We have a forced-air furnace that we use year round to either heat or cool the house. In the summer months, it pumps cool air from a central air system. In the winter, it switches to heat by oil.
This year when we started the heating cycle, we noticed that we now get a hissing sound from our computer speakers, snow on one of the two TV screens, and noise on the home phone line. This only happens as the furnace fan cyles off (ie. as it is coming to the end of its blowing cycle).
Weird thing is the PC speakers are plugged into an isolated and protected circuit, so I am pretty sure it is not a surge or drain issue within the power lines. My first guess was some cabling is passing too close to the furnace and receiving electromagnetic interference.
Just wondering if anyone has had something similar and what they may have had to do to correct it. Thx.
