AC maintenance & tune-up cost.
Typical Johnston pricing for seasonal service, adjusted for local labor. Plans that bundle two visits a year lower the per-visit cost.
In Johnston, Iowa, a standard AC tune-up typically costs between $70 and $175 for a single visit, with coil cleaning adding $95 to $375. Many homeowners opt for an annual maintenance plan covering two visits for $150 to $325. Johnston's median home was built in 2003, meaning most systems are about 23 years old and may need extra attention during a tune-up. Iowa requires a mechanical permit for AC work, and the state's cold climate means furnaces or heat pumps with backup are common. The federal 25C tax credit offers up to $600 for high-efficiency central AC, but tune-up costs themselves are not eligible.

With R-410A being phased out, older systems may develop leaks; checking refrigerant levels is a key part of a tune-up.
