Furnace repair cost by part.
Typical Fairfax Station repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Fairfax Station, Virginia, furnace repair costs reflect the area's high homeownership rate (93.1%) and older median home age (44 years). Typical repairs include flame sensor replacement ($75–$225), igniter replacement ($150–$425), or blower motor repairs ($375–$1,400). A diagnostic fee of $70–$175 applies. Virginia's Uniform Statewide Building Code requires mechanical permits and inspections for furnace changeouts, though repairs may not always require a permit. The mixed-humid climate means furnaces are used heavily in winter, making timely repairs important. Many homeowners consider heat pumps for replacement, as they qualify for federal 25C tax credits (30%, up to $2,000).

- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southeast)

- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.

- Good to know—
Virginia uses the statewide Uniform Statewide Building Code (USBC/IECC); local mechanical permits and inspections are required for AC/heat pump/furnace changeouts, and Manual J/S sizing is recommended practice though not strictly enforced.
