The Largest Standard Residential Size

A 5-ton (60,000 BTU/h) air conditioner is at the top of the standard residential range and overlaps with light commercial applications. It's appropriate for homes above 3,200 square feet in WNC, large open floor plans, homes with excessive heat gain (poor insulation, expansive glass, high ceilings), and small commercial spaces like offices, retail shops, and restaurants.

5-Ton AC Costs in WNC (2026)

14 SEER2 single-stage: $6,500–$9,000. 16 SEER2 two-stage: $8,000–$11,000. 18+ SEER2 variable-speed: $11,000–$15,000+. At this size, the investment is significant, making equipment selection especially important. The energy savings from a higher-efficiency model are proportionally larger with a 5-ton system — it's worth spending the premium on at least a 16 SEER2 two-stage unit.

Critical Installation Considerations

A 5-ton system requires: adequate electrical service (50–60 amp dedicated circuit), properly sized ductwork (2,000 CFM airflow), a concrete pad rated for the heavier outdoor unit, and often a larger indoor coil and air handler. Many residential homes in Asheville weren't originally designed for 5-ton equipment, so upgrades to ductwork, electrical, and sometimes the furnace/air handler are common additions to the installation scope.

When Zoning Makes More Sense Than One Big System

For very large WNC homes, a single 5-ton system may not be the optimal solution. A zoned system with two smaller units (for example, a 3-ton for the main floor and a 2-ton for upstairs) often provides better comfort, more efficient operation, and the security of redundancy — if one unit fails, you still have partial heating and cooling. Quality Comfort evaluates your home's layout and recommends whether a single large system or a zoned approach is the better investment for your AC installation.
