I hope I'm posting in the right place.
Here's the problem I'm having. When our electric furnance (its really an oil/electric hybrid) kicks in, our lights dim and the UPS devices that are connected to my computers all jump into battery mode and don't come out until the furnace goes off. This usually means the computer shuts down first. Now, this doesn't happen every time, but enough to be a real annoyance.
The house was built in 1968, and has a 200 amp service from that era. Its also a Medallon home, for those familiar with houses in British Columbia from that time.
Now, any idea what is going on, or if there is an easy solution to this problem?
