The heat arrives, the nights become sticky and, Like every summerit’s time to wake up the old air conditioning. But this year something is not going well. When lighting it, the first breath of air does not bring relief: it smells weird, as a moisture enclosed, as forgotten. Is it just unpleasant or is there anything else? A problem that floats in the air. Some experts They have coincided In The Guardian that if the air conditioning smells weird, something is wrong. It is not a matter of comfort: there may be health consequences. “These smells are usually a sign that there is accumulation of mold or dirt in the filters or in the equipment of the equipment,” He explained For the British media Amy Li, a professor at the University of Waterloo and a researcher of interior air quality. According to Li, the air that comes out of a dirty team is not only cleaner than the one that enters: it can be loaded with mold spores. The origin of the problem. Every time the air passes through the cold serpentine (the evaporator coil), the steam is condensed. If that water does not drain well, it is stagnant and becomes a perfect broth for bacteria and fungi. And yes, from there those smells come, like They have detailed From Bosch. Can it be avoided? It would be as manual, basic and regular maintenance. Robert Polchinski, a professor at the City Tech College in New York, explained in The Guardian that he must be washed at least once per season. If the air is very loaded – for example, in urban or pet areas – it may be necessary to clean it more often. You also have to review the coils (interior and exterior), make sure that the device drains correctly and is well level. At the end of summer, you have to keep it well, without leaning or forcing it. In addition, if you are going to use the air after months, ventilate the house with the windows open for at least half an hour while it is running, According to a series of measuring tips. More innovative solutions. In addition to maintenance, innovation is also pushing more efficient solutions. Researchers They are developing New materials capable of better absorbing moisture and improving energy efficiency, which could lead to devices that cool more and spend less. Can everyone stink? According to an expert climate videomany users neglect the outer unit of The systems Splitwhere dust and humidity can also accumulate. Even pipes can absorb odors from inside the house and return them to the environment. A little known but effective solution is to install a siphon in the drain system, which avoids the return of odors. And, of course, maintain a cleaning routine every three or four months. In the case of portable or window equipmentmaintenance is more direct, but also more urgent: they are usually more exposed to dust, and many users store them badly in winter, damaging the compressor or leaving them in positions where the water is not drained correctly. The importance of counting the years. Air conditioning equipment has an estimated useful life of between 8 and 10 years. But if you notice that the light of the light rises without explanation, that the coils freeze or that the smell does not go with a thorough cleaning, the time has come to change it. It is not just a matter of efficiency: the oldest equipment consume more energy, pollute more and cool worse. A less toxic summer. The air conditioning can be a lifeguard in times of extreme heat, but it can also become a risk if neglected. Regular maintenance not only prevents bad odors: it improves energy efficiency, prolongs the life of the equipment and protects health.
