Just had my 31 year old Rheem behemoth 60% furnace replaced with an Amana Amh95 furnace. New furnace is about 1/3 the physical size of the old one.
Total cost for removal of the old one and the new furnace (70,000btu) was $2500. Since this was in a crawl space under the house in tight quarters, I am relieved that the job went smoothly. The 95% new furnace avoided a big headache and additional cost since the code has changed from the original installation. The gas water heater and the old furnace shared the same chimney, which is not permitted now. The new 95% exhausts through a pvc pipe through a wall in the back of the house.
Will get $150 federal money back because of the upgrade. In Oregon there are additional rebates but these just apply to the variable speed blower model furnaces (which are substantially more expensive).
It still was a little painfull to write the two checks for $1,250.
Should add that an electrician friend and I prepped the area beforehand (about 3 hours total); removed some old wiring and old lamps, we added 3 new light fixtures (hvac guy said the good lighting helped with the installation), a gfi outlet (for the dehumidifier) and a separate 15 A dedicated furnace circuit with mc whip and disconnect and a 12 gage ground wire to the gas pipe. If I had to pay for this work, that would have been probably another $800.
The hvac guy and a helper took 7 hours for the job and there will be another hour for the inspection.
