Some of the price difference could be between the SEER rating, brand of equipment, and scope of work being quoted.

R22 is still available albeit very expensive. Drop in replacements can be used in place of R22 at a fraction of the cost. Unfortunately residential contractors are befuddling homeowners into replacing the entire system. R410A systems don't come close to the operating effectiveness of R22 systems. Typically on a 95 degree plus day an R22 system will bring a house down to 71 degrees if desired. An R410A system will have trouble maintaining 77 degrees, given the same tonnage.
