Warm Tanner's Winter: Help Replace Furnace

Hi! I'm Lindsay and that is my son Tanner next to me. He is 11 years old and such a good kid. I have been a single mom for 9 years.

Our 21 year old furnace finally pooped out on us. It actually got red tagged. We've been in a cold home with space heaters for a few days now. A new furnace is a lot of money and I apparently don't qualify for financing. I have had a rough year and nothing but bad luck with several things that financially drained me. I would be forever grateful for any help anyone can spare. My son doesn't deserve this all winter and I feel like a terrible mother. Thank you and Happy Holidays!
