    What does the condenser coils look like are they covered with any lint of grass clippings etc. Your inside filter is it clean? Do you see any ice build up on any of the copper lines? Get back with me and we can go from there. ken

One sure way to tell if your unit is doing what it is suppose to is using the box temperature method. Meaning inside the space your house and the supply coming from a/c. Take the temperature of the space take the temperature coming from the supply vents. Should be a difference of 18 to 22 degree's. Example the house is 75 F degree's the supply should be 55 degree's. Now if it is coming out 60 or 62 then you have a overcharged a/c and need to adjust the pressure's. It is a very fine line to get it perfect only a tech. guy could do that. Let me know how it goes. ken

Airconditioner cooling not workign despite three

I would check the system pressure. You can buy a leak detector. I would check all the fittings on the lines, around the compressor, condenser, and evaporator.

Car airconditioner not holding gas

you have a leak somewhere in the system, best bet is to take it to repair shop and have it inspected and repaired.
What ever you don't go buy a can of refrigerant with sealer in it. this will destroy the whole system and will cost you mega bucks to replace the entire system.
