7 easy steps to clean your mini-split
If your home is equipped with a mini-split system, its maintenance is crucial for optimal performance and air quality. The indoor unit, specifically the system's air filter, is one of the key components you should focus on caring for. Regular cleaning of the air filter not only contributes to the efficiency and longevity of the unit, but also helps to create healthier indoor air. In this publication, we will show you how to clean the filters of a mini-split system yourself.
Should I clean the mini-split filters or change them?
Most traditional HVAC systems use disposable filters. In contrast, most ductless mini-split systems have reusable filters that need to be cleaned rather than replaced. The frequency of cleaning your mini-split system's air filter depends on how you use it and the environmental conditions.
Manufacturers and service organizations recommend monthly inspections and additional cleaning as needed. However, more frequent checks may be necessary in polluted areas or if the unit is used continuously.
How do I clean the filter of a mini-split?
-
Before you begin, make sure the mini-split system is turned off. This will ensure your safety and the effectiveness of the cleaning process.
-
After reading the manual, locate the air filter behind the front panel of the indoor unit.
-
Remove the air filter by pulling it out of the housing. While some models will slide out intuitively, others may require you to unplug or unscrew the filter.
-
Inspect the filter carefully for visible dust, dirt, or debris. If dirty, replace the disposable filter.
-
To clean a dirty reusable filter, rinse under warm water and use a mild detergent if necessary. Allow the filter to dry completely before replacing it.
-
When the filter is dry and clean, replace it securely back into the housing.
-
Finally, turn on your mini-split system and make sure there are no strange noises or problems operating.
Other DIY tips for Mini-Split system
While the HVAC air filter is an important component, there are other cleaning tasks that homeowners can do on their own to keep their indoor mini-split systems in good condition:
Draining system check
Another important aspect of mini-split system maintenance that you can do yourself is to check and clean the drain system. Its regular inspection and cleaning will prevent water accumulation and potential leaks, keeping your system running efficiently.
-
Consider your own safety. Before beginning any work, make sure the mini-split system is turned off.
-
Locate the drain line connected to the indoor unit. Check for any visible signs of blockage or debris.
-
As with the filter, use a mixture of warm water and mild detergent to clean a clogged line. For more stubborn blockages, use a pipe brush or a wet/dry vacuum with a fine nozzle.
Neat and tidy appearance
Regular cleaning of the surfaces not only maintains the appearance of your mini-split, but also prevents dust from entering the internal components. To prevent dust and dirt from accumulating on the surface of the unit, periodically wipe the exterior of the indoor unit with a soft, damp cloth for a few minutes. Wipe gently to avoid scratching or damaging the exterior coating. A clean appearance contributes to optimal performance and extends the life of your ductless mini split system.
