Upon arrival technician found that the system had a failed 55 x 5 MFD capacitor, the technician replaced the failed 55 x 5 MFD capacitor. System working properly at this time. Technicians has concerns about how long the system will last and its current condition, system is clearly well over 20 years old and still running on R22 refrigerant, Systems refrigerant charge is fairly low but due to the amount of heat on the system because the system cannot shed any more heat due to the age, the charge is reading A little higher than it should be, tenant states that his system normally doesn’t start cooling until 5 PM, if the system loses anymore refrigerant system may need to be replaced. System working properly at this time, but not working efficiently at all.
