Key Price Drivers for Air Conditioner Repair

  • What failed: A capacitor is under $300 installed. A compressor or an evaporator coil can approach the cost of a new system, which is when the repair-versus-replace question becomes real.
  • Refrigerant type: R-22 is no longer produced and costs several times more than current refrigerants. A leak on an R-22 system usually favors replacement.
  • Diagnostic fee: Most companies charge $75 to $200 to diagnose, often credited toward the repair if you proceed.
  • Timing of the call: Emergency, after-hours and weekend calls during a heat wave carry premiums of 50 to 100%.
  • Warranty status: Most equipment carries a 10-year parts warranty if it was registered. Labor is usually not covered past the first year, but the part itself may be free.
