If it needs a recharge that means it has a leak that needs to be fixed.
from what a HVAC technician told me, the coupling where the leak is coming from is hard to get a good proper seal.

Kind of sounds reasonable, like a water cartridge that is not proper fit/worn and you get small leaks.

Clean the evap and condenser coils , replace/or inspect filters , check the condenser fan lube if you can . run the ac if u see some ice building on the evap coil ,if so get the leak repaired and top up .

For all you suggesting to simply recharge the refrigerant, on a 15yo unit which likely uses R-22, the price of R-22 has skyrocketed to ridiculous levels because production has been phased out. I spoke to a local contractor last fall who told me the cost of a 30 pound bottle was approaching $2000CAD, and my 2.5 ton R-22 system which just died used 8lbs of it, so I'd be looking at over $500 just to refill it, plus labour.

There is virtually no maintenance on central ACs since they are a sealed unit. The only thing the homeowner can do is keep leaves and debris out of the unit, and hose it off.

Replace the system. Yeah it's expensive, but there's no point in trying to repair anything that old.
