Yeah Asshole, understand there's a difference in the two following statements...
"R410 refrigerant is more efficient than R22"
"An R410 14 SEER unit is more efficient than a R22 14 SEER unit"
Now look at the thread title, it says "R-22 vers R410". It says nothing about complete systems!
If you had a brain, you wouldn't be agruing about this.
Also, if you were informed, you would already know what brand Noon-Air sells... hint, it's not a Carrier product. Now crawl back in your hole and shut the hell up.
