The next step is cleaning the coil, the part with thousands of thin fins through which the refrigerant gas circulates. We apply a specific descaling product for air conditioning, leaving it to 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 fails to remove the dirt.

After a deep sanitisation, the noticeable effects appear immediately. The unpleasant odour disappears from the first use. The unit recovers between 10 and 25 percent of its original cooling performance (because the clean coil transfers heat better). Electricity consumption decreases in proportion to the recovered performance. And respiratory symptoms in sensitive individuals are clearly reduced or disappear. The most concerning aspect is not the smell itself, 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 worsening of asthma. Children and the elderly are susceptible. What you breathe every time the air conditioner is on is that air passed through the 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 non-use, a smell of dampness, mould, or something unpleasantly organic emanates and 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 material to prevent 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 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 tend to require more maintenance.

The price for a gas refill in Montornès del Vallès typically ranges between €126 and €1602. The final amount depends on the condition of the property, materials, and time required. We always provide a fixed quote before starting. 30-day warranty on the service. If the odours return, we will repeat the service at no extra cost.
