The air-to-water heat pump, also known as aerothermal heating, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It handles everything with a single unit, ideal for chalets and large homes. Its amortization period compared to a traditional gas + air system is 8 to 12 years in the local climate. A complete aerothermal installation is a serious project. It starts with calculating the home's thermal loads, sizing the unit according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and outdoor unit, and providing a fixed quote.

The electrical check includes nominal compressor consumption on startup and running, insulation testing of the wiring, condition of the starting capacitors (which degrade after the seventh or eighth year), and thermostat verification. The final disinfection with a certified product for air conditioning eliminates bacteria, fungi, and odours accumulated in the coil. This is what prevents the characteristic musty smell when you turn on the air conditioning after winter. The real economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or significant leak repair, costs several times more than annual maintenance over 5 consecutive years. Data from our own clients confirm that units with scheduled maintenance last 40 percent longer than units without any maintenance. Yes, but we locate the leak first. Recharging without repairing is illegal and a temporary fix. If there's a leak, we repair it first, then recharge.

Official manufacturer's warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer's warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual services. Electronic board failure due to power surges, moisture, or component ageing. This is relatively common in areas with thunderstorms, like the interior of Vega Baja in August. The repair may involve replacing the entire board or, if identifiable, replacing a specific capacitor or resistor. It largely depends on the model and parts availability.

The price for a split system installation in Sant Andreu de la Barca typically ranges between €148 and €1,224 as a guideline. The final figure depends on the property's condition, materials, and labour time, and we always finalize it after reviewing photos or – if you prefer – an on-site visit, with no obligation. Call us, message us on WhatsApp, or request a quote online – we'll respond in under 10 minutes during business hours. Older models without inverter technology start and stop abruptly at full power, which puts more stress on the compressor. Modern inverter models modulate smoothly and last longer. Their electronics are more sensitive, and from the seventh or eighth year onwards, board failures requiring whole module replacement begin to appear. The decision between repairing it or replacing the unit depends on the cost of the part versus the price of a comparable new unit.
