Efficiency
Efficiency is a factor of how much power it takes to do a useful amount of work. There are two efficiency ratings for cooling: Seasonal Energy Efficiency Ratio (SEER) and Energy Efficiency Ratio (EER), and two for heating: Annual Fuel Utilization Efficiency (AFUE) and Heating Seasonal Performance Factor (HSPF).
Comfort
Comfort Rating as used is a combined measure of motor or compressor performance, sound and controllability. For example, variable speed technology typically provides more precise and more quiet operation, and therefore gets a high Comfort Rating.
