HVAC help

My house has a secondary furnace up in the attic that is 15 years old and is currently out of commission due to a bad circuit board. It's looking like it will cost enough to repair that I might consider a new unit. The furnace I have is not very big (45,000 BTU ). What should that cost to replace? My first quote is a shade over $3500 for a comparable unit to what I have. The quoted setup also includes the A/C coil installed with it so I can add Air Conditioning down the road. Is this a reasonable figure? I am told high efficiency furnaces will not work for this application because my attic is not insulated. Is that true? I looked into sprayed foam insulation and it's expensive. Advice appreciated.

I had a good experience with IMS Heating and Air. A second opinion and a free quote never hurts!

The high efficiency furnaces require a condensate drain because the exhaust gases aren't hot enough to carry the condensate out. The condensate drain can freeze and plug up in cold temps.
