Single-row Spine Fin coil - Constructed from thousands of tiny spines, it provides more surface area, adding greater heat transfer capabilities and more efficiency over time.

Single-speed fan motor - Conserves energy and operates quietly, so noise levels are kept to a minimum.

Steel louvered panels - Designed to protect the coil from leaves, hail and other potentially damaging elements.

Aluminized steel heat exchanger is crimped, not welded, to prevent cracks from heat stress. Stamped serpentine channel offers greatest efficiency in less space. Backed by our 20-year, non-prorated, limited warranty.
