AC replacement cost
It depends on your home, the system and its efficiency. Your free estimate shows the price before you decide.
Is it time to replace?
Well-maintained central air conditioners last about 10 to 15 years. ENERGY STAR suggests budgeting to replace a unit more than 10 years old.
Higher SEER2, lower bills
A new air conditioner, especially a variable-speed model, uses less electricity than an older unit that runs longer.
If your furnace is also near the end of its life, replacing the AC and the heating at the same time is generally more cost-effective on installation.
