It's 4 systems with 4 compressors and 10 inverters.

Small cottage, 598 sqft, getting it for $63,500 (was listed at $72,500) with seller replacing the whole A/C system (compressor, condenser, air handler, furnace, heat pump) and him paying all my closing cost.

The outside a.c. compressor has no where to fit in the backyard due to the basement steps and can't go on the side of the house because of the width of the property.

Old compressor has suspenders a felt or rubber grommet will damped the vibration.

About 1325 sq ft, 1 compressor, 4 heads. 

I have learned that a poor refrigerant charge can make compressors run much more often than they need to, substantially increasing electricity use.

You may have had discussions about living there, but I bet you didn't have discussions about air compressors, circular saws, and drywall demo. 

Capacitor was burnt out so the compressor and fan wouldnt start.

The contractor I used on my last project wanted $11,000 to install a new 3 ton heat pump (brand new system, new compressor, air handler, run duct, etc) in this house.  

In Las Vegas, the most expensive (typical) repair item is an air conditioner compressor, costs about $2,500.
