Air conditioning tune-up and safety inspection. Cleaned and serviced the condensing unit. Tested all mechanical parts. Found the capacitor lower than the acceptable range and the contactor is beginning to pit. The customer agreed to replace both parts. Used a 45/5 and a 1+shunt. Tested compressor amperage. Checked R410 refrigerant levels. Everything else was in an accurate, efficient working condition. This is the customer's last visit on plan and will need renewal in the fall. The system is operating, clean, and cooling as it should be at this time.
