Frequently Asked Questions
How much does HVAC installation cost? +
HVAC installation costs $5,000–$12,000 for a central air system. A furnace alone runs $2,500–$6,000, a central AC unit $3,500–$7,500, and a heat pump $4,000–$8,000 installed.
How often should HVAC systems be replaced? +
Air conditioners and heat pumps last 15–20 years, furnaces 20–30 years, and ductwork 20–25 years. If repair costs exceed 50% of replacement cost, it's generally time to replace.
