In Arizona, an air conditioning unit typically lasts 10 to 14 years. However, since homeowners use their air conditioners more than other areas of the country, this variety is slightly lower than the prevailing (15 to 20 years according to The Department of Energy).
In addition, an air conditioning system ensures a systematic air supply. When your air purifiers are dirty, less airflow enters the AC, making it even more challenging for your AC system to function correctly.
