I have two duplexes that are up and down. There is only one gas meter and one power meter for two suites, so I pay the utilities. This has worked for the last year but lately the bills have been out of control. For Feb the power bill usage was double. What can I do? I am afraid if I ask the tenants to pay they will argue who is using more power. Is it possible that direct energy made a mistake? How can I get the tenants to pay? How can I solve this problem with out losing tenants?
