You can get a system with one compressor and multiple "heads".

Also, that figure would be for the compressor and fan combined, need to estimate a "duty" cycle for the compressor which utilizes most of the wattage, but only when it is operating.

The report stated:Plumbing tested with air compressor and system did not hold 35 psi for at least 15 minutes.I have no idea what this could indicate...does anyone have any experience with this?

There is definitely no point in trying to replace just compressor or just air handler Etc....

The sale typically makes no difference.....the condenser lines run up the exterior wall next to the compressors, then through the attic.  

because as a realtor I’ve seen places where AC compressors used to be.

The pressure test they do is via a compressor attached to (generally) a washing machine hook up.

Some are aerated, meaning they have an air compressor pumping air into the system 100% of the time.

Another cabin had placed the hot tub in a remote area under the deck, near the central a/c compressors, downstairs and away from the main hub of the home.

(I have had tenants turn the AC off when they move out or the heat in winter)- We require they have someone check on the property if they leave it for more than 5 days (This is to make sure there are no water leaks or HVAC issues that lead to problems while they are gone)- No businesses can be run from the property (to prevent day care, laundry services, gambling, drugs or who knows what)- We specify yard care includes week spraying and cleaning up sticks less than 1" in diameter (otherwise tenants think yard care is mowing only)- We state that tenants utilities can be used for routine maintenance or repairs (I once had a tenant complain the roofers were using his power for their compressors)- We have a whole section on mold stating that mold is naturally occurring and results from excess moisture.
