Furnace repair cost by part.
Typical San Fernando repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In San Fernando, furnace repair costs reflect the age of local homes—most were built around 1957, so systems are often older and may need more frequent service. Typical repair prices include flame sensor replacement ($70–$225), igniter ($125–$375), blower motor ($350–$1,300), control board ($250–$700), and heat exchanger ($1,300–$3,000+), plus a diagnostic fee of $65–$175. California requires a mechanical permit for most furnace repairs involving gas or electrical work, and Title 24 mandates Manual J load calculations and duct leakage testing for system replacements. With a mild Mediterranean climate and moderate cooling demand, many homeowners consider heat pumps for efficiency, though most homes still use gas heating. Federal 25C tax credits (up to $2,000 for heat pumps, $600 for high-efficiency AC) are available nationwide, helping offset upgrade costs.

- 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

Furnace Repair in San Fernando, explained.
What affects furnace repair costs in San Fernando?
The age of your system—often 20+ years in older homes—can increase labor time and part costs. Accessibility matters: furnaces in tight attics or crawl spaces may add to the diagnostic fee. Local permit fees and compliance with California's Title 24 (including HERS duct testing) add $200–$500 to a replacement job. The type of repair (simple sensor vs. major heat exchanger) and whether you choose a heat pump (eligible for federal credits) also shift the final price.
Common furnace repairs in San Fernando
Flame sensor failure
A dirty or faulty flame sensor is a frequent issue in older furnaces, causing the system to shut off after a few minutes. Replacement typically costs $70–$225.
Igniter problems
The igniter can crack or wear out over time, preventing the furnace from lighting. Repair runs $125–$375, common in units over 10 years old.
Blower motor issues
A failing blower motor reduces airflow and efficiency. In San Fernando's mild climate, this often goes unnoticed until the system stops heating. Replacement costs $350–$1,300.
