Irregular air flow from vents
Noise from the compressor
Water leak from air handler or furnace

AIR CONDITIONING MAINTENANCE CHECKLIST

1. Condenser Coil – Cleaned as required

Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electric bill.

2. Refrigerant Charge – Checked by superheat/subcooling method (Thermocharging)

A low or high refrigerant charge can easily go unnoticed and increase operating costs up to 30%. An improper charge can cause compressor shutdown.

3. Controls & Safeties – Inspected & tested

Controls and safeties that do not function properly can increase operation cost and cause other components to fail.

4. Relays & Contactors – Inspected & cleaned

Worn contacts and loose wire connections can lead to motor or compressor failure.

5. Crankcase Heater – Operationally inspected

Crankcase heaters that do not work can lead to a compressor failure.

6. Unit Wiring – Inspected & loose connections tightened

Loose connections can lead to a motor, control, or compressor failure.

7. Temperature & Pressures – Taken & recorded

An accurate record of your equipment’s vital data can indicate potential problems, which can be eliminated. A record will be kept with the unit which may reduce emergency service time.

8. Capacitors – Tested

Bad capacitors can lead to compressor and motor failure.

9. Unit Disconnect – Tested

A worn or over-heated disconnect blows fuses and is dangerous.

10. Lubrication – Application to motors & bearings.

Improperly lubricated rotating equipment will eventually fail.

11. Belts & Pulleys – Inspected & adjusted

Loose belts and worn pulleys decrease air flow, increase operating costs and shorten the compressor’s life. Belts crack and break with age.

12. Condensate Drain – Checked to assure it is open

Algae and dust can plug a condensate drain which can cause extensive water damage to your furnace.

13. Air Filter – Replaced at customer’s option

A restricted air filter can cause your air conditioning unit to waste energy and shorten the compressor’s life.

14. Voltage & Amp – Draw of the blower motor, compressor & condenser fan motors checked & recorded

Improper voltage and amp draw increase operating costs and can shorten the life of any motor.

15. Thermostat – Checked & calibrated

Improperly calibrated thermostats cause the unit to run longer than necessary. Every degree your air conditioner operates below 78 degrees can add 5%-8% to the cost of cooling.

16. Motors – Cleaned & inspected

Dirty motors are less efficient and will fail sooner.
