Hello I hava a question abou my furnace. For the last week or two when I set the thermostat to a certain temp 73 the room temp stays at 64 ant the furnace hasn't been kicking on. Thee is a clicking noise that the furnace makes in an attempt to ignite but heat comes out. Besides calling for service anyone has any trouble shooting techniques or advice so I don't get taken to the cleaners. Thanks
Michael

You will need to get closer, much closer to the furnace. Tell us what's working and what's not working. It would help to know what kind of furnace you have,, the brand,what kind-electric-gas-oil,, and the model numbers, also is it just a furnace or do you have a heatpump

We will try to help, but need more info

Also let us know if you are able to bypass the tstat if instructed as to how
