Recently my the blower unit in my house has started kicking on every couple of minutes. It stays on for a few seconds (literally less than a minute) and then stops. A couple minutes later it comes back on.
I have a heat pump, however this is just the blower fan in the house that is coming on, not the cooling or heating functions on the heat pump.
I thought this had to be the thermostat so I replaced it today and the new one is doing the exact same thing. (Tried both a Honeywell and a Hunter).
Does anybody have any idea what could be causing this?
