Evaporative air conditioners, also known as swamp coolers, offer a cost-effective way to beat the heat. However, their reliance on water makes them susceptible to mould growth. This article will guide you through identifying, preventing, and remediating mould in your evaporative air conditioner.
Identifying Mould in Your Evaporative Air Conditioner
Mould manifests in various ways. You might notice:
- Visible mould: This is the most obvious sign, appearing as fuzzy, often dark-colored patches on the pads, water trays, or other components. Common colours include black, green, grey, or brown.
- Musty odour: A persistent, unpleasant smell emanating from the unit is a strong indicator of mould, even if you can't see it.
- Respiratory issues: If you or others in your household experience symptoms like coughing, sneezing, or wheezing after using the evaporative cooler, mould could be the culprit. This warrants immediate attention.
Preventing Mould Growth in Your Evaporative Air Conditioner
Prevention is always better than cure. Here's how to minimize the risk of mould in your swamp cooler:
1. Regular Cleaning and Maintenance
This is the most crucial step. Clean your evaporative air conditioner thoroughly at the end of each cooling season and before starting it up again. This involves:
- Cleaning the pads: Remove the pads and soak them in a solution of water and a mild detergent. Rinse thoroughly and allow them to dry completely before reinstalling. Consider using a dedicated evaporative cooler pad cleaner.
- Cleaning the water tray: Scrub the tray with a brush and soapy water, ensuring you remove all sediment and debris. Rinse and dry completely.
- Checking for leaks: Examine the unit for any leaks, as standing water provides an ideal breeding ground for mould. Repair any leaks promptly.
2. Using Clean Water
Use clean, fresh water to fill the unit. Avoid using stagnant or contaminated water.
3. Proper Ventilation
Ensure adequate ventilation in the room where the evaporative cooler is operating to prevent excessive humidity, which promotes mould growth.
4. Choosing the Right Location
Position your evaporative cooler in a location with good air circulation and away from areas prone to moisture build-up.
Remediating Existing Mould in Your Evaporative Air Conditioner
If you've already discovered mould, here's how to address it:
- Safety First: Wear protective gear, including gloves, a mask, and eye protection, when cleaning up mould. Mould spores can be harmful if inhaled.
- Thorough Cleaning: Follow the cleaning steps outlined in the prevention section, paying special attention to areas with visible mould. Use a suitable mould killer according to the product instructions. For stubborn mould, consider using a solution of bleach and water (always follow dilution instructions carefully). Never mix bleach with ammonia.
- Professional Help: If the mould infestation is extensive or you're uncomfortable cleaning it yourself, contact a professional cleaning service specializing in mould remediation.
Maintaining a Mould-Free Evaporative Air Conditioner: A Summary
By implementing these preventative measures and addressing any existing mould promptly, you can enjoy the benefits of your evaporative air conditioner while minimizing the health risks associated with mould growth. Regular maintenance is key to a healthy and efficient cooling system. Remember that early detection and prompt action are crucial in preventing a larger, more difficult-to-manage problem.
