CHICAGO - The Unitary Products Group of York – a Johnson Controls Company – is introducing the York® [mc]² MicroChannel MiniCube 13 SEER air conditioner. Available in 1 to 3 ton sizes, the unit is the smallest 13 SEER product in the industry, according to the company.

The new air conditioner uses an aluminum tube coil and micro channel technology to provide higher efficiency without a corresponding increase in coil surface area. This technology significantly reduces the size of the unit compared to traditional 13 SEER products, and uses far less refrigerant, the company says. As a result, when moving from 10 to 13 SEER efficiency, the unit's footprint remains 21-3/4 inches square. Its height varies from 22-1/2 inches to 30-3/4 inches, depending on the unit's capacity.

A polymer mesh and a coated steel coil guard protect the unit's coils from damage, while a high-pressure relief valve and a temperature sensor protect the compressor from undesirable operating conditions. Top discharge blows warm air up and away from the structure and surrounding landscape and minimizes operating sounds. A rigid top panel, cushioned compressor mounts, and rippled condenser coil fins further reduce the unit's operating sound level.
