I have read many articles both pro and con about voltage drops in

the extension cord was the problem. All I know is that removing the
extension cord caused both the a/c and the freezer to work well.


The size of the wire is more important than the length. If you used a
3' cord with 18 gauge wire it would be more of a problem than 100 foot
cord with #10 wire. Think of the wire as a pipe. You can only get so
much juice through it so bigger is better.
