Air Conditioning Restored After Outage at Phoenix Sky Harbor Terminal 4

An air-conditioning outage affected Terminal 4 at Phoenix Sky Harbor International Airport on Oct. 23 after a maintenance issue caused higher-than-normal temperatures in the terminal. Airport crews brought in temporary cooling units and large fans while working to restore the system; travelers reported it felt warm but many remained in jackets and flights were not impacted. The outage affected passenger comfort but did not disrupt flight operations, and carriers such as American and Southwest operate out of the terminal. Repairs were completed and the terminal’s air conditioning was reported back online around 2:30 p.m. Sky Harbor previously experienced a similar AC disruption in July during planned maintenance that ran slightly over schedule.
