If you don't have gauges and know how to put in what ever coolant the system uses take it to someone who does and spend the coin. Or read up , get the tools and such and get to work. It is leaking and will continue to unless something is done about it. So it needs to be filled. It can be pulled apart, new rings installed but it could be the compressor that is leaking. Some florescent dye and a black light will help you or whoever see a leak. Again, not difficult but does take time and effort.
 
If the compressor keeps short cycling then it's low on freon aka you have a leak.
 
Not sure what an Ac pro gauge is? What are you high and low side static and dynamic pressures?
 
connect gauge to low side (drier)
start car and set ac at max and fan to high ..make sure fan is blowing at high speed from ducts..
if blower fan doesnt blow youll need to fix that before the a/c cant be serviced
is ac compressor clutch engaged or cycling ?
you need to make sure the ac clutch stays engaged to get a proper charge reading
unplug the round connector to the drier and put a jumper across the terminals inside the plug (a paper clip or cotterpin works just dont let it touch any metal )
set a flat screwdriver blade behind throttle stop to bring rpm up to 1200-1500
ac compressor clutch should engage and now you can read the low side charge pressure on the gauge
add refrigerant as needed, once the charge is near normal the drier plug can be put back and compressor clutch should re-engage
radiator fan should also be running to cool the A/c condensor core or rapid cycling will occor due to the

Sometimes a leak is indicated by oil residue. Look at all the connections and see if any show oil. Look at the condenser in front of the radiator. A hard hit from a stone can cause a leak. Typically a leak is the problem but it could be electrical too.
 
Wow..... Thanks guys. I appreciate the advise. On a personal note, thanks again Pace. You always have great advice.
 
Had similar problem after rebuilding my AC. I hope you purchase a decent compressor. All info above is a great start. Go purchase you a freon UV leak detector kit about 25.00 bucks, and you will be able to locate leak at ease. My leak was hidden very well . Remove freon fill cap on dryer, my schrader valve was stuck "bent" allowing freon to leak, but can't see unless you have light. I'm OLD to, and AC is a must especially in this heat.
 
Gentlemen. Thank you all for the advise. I'm going to purchase Freon detector. . never had one... New tool.
