A new AC system costs $5,500–$8,000 installed. Modern systems (SEER 16) are 20–30% more efficient than 12-year-old systems (SEER 10–12).
Example: Your current system costs $180/month to cool in July. A new SEER 16 system cuts that to $135/month — a $45 monthly savings. Over 15 years, that is $8,100 in energy savings.
Financing changes the math. Many homeowners finance AC replacement over 10 years at 6–7% interest. Ask about rebate programs — many utilities offer $500–$1,500 rebates for high-efficiency systems.
Modern systems do more than cool. New units offer variable-speed compressors, smart thermostats, better dehumidification, and quieter operation. Ask about
