MAINTENANCE: A/C

1. CONDENSER COIL fins will be straightened and cleaned as required.
   VALUE TO YOU - Dirty condenser coils raise refrigerant pressure higher than needed, increase your electric bill.



2. EVAPORATOR COIL will be inspected and cleaned as required.
   VALUE TO YOU - Evaporator coils become dirty because air filters only collect a portion of the particles in the air. Even a small amount of dirt can decrease efficiency and increase operating costs. This is also a major cause of compressor failure. Customer should replace property sized air filters every month.



3. BLOWER WHEELS will be inspected and cleaned as necessary.
   VALUE TO YOU - Dirty blower wheels reduce air flow, causing longer operating time and increased cost. This problem can lead to comfort and compressor failure.



4. REFRIGERANT CHARGE checked by superheat / sub cooling method.
   VALUE TO YOU - A low or high refrigerant charge can easily go unnoticed and increase operating costs. An improper charge can cause compressor shut down.



5. AIR FILTER will be replace at customer's option.
   VALUE TO YOU - A restricted air filter can cause your air conditioning unit to waste energy and shorten the compressor's life.



6. LUBRICATION of motors and bearings.
   VALUE TO YOU - Improperly lubricated rotating equipment will eventually fail.



7. THERMOSTAT will be checked and calibrated as required.
   VALUE TO YOU - Improperly calibrated thermostats allow the unit to run longer than necessary. Every degree your air conditioning operates below 78 degrees can add 5% to 8% to the cost of cooling.



8. CONTROLS & SAFETIES will be inspected and tested.
   VALUE TO YOU - Controls and safeties that do not function properly can increase operation cost and cause other components to malfunction.



9. MOTORS will be cleaned and inspected.
   VALUE TO YOU - Dirty motors are less efficient and will fail sooner.



10. CAPACITORS will be tested.
    VALUE TO YOU - Bad capacitors can lead to compressor and motor failure.



11. CONDENSATE DRAIN will be checked to assure it is open.
    VALUE TO YOU - Algae can plug a condensate drain which can cause expensive water damage.



12. RELAYS AND CONTACTS will be inspected.
    VALUE TO YOU - Worn contacts and loose wire connections can lead to a motor or compressor failure.



13. UNIT DISCONNECT will be inspected.
    VALUE TO YOU - A worn or overheated disconnect blows fuses and is dangerous.



14. UNIT WIRING will be inspected and loose connections tightened.
    VALUE TO YOU - Loose connections can lead to a motor or compressor failure.
