AC repair cost by part.
Typical Pasadena repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
AC repair in Pasadena, California, typically costs between $175 and $3,400 depending on the component, plus a $90–$250 diagnostic fee. With a median home age of 66 years, many systems are older and may require more extensive repairs. Pasadena's mild Mediterranean climate means moderate cooling demand, but hot-dry inland summers can still push older units to fail. California's Title 24 mandates HERS-verified duct leakage testing and Manual J load calculations for most AC changeouts, which can add to repair costs if a full replacement is needed. Heat pumps are recommended for new installations to qualify for the federal 25C tax credit (30%, up to $2,000).

What Pasadena code requires
Installing or replacing an HVAC system in Pasadena follows California rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southwest, <45k BTU)
Federal Southwest-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRequired (Manual J)
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
CA Title 24 requires HERS-verified duct leakage testing and Manual J sizing on most AC/furnace changeouts
