Frequently Asked Questions

How much does HVAC replacement cost?

HVAC replacement costs range from $5,000-15,000+ depending on system type, size, and efficiency. A standard AC/furnace combo runs $6,000-12,000, heat pumps $5,000-14,000, and ductless mini-splits $3,000-8,000 per zone.

How long do HVAC systems last?

Central air conditioners last 15-20 years, furnaces 15-25 years, and heat pumps 10-15 years. Regular maintenance extends lifespan. Systems over 15 years old with frequent repairs should be evaluated for replacement.

What size HVAC do I need?

HVAC sizing depends on square footage, climate zone, insulation, and windows. A rough estimate is 1 ton (12,000 BTU) per 400-600 sq ft. Proper sizing requires a Manual J calculation by a professional.
