Why Choose an Evaporative Cooling System? 

A Highly Energy-Efficient Option: A ducted evaporative cooling system is a more energy-efficient way to cool your entire home than refrigerated air conditioning. While refrigerated systems use a refrigerant and compressor, evaporative coolers use the natural process of water evaporation to lower the indoor temperature. By only using energy for the fan and pump and not providing heating, evaporative coolers offer significant energy savings.

Evaporative Cooling Is Eco-Friendly: Evaporative air conditioners are much more eco-friendly than traditional refrigerated air conditioners. Refrigerated air conditioners use refrigerants that can contribute to global warming by depleting the ozone layer. On the other hand, evaporative air conditioners use water as their cooling agent, which is a far more sustainable and environmentally responsible option. Additionally, evaporative air conditioners consume less energy, producing no carbon emissions and reducing their environmental impact. Homeowners who want to minimise their carbon footprint should consider using an evaporative air conditioning system. A

Budget-Friendly Option: Evaporative air conditioners are often more cost-effective than traditional refrigerated air conditioners. They require less energy, are easier to install and maintain, and don't require expensive refrigerants. This results in lower running evaporative air conditioning prices over the system's lifespan. According to Consumer website Choice, evaporative cooling cost can be between $200 and $300 a year, while refrigerated air conditioners typically cost between $400 and $500 a year. This makes ducted evaporative air conditioners popular for Australian customers seeking affordable cooling solutions.

Improved Air Quality: Evaporative air conditioners can enhance indoor air quality by drawing in fresh outside air and cooling it using water-soaked pads. This process helps remove stale air and reduce pollutants, odours, and allergens. This can be especially beneficial for people with allergies or respiratory issues. Keep doors and windows open using an evaporative air conditioner to ensure effective air circulation.

Optimal Humidity Levels: Evaporative air conditioners can increase the moisture content in the air, which can benefit people with respiratory problems, asthma, dry skin, and eye irritation. Dry climates can worsen these conditions, so maintaining balanced humidity is important. This can help reduce dry skin, eye irritation, and respiratory issues, protect wood furniture and flooring, minimise static electricity, and create a more comfortable living environment.

Minimal Maintenance Required: Evaporative air conditioners are generally easier to maintain than refrigerated air conditioners. They have fewer components, making them simpler to operate and maintain. Cleaning and maintenance tasks are typically straightforward, such as removing and cleaning the cooling pads and filters. Additionally, using water as the cooling agent makes it easy to detect and repair leaks. This low-maintenance aspect makes evaporative air conditioners attractive for those seeking a hassle-free cooling solution. 

How Much Does Evaporative Cooling Cost? 

Before buying an evaporative cooling system, consider the evaporative cooling price of the unit itself, installation, and ongoing operation. Here's what you need to know.
