Furnace is a generic term for you heating system....some are gas....some electric.....technically still a furnace....electrically heated furnace.What furnace ?
Good advice.....especially if your heating is electrical resistive heating......Not a problem. It's what we live for here! :laughing:
Do you happen to know what type of heat/fuel you have?
Being that old, you may (if affordable) consider upgrading to a new system that is more fuel efficient.
I disagree.I didn't see any good advise here.Call an electrician.
