Signs Your Evaporative Air Con Needs a Service

Evaporative air conditioning is a popular choice for people who live in hot and dry climates such as Perth, Australia. They are used extensively throughout the summer period to keep homes comfortable and provide an energy-efficient and cost-effective solution compared to traditional air conditioning units like ducted and split systems.

However, many evaporative air con owners don’t realise that their unit requires regular service, such as changing the water and cleaning the filter, to maintain its performance. There are signs you should look out for to know when it’s time to call in the professionals.

How does evaporative cooling work?

Simply put, an evaporative air cooler or evaporative air conditioner is a type of cooling system that works by pulling hot air through a wet filter to cool it down before it is circulated around the room. Unlike traditional air conditioners that use refrigerants, evaporative air coolers rely on the natural process of evaporation to cool the air of your home or office space.

When should I service my evaporative air con?

Here are some common signs that indicate your evaporative air conditioner may need service:

Reduced Cooling

The reduced cooling from an evaporative air conditioner indicates that the air circulated by the unit has become less cool than it used to be. This could signify that the system is not operating at its optimal efficiency. Some possible reasons for reduced cooling include:

  1. Clogged Filter: If the filter in your evaporative air conditioner is clogged with dust, dirt, or other particles, it can reduce the airflow and cooling performance of the unit.
  2. Low Water Level: When the water level in the evaporative air conditioner is insufficient, it may limit the water available for evaporation, causing a decrease in cooling capacity.
  3. Dirty Water: Dirty or contaminated water in the evaporative air conditioner can lower the efficiency of the evaporation process.
  4. Motor or Fan Issues: If the fan or motor in the evaporative air conditioner is malfunctioning, it may lead to decreased airflow and impaired cooling capabilities of the system.

Poor Air Flow

Reduced air flow from an evaporative air conditioner indicates that the quantity of air being circulated by the system has become less compared to its normal rate. This could be caused by several factors, including blocked ducts, clogged filters, limited surface area of the cooling pads or a congested water pump.

Leaks or Drips

If you see water leaking from your evaporative air conditioner, it could indicate a problem with the water distribution system or a clogged drain, other reasons why you may see leaking from your evap air con include:

1. Damaged water pump
2. Overfilled water tank
3. Improper installation

Unpleasant Smell

If you start to notice unpleasant odours coming from your evaporative air conditioner, it could indicate mould or bacteria growth in the filter or water tank. It’s important to call a service technician when you notice a foul smell coming from your unit, as mould and bacteria pose a health risk to you and your family.

Other reasons your evaporative unit might smell:

1. Poor ventilation
2. Degraded parts such as air filter pads
3. Musty air ducts

Increased Energy Bills

If your energy bills are rising unexpectedly, it could indicate that your evaporative air conditioner is no longer working as efficiently as it should or has not had a maintenance check for a long time; this can lead to higher energy consumption and higher bills.

Benefits of Regular Evaporative Air Cooler Maintenance

Regular maintenance of your evaporative air cooler is crucial for peak performance and longevity. Through regular inspections and cleaning, you can ensure that your unit is operating at its highest level and delivering you benefits that include:

  1. Cooling Performance: Regular service and maintenance of the unit can improve its cooling performance and ensure that it operates at its optimal level.
  2. Increased Energy Efficiency: Proper maintenance of an evaporative air cooler leads to lower energy usage, resulting in lower electricity bills.
  3. Extended Unit Life: Regular upkeep increases the lifespan of the evaporative air cooler and eliminates the need for expensive repairs or replacements.
  4. Improved Air Quality: Regular cleaning of filters and ducts enhances air quality and decreases the presence of allergens, dust, and other contaminants.
  5. Increased Comfort: An efficient evaporative air cooler creates a more comfortable living or working space by circulating cool and fresh air.
  6. Cost Savings: Regular maintenance detects and resolves potential issues before they worsen, leading to cost savings in the long term.

How often do I need to service my evaporative cooler?

We recommend a service every 12 months, or twice yearly if used frequently. Speak with us about when your evaporative air con might need a tune-up.

Do you offer replacement filter pads?

Yes, talk to us about the correct measurements for your unit or check out our spare parts page if you already know what you’re looking for.

Can I clean my evaporative air cooler filters myself?

It is not advised to clean an evaporative air conditioner yourself due to safety concerns. Cleaning the filters requires disassembling the unit and removing the dirty filters, which can be challenging and potentially dangerous for an inexperienced person. A professional technician is equipped with the proper tools, expertise, and training to perform the task effectively and safely.

A trained professional can check for signs of wear, perform necessary repairs and maintenance, and ensure your evaporative air cooler is operating correctly. Hiring a qualified technician gives you peace of mind that your unit will deliver clean and cool air effectively.
