and it needs a little freon but usually means that there is a leak somewhere (Hopefully it is not the condenser leaking). Some leaks are small enough that you just need to add freon every month or so but they eventually get bigger. Look for oil around the AC connections and hoses. Could be an O-ring that has gone bad. Hopefully it is simply low on freon.

Undefind Freon leak


that is a very fast leak. try using UV dye leak detector. color of this dye is bright green and will be show at the leak source. a UV light is also helpful so you can see it better. you can buy this at any auto parts with freon mixed with it, with this leak you should see oily trace at the leak area, don't forget to recharge compressor oil after your repair.

My air conditioner works but does not cool . i have added freon the last two years and fixed the problem ,did the same thing this year but did not help .


When self adding freon after it leaks out you get air trapped in the system. After adding freon a couple of times the air expands not leaving room for the needed freon. To continue adding freon with air tapped will knock the compressor out pretty quickly, there's not enough room for both & the air is keeping the freon from being able to cool properly give the false indication of being low on freon. The freon you are adding has the dye added to assist in finding the leak since freon does not evaporate nor dissipate it its being leaked out. A black light will assist locating the leak. The best thing is to have the unit checked & serviced by a mechanic...he'll charge about $ 150.00 to check for leaks, remove the old freon...his machine will tell him how much air its trapped in the system by how little freon is removed. For the service fee he will replace valves & gaskets, where needed, correcting most leaks. After sucking the system down & recharging the problem should be corrected.

Y mom has a 1996 buick century and she keeps taking it for freeon. The air blows cold for a while the it doesn't . Is there a leak or is the garage missing something. Thanks


it definitely sounds like a freon leak in the system, once a garage checks out the a/c system, they normally put in a dye in the system, and this will show where the leak is, and after the leak is fixed , they will refill the a/c with the proper amount of freon, "you are wasting your money and freon, if they don't fix the leak 1st, before adding freon, hope that this information has helped you.

My AC wont blow cold. As soon as I put freon in it, it blows cold for about an hour, then hot again. My friend told me that the orifice tube in his car needed to be replaced because it was convertine the...


Sounds like you might have a leak. If you charge the system and works for a time ,(hour, week, year) and then quits it sounds like perhaps the freon is leaking out somewhere. Freon does not ever get converted to air. Freon is in several states of existance while it is in your system. It is a high presure liquid, high presure gas, low presure liquid, and a low presure gas, but it is still always freon.
The valve your friend is talking about is called an expansion valve. What it does is to take the high presure "liquid" freon and allows it to pass into a low presure zone called an evaporator at a regulated rate. When you take freon at a liquid state high presure condition and expose it to a low presure environment it "evaporates" ( thus the name evaporator) and it gets very cold when it does this. This is where the cold air you feel coming out of the vents is made.
But the freon is in an enclosed system. By this, I mean it is never exposed to air, moisure (water), or anything else. I goes through all of these changes while inside this enclosed system.
Therefore, if the enclosed system is good then the amount of freon inside it will not change. If the amount of freon doesn't change then adding more will only make things worse.
I would suggest having the system checked with a hologen leak detector and/or system dye to find the leaks. Remember, if you have to add freon, then the freon that was there before must have escaped from somewhere.
Find a reputable shop to check the system for leaks. If it is leaking bad enough to run low in a hour it should be an easy to find leak.

How do you add freon to a 1996 nissan maxima?


It is the same as with any other car. The freon must be added through the low side service port. If the freon is low, it means that there is a leak. It is recommended that you find and fix the leak before charging the system with more freon that will just leak back out.

How is the best way to recharge freon in the ferrari 328.? any common point of freon leakage?


All vehicles will leak a miniscule amount of freon from the seals throughout the coolant lines, you can use a leak detector additive when adding freon or use a freon gas leak detector to find any substantial leaks in the system by guiding the probe around all the components while the vehicle and ac are running. You could use a heldheld freon charger with a built in pressure guage provided you have the correct fittings, otherwise I'd recommend having both your low/high pressure sides monitored while adding freon and making sure your compressor is turning on and off properly as the high pressure side reaches its peak.

Air condtioner has a bad smell causing headache


Whether as a gaseous or liquid coolant, Freon aids in refrigeration, air conditioning and maintaining aerosol contents under pressure. Not only can this toxic chemical expose the earth to excessive ultraviolet rays, but the substance can also sicken those who inhale it in an enclosed atmosphere.

Detecting the signs and symptoms of a Freon leak will protect lives, ground water and air quality.
Cardiac arrhythmia can signify the presence of leaking Freon. A person without a history of irregular heartbeats might suddenly detect heart palpitations and faulty blood circulation upon exposure to a Freon leak. The blood circulation problems may also lead to numbness in the limbs.

General Illness
  • A Freon leak can cause nausea, headaches, bouts of regurgitation and general disorientation. Confused thinking and trouble walking or coordinating movements also may result. Severity of illness depends on the amount of Freon released and the length of time exposed. A fire department can provide solutions and guidance for anyone detecting a Freon leak and suffering from its effects.

    Adding freon to the air conditioning where does the freon go?


    look for the thick pipes vs. the thin pipes and a quick connector that goes on to the hose that fills the r134a via a can of freon.

    Or, do you mean, where is the freon leaking out of? The freon leaks out of o-rings, seals, and possibly the compressor.

    I had a compressor changed in my 1990 Cadillac Deville because it was leaking there. This is a common problem on older cars.

    Good luck.
