Repair usually makes sense when the system is newer, the failure is isolated, and the cost is modest. Replacement becomes more realistic when the unit is older, uses obsolete refrigerant, has repeated compressor or coil issues, or the repair cost is close to the value of a more efficient system.
Common signs your AC needs repair include: not cooling effectively, unusual noises (grinding, squealing, banging), strange odors, frequent cycling on/off, increased energy bills, ice on the coils, or water leaks. If you notice any of these, schedule a diagnostic appointment.
AC repair costs vary by issue: diagnostic fees run $75-150, refrigerant recharge $150-400, capacitor replacement $150-300, fan motor $200-500, compressor repair $500-1500. We provide upfront pricing before work begins.
