Furnace repair costs depend on the type of furnace, the nature of the problem, and whether parts need replacement. In the US, most repairs cost $150–$500, while a full furnace replacement runs $2,500–$7,000+. In Poland, repairs range from PLN 500–5,000. In the Netherlands, boiler repairs cost €200–€2,000. In Spain, caldera repairs run €80–€400 most cases, full replacement €1,500–€3,500 (mixta gas) or €5,500–€10,000+ (aerotermia). Regular maintenance can prevent most common failures and extend your furnace's lifespan by years.

Costs in the Netherlands
In the Netherlands, boiler (cv-ketel) repairs cost €200–€2,000. A service visit runs €80–€150. Common repairs include pump replacement (€200–€500), ignition system repair (€150–€400), and heat exchanger service (€300–€800). A full boiler replacement costs €1,500–€3,500 for a standard HR107 (high-efficiency) unit installed.
The Dutch heating market is transitioning away from natural gas. Many municipalities have plans to disconnect gas by 2050, making heat pumps an increasingly attractive alternative. Heat pump systems cost €5,000–€15,000 installed but qualify for ISDE subsidies of €1,500–€4,000. Regular annual maintenance (onderhoudsbeurt) costs €100–€175 and is recommended to maintain efficiency and warranty coverage. Use an installateur certified by Techniek Nederland.
What affects the cost?
- Type of repair — simple fixes (ignitor, thermostat) are cheap; major components (heat exchanger, blower) are expensive
- Furnace type — gas, oil, and electric furnaces have different parts and repair complexities
- Age of the unit — older furnaces may need hard-to-find parts or have multiple failing components
- Emergency timing — heating emergencies in winter carry premium rates of 1.5x–2x
- Warranty status — many parts are covered under manufacturer warranty for 5–10 years
- Efficiency upgrade — switching to a high-efficiency (95%+ AFUE) model costs more but saves on fuel
- Ductwork condition — if ducts are leaking or undersized, additional work may be needed
How to save
- Schedule annual maintenance — a $100–$150 tune-up prevents most costly breakdowns
- Change filters regularly — dirty filters cause 80% of furnace failures; replace every 1–3 months
- Get a diagnostic before deciding — some "failures" are simple fixes like a tripped safety switch
- Compare repair vs replacement — if repair costs exceed 50% of a new unit, replacement is usually smarter
- Claim tax credits and subsidies — high-efficiency replacements qualify for significant incentives
- Get multiple quotes for replacement — prices vary 30–50% between HVAC companies
- Consider a service contract — annual maintenance plans often include priority service and repair discounts
Frequently asked questions
How much does furnace repair cost?
The average furnace repair runs $150–$650 in the US, with the national average around $310. Service calls are $75–$150. Major repairs like blower motor replacement ($400–$1,500), heat exchanger ($1,500–$3,000), or control board ($300–$700) push costs higher. Annual tune-ups ($80–$200) prevent most costly repairs.
When should I repair vs replace my furnace?
Replace if: it's 15+ years old, repairs exceed 50% of replacement cost, you're paying for repairs every year, or it's not heating evenly. Replace cost: $3,000–$7,500 for gas furnaces, $4,000–$10,000 for heat pumps. Heat pumps qualify for federal tax credits up to $2,000.
Why does my furnace keep needing repairs?
Common culprits: dirty filters (change every 1–3 months), skipped annual maintenance, oversized or undersized for the home, or near end-of-life. Furnaces over 12 years old breaking down repeatedly are signaling it's time to replace, not keep repairing.
Is emergency furnace repair worth the cost?
In freezing weather, yes — pipes can freeze and burst within 6–8 hours of no heat. Emergency rates run 1.5×–2× standard ($150–$300/hr). If temps are above freezing and you have alternative heat (space heater), wait for business hours and save 30–50%.
