HVAC Replacement Cost
Replacing your entire HVAC system is a major investment most homeowners face every 15-20 years. Typical cost: $5,000-$12,000, with premium systems exceeding $15,000.
What's Included
Complete replacement includes outdoor condenser, indoor air handler or furnace, thermostat, and sometimes ductwork modifications. Labor is 30-40% of total cost.
Cost Factors
System size (tons), SEER/AFUE ratings, brand, and home accessibility all impact pricing.
Signs You Need Replacement
Frequent repairs, uneven temperatures, rising energy bills, and age over 15 years are clear indicators.
Choosing Right
Heat pumps offer heating and cooling in one unit for moderate climates. Traditional split systems work best in areas with extreme winters.
Related Questions
How often should HVAC be replaced?
Every 15-20 years. Regular maintenance extends lifespan but efficiency drops after 15 years.
Can I replace just the AC or furnace?
Yes, but replacing both ensures components are matched for optimal efficiency.
What SEER rating should I choose?
Minimum is 14-15 by region. 16-18 SEER offers a good balance of efficiency and cost.
