There is a dye that is made just for that. Charge the system, per directions, and check for leaks using an ultraviolet light. Product is sold at auto parts supply stores, not sure if available at dicount stores.

A/c will not hold a charge. As I am charging the a/c I can hear it leaking

Take it to an accredited ac specialist shop as you have a leak in the system. It will be a waste of time and money to keep recharging it until the leak is fixed.

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.

This could be caused by a few items. If this is an old car I would suggest that you have the freon checked if they are at optimum level. Freon may be low that only the from part is working. Check also for leaks. AC shops would use a dye to detect leaks in the system.

If your car also works as a heater check if the heater part works. If it does work it may be the blend door that is not working. The blend door has motors and linkages which may have gone bad. A visual inspection is needed for this. If the heater does not work you may have to go back and check for leaks or wiring issues to the rear AC (also for those without heating).

Air Conditioner does not stay cold in my 1991 Honda Civic, freon does not hold, what is it going to cost me to get it working again?

Hi, it sounds like you have you have a leak. Bringing your car in for service for this kind of repair usually can cost several hundred dollars, 300 - 500 $. This problem is usually a leaky o-ring at one of the hose connections, so in order to find it you need to put a dye tracer in with the freon. There is possible ways that you could fix it your self. First go to your local auto parts store and pick up a can of freon with a sealer in it and give that a try, or you can go all out and get a kit that has what you will need to trace the leak, then you can replace the defective part and then re-charge the system. If you found this info help full then please click on the thumbs up button. Thanks,Bob

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.

    When i turn on ac it blows hot air

    Normally due to low freon. Also, notice if the a/c compressor clutch engages, as it will not if the freon is low.

    Put freon in compressor and for three days it cools after that the air is hot

    It sounds like you have a small, slow leak. I would get a leak detection kit that includes dye to put in the system, and a light and glasses to find the leak. Kind of sounds like an O ring leaking.

    1998 volvo s70 has a freon leak; mechanic/dealer checked under the hood and could not find the leak; says the dash would need to be removed to see where the leak is; Does the dash need to be removed to fix...

    Only if the leak is under the dash will the dash need to be removed. If he could not find the leak how does he know it's under the dash? LOL...Your mechanic is STOOPID...or playing you for a big repair bill. Halogen leaks (freon) are easy to detect with todays modern testing equipment. Get a second opinion on your car. There is no reason a leak can't be detected, if indeed there is a leak. Good luck...i hope this helps.
