Can't find any website that discusses, rates and prices central air conditioning units

You are at the complete mercy of your local heating and cooling contractors. Obviously, you should get multiple estimates, but it seems like you should be able to somehow get a ballpark handle handle on what is reasonable versus exorbitant pricing.

We need to get a 3ton split system replaced, using existing duct work, etc. I have 2 quotes that are miles apart. I don't know if one is too good to be true or if the other one is a complete gouge.

I have checked Consumer reports - they don't rate or have price info on central air. If you look at Lowes and Home Depot they just have forms to fill out for a contractor to call you. The manufacturer sites have no priceing info. This industry has a a heavy veil of secrecy.
