Welcome to Pistonudos, where we care about providing you with the best information to solve problems with your air conditioning equipment. In this article, we will address the possible causes and solutions when an air conditioner does not cool properly, as well as tips and recommendations to improve its performance. Read on for all the information you need!

1. Lack of maintenance

One of the main reasons why an air conditioner does not cool properly is the lack of proper maintenance. Over time, air filters become clogged with dirt and dust, hindering airflow and reducing equipment efficiency. Additionally, the evaporator and condenser coils can accumulate dirt, which also affects their performance.

The solution to this problem is to perform regular maintenance on your air conditioner. Clean or replace the air filters according to the manufacturer's recommendations, and be sure to clean the coils regularly. If you don't feel comfortable doing it yourself, you can always hire a professional to do the maintenance for you.

2. Coolant leaks

Another common cause of an air conditioner not cooling properly is refrigerant leaks. The refrigerant is responsible for absorbing heat from the air and cooling it, so if there is a leak, the system will not be able to cool properly. You can detect a refrigerant leak if you notice that the air conditioner takes longer to cool down or if you see oil stains around the pipes or connections.

If you suspect that you have a refrigerant leak, it is important that you call a specialized technician to repair the leak and recharge the refrigerant. Trying to do it yourself can be dangerous and further damage your computer.

3. Problems with the compressor

The compressor is the heart of the air conditioning system, since it is responsible for compressing the refrigerant and pumping it through the system. If the compressor is faulty or not working properly, the air conditioner will not be able to cool properly.

If you suspect that the compressor is the problem, it is recommended that you call a technician to have it checked and repaired if necessary. The compressor is an expensive and complicated part to replace, so it's best to leave it to a professional.

4. Electrical problems

Electrical problems can also be the cause of an air conditioner that doesn't cool properly. Faulty wiring, a blown fuse, or damaged switch can affect the operation of the equipment.

If you suspect there is an electrical problem, be sure to check the fuses and breakers. If you can't find any abnormalities, it is recommended that you call an electrician to check the wiring and fix any electrical problems that may be affecting the performance of the air conditioner.

Frequently Asked Questions (FAQs)

1. Why does my air conditioner emit an unpleasant odor?

If your air conditioning emits an unpleasant odor, it may be due to the accumulation of dirt and bacteria in the filters and coils. The solution to this problem is to clean or replace the air filters and to deep clean the coils. If the smell persists, it is recommended that you call a technician to check the equipment and fix the problem.

2. What is the ideal temperature for an air conditioner?

The ideal temperature for an air conditioner can vary according to personal preference, but it is generally recommended to keep it between 22°C and 24°C for a cool and comfortable environment. However, it is important to note that setting the temperature too low can increase power consumption and affect equipment efficiency.


In short, if your air conditioner isn't cooling properly, it's likely due to lack of maintenance, refrigerant leaks, compressor issues, or electrical issues. Performing regular maintenance, calling a specialized technician for repairs, and checking for electrical problems are the best ways to fix these problems and improve the performance of your air conditioner.
