Trying to fix my own furnace before the cold weather comes

The cold weather is quickly approaching, but my furnace is not working.

I only have a few weeks before the cold comes, and I have no other way to heat my house.

I have always relied on this furnace, but the furnace has started getting old. The furnace is nearly 20 years old, so it is reaching its lifespan very quickly. When my furnace stopped working last winter, the HVAC technician told me that it could be fixed, but it would be better off if it was replaced. I wouldn’t have to worry about constant breakdowns with a new furnace. However, I didn’t want to purchase a new furnace at the time, so I asked him what needed to be fixed on the furnace and how much it would cost. The price that he gave was outrageous, so I took note of the piece that he said needed to be replaced, and I jotted it down. I waited for a while, because I didn’t see the necessity of replacing the part on the furnace during the summer, but I do now. I have taken apart my furnace and down everything that I could, but my furnace is not working. I just can’t find clear instructions online on how to fix my particular furnace. However, I don’t have enough money to pay the HVAC technician to fix my furnace for me. If I don’t figure out how to fix this furnace myself, my house is going to be very cold this winter, and I can’t afford to do that. I have a baby on the way, and I have to be a good dad and keep my baby warm with the heating system!
