I think there's probly hope for him, judging from the quality of information he has given in the past.
Otherwise, I wouldn't have even bothered.
How many BTU A/C ?

The capital costs of two 110VAC units may be less for a given number of BTUs but the real concern is going to be operating costs. One big
24000 BTU unit is almost always going to be more efficient than two 12000 BTU units when you consider the cost of converting electrical watts to cooling capacity. (You will have one more compressor...one more blower, etc.)Beachcomber
This is Turtle.
If you want a Guess here . well Here is where you can go to get a good guess.

Nonsense. While a larger unit is inherently more efficient, just as
220VAC is inherently more efficient than 110VAC for motors, in reality there's no difference, and small units are commonly available with efficiencies of EER 10 (roughly like SEER 12). Also on a milder day, operating just 1 of the smaller units may be more efficient since it'll probably remove more humidity by running continuously.
I picked up a 11,800 btu like-new for $20.
