DIY & Home Improvement

If it's just the furnace blower you might consider squeaking by with just a furnace replacement for now. (assuming yours is a conventional set-up with the AC coil in the plenum above the furnace)

It would be nice to have a new efficient AC but sometimes the budget is the boss.

My friend just had to have a new furnace installed. She went with the furnace only and kept the old AC for now. She had to go high efficiency (IIRC 95%) because a cheaper low (80%)efficiency unit would have required an inspection and most likely re-lining of the 80 year old chimney. A 95% unit gets vented via PVC pipe through the wall (no chimney).

My friend's bill was $3300 installed for a Lenox 95%. Ottawa IL. This was, IIRC, a 150k BTU unit.

My neighbor in out condo just had furnace and AC done for $4,000 for a lower end 80% efficient unit. Don't remember the btus.
