Air Dominion Mini Split Line Set Installation Kit
Reviewed pricing, lead time, freight, and final configuration are confirmed during quote review before order release.
Air Dominion Mini Split Line Set Installation Kit bundles the three run-length items every mini split install consumes together: the insulated flared line set, control wire cut to the same length, and a 20 ft condensate drain line. Pick the line size that matches the system's labeled connections and the length that matches the route - one kit replaces three separate line items on the quote. This Air Dominion quoting record is presented as a reviewed accessory configuration, with final configuration confirmed during quote review before release.

Frequently Asked Questions
How do I pick the right kit for my system?
Match line size to capacity class - 1/4 x 3/8 for Air Dominion 9K and 12K, 1/4 x 1/2 for 18K, and 3/8 x 5/8 for 24K standard chassis - then pick the length that covers the routed run. Sizes are confirmed against the unit label during quote review.
What is in the kit besides the line set?
Control wire cut to the same length as the line set and a 20 ft condensate drain line - the two other run-length consumables of a standard install.
Does it include the disconnect and whip?
No - electrical-side items are in the Condenser Electrical Accessory Kit or the Single-Zone Complete Installation Kit.
