It’s time for your fall tune-up to be sure you stay nice and warm this winter. The day time temperatures are still nice but falling and night time temperatures are down into the 40’s at night.
We will do the following check up on your furnace:

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 u0026amp; 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 u0026amp; 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, and prevents failure.

31. Test refrigeration metering device
Blockage or improper operations of metering device reduces cooling capacity, increases fuel costs, and shortens system life.

32. Measure operating pressures with gauges
Improper refrigerant charge can cause compressor shut down.
Check noise and vibration levels
Increases comfort u0026amp; extends life of equipment.

34. Check compressor amp draw
Ensures optimum performance; protects equipment.

35. Make final operations test
To ensure optimum performance.

36. Record system operation
For Home owner’s information and records.

37. Explanation of tune-up results
Explanation of work performed in tune-up and results.

38. Advise improvements as needed
To allow you to gauge effectiveness, efficiency and potential need for repair or replacement.

39. Conclude Transaction
Answer questions; collect for work performed, signature(s) on invoice, leave customer copy of tune-up, and make appointment for any additional work required.

Changing your air filter is very important. We change our’s out every time we get the electric bill, which I find is the easiest way to remember it.
