You Too Can Live in Paradise!

See for yourself the details of the most comprehensive Tune-up/Check-up in the industry.

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 — A restricted filter causes unit to waste energy
4. Routine cleaning of evaporator coil** — A dirty evaporator coil decreases efficiency and can lead to compressor failure.
5. Check condensate pan and fittings for leaks — A cracked pan or loose fittings can cause expensive water damage.
6. Check condensate drain** — A plugged condensate drain can cause expensive water damage.
7. Check blower motor amp draw — Ensures optimum performance; protects equipment.
8. Check blower wheel — A dirty blower wheel reduces airflow; increases operating costs and can lead to compressor failure.
9. Check blower motor stability — Unstable blower motors can cause premature failure of the motor and damage to the system.
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. Examine all electrical connections — Extends life of system; ensures safety.
13. Check total electrical consumption — Ensures optimum performance; protects equipment.
14. Check unit disconnect switch — Worn, overheated disconnect blows fuses; potentially dangerous
15. Examine parts for visible wear — Avoids costly service calls.
16. Check temperature difference across coil — Temperature difference can indicate proper cooling of system. Also affects comfort level.
17. Remove debris around outside unit — Promotes efficiency. Prevents damage to equipment.
18. Routine cleaning of condenser coil — Dirty condenser coils raises refrigerant pressures increasing electrical costs.
19. Check condenser fan motor amp draw — Ensures optimum performance; protects equipment.
20. Check condenser fan motor stability — Prevents costly service calls.
21. Check condenser fan blades for vibration — Prevents damage to unit and costly service calls.
22. Check crankcase heater* — Crankcase heaters that do not work lead to compressor failure.
23. Check reversing valve* — Improperly operating reversing valve wastes energy.
24. Check relays & contactors — Worn contactors and loose connections can lead to motor and compressor failure.
25. Check capacitors — Bad capacitors lead to compressor and motor failure.
26. Test time delay — Prevents unit from starting under load when power has been temporarily interrupted.
27. Check defrost assembly* — A defrost timer that does not work correctly causes loss of heat and can shorten life of compressor.
28. Check all controls — Extends the life, saves money, and prevents failure.
29. Check all safety devices — Keeps unit in safe operating condition.
30. Measure operating pressures with gauges — Improper refrigerant charge can reduce cooling capacity and efficiency.
31. Test refrigeration metering device — Blockage or improper operations of metering device reduces cooling capacity, increases fuel costs, and shortens system life.
32. Check compressor amp draw — Ensures optimum performance, protects equipment.
33. Check noise and vibration levels — Increases comfort & extends life of equipment.
34. Check and secure all panels — New systems have a blower door safety and will not operate if door is not properly in place.
35. Wax outdoor unit** — For weather protection and extended life.
36. Check water temperatures*** — Water temperatures are very important to the operation of the unit.
37. Check water flow*** — Proper water flow is vital to system operation.
38. Record System operation — For Homeowner’s information and records.
39. Make final operations test — To ensure system operation.
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.
