Replacement timing
How Long Does an Air Conditioner Last?
Many central air conditioners operate for 12 to 18 years, but maintenance, installation quality, usage, climate, and coastal exposure affect service life.
Age is one signal
An older air conditioner is not automatically finished, but repair risk and efficiency gaps often rise over time.
Watch performance
Long run times, weak airflow, rising electric bills, humidity, unusual noise, and repeated repairs can signal a larger problem.
Plan before failure
Shopping before a heat-wave emergency gives you more time to compare equipment, pricing, and financing.
