There is no universally standardized AC tune-up cost. Many contractors offer many different prices, as well as offering a different range of services. Some tune-ups are super standard, offering some baseline cleaning and inspections. Others are fully comprehensive, offering calibrations, component lubrication and checks, filter changes, and much more. Generally speaking, your fairly standard no-frills tune-up is going to run around roughly $100 for labor, travel time, and the service itself.
