A complete air source heat pump installation is a serious project. It starts with calculating the thermal loads of the home, sizing the unit according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the Domestic Hot Water (DHW) tank and the outdoor unit, and a fixed price quotation. The air-to-water heat pump, also called aerotermia, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to air-condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for shower and tap use. It handles everything with a single unit, ideal for chalets and large homes. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate.

The electrical check includes the nominal power consumption of the compressor during startup and operation, insulation check of the wiring, condition of the start-up capacitors (which degrade after the seventh or eighth year), and verification of the thermostat. Final disinfection with a certified air conditioning product eliminates accumulated bacteria, fungi, and odours in the coil. This is what prevents the characteristic musty smell when you turn on the A/C 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% longer than units with no maintenance at all. Gas leak at the outdoor unit connection, especially in units over 5 years old. Salt spray and thermal expansion/contraction from summer to winter loosen the fittings. A small leak progressively reduces the charge, and the unit cools less effectively each season. Repair involves detection with a professional gas detector, replacing the fitting or re-soldering the copper, vacuuming, and recharging.

Official manufacturer warranty (5-7 years) plus our labour warranty. 5-7 years manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour warranty and recommended annual servicing. Electronic board failure due to power surges, humidity, or component aging. This is relatively common in areas with electrical storms, like the interior of Vega Baja in August. Repair may involve replacing the entire board or, if traceable, replacing a specific capacitor or resistor. It depends heavily on the model and parts availability.

The price for cleaning and maintenance in Centre (Mataró) typically ranges between €130 and €1296. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. 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 after the seventh or eighth year, board failures start to occur, requiring replacement of the entire module. The difference between repairing it or replacing the unit depends on the cost of the part versus the price of a comparable new unit. Burned-out compressor in budget-range units with 6-9 years of intensive use. This is the most expensive breakdown. Compressor replacement costs a significant portion of the price of a new unit and is only worthwhile for premium units with a reasonable residual lifespan. For basic units, we usually recommend replacement.
