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, letting 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 areas it shouldn't. The correct technique requires experience: too much pressure bends the fins and reduces performance, too little doesn't remove the dirt.

After a deep sanitisation, noticeable effects appear immediately. The unpleasant odour disappears from the first run. 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 significantly reduce or disappear. 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 smell of damp, mould, or something unpleasant and organic comes out 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 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. The most concerning aspect isn't the smell but what it indicates. The volatile compounds produced by these microorganisms as they grow 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 the air that has passed through the colonised coil.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to prevent messes. Yes, it is mandatory in Spain for any refrigerant gas handling. Without it, the manufacturer's warranty is voided, and the installation may be declared illegal. The second detail is the gas charge. The amount must be exactly as indicated by the manufacturer for the installed copper length. One gram more or less won't be noticeable immediately, but accumulated over 5 years, it translates to a loss of performance. The charge is always done with a precision electronic scale, not estimated by pressure as some quick installers do.

The price for a gas top-up in La Verneda i la Pau typically ranges between €126 and €1602. The final figure depends on the property's condition, materials, and work time. We always provide a fixed quote before starting. 30-day guarantee on the service. If odours return, we repeat the service at no extra cost. Without assessing the copper piping, checking the facade, and evaluating the electrical panel, we cannot provide an honest quote. Free, no-obligation visit.
