This can be a difficult question to answer. It depends on a lot of factors. The size of the place you live in, the type of heat, does it have central air and do you use it and are you both at work during the day or does one of you stay home. With out knowing all the details I would really hate to give you a number. I know I have a place in Mont Alto ( which has higher rates than Waynesboro) and it is currently running an average of $60.00 per month for 3 people. Hope this helps some. One more note if you have an address you can get a monthly average from West Penn Power for that address.
