Absolutely. And the HVAC company will do it. I was just curious to understand the process. I actually found the service manual for the Amana ASX16, and it has no mention of this charging requirement.

I'll trust the company knows what he's doing. He's been doing it for years. I'm only interested in knowing because he said he doesn't do a lot of 2 stage residential units.

Looks right to me. Mine is working great. Although, you may not need Red to the condenser if no heat...The wiring manual would tell you for sure.

Although my condenser does have a red wire, I didn't hook it up per what Goodman/Amana told me, and what the wiring diagrams showed.
