Single Zone Mini-Splits
Single zone DIY mini splits heat and cool one room — bedrooms, garages, additions, and home offices from 450 to 900 sq ft. Every Zone Air® system here is true DIY: the R454B lineset comes pre-charged with quick-connect fittings, so installation needs no vacuum pump, no refrigerant handling, and no EPA certification.
Choose 115V models (9K and 12K BTU) to run on a standard household circuit, or 230V models (9K, 12K, and 18K BTU) for up to 24 SEER2 efficiency. All wall-mount units heat down to −13°F and include WiFi app control. Prices start at $1,899.99.
