We need to replace one air conditioner and while we are at it, we thought it would make sense to replace the 27 year old Bryant furnace too (it works, but is not very efficient). The best price I've been quoted is a price of $9200 for a 3 ton American Standard 14 SEER unit with a 95% two stage variable speed American Standard furnace 120,000 BTU.

In addition, the second unit has a leak and instead of paying again to fix the leak (the unit is from 1990), we are considering replacing that one too with a 2 ton American Standard 14 SEER. The furnace it is connected to is from 2000 (Luxaire, about 75% efficient). One of the sales people said it did not make sense to sense to replace to replace the coil unless we also replaced the furnace. That's contrary to everything else I've heard, is he right? Also, should we consider upgrading the furnace now to a high efficient American Standard one? The AC and new furnace would be approx. $8800 (but I haven't fully priced it out). I can get 25% back on the work through a local utility incentive so it may make sense to do more work now.

We live in southern NY. What are people's thoughts on this situation, the systems and pricing? Thank you.
