A complete aerothermal installation is a significant project. It starts with calculating the thermal loads of the home, sizing the equipment 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 providing a fixed price. 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 air-condition the home. Simultaneously, it heats a domestic hot water tank of approximately 200 litres for showers and taps. It handles everything with a single unit, ideal for detached houses 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 at startup and running, insulation check of the wiring, condition of the startup capacitors (which degrade from the seventh or eighth year), and verification of the thermostat. The final disinfection with a certified air conditioning product 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 for 5 consecutive years. Data from our own clients confirm that equipment with scheduled maintenance lasts 40 percent longer than equipment without any maintenance. Gas leak at the outdoor unit connection, especially in equipment over 5 years old. Salt spray and thermal expansion/contraction from summer to winter loosen the connections. A small leak progressively reduces the charge, and the unit cools less effectively each season. The repair involves detection with a professional gas detector, replacement of the fitting or re-soldering the copper, vacuuming, and recharging.

Official manufacturer's warranty (5-7 years) plus our labour coverage. 5-7 years from the manufacturer, depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual checks. Failed electronic board due to power surges, humidity, or component aging. This is relatively common in areas with electrical storms, such as the interior of Vega Baja in August. The repair may involve replacing the entire board or, if locatable, replacing specific capacitors or resistors. It depends heavily on the model and parts availability.

The price for cleaning and maintenance in Badalona typically ranges between €130 and €1296. The final amount 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 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, printed circuit board failures begin to appear, requiring the entire module to be replaced. The difference between repairing it or replacing the unit depends on the cost of the part versus the price of an equivalent new unit. Burned-out compressor in economy-range equipment with 6-9 years of intensive use. This is the most expensive breakdown. Replacing the compressor costs a significant portion of the price of a new unit and is only worthwhile for premium equipment with a reasonable remaining lifespan. For basic equipment, we usually recommend replacement.
