My husband and I just purchased a home that is about 75 years old. We had an inspection done - the inspector said the furnace is working fine, though is 20-25 years old. We went to turn the heat on last night and nothing. The furnace doesn't kick on at all. We turned the thermostat all the way up - nothing. What should I be looking at to fix this? Thanks.

Is it oil,gas or electric? What make is it?

It is a gas furnace - I have no idea what make it is...

Is the pilot lit?

Pilot's lit...

Could be your gas valve or have you checked transformer. Also check all ecletrical connections an transformer and gas valve

Check all the breaker/fuses in the panel. He may have left one in the off position by mistake...
