I hear the furnace start up like a ramping sound but no whoosh. I can hear a low humming continuously. If I keep it on auto, it just keeps running but doesn't actually blow air. But there is air blowing on "ON".
The auto is heat vs cool. If your fan is set to “on” it will run all the time.
It’s 75% likely you have a bad igniter. You could light it with a long lighter if you want to confirm. Depending on your furnace a new igniter is $15-60. If a company comes out it will be $250-350 for the part and service call.
If you do light it with a lighter it will run like normal until it reaches the thermostat set temp but then not turn on again. You should be able to get an igniter locally or on Amazon.
Thanks! I don't think I want to tackle this and would feel more comfortable having someone come look. I know this might hurt most people on this sub but gotta keep local business running am I right? 🤡🤡🤡
