Did you have your summer AC maintenance done in Tempe, AZ? If not, you’re probably overdue for an AC tune-up. In Tempe, where the summer heat often hits higher than 100 degrees, your air conditioner works overtime. It needs more AC tune-ups than a unit that doesn’t work as hard. Think of it like the miles you put on a car versus the time between oil changes. If you’re putting a lot of miles on a vehicle, it needs oil changes more often, and the same is true when it comes to air conditioning maintenance.
