AC repair cost by part.
Typical Chelsea repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Chelsea, MA, has a median home age of 88 years, so AC repair is common. Local diagnostic fees run $70–$175, with typical repairs like capacitor/contactor replacement costing $150–$375 and refrigerant recharge $225–$700+. Massachusetts requires a mechanical permit for most AC repairs, and homeowners should expect a load calculation for proper sizing in Climate Zone 5.
