What is the range of a cost to move an AC unit?

One is about 5 ft away (or really 3 ft) - lateral or almost adjacent move.

The second is about 4 ft away but going into the attic - so it is moving it above.

What does it cost for material to re-duck a home? Cost of labor?

My understanding is that it is 110 linear sq ft per 1000 sq feet of home. Is this correct?

Lets say you have 4000 sq ft (make math easy) then you'd need about 37 linear sq ft, right?

Do you charge for ducks by linear square feet (e.g. above 37 linear sq ft) or by the entire sq ft of the home, in this example 4000 sq feet?

We received a quote for moving moving two units and 3000 sq ft at $26,000.

That is $7 per sq ft of the house and about $97 per linear sq ft of ducks. It is material and installation.

Is this reasonable?
