Spring Tune-up Checklist

"HVAC: Heating, Ventilation, Air Conditioning"


Unlike "Murphy's Law" which nearly everyone knows that states "if a thing can go wrong, it will... and at the worst possible time" many people choose to ignore "The Law Of Moving Parts" that states "that moving parts someday will wear out and like Murphy's law, will wear out at the worst possible time, leaving you in the heat without cold. 40 Point Spring Tune-Up/Check-Up


The following Special Discount for our 40 point "check-up/tune-up" for cooling systems has a strict time limit. The effective dates are 2/15 - 5/15.


The complete description of the 40 point check-up/tune-up for a cooling system and the benefits that accrue are:


  Work Performed Benefits
1. Check thermostat Improperly calibrated thermostat affects comfort and operating costs.
2. Start unit Verify unit is operational before tune-up takes place.
3. Check return air filter Restricted filter causes unit to waste energy and shorten compressor life.
4. Routine cleaning of evaporator coil** Dirty evaporator coil decreases efficiency and can lead to compressor failure.
5. Check condensate drain** A plugged condensate drain can cause expensive water damage.
6. Check condensate pan and fittings for leaks A cracked pan or loose fittings can cause expensive water damage.
7. Check blower wheel Dirty blowers reduce air flow; increases operating costs and can lead to compressor failure.
8. Check blower motor stability Dirty motors are less efficient and will fail sooner.
9. Check blower motor amp draw Ensures optimum performance; protects equipment.
10. Lube motors & bearings Improperly lubricated rotating equipment will eventually fail.
11. Check belt, pulleys and alignment Avoids costly service calls, saves money on utility costs.
12. Check total electrical consumption Ensures optimum performance; protects equipment.
13. Examine parts for visible wear Avoids costly service calls.
14. Check and secure all panels New systems have a blower door safety and will not operate if door is not properly in place.
15. Examine all electrical connections Extends life of system; ensures safety.
16. Check unit disconnect switch Worn, overheated disconnect blows fuses; potentially dangerous.
17. Check temperature difference across coil Temperature difference indicates production and capacity of unit. Also affects comfort level.
18. Remove debris around outside unit Promotes Efficiency. Prevents damage to equipment.
19. Routine cleaning of condenser coil Dirty condenser coils raises refrigerant pressures increasing electrical costs.
20. Check condenser fan motor stability Prevents costly service calls.
21. Check condenser fan motor amp draw Ensures optimum performance; protects equipment.
22. Check condenser fan blades for vibration Prevents damage to unit and costly service calls.
23. Check reversing valve* Improperly operating reversing valve wastes energy.
24. Check crankcase heater* Crankcase heaters that do not work lead to compressor failure.
25. Check relays & contactors Worn contactors and loose connections can lead to motor and compressor failure.
26. Check capacitors Bad capacitors lead to compressor and motor failure.
27.  Check all safety devices Keeps unit in safe operating condition.
28. Test time delay Prevents unit from starting under load when power has been temporary interrupted.
29. Check defrost assembly* A defrost timer that does not work correctly causes loss of heat and can shorten life of compressor.
30. Check all controls Extends the life, saves money, prevents failure.
31. Test refrigeration metering device Blockage or improper operations of metering device reduces cooling capacity, increases fuel costs, shortens system life.
32. Measure operating pressures with gauges Improper refrigerant charge can cause compressor shut down.
33. Check noise and vibration levels Increases comfort & extends life of equipment.
34. Check compressor amp draw Ensures optimum performance; protects equipment.
35. Make final operations test To ensure optimum performance.
36. Wax outdoor unit** For weather protection and extended life.
37. Check water flow*** Proper water flow is very important to the operation of the unit.
38. Check water temperatures*** Water temperatures are very important to the operation of the unit.
39. Record system operation For Homeowner's information and records.
40. Explanation of tune-up results Explanation of work performed in tune-up and results.
41. Advise improvements as needed To allow you to gauge effectiveness, efficiency and potential need for repair or replacement.
42. Conclude Transaction Answer questions, collect for work performed, signature(s) on invoice, leave customer copy of tune-up, make appointment for any additional work required.


* Heat Pump Only ** If feasible and where accessible *** Water Source Only
