Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residue in the air after rinsing and drying.

The next step is cleaning the coil, the component with thousands of thin fins where the refrigerant circulates. We apply a specific descaling product for air conditioning, letting it act for 15-20 minutes depending on the level of dirt. We rinse with moderately pressured water, protecting the rest of the unit with plastic sheeting to prevent water from entering unintended areas. Correct technique requires experience: excessive pressure can bend the fins and reduce efficiency, while too little pressure won't remove the dirt effectively.

This is one of the most common problems with domestic air conditioning on the Costa Blanca, and few people know why it happens. When you turn on the air conditioning after winter or after several weeks of non-use, an unpleasant musty, mouldy, or organic smell emerges that lingers in the room for hours. The cause is biological. The indoor coil of the air conditioner condenses moisture every time the unit cools. This constant moisture, combined with organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates the perfect environment for bacterial and fungal colonies to grow. Air conditioners on the Costa Blanca accumulate dirt significantly faster than in dry inland regions. Three factors combine. Firstly, the average relative humidity in coastal areas is 70-75 percent for a large part of the year, meaning the coil is constantly exposed to condensation. Secondly, Saharan dust arriving each summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Thirdly, sea air with suspended particles laden with salts contributes extra organic matter to the filter. After a deep sanitisation, the noticeable effects are immediate. The unpleasant odour disappears from the first use. The unit recovers between 10 and 25 percent of its original cooling performance (as a clean coil transfers heat more effectively). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear entirely.

2-3 hours per standard indoor unit. For multi-split systems, add 1-2 hours per extra unit. We use protective materials to avoid making a mess. 5-7 years manufacturer's warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour guarantee and recommended annual check-ups. Electronic board failure due to power surges, moisture, or component aging. This is relatively common in areas with electrical storms, such as the Vega Baja interior in August. Repair may involve replacing the entire board or, if identifiable, replacing a specific capacitor or resistor. It depends heavily on the model and parts availability.

The price for cleaning and maintenance in Les Tres Torres typically ranges from €130 to €1296. The final figure depends on the property's condition, materials used, and time spent. We always provide a fixed quote before starting. 30-day guarantee on our service. If the odours return, we'll repeat the service at no extra charge.
