When I arrived I found condenser fan motor not running ,tested capacitor and found issue to be a bad capacitor which I replaced (45/5) once running I found system to be low on r22 with a vap saturation temp of 26 degrees which is below freezing so the evap coil will freeze over within a few days if ran consistently. I also found air leaks around ducts and drain line not ran properly so water drain out to back patio and also no float switches in case the drain line gets clogged . All this on a almost 20 year old unit . I explained all this to the home owner via phone (son in law resides here) and she is aware of these issues and only wanted to repair the capacitor for today .
