In Kirkwood, Missouri, where the median home was built in 1963, regular AC maintenance is key to keeping older systems running efficiently. With a mixed-humid climate and moderate cooling demand, a typical tune-up costs between $75 and $200, while coil cleaning runs $100 to $400. Many homeowners opt for an annual maintenance plan (two visits) for $150 to $350.

What Affects AC Tune-Up Costs in Kirkwood

Faulty Capacitors
Capacitors wear out over time, causing the compressor or fan to fail.
