Pull out your lawn chair, and stare at the digital manifold gauge for an hour while they do a pressure decay test, then pull a deep vacuum. I'm serious.
I wish I’d read this before my heat pump installation in Jan 2024. Waiting for a refrigerant leak repair as we speak. I’m pretty sure my contract mentioned a 500 micron vacuum. I will definitely keep my eye on this when the new line set goes in.
Yeah, 500 micron is standard but 350 and below is even better. Glad you found this useful! Definitely keep an eye on the leak testing & make sure someone hooks up a gauge to do it + holds for a while
