How old should my HVAC system be before replacing?

Furnaces and air conditioners typically last 15 to 20 years with proper maintenance. If your system is over 15 years old, needs frequent repairs, or your energy bills are rising, it may be time to replace. New systems are significantly more efficient and can lower your utility bills by 20 to 40 percent.

Why It Matters

Waiting too long to replace an aging HVAC system risks a mid-summer or mid-winter breakdown and higher energy costs.
