AIr Conditioner Maintenance & A/C Maintenance

Keeping your air conditioner operating at peak performance is essential not only for your home’s comfort, but for your energy bill too! Here are some of the most important items you should keep in mind throughout the year too keep your A/C running smoothly.

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.
