Non-toxic, with no chemical residues in the air after rinsing and drying. The next step is cleaning the coil, the part with thousands of thin fins where the refrigerant gas circulates. We apply a specific descaling product for air conditioning, letting it sit 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 won't remove the dirt.

Air conditioners on the Costa Blanca accumulate dirt significantly faster than in drier inland regions. Three factors combine. First, the average relative humidity in coastal areas is 70-75 percent for much of the year, keeping the coil constantly exposed to condensation. Second, Saharan dust arriving each summer leaves a thin but sticky layer that adheres to the fins and traps other contaminants. Third, sea air with suspended particles charged with salts adds 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 can worsen asthma. Children and the elderly are particularly sensitive. What you breathe every time the air conditioner is on is that same air passed through the colonised coil. It's one of the most common problems in domestic air conditioning on the Costa Blanca, and almost nobody 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 indoor coil of the air conditioner condenses moisture every time the unit cools. This permanent moisture, combined with the 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 fungi to grow.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid stains. Yes, it is mandatory in Spain for any handling of refrigerant gas. Without it, the manufacturer's warranty is void, and the installation may be declared illegal. Toshiba, Panasonic, and Fujitsu are a step down in price but not too much 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.

The price for gas recharging in Bufalà typically ranges between €126 and €1602. The final figure depends on the property's condition, materials, and the time required.
