Depends on a lot of things - access most of all - but typically a new air handler (the housing, fan, and coil combined) is going to run $1500-2500 (installed cost) ballpark for that size unit, in all but very high cost areas - around $1000 of that is the likely charge for the unit itself, rest labor and incidental materials. Coil alone, IF an air handler where the coil is not integral with the housing, likely closer to $500 than $1000 for the coil, and commonly about $500-800 for the labor depending on difficulty - or what their "flat-rate" charge is.

If the failure resulted in loss of all or most all the refrigerant gas, might run as little as $250-400 additional for the system refill and tuning - or if you hit a vendor with very high gas charges might run $1000 or more for the gas recharge. In my book, anything over about $40/lb for R-410a or $60/lb for Freon, plus about a $150 recharge labor charge would be grounds to be looking at other bids.

You can find a lot of previous similar questions about coil replacement, about gas costs, and about the repair/replkace decision process - check in the Home > HVAC link under Browse Projects, atlower left.
