Can I really install this myself?

MRCOOL designed it for DIY: the line sets come pre-charged with Quick Connect fittings, so you don't need a vacuum pump or refrigerant gauges. You still need basic electrical work and ceiling openings for the cassettes.

How much space does it cover?

It is rated for up to about 1,200 sq ft across two zones. Each 18K cassette handles one room, so coverage depends on how the two rooms are sized and insulated.

Does it work in cold weather?

Yes. It is a heat pump rated to heat down to -13°F, with a 9.5 HSPF2-4 rating.

What comes in the box?

The pre-charged condenser, two 18K ceiling cassettes with mounting plates and wall templates, a remote with batteries, washable filters, drain hose and extension, communication wire, wall sleeves, UV-resistant wrap and the pre-charged line sets.

How does it compare with a wall-mounted multi-zone?

You get the same DIY Quick Connect setup and efficiency, but the ceiling cassettes free up wall space and spread air from above. The trade-off is more ceiling work at install and drain routing.

What warranty do I get?

A 7-year compressor warranty and a 5-year parts warranty. MRCOOL also offers an optional lifetime compressor warranty.
