There's nothing worse than turning on your air conditioning on a hot day and realizing that it's not cooling the room as it should. This problem can have several causes, from dirty filters to more serious failures in the cooling system. Before calling a technician, check out some simple checks and solutions that can help restore your appliance's operation.
1. Check the Air Filter
Dirty filters are one of the main causes of reduced air conditioning efficiency. If they are clogged with dust and dirt, the air flow is compromised, reducing the cooling capacity. The solution is simple: remove the filters and wash them with water and mild soap, letting them dry completely before replacing them.
2. Adjust the Temperature and Operating Mode
It may seem obvious, but often the problem lies in the incorrect configuration of the remote control. Make sure the unit is in "Cool" mode and the temperature is set to an appropriate level, usually between 22°C and 24°C for efficient cooling.
3. Check the Outdoor Unit (Condenser)
The air conditioner's outdoor unit needs space and adequate ventilation to dissipate heat. If it is obstructed by dust, leaves or other objects, it may lose efficiency. Clean the outside and make sure nothing is blocking the air circulation.
4. Check the Refrigerant Gas
If the unit is working but does not cool the room, there may be a leak or low refrigerant gas level. This problem should be resolved by a specialized technician, who will check and recharge the gas if necessary.
5. Check for Electrical Problems
Electrical faults, such as tripped circuit breakers, loose cables or burned components, can prevent the unit from working properly. If your air conditioner won’t turn on or is experiencing a drop in performance, you may need an electrician to inspect the wiring.
Conclusion
If your air conditioner has stopped cooling, try these solutions before calling a technician. Cleaning the filters, checking the settings, ensuring the outdoor unit is well ventilated, and inspecting for electrical faults are essential steps to keeping your unit running smoothly. If the problem persists, a qualified professional can identify and fix more complex faults.
