Q: I have a 5-year-old electrically powered air conditioner on my roof as well as having an electrically powered, forced-air furnace. Lately, the blower motor for this system seems to kick on and off 24 hours a day every five minutes. I have the fan set on βauto.β So whatβs causing this?
A:Β It could be that you have wiring that is shorting out or you could have a bad fan control. You need an HVAC contractor to find and correct the problem.
