Yes, we use certified products for domestic air conditioning. Non-toxic, with no chemical residues left in the air after rinsing and drying. Call us, text us on WhatsApp, or request your quote online — we'll reply in under 10 minutes during business hours. We clean the condensate tray and drain separately with a descaling product as they tend to 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 use, which eliminates residual bacteria and fungi without leaving hazardous chemical residues.

The most concerning aspect isn't the smell itself, but what it indicates. The volatile compounds produced by these growing microorganisms are respiratory irritants and, for 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 in every time the air conditioning is on is air that has passed through the colonised coil. Air conditioning units on the Costa Blanca accumulate dirt significantly faster than in dry inland regions. Three factors combine. Firstly, the average relative humidity in coastal areas is 70-75 percent for a large part of the year, which keeps the coil constantly exposed to condensation. Secondly, Saharan dust arriving each summer leaves a thin but sticky layer that adheres to the fins, trapping other pollutants. Thirdly, sea air with suspended particles loaded with salts adds extra organic material to the filter. After a deep sanitisation, the noticeable effects are immediate. The unpleasant odour disappears from the first use. 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 are clearly reduced or disappear.

2-3 hours per standard indoor unit. For multi-splits, add 1-2 hours per extra unit. We use protective materials to avoid stains. Mitsubishi Electric, Daikin, and LG are the three premium brands we install most frequently. Their inverter technology is very mature, and they consume 40 percent less than older fixed-speed air conditioners to produce the same amount of cooling. Their external noise level is clearly lower, which is important in communal courtyards where neighbours might complain. Their filters are of better quality and last longer between cleanings. The second detail is the gas charge. The quantity must be precisely what the manufacturer indicates for the installed copper pipe length. A gram more or less won't be noticeable immediately but, accumulated over 5 years, it results in 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 Sant Gervasi - Galvany typically ranges between €126 and €1602. The final figure depends on the property's condition, materials, and working time. We always provide a fixed quote before starting. 30-day warranty on the service. If the odours return, we will redo the service at no extra cost. Toshiba, Panasonic, and Fujitsu are a step down in price but not significantly in quality. They are a good option for tighter 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.
