I would like to know the relative efficiency of a 5 HP single phase vs. a 3 phase induction motor. The application is an air conditioning compressor (hermetically sealed motor). The same question would apply to a quirrel cage fan motor 1 HP.

Pick out specific motors of interest and see for yourself:

Have you tried contacting high-volume consumer-grade OEMs for their take on the matter? Induction motors for hermetic refrigeration would be considered fairly specialized. In the US, try Tecumseh and Copeland.

1 horsepower, 1800rpm single phase motor. 72% efficient at full load.
busbar is right that none of the motors in this catalog are hermetic.
