Annual Inspection Plan

Our annual inspection plan is a preventative maintenance diagnostic that evaluates the condition of your power generator. All plans may be customized to fit your needs.  We visually inspect the fluid levels, battery condition, air inlet piping, exhaust system, belts and hoses.  We also check for leaks and broken parts.  We will  run your generator to determine fluid pressure, circulation and condition, airflow, temperature, vibrations, noises and charging system output.  We check the frequency, voltage and grease the generator end bearing, as required by the manufacturer.

American Air Systems provides repair,  maintenance and sales of residential generators.
