I can't run an air compressor the lights dim even when the light in thr frig comes could this mean I have only a 100 amp breaker box or is this a problem with the power company ( they won't help)

Check your outside lines. It is possible that you have a broken ground wire on your incoming cable. Inspect them carefully.

What is the load (amperage) of your compressor.

100 amps is the minimum amperage required for a single family residence here in the U.S.A.

Look at your breaker box, it will tell you the amperage.
