CHECK THERMOSTAT CALIBRATION A properly calibrated thermostat reduces your energy bills and increases comfort.
2.
CLEAN OR REPLACE AIR FILTER Dirty air filters can increase energy bills up to 40% an cause expensive equipment breakdowns.
3.
CHECK TEMPERATURE DROP ACROSS EVAPORATOR COIL A proper temperature drop of thirteen - twenty degrees is critical to staying cool and comfortable.
4.
CHECK AND CHEMICALLY CLEAN CONDENSER COIL A clean coil reduces operating pressures which extend equipment life and increase energy efficiency.
5.
CHECK AND ADJUST AIRFLOW Having the proper air going across the evaporator coil is key to getting the best comfort and dehumidification.
6.
CHECK AND TIGHTEN ALL ELECTRICAL CONNECTIONS Loose or burned wires can cause costly system breakdowns.
7.
CHECK VOLT AND AMP DRAW ON MOTORS This check can find problems inside the windings on the motor, giving us a chance to replace the motor before it becomes an emergency call.
8.
CHECK REFRIGERANT CHARGE Improper refrigerant charges reduce energy efficiency and shortens equipment life.
9.
LUBRICATE ALL MOVING PARTS Poor lubrication cuases drag on motors and drive shaft, thereby increasing energy consumption and causing premature motor failure.
10.
CHECK AND CLEAN CONDENSATE DRAIN (if necessary) A clogged condensate drain can create considerable water damage.
11.
CHECK START AND RUN CAPACITORS Capacitors arecritical to your system's performance.
12.
VISUALLY INSPECT SYSTEM FOR MINOR REFRIGERANT LEAKS (WHERE ACCESSIBLE) Refrigerant leaks cause loss of efficiency and shorten equipment life.
13.
CHECK TIME DELAY RELAY (if applicable) Extends life of compressor.
14.
CHECK CONTACTOR Contactor should mechanically open and close smoothly.
15.
CHECK MAIN 220 VOLT ELECTRICAL WHIP This check can protect against overheating of condenser components.
16.
CHECK COMPRESSOR TERMINALS Good power connections at the compressor terminals reduce costly breakdowns.
17.
CHECK DISCONNECT BOX AND FUSES Your power disconnect should be clean and dry and show no signs of deterioration.
18.
CHECK AIR CONDITIONER POWER BREAKER Your breaker should snap on and off with definition.
