That depends on who does it and where and where you buy it too, anywhere from wholesale $2500 to $12000 retail.
It depends on the efficiency of the air conditioner. I have two 3-ton units for my home. One recently died and I replaced it with a more efficient unit. The new unit is 16 SEER, while the old was 12 SEER. In general, the higher the SEER rating, the more efficient, but you get diminishing returns as you go higher. For example going from 12 to 13 saves a lot more energy than going from 15 to 16. I have a whole house watt meter connected and measured both units after the upgrade to see how much more efficient my new one was. Below are the results. As you can see there is no easy answer to how much your unit consumes. 16 SEER - 2300 watts 12 SEER - 3400 watts
