My furnace seems like it went out. It got very cold. I set my thermostat on 90 to see if I can hear the furnace come on but I didn't. I felt the vents to see if they would get hot but they didn't. I don't know if the pilot is lit. How much do it cost

Excellent service. If you don't know about furnaces, don't fix it yourself and make a worse problem. You get what you pay for.

They are high, you should first try and fix it yourself first check to see if there's a pilot on if not it could be the thermal coupling that's bad if you cannot light it and if the pilot light is on it would be your thermostat upstairs that's on the wall these are cheap fixes thermostat can run any place from 20 to $100 or more thermal coupling can cost around 5 bucks really easy to put on
