My neighbor and good friend is having an issue with his power at his house. His house is of similar age to the surrounding houses and his power use habits are similar in nature to the rest of the neighborhood as well. The issue is his power bill is 2.5 times what the rest of the block averages. Most houses on the block are paying around $180/month where his power bill is $450/month. He has switched to CFLs and it hasn't made a real difference.
He has contact the power company and they have tested their meter and even replaced it but they maintain that the issue is after the meter, somewhere in the house.
Could it be possible that AC is leaking to ground somewhere? What would you suggest to look for first? I have a good multimeter with a amp meter on it. The house was a RTM so there are two electrical panels.
If you need any specific information I can try to answer any questions you might have.
