Mini-split brands to avoid


When it comes to mini-split brands, Mr. COOL has garnered mixed reviews that highlight some significant concerns.

One of the main issues is that Mr. COOL is not a manufacturer but a distributor, resulting in varying product quality from different companies.

Customers have reported problems with their air conditioning systems freezing and leaking over time, pointing to potential reliability issues.

Moreover, their after-sales service has left much to be desired, with many customers expressing frustration over the lack of assistance regarding maintenance and manufacturing issues.

This lack of support and guidance can be a significant drawback for consumers looking for reliable solutions for their heating and cooling needs.

As a result, many HVAC companies advise caution when considering Mr. COOL as a brand for your mini-split system, as the potential pitfalls seem to outweigh the benefits.


Carrier, one of the world’s leading HVAC brands, might seem like a popular choice for a mini-split system. However, many users have shown dissatisfaction with their Carrier mini-split units.

One of the major complaints is the loud noise generated by these systems during operation, leading to noise pollution and disrupting the tranquility of the living space.

Additionally, customers have reported issues with the coil, which began leaking after just a few years of use.

This not only causes inconvenience but can also result in increased AC maintenance and replacement costs, as some reported spending significant amounts each year on upkeep that was not covered by the company’s warranty.

The lack of a permanent fix for the air conditioning units has left many consumers frustrated and disappointed with the brand’s reliability.

If you’re looking for a dependable and efficient heating and cooling solution, you may want to think twice before considering a Carrier mini-split system for your home.

LG is one of the world’s leading technology brands, offering a wide range of products across the globe.

However, regarding mini-split systems, LG is one of the worst mini split brands to consider. Many prefer reliable Japanese brands over LG due to their lower rate of faults and better long-term efficiency.

LG mini split units have garnered a reputation for cooling issues, with some systems stopping cooling altogether or exhibiting erratic behavior, such as turning off and on by themselves.

Moreover, some customers have encountered problems with the coil, which can lead to expensive air conditioner repairs that can cost hundreds of dollars each year. Beyond these technical issues, many users have faced challenges with the installation process.

Some have complained about unclear instructions, making setting up the units challenging to install.

Another central point of contention is LG’s poor customer service, which has dissatisfied many customers. Long wait times and unhelpful responses have added to the frustration of those dealing with faulty LG mini-split systems.

For homeowners seeking a dependable cooling and heating solution, turning to reliable Japanese brands may be a wiser choice, as LG’s mini-split offerings have proven to be less reliable and efficient, leaving consumers disappointed and regretful of their purchase decisions.


Kilmaire is an American brand with a presence in over 70 countries across the world. However, many users have expressed dissatisfaction with this brand, particularly their mini-split products.

Numerous customers have reported problems with the circuit board, leading to system functionality issues. Additionally, a common complaint is the loud noise that some mini-splits emit, causing discomfort and annoyance for homeowners.

After a few years of usage, customers have faced a wide range of problems with no warranty coverage, leaving them to replace various parts on there own, incurring additional costs.

Furthermore, the customer service provided by Kilmaire has been negligent, with many customers reporting receiving little to no help from the customer service department.

The reported problems with circuit boards, noise, after-sales service issues, and the need for more energy efficiency have made Kilmaire mini splits less desirable for consumers looking to invest in a dependable and energy-saving air conditioner system.

Midea is a Chinese brand that has gained a reputation for its technological products, and its mini-split systems have become widely used in Asia and beyond.

While considered an efficient solution, some customers have encountered issues with Midea mini-split after years of use.

One common problem users report is the occurrence of low levels of refrigerant, leading to leaks in hard-to-reach areas that require intervention from HVAC professionals.

Customers have also faced various other problems, including frozen evaporating coils, contaminated capacitor coils, fan malfunctions, and thermostat problems.

These issues have caused inconvenience and frustration for homeowners relying on Midea mini splits for their heating and cooling needs.

When consumers order their air conditioners, they may find that some essential components, such as the remote control or installation gear, are missing from the unit upon delivery.

The help from customer service has also been criticized for needing to be more responsive and helpful, making it challenging for customers to get the assistance they need.

Moreover, some users have found that the cooling power of the unit falls short of the advertised claims, leaving them uncomfortable in hot summer temperatures.

What to Look For In A Good Mini-Split System

When choosing a mini-split brand, several factors contribute to determining whether it fits your needs. Here are some key considerations to keep in mind:

  1. SEER (Seasonal Energy Efficiency Ratio): Look for brands offering higher-rated mini-split systems. Higher SEER ratings indicate better energy efficiency, which can lead to energy savings over time.
  2. Lifespan: Consider the expected lifetime of the unit. Brands that manufacture durable and reliable systems can provide better long-term value.
  3. Warranty: Check the warranty coverage for the mini split system. A comprehensive warranty can offer peace of mind and protection against unexpected repairs or replacements.
  4. Price: Compare the pricing of different companies.
  5. Customer Service: Look for brands prioritizing customer support and providing timely assistance when needed.
  6. Energy-Efficient Features: Consider brands incorporating advanced technologies. These features in the AC systems provide for more environmentally friendliness and can reduce utility bills.
  7. Heat Pump Capability: Check whether the mini split unit’s can cool or heat. Dual functionality can make the system more versatile and practical for year-round use.
