What should HVAC system cost in Chattanooga?

[Sean Lehmann]

I realize the answer is going to vary but does anyone have recent experience replacing HVAC unit?  I am looking at a new Goodman 2 ton 13.4 seer packaged unit for one side of my duplex in Chattanooga but was quoted over $7,000 which seems quite high to me from research Ive done.  Has anyone on here done something similar and remember the cost or have an idea of what pricing should be (ballpark)?  Thanks in advance for any help.
