6 Reasons Why Your Air Conditioning Unit is Not Cooling

Jul 29, 2021 | Air Conditioning

On hot summer days (and nights), air conditioning is essential to keep you feeling comfortable. If your air conditioning unit is not working properly and not cooling your property, you need to sort it out quickly. Luckily, the reasons for this are usually easy to identify.

1. Clogged Air Filter

The air filter’s purpose is to trap airborne particles so they don’t cause damage to the air conditioning unit. However, over time, the filter can become clogged with dirt, restricting the air flow and may cause the evaporator coil to freeze. It is advisable to clean the filter monthly to prevent this from happening.

2. Thermostat Problems

Although it can seem too obvious, the air conditioner may not be cooling because it is set at too high a temperature. If so, set it correctly, otherwise, it may not be working properly. Problems may occur if the thermostat needs to be cleaned, is positioned incorrectly or has batteries that need replacing. Seek professional help if you’re not sure.

3. Malfunctioning Air Conditioning Units

The condenser is the external unit that converts hot air to cool air, and it won’t work properly if it is clogged with dirt or there is some obstruction. Clean it frequently and remove plants and other items immediately surrounding it to prevent these problems.

The evaporator is the inside unit that transfers warm air to the external condenser, and any dirt in the unit will reduce its efficiency. Inspect it regularly and ensure it’s clean.

4. Faulty Fan Motors

Fans within the system dissipate heat from the external unit and distribute cooled air internally. Any that are not working correctly will cause the system to be inefficient.

5. Damaged Compressor

The compressor manages the refrigerant flow between the internal evaporator and the external condenser. If the compressor is damaged, it will be unable to cool the air correctly and needs to be replaced.

6. Low Refrigerant

The refrigerant is the fluid inside the air conditioning unit that absorbs heat from the air. A low refrigerant level may indicate a leak, which you can often detect by a bubbling noise or a build-up of ice on the external unit. If so, it needs to be fixed by a professional to ensure the system cools correctly.

Although you can inspect and clean the system yourself, you may not always be aware of what to do. Additionally, certain air conditioning maintenance and repair jobs must be undertaken by qualified technicians.
