If you are leaking freon, then there is a small crack or break somewhere in the system. Either from age (old corroded unit) or from stress (someone having bumped or stressed the lines or unit)
If you are leaking water at the furnace area, then the condensate is not draining out of the evaporator (A-coil) due possibly to a clogged drain tube. All evaporators have drain tubes.
If your lines are leaking (water all over them) then the air moisture is condensing on the lines and the line (usually the thicker one) should be insulated with foam pipe insulation.
If it leaks it leaks. Central units are self contained with no external rotating shaft seals to leak. If the tech came out and added freon without detectng the leak, either he did exactly what you directed, or he is a BS artist hoping for a repeat job.
Yes.
You cant
why dose all the antifreeze leak out when you turn on the ac from your 2000 honda accored
Only if it has a leak - in which case you have to get the leak repaired first.
You can find a Freon leak in a home Ac unit by using a leak detector. These instruments are capable of detecting trace amounts of Freon and pinpoint leaks.
you have an AC leak
yes there is a seal on the front of compressor that can go bad and leak freon.
No, the leak is propably the compressor shaft seal which is behind the clutch.
how do you check freon on central ac and what should the guages read.
It can, in some cases.
No
