HVAC: Total system replacement? (furnace, AC, heater …

I have an HVAC system that dates to 1993. The gas furnace part is clearly in bad shape, was when I bought the house, and I knew I'd need to replace eventually. I want to get this thing fixed now, before the cold comes (I'm in Texas). I had a free inspection by an HVAC person who only tried to push total system replacement. After seasonal discounts, this comes to between 5-6K. I don't want to pay that much if I don't have to and the outside unit seems to be OK. Can I just replace the gas furnace part, or will this just cause compatibility or other problems?

You can change just the gas furnace part as long as the outside dimensions are close to what you have now. The A/C coils probably set on top. Not an easy job, but can be done.
