Weird situation here. Hoping someone can help. Im trying to make a glycol chiller for beer making. I have a newish portable ac that I tore apart for the chilling component. I need to bypass all the circuit board electronics. I want to send the electric from the plug, to the capacitor, to the condenser and fan. is this possible? And if so, can anyone help me with the many different wires and relays? I figure I don’t need the relays. I want to use a temperature controller outlet to turn on and off based on glycol temp, but there are three relays. I just don’t understand the wiring enough to do this. any help would be greatly appreciated!!

The HVAC in my home is 19 years old and running well but I'm starting to plan for it's replacement. I'd like to use the same contractor I do for my rental houses and they sell Goodman and Amana. As a first pass I'm comparing the 4 ton Goodman GSXC18 (18 seer, two stage) and the 4 ton Amana AVXC20 (20 seer, variable speed). A primary goal is a quiet condenser since it's located close to our screened porch. Does anyone have opinions or advice about which way to go? I only have experience with more primitive single stage units so I feel slightly better about two stage though variable sounds sexy.
