Line voltage too high?

It depends on the age of the home and the wiring methods used. It could be bad connections in junction boxes, etc.
In newer homes, it could be "backstabbed" connections used on the receptacles. When using a high current device, portable heater or window air conditioner, it's best to check to see if the plug or receptacle is running hot.
Maybe best, to get an electrician involved.

Yep, those lousy push-in or e-z wire receptacles suck. UL made a HUUUGE blunder listing those
Pull 'em out and pigtail thru-wiring if your box is big enough or replace with back-wired/screw-tightened receptacles - do not use anything that cost less than $1.50
