Common HVAC repairs in Pasadena

  • Heat pump not cooling on humid summer days — low refrigerant, frozen coil, or failing capacitor.
  • Furnace short-cycling in winter — dirty flame sensor, oversized equipment, or thermostat miscalibration.
  • AC blowing warm air — condenser-fan failure, tripped high-pressure switch, or refrigerant leak.
  • Uneven temperatures room-to-room — failing zone damper, duct leakage, or blower-motor issue.
  • Loud banging, squealing, or grinding from the air handler — bearings, belt, or blower-wheel imbalance.
  • Thermostat shows the right setpoint but the system won't start — control board, transformer, or wiring fault.
  • Water pooling at the air handler — clogged condensate drain or cracked pan.
  • Frozen evaporator coil that keeps icing over — airflow restriction or low charge.

Repair vs replace: quick decision tree

  • Age > 15 years — Expect diminishing returns on any single repair. Start pricing replacement in parallel, especially if a second failure in the last 24 months.
  • Repair cost > 50% of replacement — A $2,500 repair on an $8,000 system rarely pencils. Run the 5-year math: repair cost + likely follow-on failures vs new-system financing.
  • Uses obsolete refrigerant (R-22) — R-22 is phased out; refills are both expensive and short-lived. Replacement is almost always the right call.
  • Failed a major component (compressor, heat exchanger) — These are “the system”. A compressor on a 12-year-old condenser is a replacement signal, not a repair.

Typical repair cost range

Pasadena repair range$948 – $9,653per repair visit

Derived from local HVAC benchmarks in Pasadena. Most repair tickets fall well below full-system pricing — expect simple swaps (capacitor, ignitor, thermostat) at the low end and major component replacements (blower motor, control board, compressor) at the high end.

Frequently Asked Questions

  • How long does a typical HVAC repair take in Pasadena?

    Most diagnoses take 30–60 minutes on site. Small repairs (capacitor swap, thermostat, ignitor) finish the same visit. Parts-on-order repairs can push the job 1–5 business days depending on supplier stock.

  • Do repairs come with a warranty?

    Labor warranties of 30–90 days are common; parts usually carry the manufacturer's warranty (1–10 years). Always get the warranty terms in writing on the invoice before the tech leaves.

  • How do I avoid common repair scams?

    Red flags: no written estimate before work starts, refrigerant refill with no leak search, blanket recommendation to replace without an inspection, or very high "after-hours" pricing on a non-emergency call. Two written quotes for any repair over $600 is the fastest sanity check.

  • When should I replace instead of repair?

    When the repair estimate exceeds 50% of a new system, or the unit is past 15 years, or it uses obsolete refrigerant (R-22), replacement usually wins the 5-year math. Otherwise repair is almost always the better call.
