The following Special Discount for our 40 point
"check-up/tune-up" for cooling systems has a strict
time limit. The effective dates are 2/01/13 - 5/15/13.
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. |
Record system
operation |
For Home owner's information
and records. |
| 38. |
Explanation of tune-up results |
Explanation of work performed
in tune-up and results. |
| 39. |
Advise improvements as needed |
To allow you to gauge effectiveness,
efficiency and potential need for repair or replacement. |
| 40. |
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. |
