Non-toxic, leaving no chemical residue in the air after rinsing and drying. The condensate tray and drain are cleaned separately with a descaling product 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 use that eliminates residual bacteria and fungi without leaving hazardous chemical residues.

It's 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 musty, mouldy, or unpleasant organic smell emerges that lingers in the room for hours. The cause is biological. The internal coil of the air conditioner condenses moisture every time the unit cools. This perpetual moisture, combined with organic dust entering through the filters and the moderate indoor temperature when the unit is off, creates the perfect environment for bacteria and fungi colonies to grow. After a deep sanitisation, the noticeable effects appear immediately. The unpleasant odour disappears from the very first use. The unit recovers between 10 and 25 percent of its original cooling performance (because a clean coil transfers heat better). Electricity consumption decreases proportionally to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear. 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 much of the year, keeping 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 laden with salts contributes extra organic material to the filter.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective material to avoid stains. Toshiba, Panasonic, and Fujitsu are a step below in price but not significantly in quality. They are a good option for tight budgets. More economical brands like basic Samsung, Hisense, or Hitachi function correctly for the first four or five years, but their efficiency and durability are lower, and they often require more maintenance. Mitsubishi Electric, Daikin, and LG are the three premium brands we install the most. Their inverter technology is very mature and they consume 40 percent less than older fixed-air units to produce the same cooling. Their outdoor noise level is clearly lower, which is important in communal courtyards where neighbours might complain. Their filters are of better quality and last longer between cleanings.

The price for gas refills in Centre (Mataró) typically ranges between €126 and €1602. The final amount depends on the condition of the property, materials used, and work time. We always provide a fixed quote before starting. 30-day warranty on the service. If the odours return, we repeat the service at no extra cost.
