For comparable cooling, your current central air conditioner would have to
be 15,000 BTU, and they don't make them that small. Your current unit is
probably 230 volts, and most 5,000 BTU window units are 115 volts. To match
the BTUs you have now, 115 volt units, it will cost you twice as much in
electricity.

Are you assuming that the averaged SEER of window shakers is going to be
half that of a central AC unit?

We live in a mobile home in the southwest.

The central A/C unit is about 10 years old.

When the unit needs replacement,
could I get comparable cooling by installing
3 X 5K window units throughout the house ?

It would certainly be a helluva lot cheaper.....

How about efficiency ??

Good plan? or not ......
