Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residue in the air after rinsing and drying.

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 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.

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 proportionally to the recovered performance. And respiratory symptoms in sensitive individuals clearly reduce or disappear. 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 conditioning after winter or after several weeks of disuse, a smell of dampness, mould, or something unpleasant and organic escapes, lingering in the room for hours. The cause is biological. The internal 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 bacteria and fungi colonies to grow. The most worrying aspect isn't 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 worsen asthma. Children and the elderly are particularly susceptible. What you breathe every time the air conditioner is on is air passed through this colonised coil.

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 voided, and the installation may be declared illegal. The second detail is the gas charge. The quantity must be exactly as specified by the manufacturer for the installed copper length. A 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 using a precision electronic scale, not by estimating pressure as some quick installers do.

The price for a gas top-up in Barberà del Vallès typically ranges between €126 and €1602. The final figure depends on the condition of the property, materials, and working time. We always provide a fixed quote before starting. 30-day warranty on the service. If odours return, we repeat the service at no extra cost. Without measuring the copper, inspecting the facade, and evaluating the electrical panel, we cannot provide an honest quote. Free, no-obligation visit.
