We clean the condensate tray and drain 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 systems that eliminates residual bacteria and fungi without leaving hazardous chemical residues. The next step is cleaning the coil, the part with thousands of thin fins through which the refrigerant gas flows. 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 sheeting 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 doesn't remove the dirt. Yes, we use certified products for domestic air conditioning. They are non-toxic, leaving no chemical residues in the air after rinsing and drying.

Air conditioners on the Costa Blanca accumulate dirt much faster than in dry inland regions. Three factors combine. Firstly, the average relative humidity in coastal areas is 70-75 percent for most of the year, which keeps the coil constantly exposed to condensation. Secondly, Saharan dust that arrives every summer leaves a thin but sticky layer that adheres to the fins and traps other pollutants. Thirdly, the sea air with suspended particles loaded with salts contributes extra organic material to the filter. This is 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 conditioning after winter or after several weeks of disuse, a damp, mouldy, or unpleasant organic smell emerges that lingers in the room for hours. The cause is biological. The indoor coil condenses moisture every time the unit cools. This constant humidity, combined with the 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 worrying 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 exacerbate asthma. Children and the elderly are particularly susceptible. What you breathe every time the air conditioning is on is air passed through the colonised coil.

2-3 hours per standard indoor unit. For multi-split systems, 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. Mitsubishi Electric, Daikin, and LG are the three premium brands we install most often. Their inverter technology is very mature, and they consume 40 percent less than older fixed-speed air conditioners to produce the same cooling. Their outdoor noise level is significantly lower, which is important in shared courtyards where neighbours might complain. Their filters are of higher quality and last longer between cleanings.

The price for a heat pump installation in Sant Gervasi - la Bonanova generally ranges between €160 and €1440. The final cost depends on the property's condition, materials used, and working time. We always provide a fixed quote before starting. Toshiba, Panasonic, and Fujitsu are a step below in price but not significantly in quality. They are a good option for tighter budgets. More economical brands like Samsung, Hisense, or basic Hitachi models function correctly for the first four or five years, but their efficiency and durability are lower, and they typically require more maintenance. 30-day service guarantee. If odours return, we repeat the service at no extra cost.
