How to Cover a Mini Split: A Comprehensive DIY Guide

When it comes to mini-split air conditioning systems, the outdoor unit and the connecting line set can often be an eyesore, disrupting the aesthetic of your outdoor space. However, with a little creativity and the right approach, you can effectively cover and conceal these components, enhancing the overall appearance of your home. In this comprehensive guide, we’ll explore various techniques and strategies to help you cover your mini-split system seamlessly.

Measure and Prepare the Line Set

Before you begin, it’s crucial to accurately measure the length and diameter of your mini-split’s line set. This information will ensure that you select the appropriate line set cover or wrap that fits your system perfectly. Measure the length of the line set from the outdoor unit to the indoor unit, and note the diameter of the individual lines. This data will be essential when choosing the right cover or wrap.

Once you have the necessary measurements, you can select from a variety of line set covers or wraps designed specifically for mini-split systems. These covers come in various materials, such as PVC, aluminum, or decorative fabric, and can be easily installed and removed for future servicing.

When selecting a line set cover, consider the following factors:

  1. Material: Choose a weather-resistant material that can withstand the elements, such as UV exposure and moisture.
  2. Insulation: Look for covers that incorporate insulation to prevent condensation and maintain the efficiency of your mini-split system.
  3. Flexibility: Opt for a cover that is flexible and easy to install, allowing you to navigate around corners and bends in the line set.
  4. Aesthetics: Select a cover that complements the overall design of your home and outdoor space.

Install the Line Set Cover or Wrap

Carefully follow the manufacturer’s instructions when installing the line set cover or wrap. This typically involves securing the cover to the wall or ground using screws or adhesive, and then wrapping the line set within the cover. Ensure that the cover is properly sealed to prevent any air leaks or moisture intrusion.

Conceal the Outdoor Unit

For the outdoor unit, you can consider building a fence or enclosure around it to create a natural backdrop. This can be done using decorative screens, trellis panels, or even tall bushes and climbing plants. When constructing the enclosure, make sure to leave adequate ventilation gaps to ensure proper airflow and accessibility for future servicing.

Hide the Indoor Unit

When it comes to the indoor unit, you can explore various options to conceal it seamlessly. One approach is to paint the unit to match the wall color or wallpaper, blending it into the surrounding decor. Alternatively, you can create a built-in bookshelf or cabinet around the unit, effectively hiding it from view.

Another effective solution is to use hanging plants or artificial foliage to camouflage the indoor unit and its connecting cables. This not only adds a touch of greenery to the space but also helps to conceal the visual clutter.

Maintain Airflow and Accessibility

Regardless of the method you choose to cover or conceal your mini-split system, it’s crucial to ensure that the airflow and accessibility for servicing are not compromised. Make sure that any enclosures or coverings allow for adequate air circulation around the units, and that technicians can easily access the components for maintenance and repairs.


Covering a mini-split system can be a practical and aesthetically pleasing solution to enhance the overall appearance of your home. By following the techniques and strategies outlined in this comprehensive guide, you can effectively conceal the outdoor unit, line set, and indoor unit, while ensuring the continued efficient operation and accessibility of your mini-split system. Remember to measure, choose the right materials, and prioritize airflow and servicing needs to achieve the best results.
