    Default Goodman AC unit (problems over the last 6 years!!)

    Model Number: unsure
    Brand: other
    Age: 6-10 years

    I have a Goodman exterior unit installed on my 1/1 condo that was put in by the builder when it was built in 2005. Since then I have had several techs come out and on the first occasion they replaced the compressor. I've gone through good times and bad times with the unit which eventually begins blowing warm air (bad times). I've had freon put back in the system but has proved to be a temp. fix. I've had a sealant put in and that held up for some months before the warm air again. I've been told there is definitely a leak somewhere but has not been found yet. I've also been told that it could be inside the walls which in that case, would need to run a pipe along the outside of the wall, all the way up to the third floor where my place is and in through the attic leading into my interior unit. My questions are... have these techs been playing games with me the entire time? what are the odds that the leak is coming from within the walls, and if so, is the only solution to run the pipes on the outside? could it be coming from the a coil? What should be my next step to find a permanent solution? Any and all help would be greatly appreciated!!

    Why was a compressor replaced ? If after it was replaced, and there is a leak was it done properly.
    Sorry but I'm old school and do not believe in adding sealants (sign of inexperianced technicians) JMHO

    apparently the comp. was bad and was replaced. i have not been told its been again, just a leak from somewhere. what should i ask to be done? is there some sort of full system leak test to determine where it is? what would be the fix?

    Refrigerant System should be pressurized with "Dry Charged" Nitrogen and refrigerant.
    Using a good "Electronic" leak detector it should be tested for leaks.
    System should be then evacuated to "Zero" psi, liquid and suction line driers installed.
    System should be evacuated through both high and low side down to 500 microns. Vacuum broken with Refrigerant and allowed to build to 25 psi static pressure. This refrigerant should be recovered and system again evacuated to 500 microns. Using a Micron Gauge will determine a leak or moisture (If the gauge rises rapidly there is a leak, slowly and there is still moisture). No movement and the system is ready to bo charged.
    Charging should bee done through a drier installed on the charging hose by recommended weight.
