TikTok Warns To Avoid This Mistake When DIYing A Mini-Split Installation

Ductless mini-split systems can be a great alternative to central HVAC systems. These systems are more energy-efficient than regular HVAC systems. They cool and heat in different rooms or zones, which gives you more control over how you cool or heat your home. However, mini-splits can be expensive. The average cost of a mini-split system installation starts at $4,000 but can be as high as $12,000. The more zones that you have in your house, the more installation will cost. One way to save a significant amount of money on a mini-split system is to opt for a DIY installation.

Many mini-split systems are relatively easy to DIY and most come with a kit and instructions to help with self-installation. Another thing that can help is knowing what to avoid if you decide to DIY a mini-split. TikTok user @lrn2d.us opted to do a full DIY mini-split installation. A year after installation, he shared his top mini-split DIY regrets with his followers. One of his biggest regrets is that he didn't get outside line covers, which are pretty easy to install.

If you don't have line covers, then the mini-split line set will just be left hanging on the outside wall of your home. In his video, @lrn2d.us made it clear that he considers line covers a must when DIYing a mini-split system. He mentioned that line covers are pretty affordable and he regrets not spending the money on them. Indeed, we found a 16-foot kit on Amazon for $70. But, in his video, @lrn2d.us stated that he saw a kit on Amazon for $40. There are many line cover kits available; you'll want to get one that is compatible with your particular mini-split. Make sure it is long enough for your particular system.

The TikToker also pointed out that a lack of line covers can look sloppy. Line covers make a DIY mini-split installation look professional, which Amazon reviewers also pointed out. Line covers can also be painted to match the exterior of your house, which looks nice. Another reason why @lrn2d.us feels that line covers are essential is they can prevent sun damage. Over time, the blistering summer sun can damage the lines, causing weathering, fading and cracking. Line covers should prevent this from happening. Lines can also be damaged by animals and other things. Line covers are durable and help to guard against this. Another advantage of line covers is that they help improve energy efficiency. Lines that are covered retain heat better, which makes them more energy efficient.
