I havent been active in HVAC for a couple yrs now but yes those prices seem reasonable.

Before I got my certification i had to replace the outside unit on my house (4-5 yrs ago) and it was a 3 ton unit and had it all done for $2400 in the summer time so i was happy.

There are 2 ways to figure how much of an AC unit you need..there is the Load on the unit and then there is the general 380-400 sqft per ton.

the 1st you can look up here--http://www.ehow.com/how_4883462_calculate-air-conditioner-size-house.html

a 2.5ton unit given the sqft of your house will work better then a 2 ton unit in my opinion.

as for changing out the complete system...eh..thats a judgment call..its not a bad idea to have it all replaced at one time so that there are no worries and everything is designed to work together but thats not always an expense we can handle.

One other option--call local tech school(s) and see if the HVAC instrutor will have his students change out the Compressor...or if another Company will..
