Common questions
How much does a new HVAC system cost?
A full system replacement (AC plus furnace) typically runs $6,000–$15,000 depending on size, efficiency and region.
Should I repair or replace my AC?
If a repair costs more than about a third of replacing the unit, or it's over 12–15 years old, replacement is usually the better long-term choice.
