1.) Thermostat – Check for loose connections that may cause unit short cycling. If possible, check or calibrate temperature readings.

2.) Split Temperature – Measure temp drop as air passes through evaporative coil. Ideal temperature split should be approximately 18-22 degrees.

3.) Air Filter – Inspect air filter. Look for debris that could be restricting airflow in return. Try to inspect the face of indoor coil.

4.) Air Distribution – Ask customer how air flow is throughout the home. If airflow is restricted, examine supply and return ductwork plus plentum.

5.) Air Ducts – Make sure air ducts are clean and free of growth. Look for signs that may indicate leaks in ducts. (Cold air in attic or insulation in ducts).

6.) Disconnect Box – Make sure all connections are tight. Look for signs of metal fatigue or signs of overheating (Bluish-Green). Replace if Necessary.

7.) 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.

8.) Contactors – Check switch for worn or pitted points. Check part for possible discoloration or burnt wires. Replace part if worn.

9.) Start Kit / Relays / Transformers – Inspect all parts for loose wiring or worn out parts, and ensure parts are securely mounted.

10.) 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.

11.) Compressor – Check starting AMP draw along with running AMPS. Compare to unit ratings. Look for burnt wires at compressor terminal.

12.) Freon – Check system pressures to ensure proper charge on unit. If the system needs more than 2 lbs. Freon will not be added until leak is found and repaired.

13.) Condenser Motor – Check AMP draw against max ratings. If needed, oil motor. Check for loose bearings or damaged fan blade.

14.) Condenser Coil – Check temperature split on coil. Should be approximately 30 degrees. Ensure coil is clean of debris and fins are not damaged.

15.) Blower Motor – Check AMP draw against max ratings. If needed, oil motor. Check to ensure blower wheel is clean and free of bacteria build-up.

16.) Evaporative Coil – Check and make sure BOTH sides of coil are clean. Dirty coils cause poor system performance and early breakdown. Also poor IAQ.

17.) Condensate Drain – Make sure drain is free of debris and bacteria growth. Check PVC for loose or cracked parts. Look for overflow signs (Rust).

18.) 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.

19.) Insulation – Check the insulation by blower to make sure it can’t be sucked in. Check tubing on suction line. Worn insulation effects system efficiency.

20.) Safety Controls – Check to make sure that the oil safety and high-pressure controls are functioning. Be sure that no one has disconnected them.

21.) One pound of freon included (if needed)

22.) Clean & rinse Outdoor coil (some ristrictions apply)

23.) 1/2 hour of repair included  ( replace thermostat, controls, repair wiring, etc...)
