Frequently Asked Questions
How much does a mini-split system cost?
Mini-split costs depend on zones: Single-zone $3,000-$5,000. Dual-zone $5,000-$9,000. Three-zone $8,000-$12,000. Four-zone $10,000-$18,000. Whole-house multi-zone systems replacing central HVAC cost $15,000-$30,000.
Are mini-splits worth the investment?
Yes, mini-splits are worth it for: homes without ductwork, room additions, garage conversions, or zoning flexibility. They're 25-50% more efficient than window units and allow room-by-room temperature control. Payback through energy savings is 3-7 years.
How long do mini-splits last?
Quality mini-splits last 15-20+ years with proper maintenance. Premium brands (Mitsubishi, Daikin, Fujitsu) often have 12-year compressor warranties. Annual maintenance includes cleaning filters monthly and professional service yearly ($100-$200).
Can mini-splits heat in winter?
Yes, modern mini-splits are heat pumps that heat and cool efficiently down to -15°F (some to -25°F). They're 2-3x more efficient than electric resistance heat. In very cold climates, they work best as primary heat with backup for extreme cold.
