A complete aerothermal installation is a serious 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 DHW tank and outdoor unit, and a fixed quote. The air-to-water heat pump, also called aerothermal, 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 at the same time heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves 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 nominal compressor consumption on startup and running, insulation check of the wiring, condition of the start capacitors (which degrade from the seventh or eighth year), and thermostat verification. Final disinfection with a certified air conditioning product eliminates bacteria, fungi, and odours accumulated in the coil. This prevents the characteristic musty smell when you turn on the air conditioning after winter. The real economic savings from maintenance are easily calculated. A serious air conditioning breakdown in August, involving compressor replacement or significant leak repair, costs several times more than annual maintenance over 5 years. Data from our own clients confirms that units with programmed maintenance last 40 percent longer than units with no maintenance. Fault localization using certified instruments before proposing a repair.

Official manufacturer's warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer's official warranty depending on brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual reviews. Electronic board failure due to power surges, moisture, or component ageing. 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 locatable, replacing the specific capacitor or resistor. It heavily depends on the model and parts availability.

The price for cleaning and maintenance in El Masnou typically ranges between €130 and €1296. The final amount depends on the property's condition, materials, and time spent. 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 from the seventh or eighth year, board failures start to appear requiring the replacement of the entire module. The difference between repairing it or changing the unit depends on the cost of the part versus the price of a comparable new unit. Burned-out compressor in economy-range units with 6-9 years of intensive use. This is the most expensive breakdown. Replacing the compressor costs a significant portion of a new unit's price and is only worthwhile for premium units with a reasonable remaining lifespan. For basic units, we usually recommend replacement.
