The major advantage that evaporative coolers have over traditional AC units is portability. Window and wall mounted air conditioner units are limited only to a single room. By contrast, evaporative coolers can be easily rolled from room to another along caster wheels. Another advantage of evaporative cooling technology is that it only uses water and does not produce any other by products such as gases and heat. Evaporative coolers are available in various sizes designed to cool off small spaces to an entire level of a home. It is recommended that an air filter such as HEPA be installed into an evaporative cooler.

Yes, many homes have "swamp coolers" on the roof and for the reason given. However, many homes built in the 80s and 90s also had the AC unit/heat pump on their roofs. I have two units on my two story homes roof.
The easiest way to cool an older home that heated with radiators, is to use window AC units. Storing these window AC units during the winter can be a lot of work. What is are some suggestions for properly storing window AC units during the winter?
No - actually, it'll have a more opposite effect. The superheat will be low, system pressure will be high, and the result will be insufficient cooling.

Check the superheat in the system.
If AC = 10 units and D is the midpoint of AC then AD = AC/2 = 5 units!
RV AC units are interchangeable. This is true as long as you replace the whole unit and not just one part.
