Summerlin homes run large. 3,000–5,000 sq ft is common in the newer villages. That means most systems are 4- or 5-ton units, and sizing mistakes get expensive fast. An oversized system short-cycles and never properly dehumidifies. An undersized one runs constantly and still can’t keep up past 3PM in July.
The west-facing elevations in communities like Red Rock Country Club and The Ridges deal with serious afternoon heat gain. That’s not something a generic replacement fixes. It’s a load calculation problem. We do Manual J before we spec any replacement, and we explain what it means.
High-efficiency systems and correct sizing mean lower operating costs over the lifetime of the equipment, which matters more in Summerlin, where systems run harder and longer than anywhere else in the valley.
