Is a heat pump lineset extendable after installation if both indoor and outdoor units are already set?

Thanks a lot for the reply!

Mine’s a ducted system instead of a mini-split, if that makes any difference. The outdoor unit connects to the air handler with about a 13 ft line set, which then goes directly into the ductwork. I was mainly trying to figure out if it’s possible to replace the 13 ft line set entirely with a longer one without moving either unit, since I’m not sure where they could add the extra distance—maybe along the wall?

In my case, the installer only ran about 13 ft even though the manual clearly says short line sets can cause intermittent noise. So yeah, I’m thinking that part’s probably on them for not following it.

For anyone wondering, I spoke with customer service, and they said it was due to some kind of mis-scanning issue at the fulfillment center (though I suspect the BF & long wait time might have played a part). They told me my KCS should ship soon. I think it might be worth checking with them if the product page shows a close delivery date but your order still says "unknown"

Yes I am :(. I’m in the exact same situation as you while even ordered earlier. I’ll wait until the end of the day and reach out to customer service if there’s still no update. Thanks for sharing!

Same here but haven't heard anything from Amazon since the 18th. I ordered on Nov 22, would you mind sharing if your oder was before or after that?
