The Honest Answer: Sometimes Central AC is Still Right

This comparison isn't designed to sell mini-splits. It's designed to help you make the right choice for your Dallas home.

Central AC Replacement: $4,000–$8,000 (assumes existing ductwork). New ductwork adds $8,000–$15,000.

Mitsubishi Mini-Split: Single-zone $3,500–$5,500. Two-zone $6,000–$8,500. Three-zone $8,000–$12,000.

Central AC: 14–16 SEER2. Mitsubishi M-Series: 20–33 SEER2. Annual savings: ~$450 per year. Over 15 years: $6,750 in operating savings.

Adding ductwork to a 1920–1960s home costs $8,000–$15,000. A Mitsubishi mini-split requires one 3-inch hole through an exterior wall.

Central AC ductwork in unconditioned attics loses 20–30% of capacity. Mini-splits have zero attic heat loss.

Central AC: one thermostat for the whole house. Mitsubishi MXZ: each zone has independent control.

Mitsubishi: 19–46 dB(A). Central AC blower: 50–70 dB(A).

Large homes with excellent existing ductwork. Budget is the primary constraint. New construction.

Pre-ductwork older homes. Long-term operating cost matters. Attic heat loss is significant. Room-by-room control. Quiet operation.
