Performed ac maintenance antelope, 27 yrs Goodman split system garage back yard. Found filter dirty and in upside down, recommend replacing more frequently. Client changed return grill, and wants to put filter there and remove filter inside blower compartment. Blower capacitor out of range still low. 10@8.8. Blower dirty, see pictures. Evap coil doesn’t have a secondary drain line just overflows onto unit. Condenser dirty coils on back side of unit especially bad. Washed unit. Top of unit still cracked. Compressor start capacitor 40@25.5 low. System appears to be low on r22 refrigerant see pressures, just below the freezing point. But with everything else going on won’t know for sure until all recommended repairs competed. With age of system and shape of system, recommend repair vs replace options. Went through entire ac system, cleaned and checked all parts.
