How much does a new HVAC system — planning ranges for 2026?

Central AC replacement costs $3,500-$8,000 installed. Furnace costs $2,500-$7,500. Heat pump runs $4,000-$10,000. Mini-split systems cost $2,000-$5,000 per zone. All costs include equipment and labor.

How long does an HVAC system last?

Central AC units last about 15 years. Furnaces last about 20 years. Regular maintenance (annual tune-ups, filter changes every 1-3 months) extends lifespan. R-22 refrigerant systems should be replaced regardless of age since the refrigerant is phased out.

Duct cleaning	$300 – $600
Duct sealing	$300 – $1,000
Smart thermostat	$75 – $300

Warning signs your HVAC is failing

R-22 refrigerant system (phased out, no longer available), frequent repairs costing $300+ per year, uneven temperatures between rooms, unusually loud operation, and energy bills climbing despite normal usage. Two or more of these means replacement is more cost-effective than continuing to repair.

Efficiency savings

New systems are 30-50% more efficient than units from 15+ years ago. Average savings: $500-$1,200 per year on energy. A high-efficiency furnace (96%+ AFUE) saves $200-$500 per year in fuel costs vs an 80% unit.

Leaky ductwork wastes 20-30% of heating and cooling energy. Before replacing your HVAC unit, have ductwork tested. A $300-$1,000 duct sealing job might solve comfort issues without a system replacement.

A yellow burner flame on your furnace (should be blue) or a cracked heat exchanger are carbon monoxide risks. These are not repair situations — replace immediately.
