The air-to-water heat pump, also known as aerothermal energy, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to regulate the home's temperature. Simultaneously, it heats a domestic hot water tank, approximately 200 litres, for use in showers and taps. It resolves everything in a single system, ideal for detached houses and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in this region's climate. A complete aerothermal installation is a significant project. It begins 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 real economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or a major leak repair, costs many times more than annual maintenance over 5 consecutive years. Data from our regular clients show that units with scheduled maintenance last 40% longer than those without any maintenance. Yes, but we locate the leak first. Recharging without repairing is illegal and only a temporary fix. If there's a leak, we repair it first, then recharge. We install 1x1 splits in individual rooms and 2x1, 3x1, or 4x1 multi-splits when multiple spaces need conditioning from a single outdoor unit. Most apartments in the area, particularly those built in the 80s and 90s with enclosed balconies, require multi-splits because the facade cannot accommodate multiple outdoor units.

5-7 years official manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual servicing. Our network includes certified F-Gas technicians, which is the only legal requirement for handling refrigerant gas in Spain. This is not a minor detail. If someone installs or repairs your air conditioning without certification, the manufacturer's warranty is void, and a regional authority inspection could result in a fine for the owner. This is the typical summer scam. They offer to install the air conditioning for €200 less because a friend who's an electrician or plumber will do it. No F-Gas certification. The installation might work fine for the first year, but if there's a gas leak, you won't be able to claim from the manufacturer. Initial gas charging with an electronic scale, vacuuming to -700 mbar, and leak testing are mandatory. Without them, the unit's lifespan is halved.

The cost of relocating units in Santa Coloma de Gramenet typically ranges from €139 to €1638. The final price depends on the property's condition, materials used, and work time involved. We always provide a fixed quote before starting. Select the service you need for more details and to request a quote. The quote is free and always provided after an on-site visit. Without a prior visit, no one can give an honest price for air conditioning services: copper pipe distances must be measured, the outdoor unit's location checked, and the electrical panel inspected. A price advertised online for €100 is invariably a bait.
