  3. What to do if your air conditioner stopped cooling: common causes and practical solutions

What to do if your air conditioner stopped cooling: common causes and practical solutions

Imagine a hot summer day in Cascais, with the sun shining brightly, and suddenly your air conditioner stops working. The heat starts to take over the room, and you don't know where to begin solving the problem. But don’t worry! There’s no need to panic. If your air conditioner stopped cooling, let's explore some common reasons for this and possible solutions.

Check if the filter is dirty

One of the most frequent reasons for an air conditioner to stop cooling is a dirty filter. It may seem simple, but many forget that the appliance's filter needs regular maintenance. When it’s clogged with dust, it blocks the airflow and compromises cooling capacity. Besides impacting performance, it can also increase energy consumption.

Try to remember the last time you cleaned or replaced the filter. If it’s been a while, it’s time to clean it or, depending on its condition, replace it. If you're considering more professional alternatives, don’t hesitate to search for air conditioning installations in Lisbon, which offer comprehensive maintenance services.

Electrical issues or thermostat problems

If checking the filter doesn't solve the issue, another cause could be related to electrical failures or problems with the thermostat. The air conditioner might not be receiving the correct amount of power, which affects its functionality. Ensure the device is properly plugged in and the thermostat is set to the desired temperature.

If the problem persists, it might be a good idea to seek technical assistance. Many companies offer maintenance services, and it could also be an opportunity to think about buying an air conditioner with installation in Cascais, ensuring a more efficient and suitable system for your space.

Refrigerant gas leak

One of the more worrying causes is a refrigerant gas leak. The gas is essential for the proper functioning of the air conditioning system, and if there’s a leak, the appliance will simply stop cooling. This problem requires specialized attention and should not be handled without professional assistance.

A qualified air conditioning technician can identify the problem and carry out the necessary repairs. Otherwise, the malfunction will continue, and your system will consume more energy without delivering the desired benefits. So, if you notice weaker or no cooling, contact a trusted company to assess the situation. And, of course, keep in mind the price of air conditioning installation in Sintra, which can vary depending on the required service.

How to prevent air conditioning problems?

Keeping your air conditioner running efficiently requires some care. Periodic maintenance is essential, and small actions like regularly cleaning the filter and checking electrical circuits can make a big difference in the appliance’s performance. Additionally, it’s important to choose a quality unit that fits the size and needs of your space.

If you’re thinking of replacing or purchasing a new air conditioner, remember to consider all options and rely on experienced professionals for installation and maintenance. After all, the weather in Cascais can be unpredictable, and no one wants to endure a stifling summer due to a faulty cooling system.

Here are a few tips to keep your air conditioner in good condition:

  1. Clean or replace the filter regularly (at least every 3 months).
  2. Check the thermostat to ensure it’s working properly.
  3. Have an annual inspection to prevent major issues.
  4. Hire a qualified company to maintain the unit.

Maintaining your air conditioner not only extends the appliance’s lifespan but also helps save energy. A well-maintained system means fewer repair costs and more comfort on hot days.

The right choice for your comfort

Choosing an air conditioner that suits your needs is the first step to ensuring your comfort. Cascais is a wonderful city with a pleasant climate, but when the heat kicks in, having a reliable appliance makes all the difference. Don’t forget to consider all options, whether for maintenance or buying a new unit. Lastly, when thinking about upgrading your system, remember to compare the price of air conditioning installation in Sintra, to make a smart investment and ensure a cool and comfortable summer.
