The condenser unit being just delivered and being old is a red flag... not many rentals in that class have garbage disposals I would remove that.

Once, I had a tenant  install a window AC improperly so that the condensation dripped into the window sill and inside the house. 

But I'm very busy building my business to boost my profits and don't have the time to wade through everything.It makes more fiscal sense to spend the money to get the condensed version, then it does to take those countless hours away from work to learn bits and pieces here and there.

Although I am going with this guy for this job, I am always looking for more properties and can work with newer people if I can save some costs.I got the below pricing for a completely new system including new ductwork2 ton 14 seer AC Unit Franklin (by amana)Gas Furnace 80% 40.000 buts to 60.Evaporator coil concrete slabrefrigerant copper lines and insulation low voltage wiring for thermostat and condenser. 5 to 7 Supply air ducts boots and grill.2 return intakes grills under the unitDig. thermostat Suppl plenum Miscellaneous material to complete job10 years warranty equipment 1 year labor warranty.

It did not include hookup of utilities or AC condenser.

It had an outside condenser that fed two interior wall units.

Most of the 220 I see is for things like HVAC condensers and electric ovens and those are usually pulling 30 amps or more, which is going to account for more power usage than on a 15 or 20 amp 110.

So much is upgraded from the original (electrical, roof, a/c condenser).

Would lifting my air condenser onto a platform on any property reduce the flood insurance?

High humidity and condensation can cause mold.
