COOLING

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.
