    Thermostat - Check for loose connections that may cause unit short cycling. If possible, check or calibrate temperature readings.  
         
    Compressor - Check starting amp draw along with running amps. Compare to unit ratings. Look for burnt wires at compressor terminal.  
         
    Split Temperature - Measure temperature drop as air passes through evaporative coil. Ideal temperature drop should be approximately 20 degrees.  
         
    Freon - Check system pressures to ensure the proper charge on unit. If the system needs more than 2 lbs. do not add freon until leak is found and repaired.  
         
  image8.gif (63591 bytes)   Air Filter - Replace old air filter with a new filter. Look for any debris that could be restricting airflow in return. Try to inspect the face of indoor coil.  
         
    Condenser Motor - Check amp draw against max ratings. If needed, oil motor. Check for loose bearings or damaged fan blade.  
         
  image10.gif (71916 bytes)   Air Distribution - Ask customer how airflow is throughout the home. If airflow is restricted, examine supply and return ductwork plus plenum.  
         
    Condenser Coil - Check temperature split on coil. Should be approximately 30 degrees. Ensure coil is clean of debris and fins are not damaged.  
         
  image12.gif   Air Ducts - Make sure air ducts are clean and free of any growth. Look for signs that may indicate leaks in ducts. (Cold air in attic or insulation In ducts)  
         
    Blower Motor - Check amp draw against max ratings. If needed, oil motor. Check to insure blower wheel is clean and free of bacteria build-up.  
         
    Disconnect Box - Make sure all connections are tight. Look for signs of metal fatigue or signs of overheating (Bluish-Green). Replace if Necessary.  
         
    Evaporative Coil - Check and make sure both sides of coil are clean. Dirty coils cause poor system performance and early breakdown. Also poor IAQ.  
         
    Fuses - Check on fuse condition. If fuse is swollen or bad, check disconnect box for loose connection or leaks that may be permitting water inside.  
         
    Condensate Drain - Make sure drain is free of debris and bacteria growth. Check PVC for lose or cracked parts. Look for overflow signs (Rust).  
         
    Contactors - Check switch for worn or pitted points. Check part for possible discoloration or burnt wires. Replace part if worn.  
         
    Plenum - Make sure plenum (Elbow) is sealed correctly and that no air is escaping to the outside. 8 out of 10 elbows leak, usually underneath.  
         
    Start Kit/Relays/Transformers - Inspect all parts for loose wiring or worn out parts, and ensure parts are securely mounted.  
         
    Insulation - Check the insulation by blower to make sure it canŐt be sucked in. Also check tubing on suction line. Worn Insulation effects system efficiency.  
         
    Run Capacitors - Check microfarads on all caps. Recommend replacement if they are not within 10%. Check for oil leaks or voltage drop. Replace if bad.  
         
    Safety Controls - Check to make sure that the oil safety and high-pressure controls are functioning properly. Be sure that no one has disconnected them.
