The following ductless heat pump equipment types can be covered by the PUD incentive:
Mini-Split
Systems that have a single outdoor compressor and one or more indoor heads. Multi-head (or multi-zone) systems are considered mini-splits as long as they are served by a single outdoor compressor.
Non-ducted
An indoor unit which directly heats or cools air within the conditioned space without attached distribution ductwork. The following types of indoor units are considered non-ducted: Wall-mounted, floor-mounted, ceiling suspended, and ceiling cassette (standard and compact) .
Ducted
An indoor unit which heats or cools air within the conditioned space through the use of distribution ductwork. Though ducted indoor units can be ceiling-suspended, they are typically ceiling-concealed and consist of short duct runs serving multiple zones from the single indoor unit.
Mixed
A combination of ducted and non-ducted indoor units served by a single outdoor section.
