The Spartan series Is the next in the line of Willis single zone systems. It features a swing compressor design to reduce friction resulting in a smoother and quieter operation with less vibration and longer durability. Also available in 9, 12, 18, and 24, thousand BTU capacities, the Spartan series offers all the advanced features found in the Godwin series, while providing low ambient cooling (up to 5% Fahrenheit). Due to its higher SEER rating of 16 the Spartan series is Energy Star certified thereby insuring great performance while consuming less energy,
