      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. Unit Wiring – Inspected & loose connections tightened

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

6. 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.

7. Inspect Duct work

Ripped or disconnected duct causes higher utility bills and reduces efficiency of the unit.

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 if accessible and needed.

Improperly lubricated rotating equipment will eventually fail.

11. 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.

12. Air Filter – Replaced at customer’s option ($10 Value)

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

13. 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.

14. 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.

15. Cool-Tech Heating and Air Conditioning also provides 1 free pound of Freon / Refrigerant only if needed. ($45 Value)
