Possibly theres a tiny leak on cars once they get older?
But than again... you get a recovery machine and pump out all the old r134a and than add new r134a to the right pressure.

No need to evac and refill, you have not replaced ony parts in the system. Get a low pressure side gauge and hose along with a small can of R134a, fill up to the point where you see 45psi on a 90 deg F day with AC running on high and all vents open, including rears. If you were to evac and refill you would need to add 2 oz of PAG oil for proper compressor lubrication along with the 14 oz R134a charge.
