For a good, not necessarily top of the line, brand. Cost of compressor plus installation. For a 3 bedroom average size ranch and basement.
I live in the New York city area.

It certainly will vary but the minimum I have seen is about $2500 in recent years. Labor, freon, and small parts (dryer, etc.) really add up over and above the compressor cost.

I had a new Payne (made by Carrier) central AC installed on a 3-bedroom rental house this spring. 2.5 ton unit, with a 10-year warranty.

It replaced an older unit, so this was not an all new installation.

It cost me approximately $2,300 (tax included).

We had a new furnace installed last year. Our air needed a new compressor - it was $1,000....3200 sf of living space.

Depends how old the one getting replaced is... if you need to change your inside airhandler coil as well as the outdoor condensor (some of the new outdoor units won't get mate to old coils) it would be more. I got quotes for 3000-4000 here in phoenix, AZ for a 13 seer 2.5 ton AC unit.

About 4500 for a 16 seer heatpump which replaces the furnace and the AC, and qualifies for the 1500 HVAC tax credit.

Default A/c Compressor Replacement

A few facts for everyone here:

Compressors are the most expensive component in an A/c, but even still they are not that expensive. A 3-3 1/2 ton, 12 SEER compressor costs a repair person [who buys wholesale] about $350-$450 (typical 3 ton COPELAND compressor used by most AC units). You often replace the dryer on the unit too (the big round tube soldered in on the line), that's another $50-$80, and usually the thing that causes your compressor to go bad is the condensor fan is not cooling the unit properly... that's another $50 - $100.

The controller boards and caps usually aren't replaced during a compressor replacement, but the sales person will talk you into it. Don't do it until they can prove those components are bad.

I'm not an HVAC person but I have replaced my own compressor, fans, caps, etc. The compressor requires freon which means you'll be REQUIRED to get a qualified HVAC guy to cycle your lines (3 times) after the compressor is installed.

Installing a compressor yourself:

Buy the same brand compressor, makes life a lot easier with the wiring and copper tube connections.

Use MAP gas and 50% silver solder, do not use flux. The soldering technique is the same for copper water pipes, no different.

Total cost to replacement pump, fan, and drier: $723. Average cost of a quote I received: $1900. THe unit cost $2600 and is 7 years old. Stupid, huh? If you want a higher SEER A/c, simple... SEER is rated at the PUMP, not the coil.. so, install a better pump with a higher SEER! Ta-da...

Best tip anyone can give you when it comes to an A/c unit: Change your condensor fan every 5 years no matter what. They are cheap motors and take about 30 minute to install. You can also just take them apart and clean the insides... all of them are brushless, they tend to go bad because dust and grim get in them.. 4 screws hold it together, remove them, pull the spindle out, wipe it off, put a little grease on it, put back together... you're good for another 5 years. If you can pump gas in your car, you can replace the condenser motor AND replace the capacitors... they are, in reality, no brainers.

I had a 3 ton unit installed for $2275 - I helped the contractor out by picking up the unit from his supplier because I work nearby.
