We have a voltage monitor we plug into an outlet in the kitchen ($25 at home depot). It's easy to see and just stays plugged in. As long as the voltage stays above 110v, I don't worry too much but it's a good idea to check when the air/con or other heavy load kicks on that it doesn't drop too low. It will dip for a second during startup of the compressor but shouldn't go too low and should quickly rebound to 110v or better.

Better still - invest in a surge protector of your choice that not only constantly monitors and displays incoming source voltage under load but also includes automatic low / high voltage shut off should that voltage fall outside acceptable limits, along with the ability to protect the A/C compressor by delaying power restoration by 2+ minutes. :B
