The air-to-water heat pump, also called aerothermal heating, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climatise the home, and at the same time heats a domestic hot water tank of approximately 200 litres for use in showers and taps. It handles everything with a single unit, ideal for villas and large homes. Its payback 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 domestic hot water tank and the outdoor unit, and a fixed quote.

The electrical check includes the compressor's nominal consumption on startup and in operation, checking cable insulation, the condition of the start-up capacitors (which degrade from the seventh or eighth year), and verifying the thermostat. 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 actual economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or a major leak repair, costs several times more than annual maintenance over 5 consecutive years. Our own client data confirms that equipment with scheduled maintenance lasts 40 percent longer than equipment 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.

Manufacturer's official 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 checks. Electronic board failure due to power surges, moisture, or component aging. This is relatively common in areas with electrical storms like the interior of Vega Baja in August. The repair may involve replacing the entire board or, if localised, replacing specific components like a capacitor or resistor. It depends heavily on the model and parts availability.

The price for cleaning and maintenance in Santa Eulàlia typically ranges between €130 and €1296. The final amount depends on the property's condition, materials, and work time.

Older models without inverter technology start and stop abruptly at maximum 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 begin to appear, requiring the entire module to be replaced. The decision between repairing it or replacing the unit depends on the cost of the part versus the price of a new equivalent unit.
