The condensate tray and drain are cleaned separately with descaling solution as they often accumulate limescale. If the drain is partially blocked, we clear it with a flexible hose. Finally, after drying all components, we apply a certified disinfectant product for air conditioning systems that eliminates residual bacteria and mould without leaving hazardous chemical residues. The next step is cleaning the coil, the part with thousands of thin fins where the refrigerant gas circulates. We apply a specific descaling solution for air conditioning, let it act for 15-20 minutes depending on the level of dirt. We rinse with moderate water pressure, protecting the rest of the unit with plastic to prevent water from entering where it shouldn't. The correct technique requires experience: too much pressure bends the fins and reduces performance, too little doesn't remove the dirt.

Air conditioning units 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 much of the year, which keeps the coil 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 loaded with salts contributes extra organic material to the filter. The most concerning aspect isn't the smell but what it indicates. The volatile compounds produced by these growing microorganisms are respiratory irritants and, in sensitive individuals or those with allergies, can cause headaches, nasal congestion, throat irritation, and worsen asthma. Children and the elderly are particularly susceptible. What you breathe every time the air conditioner is on is air that has passed through a colonised coil. This is one of the most common problems in domestic air conditioning on the Costa Blanca, and almost no one knows why it happens. When you turn on the air conditioner after winter or after several weeks of disuse, a smell of dampness, mould, or something unpleasant and organic emerges, lingering 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 colonies of bacteria and mould to grow.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective material to avoid stains. For premium units from recognised brands (Mitsubishi, Daikin, LG) that are 10-12 years old, repair is usually still worthwhile because their overall quality justifies extending their lifespan. For basic units that are 7-8 years old, replacement is almost always the reasonable decision. We arrive with a full set of instruments. Manometers for pressure, contact and infrared thermometers, electronic gas leak detector, multimeter, and clamp meter for electrical measurements. We also bring the specific diagnostic application for each brand to read error codes stored on the circuit board.

The price for a gas recharge in Vilassar de Mar typically ranges between €126 and €1602. The final amount depends on the property's condition, materials, and time spent. We always provide a fixed quote before starting. 30-day guarantee on the service. If odours return, we will repeat the service at no extra cost. Both. We always repair if the repair makes economic sense. If it exceeds 60 percent of the price of a new unit, we will tell you and you can decide.
