HVAC Knowledgeable friends: Our Furnace is not performing up to par. It seems to be shutting off before the house is reaching temperature (and I just replaced the filter, so I know it isn't a matter of getting enough air flow). And most of the time the inducer motor will turn on, but then turn off before the blower fan kicks on. Does anyone have any insight as to why this might be happening, and is it user serviceable for someone who has just slightly more than a basic knowledge of how a furnace works?
I just want to avoid giving $763452376512354 to an HVAC company just so they can tell me my furnace is broken and needs to be replaced. Any help is appreciated.
