The ETL-listed Utopian Systems Split Air Conditioner 33,000 BTU keeps indoor gardens cool and air quality high, and an included heat pump doubles its utility. The split design incorporates an indoor and an outdoor unit, which can be more cost-effective and easier to maintain than central air while being less noisy and obtrusive than a window unit. Features including quick-connect refrigerant pipes, auto-restart, a 24-hour programmable timer, three fan speeds and remote-controlled operation ensure optimal performance. A carbon air filter helps to eliminate harsh odors and deactivate harmful chemical gases. Low-ambient operation continues to cool indoors even when outside temperatures fall below 55 degrees Fahrenheit. This unit includes a one-year warranty.
