Comparison of a "Spring Clean & Check" vs. "Enhanced Computerized Tune-Up"

Spring Clean & Check

Lasts about 30 to 45 minutes total from the time the technician arrives to the completion of the Cooling Clean& Check.

1. Check filter
2. Check the thermostat operation
3. Turn on air conditioner
4. Check the indoor coil metering device
5. Connect refrigerant gauges
6. Connect temperature probes on line set
7. Check voltage drop across the contactor
8. Check the outdoor electrical connections
9. Check the run capacitor load condition
   
   After 15 minutes of run time: 
10. Read & record suction pressure
11. Read & record suction temperature
12. Read & record liquid pressure
13. Read & record liquid temperature
14. Calculate system superheat
15. Calculate system subcooling
16. Measure voltage and amperage
17. Remove trash and debris from condenser
18. Clean the coil of the outdoor unit

Enhanced Computerized Tune-Up

Lasts about one to two hours total from the time the technician arrives to the completion of the Enhanced Computerized Tune-Up

1. Check filter
2. Check the thermostat operation
3. Turn on the air conditioner
4. Check the indoor coil metering device
5. Connect refrigerant gauges
6. Connect temperature probes on line set
7. Check the voltage drop across the capacitor
8. Check the outdoor electrical connections
9. Check the run capacitor load condition
   
   After 15 minutes of run time: 
10. Measure return air wet bulb temperature
11. Measure return air dry bulb temperature
12. Measure supply air wet bulb temperature
13. Measure supply air dry bulb temperature
14. Measure condenser entering air temp
15. Record refrigerant type
16. Record equipment SEER rating
17. Enter data into computer for analysis
18. Advise owner of results and if any corrections are required to increase efficiency
19. Test and record all voltages and amperages on complete cooling system
20. Test and exmaine all controls on outdoor unit
21. Examine and tighten all electrical connections on the complete system
22. Verify condensate drain line is draining
23. Remove trash and debris from condenser
24. Clean outdoor coil on outdoor unit
25. Test and clean outdoor fan motor
26. Inspect all duct connections (if accessible)
27. Test all safety controls on cooling unit
