Mini Split Air Conditioners

A mini split is a ductless heating and cooling system: a compact outdoor condenser connects to one or more indoor air handlers through a small refrigerant line set, so you can condition the rooms you actually use without installing ductwork. Because they are inverter-driven heat pumps, mini splits deliver high-efficiency air conditioning in summer and reliable heat in winter, controlled room by room.

This collection covers our standard mini split systems from brands including MRCOOL, Daikin, Senville, Pioneer, Mitsubishi, GREE, and TOSOT. Single-zone systems pair one condenser with one indoor unit — ideal for a garage, addition, bedroom, or shop. Multi-zone systems run two or more indoor units off a single condenser for whole-home comfort. Standard systems use flared line sets and should be installed by an HVAC technician; if you would rather do it yourself, check out the MRCOOL DIY line with pre-charged quick-connect line sets.

Start with capacity: roughly 9,000 BTU covers 250 to 400 sq ft, 12,000 BTU covers 400 to 550, 18,000 BTU covers 600 to 800, and 24,000 BTU and up handles large or open spaces. Our sizing guide and support team can help you dial in the right fit.
