Trying to figure out the “real” cost of installing a new central AC unit and replace existing old furnace.This is in San Jose, CAHome is 1600 sq ft - 2 story Got quotes that range from 8.5k to 15kI guess the need is a 3.5 ton compressor and a 2 stage energy efficient furnace.

Of course, this week, the compressor died.

Had we thought about them prior, we may have made a different decision.When all of our baseboards are calling for heat at the same time, we are running at about 18KW.We could replace them with one compressor and 4 heads at about $7,300 (after rebates). 

The HVAC company they sent said the compressor was bad and not worth changing.

Plus the extra strain it puts on the compressor which is the most expensive component to replace.Dave

And each unit has central A/C, each with its own separate compressor thing (I'm obviously not an HVAC expert) outside behind the buildings!

You can pressure test the plumbing and hot water heating system using a generator and a small air compressor.

I would rather buy a compressor and brad gun than waste the money on a GC.

I'm still looking for a good (very granular and cost effective) GPS tracking for the HVAC compressors that I can covertly install when I get the property under contract and have active up until closing.

I had a flip a little larger than that, two stories that previously had radiators, where new ductwork was installed (both upstairs and down), returns were installed (again both upstairs and down), thermostat, AC electric disconnect installed, plus gas furnace and compressor - all that for around $7K.Regarding splitting profits - first you have to both agree on what will be considered allowed expenses!
