Auto or home???you'll need a manifold gauge,freon leak detector and be able to purchase freon/refrigerant to do the job,if your not familiar with the steps to do this take it somewhere(not trying to insult your intelligence,but if done wrong you can get hurt and the equipment is expensive for only using once in a while) if you do tackle it D.I.Y. good luck

Why isn't A/C working?


The AC unit on vehicles will not work if AC is not properly charged. Clutch will not engage. There is internal device that will not let the a/c start if under charged. System has to be evacuated and have fresh freon added to full capacity. Use leak stop and lubricants with the new AC freon.

Check all fuses/ relays for AC unit.

Use a freon gas sniffer/die tool to check for leaks.

Ac not working


The first thing to do is check the charge in the AC system with a set of AC pressure gauges that attach to the charging port, if the pressure is low or non existent then you have a low charge and this means you have a leak in the AC system. The leak must be found and repaired and then the system evacuated and recharged with the correct level of refrigerant

My air conditioner it doesn't turn on


The AC compressor will not engage unless the system is charged up with refrigerant, a low state of charge due to a leak will shut the compressor off. Have a set of gauges hooked up to the AC system and have the pressures checked to see if you have a leak. You must repair the leak before the system is recharged.

1987 cxr si ac not cooling


The most common cause of your lack of cooling is no or low refrigerant charge in the system, in most cases this is due to the front shaft seal of the AC compressor on the engine leaking, if it is leaking you will see oil deposited around the front of the compressor behind the drive pulley magnetic clutch. Of course there are other places that leak and other problems that cause lack of cooling, but check for a lost charge due to leakage first.

AC was charged but isn't staying charged


When you had it serviced was it checked for leaks, normally systems on have to be charged up every few years, unless there is a leak some place. Have your system leaked checked.

No ac, compressor is working, one of the ac lines to the firewall is nice and cold, but nothing inside the car. 2001 pt cruiser. Fan works and recirculation door is working.


Hi there
You have to check the gas charge on the a/c and then find the leak. If there are no gas leak and the gas charge is right, check the TX valve inside under the dash. Good luck with that.

I had my ac charged with freeon in June and a month later I have no ac. I don't think this is a compressor problem. Any idea where to leak could be?


Check to see if you still have freeon. If not you have a leak. Most auto parts stores sell freeon with a stopleak and oil combination charging system.

Ac not working right


If the system was workin enough for you to add freon and stop leak you may have overcharged the system and blew out the location of the leak to make it lose enough charge that it shut down from being low on charge. There is a low pressure switch that will stop the clutch on the compressor from engaging when low on charge. The hose connections have O-rings and the system needs to be discharged and the Freon captured to replace the O-rings. ALL O-rings should be replaced at once if that is the case. Look to see where the red dye showed up if you put in the stop leak. Normally the seal in the compressor is what starts leaking first. It sounds like your leak is bad enough that stop leak will not be the answer so you may have to break down and take it to a shop to check the system.

1997 Honda Accord AC works only if temp outside is below 80 +-


HAVE THE SYSTEM CHARGE CHECKED, SOUNDS LIKE YOU HAVE A LEAK AND A LOW SYSTEM CHARGE, REPAIR THE LEAK AND AND RECHARGE THE SYSTEM UNTIL THE LOW SIDE PRESSURE IS AROUND 28 PSI
