Why is the AC not as cold as before? Here are the causes and solutions!

An air conditioner that isn’t cooling can be very annoying, especially during unbearably hot weather. There are a few common reasons why your air conditioner might not be working properly and the solutions you can try on your own before calling a technician.


1. Dirty Air Filter

Cause: A dirty air filter can restrict airflow and reduce the efficiency of your air conditioner. When the air filter is filled with dust and dirt, cool air can’t flow properly through the system, causing the air conditioner to work harder but produce less cooling.

Solution: Clean or replace the air filter regularly. Ideally, the air filter should be cleaned every 3 months to keep the airflow smooth and the efficiency of your air conditioner.


2. Low Refrigerant or Leaking

Cause: Low refrigerant levels or leaks in the refrigerant system can prevent your air conditioner from cooling the room effectively. Refrigerant is the substance responsible for cooling the air, and without enough of it, your air conditioner won’t be able to function properly.

Solution: Call a professional technician to check and refill the refrigerant and fix any leaks. Only licensed technicians should handle refrigerants because they require special handling.


3. Dirty Condensor or Evaporator

Cause: Dirt that builds up on the condenser or evaporator can inhibit heat transfer. These two components are essential to the cooling process, and dirt that builds up there can cause your AC to lose efficiency.

Solution: Clean the condenser and evaporator regularly. If you’re not sure how to do it, it’s best to contact an AC technician to ensure that the cleaning is done correctly and safely.


4. Thermostat Problems

Cause: A faulty or improperly calibrated thermostat can cause your AC to not work properly. A faulty thermostat may not be able to accurately sense the room temperature, which can interfere with the AC performance.

Solution: Check the thermostat settings and make sure they’re at the desired temperature. If the problem persists, consider replacing the thermostat with a newer, more accurate model.


5. Compressor Problems

Cause: A faulty compressor can restrict the circulation of refrigerant in your AC system. The compressor is the heart of the cooling system, and if it fails, the entire system will be affected.

Solution: If the compressor is damaged, it is best to contact an AC technician immediately for repair or replacement. Do not attempt to repair the compressor yourself as this can be dangerous and worsen the damage.


6. Blockage in the Air Duct

Cause: Blockage in the air duct can reduce the flow of cool air into the room. Dust, dirt, or other foreign objects can clog the duct, inhibiting cooling.

Solution: Check and clean the air duct from dust and dirt. Make sure there are no foreign objects blocking the duct to maintain smooth air flow.


7. Overheating Outdoor Unit

Cause: Outdoor units that are exposed to direct sunlight or blocked by other objects can overheat, reducing the performance of the AC.

Solution: Make sure the outdoor unit is installed in a shady and unobstructed location. If necessary, add a shade to reduce exposure to direct sunlight. This will help keep the outdoor unit cool and functioning efficiently.


8. Misuse

Cause: Improper use of the AC, such as opening windows or doors while the AC is on, can reduce cooling efficiency. This causes cold air to escape and hot air to enter, making the AC work harder.

Solution: Close windows and doors while the AC is on to keep the cold air inside. This will help the AC work more efficiently and cool the room better.



Conclusion

Knowing the common causes of an AC that is not cold and how to fix it can help you maintain optimal AC performance. Some problems can be solved with simple steps such as cleaning the air filter or making sure the outdoor unit is not exposed to direct sunlight. However, for more serious problems such as refrigerant leaks or compressor damage, it is better to call a professional technician. With proper maintenance, your AC will function properly again and provide maximum comfort in your home. Don't hesitate to check your AC regularly and do routine maintenance to keep it in top condition.
