HVAC Costs in 2026: Repair, Replacement & Installation Prices

HVAC System Costs in 2026

A new HVAC system costs $5,000-$12,000 on average, while repairs typically run $150-$1,500. Here's a complete pricing breakdown.

HVAC Repairs

• AC refrigerant recharge: $150 – $400
• Blower motor replacement: $300 – $600
• Compressor replacement: $800 – $2,800
• Thermostat replacement: $150 – $400
• Duct repair/sealing: $300 – $1,000
• Capacitor replacement: $150 – $300

New System Installation

• Central AC unit: $3,500 – $7,500
• Furnace: $2,500 – $6,000
• Heat pump: $4,000 – $8,000
• Mini-split (ductless): $2,000 – $5,000 per zone
• Complete HVAC system: $5,000 – $12,000

Sizing Matters

HVAC systems are sized in tons (1 ton = 12,000 BTU). Undersized systems run constantly; oversized systems cycle too frequently. A proper load calculation by a licensed tech ensures the right size. For reference: 1,000 sq ft typically needs 1.5-2 tons in moderate climates.

Energy Efficiency Ratings

Higher SEER ratings mean lower operating costs. Minimum is 14 SEER; 16-20+ SEER units cost more upfront but save $200-$600/year on electricity. The federal government offers tax credits up to $2,000 for qualifying high-efficiency systems.

When to Replace vs. Repair

The 50% rule: if repair costs exceed 50% of a new system AND your unit is 10+ years old, replacement is usually the better investment. New systems are 30-50% more efficient than 15-year-old units.
