Furnace repair cost by part.
Typical Randallstown repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in Randallstown, Maryland, typically range from $80 for a simple flame sensor replacement to $3,500+ for a heat exchanger, plus a $75–$200 diagnostic fee. With a median home age of about 50 years, many systems are aging and may require more frequent repairs. Maryland requires a mechanical permit for furnace work, and the state's electrification push (EmPOWER Maryland) encourages energy audits to unlock heat-pump rebates. For Randallstown's mixed-humid climate, a dual-fuel system (heat pump paired with furnace) is often recommended for efficiency and reliability.

What Randallstown code requires
Installing or replacing an HVAC system in Randallstown follows Maryland 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 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
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—
Strong statewide electrification push: EmPOWER Maryland requires a low-cost ($100) home energy audit to unlock the largest heat-pump/electrification rebates, and Maryland building energy code (IECC-based) increasingly favors heat pumps.

Furnace Repair in Randallstown, explained.
What influences furnace repair costs in Randallstown?
Repair costs vary by the component needing replacement—flame sensors are more affordable, while blower motors and control boards are pricier. Labor rates reflect local overhead, and the age of your furnace (many are 50+ years old) can make repairs more complex. Maryland's permit requirements add a small fee, and if you choose to upgrade to a high-efficiency unit, federal 25C tax credits (up to $2,000 for a heat pump) can offset costs.
Common furnace repairs in Randallstown
Flame sensor failure
A dirty or faulty flame sensor is a frequent issue in older furnaces, causing the system to shut off after ignition. Repair typically costs $80–$250.
Igniter problems
A worn-out igniter prevents the furnace from lighting. Replacement runs $150–$450, common in units over 10 years old.
Blower motor malfunction
The blower motor circulates warm air; failure leads to no heat or poor airflow. Repair costs $400–$1,500, often due to age or debris.
