CV-ketel repareren cost in Spanje: typically €40–80 as of 2026. The exact price depends on job scope, materials, urgency (emergency and after-hours work costs more), and local demand. Compare verified local pros and request free, no-obligation quotes for real prices on your job.
Spanish caldera (boiler) repairs run €80–€400 for the most common service calls, with a desplazamiento + diagnóstico of €40–€80 typically credited toward the repair if you proceed. Common repairs: termopar / electrode €100–€180, vaso de expansión €120–€220, bomba (pump) €180–€350, intercambiador (heat exchanger) €350–€700. A full caldera mixta de gas replacement costs €1,500–€3,500 installed for high-efficiency models (Vaillant, Junkers/Bosch, Saunier Duval); a high-end condensation model with smart thermostat €3,000–€4,500. For aerotermia (heat-pump) conversion the all-in cost runs €5,500–€10,000+ but IDAE rebates under Real Decreto 477/2021 cover 35-50%. The RITE (Real Decreto 178/2021) mandates annual maintenance for any caldera de gas — the revisión anual costs €60–€90 and the installer logs it in the manuals; skipping it voids both the manufacturer warranty and the home insurance's gas-leak coverage. Every 5 years a stricter inspección oficial (€80–€120) is required for natural-gas appliances, performed by an authorised IT (Instalador Térmico). On Spain's heating-season schedule, Comunidad Valenciana's mild winter means most apartments use combi boilers only for hot water 9 months a year, so demand peaks November-February rather than year-round as in colder regions.

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
- 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
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.
