How much does it cost to install central air?

When should I replace my HVAC system?
Replace your HVAC system when it's 15+ years old, repair costs exceed 50% of replacement cost, or efficiency has dropped noticeably. Newer high-SEER systems in Seattle can cut cooling bills 20-40%, often paying back the upgrade within 7-10 years.
How often should HVAC be serviced?
