In a previous article dedicated to cleaning air conditioners we underlined the importance of starting with routine maintenance in advance moment in which the devices will actually be activated. It's a small precaution, but it could make a difference, especially if we realize that the air conditioner isn't cooling.
In fact, turning on the air conditioner in the middle of summer to cope with a stifling heat wave and discovering that the device isn't working can turn into a minor drama.
Tra On the other hand, it is always preferable, where necessary, to avoid requesting emergency interventions from a specialized technician, as you may risk not finding availability or, in some cases, paying a higher price. In any case, if you find yourself faced with an air conditioner that doesn't cool, it's best not to worry, because the solution may be within reach. So, let's go step by step and try to data-mce-fragment="1"> Understand what to do when the air conditioner isn't cooling by analyzing 4 possible causes of the problem.
1. Dirty Air Filter
The first and most common possible cause of an air conditioner that doesn't cool could be a very simple one: an air filter that's too dirty.
In fact, if the filter is dirty or clogged, various problems could occur, such as blocking the passage of hot and cold air. inside the ducts, thus interfering with the thermostat's proper functioning. A filter that's too dirty could also cause the evaporator coil to freeze, blocking the passage of outgoing cold air. Therefore, the first piece of advice we can give if the air conditioner isn't cooling is Check the condition of the filter, and clean it.
2. Dirty or broken outdoor unit
In addition to the internal split filter, dirt accumulation in the outdoor unit, the one installed on the outside wall of the building, may also be blocking the emission of cold air.
This does not apply, obviously, to air conditioners without an outdoor unit.
Therefore, carefully and taking the necessary precautions, reach the outdoor unit of your air conditioner and data-mce-fragment="1">Make sure there's nothing obstructing it or hindering its operation.
If it's just a buildup of dirt, simply cleaning it is sufficient, but if that doesn't work, it could be a damage to the fan or motor.
In this case, all that's left to do is contact a specialized technician.
3. Thermostat or remote control settings
Another possible cause that prevents the air conditioner from cooling adequately is the thermostat or remote control settings.
In fact, especially if you use the device in the winter to generate warm air, the settings may have remained the same as those for the cold months.
At this point, all you have to do is Change the settingsand select the one suitable for cooling. Typically thesun symbolindicates the emission of hot air, while the snowflake that cold.
4. Refrigerant
The fact that the air conditioner doesn't cool is often attributed to the consumption of the refrigerant inside it, but this is a mistake (often made in bad faith by technicians).
In fact, the circuit in which the refrigerant flows is closed and cannot be consumed; Instead, it could be a coolant leak – rare, but possible – due to damaged hoses or improper installation. In these cases, it's possible to locate and repair the leak, then add new coolant. But, if there's a leak and you simply refill the fluid without repairing it,you're doing something absolutely useless.
Therefore, if the technician suggests recharging the air conditioner as the solution to the problem, perhaps it's time to contact another, more honest and knowledgeable professional.
Buy a new air conditioner
If, despite cleaning, routine and extraordinary maintenance, and repairing the potential damage, the problem isn't solved, and the air conditioner still isn't cooling satisfactorily. Perhaps it's time to replace it and buy a new one.
