Could be higher than normal voltage coming into the house.
I had the same problem in a house several years ago, bulbs blowing at an unheard of rate, then, all my appliances started "biting the dust", noticed that the oven temp. was higher than indicated on the knob.
Got my trusty voltmeter, the voltage at the plugs and sockets was running 138 to 140 volts!
Called the power co., they wouldn't even come out. They told me that they KNEW their lines were good, it had to be a problem on my end!
I'm no Electrician, but I do know that you cannot INCREASE the voltage without having in inverter, though you can decrease it with a transformer.
Sold the house within 2 years of buying it, so we just accepted it because it was temporary housing until we got the other house habitable.
