Electrical Question Older House

[Kevin Taliaferro]

I have a tenant in an older house that is asking for additional receptacles to be installed in order to run a third ac unit. She says she has two running now and the temperature stays around 80. I believe the service is only 50A. I told her that I didn’t think it could handle another ac. It is the next day now and she is saying that the main breaker keeps tripping. Any suggestions on what I should do? I’m not too excited about rewiring an old house or upgrading the service unless I have to.

Thanks everyone for the suggestions. I do know the wiring has been replaced. And the temperature laws - I never even thought of that. I did do a search though for Ohio and there's no laws during summer. Only winter. I just don't see putting that much $ into the house for a few 90 degree days.
