5 Worst Mini Split Brands to Avoid

Based on customer reviews and personal experience, the worst mini split brands to avoid are MRCOOL, LG, Carrier, Midea, and Kilmaire.

These brands offer mediocre product quality, low energy efficiency, and subpar customer service.


Are you considering an MRCOOL mini split system for your home or office? You may want to think twice.

Despite their low prices and catchy name, MRCOOL has a reputation for being one of the worst mini split brands on the market.

One of the main issues is mediocre product quality, leading to freezing and leaking over time.

To make matters worse, their customer service could be more responsive in responding to user queries.

It’s no wonder why several HVAC companies and new customers avoid this mini split brand altogether.

2. LG

This might be a shock to many seeing LG in our mini split brands to avoid list, but I have my reasons.

I made the mistake of purchasing an LG mini split AC system, and I regret it. From the get-go, I noticed the system wasn’t performing as well as I had hoped.

The cooling was weak, and the air quality was like that of the worst air purifier. But what really made me regret my decision was when the system broke down only a year after installation.

On top of that, their mini splits are less energy efficient compared to Japanese mini split brands.

But the issues with LG mini split systems don’t stop there.

Many customers have reported issues with the installation process, with some claiming that the systems were installed incorrectly, leading to further problems.

Carrier is a brand that has been around for decades, and they’re known for making some of the top heating and cooling systems on the market.

However, when it comes to mini splits, Carrier is a brand that you may want to avoid.

If you’re looking for a mini split system that is reliable and efficient, you won’t find it with Carrier. In fact, they are among the bad mini split brands to avoid.

This brand is known for producing low-quality mini splits prone to breakdowns and malfunctions.

Many customers have reported that their Carrier mini split systems have failed within just a few months of use.

Another issue with Carrier mini splits is their low energy efficiency. If you want to save on your energy bill, you won’t get much help from a Carrier mini split.

These systems are notorious for using more energy than their competitors, meaning you’ll end up paying more in the long run.

4. Midea

My friend bought a Midea mini split system for his house, and it’s been a complete nightmare.

The system constantly breaks down and needs repairs, which has been incredibly frustrating for him.

On top of that, the energy efficiency of the Midea mini split is terrible, and he’s noticed a significant increase in his monthly energy bills since he installed it.

To make matters worse, their customer support is practically non-existent, and my friend has had a hard time getting their help when he needs it.

Based on his experience, I recommend avoiding Midea mini splits if you’re in the market for a new heating and cooling system.
