AC repair cost by part.
Typical Ferguson repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
AC repair in Ferguson, Missouri, typically costs between $125 and $2,100+, depending on the part and labor. With a median home age of about 70 years, many systems are older and may need more frequent repairs. Local diagnostic fees range from $60 to $150. Missouri has no statewide mechanical code, so Ferguson sets its own permit and inspection rules—always check with the city before work begins. Most homes use a gas furnace with central AC, and the mixed-humid climate means moderate cooling demand. For 2025, new systems must meet 13.4 SEER2 minimum and use R-454B or R-32 refrigerant, as R-410A is being phased out.
