@hvacknowitall: Understanding new nomenclatures... We discuss the first 3 letters on newer Copeland scroll compressors. Y - A2L H- Heat Pump (this compressor is for a water cooled heat pump application) V - Variable Speed Also remember, R454b is a blended refrigerant with a negligible glide. It can be topped up to an existing system without removing the entire charge after a leak is repaired. #hvac #hvacr #heatpump #a2lrefrigerant #copelandcompressor
Umm, not true. R410A does not glide easy but R454B glides real easy. We test it all time after a recovery's and have to correct it with R1234yf or R32. I have to correct it 3-4 times as much as R410A.

Funny that the Rheem compressor from last year with the 410a are the same units for 454b

If you lost more than 25 percent of your charge on 410a you need to pull the charge and reset the charge that is why you have to charge as a liquid is because it does infact separate
