Five Common Air Cooler Problems and How to Fix Them

Professional Air Cooler Repair Services by Bizzz Services

Air coolers are essential, especially when the warm weather in Singapore becomes unbearable. They are an affordable and environmentally friendly option to keep spaces cool and comfortable without a staggering electricity bill associated with air conditioning. However, just like any appliance, air coolers also run into various issues and can turn your cooling solution into a frustrating experience. This article explores five common air cooler issues and how an air cooler repair service can assist in getting your appliance back to functioning properly. 

Water Leaks 

One of the most common issues with air coolers  is water leakage.This issue can be caused by several factors, such as a damaged water pump, clogged water distribution system, or a cracked water tank. Additionally, if the cooler is not properly levelled, water can leak from the overflow hole. 

To solve this issue, start by checking the water tank for cracks or damage. If the tank is intact, examine the water distribution system, which includes the pipes and pads, for any blockages or wear and tear. If the water pump is faulty, it may need to be replaced. Another vital step is ensuring the cooler is placed on a flat, level surface. However, it is best if you contact an air cooler repair service. Professionals can quickly diagnose the issue, replace faulty parts, and ensure your cooler is functioning correctly without any leaks. 

Not Enough Cool Air 

If your air cooler isn’t delivering enough cool air, it could be due to several reasons. Common causes include low water levels, dirty cooling pads, or an overloaded or malfunctioning fan motor. Additionally, high humidity levels can reduce the effectiveness of air coolers, as they rely on evaporation to cool the air. 

First, check the water levels and refill the tank if needed. Next, check the cooling pads to see if they’re dirty or clogged, and clean or replace them if necessary. Cleaning the pads regularly can significantly improve cooling efficiency. If the fan motor seems faulty, it may need lubrication or replacement, depending on how worn out it is. Consider using the air cooler in a well-ventilated space to enhance airflow, especially in areas with high humidity. If these steps don’t solve the problem, an air cooler repair service can provide a thorough inspection, addressing any underlying issues that may be affecting the cooling performance. 

Faulty Fan 

The fan is responsible for distributing cool air throughout the room. If it isn’t working properly, it could be due to a loose or broken fan belt, motor issues, or electrical problems such as a blown fuse or damaged wiring. 

First check the fan belt to see if it’s loose or broken, and if it requires tightening or replacement. Next, inspect the motor for any signs of wear or overheating. A motor that is not functioning correctly may need lubrication or could be burnt out and in need of immediate replacement. Additionally, check the electrical connections and fuse box to ensure there are no blown fuses or damaged wires. Electrical issues can be quite tricky, so it’s best to call an air cooler repair service as professional technicians can safely resolve electrical problems and ensure your fan is back up and running efficiently. 

Strange Odours 

An odd smell coming from your air cooler can be off-putting and may indicate a buildup of mould, mildew, or bacteria within the unit. This usually happens when the cooler hasn’t been cleaned regularly or if it’s been used in a damp environment where moisture can accumulate. 

To tackle this issue, start by thoroughly cleaning the water tank, cooling pads, and other components of the cooler. Use a mild detergent to disinfect and remove any mould or mildew. Ensure that all parts are completely dry before reassembling the cooler. Regular maintenance and cleaning from an air cooler repair service are key to preventing unpleasant odours. These technicians can conduct a thorough cleanup and inspect the cooler for any hidden issues that could be contributing to the odour. 

Unusual Noises 

Air coolers are designed to operate quietly, so if you start hearing unusual sounds such as grinding, rattling, or buzzing, it's a sign that something might be wrong with the appliance. These noises can be caused by a variety of issues, such as loose or worn-out parts or debris trapped in the fan or motor. 


First, turn off the cooler and unplug it before investigating the source of the noise. Check for any loose screws, bolts, or other components and tighten them as needed. If the noise is coming from the fan, inspect it for any debris that might be caught in the blades. Fan bearings that are worn out or improperly lubricated can also cause noise and if this is the case, they may need to be replaced or lubricated properly. To prevent further issues from coming up, call an air cooler repair service as these technicians have the necessary tools and expertise to quickly address and fix the issue.
