How long will a Goodman AC last? Goodman AC will last 15 to 20 years on average with proper installation and regular maintenance, similar to industry average for central air conditioners. Lifespan depends on installation quality per Manual J and Manual D, correct refrigerant charge, airflow, climate, and maintenance like filter changes every 1-3 months, annual coil cleaning, and keeping outdoor unit clear. Goodman units built in Texas since Daikin ownership have improved durability, using Copeland scroll compressors and all-aluminum coils in some models. Entry level 14 SEER2 models may last 12 to 15 years, mid range 16 SEER2 15 to 18 years, high efficiency variable speed 20 SEER2 models can last 18 to 20 years with good care. Harsh coastal or extreme heat climates may shorten life to 12 to 15 years. With neglected maintenance, life drops to 10 years. Goodman warranty 10-year parts, lifetime compressor on premium models, supports long life. So Goodman AC lasts about 15 to 20 years, same as Carrier or Trane when properly installed and maintained, though premium brands may have slightly longer average due to heavier build.
