If you only see 220 at the outlet with no load in a single family home it is time to call the power company.
Power company only has to worry about the connection up to the meter and they automatically get a 5% deduction and are still in spec. Plus if it's hot out and the whole community is running air/con full blast, they will shrug at your complaint that it's down to 110v entering the house. They aren't going to rebuild the power grid for an issue that happens 2-3 times per year.
Depending on load and internal voltage drop from the power meter to the outlet, you can easily lose a few more volts before considering voltage drop on the 100ft extension cord.
To the OP: You may have perfectly fine voltage and it might not be an issue. My point is to check and keep an eye on the voltage. Don't wait for the smell of a burnt out air/con unit to clue you in that you have a voltage issue.
