Inspected the HVAC system not cooling the upstairs. Tested cooling and heating from the thermostat. Measured the refrigerant pressures and electrical component readings. Inspected the safety and cleanliness of the system. Checked the air filters and ran duct load calculations. Found a failed dual capacitor and tested operation after allowing the system to run. Reported findings to the customer. Secured the new dual capacitor at the condenser. Cleaned both condenser coils. Rinsed with water, soaked in coil cleaner for 15 minutes and rinsed off the unit again. With manager approval, signed the customer up for a Homecare maintenance plan on the upstairs and main floor systems only.
