HVAC repairs

So, I woke up this morning, and the house was around 52 degrees. Considering that it was -12 when I woke up yeasterday, I was concerned about the heat. I went down and checked the furnace right away, and sure enough while it was running, it would not light the burners (no fire). I have never worked on a furnace before, and really was not sure what to do. I found the manuals, got me volt meter and started going through the startup sequence. By 7:00 AM I had pin pointed it to a bad ignitor. Then starts the calls around to find someplace that was open on Saturday morning that would sell me a new ignitor.
I found two places by 9:00 AM, one who said they had it, and one who said to bring the old one in and they would check. Jumped in the car, stopped at the closer one, they had it, race back home, replaced it with Nellie's help, and yelled at hte top of my lungs "Let there be heat", and it was so.
I was really happy at that point, and now I am warm.
