What to know before buying

The manufacturer says the system ships in two separate boxes that may arrive at different times. Check electrical compatibility with the listed 230 volts and plan for split-system installation.

Listing details to confirm

The title and feature text describe both heating and cooling, while the details field lists the operating mode as Cooling. The listing also presents 19SEER2 in the title but 19 as the SEER field, and describes an inverter compressor alongside an unclear compressor type of rotary_scroll. Confirm the exact rating, heating capability, compressor specification, and selected-unit configuration before buying. The stated 750-square-foot coverage is a manufacturer claim, not a room-sizing guarantee.
