If I had to guess its probably less than 2 minutes and you could carry on a conversation at 100% with a 75 degree ambient load.
Worked on the variable speed screws since 2007, only replaced two compressors, out of 30 or so machines out there in my area. The YVAA and YVWA are the newest and are a flooded evaporator as compared to the YCAV and YCIV which where DX evaporators. As far as the 0-full load in 60, never really notice, but do't think so because things need to adjust and settle out or they may fault on low pressure. However the YVAA/YVWA are new and with that maybe. They have been good machines.
