Let's get into detail about each brand and what it offers, but first, let’s ask: Why ditch the ducts?


When Willis Haviland Carrier invented the modern air conditioning system, he gave mankind one of its biggest leaps in the mastery of nature — the ability to control the indoor temperature. A century later, the billion-dollar industry that he spawned continues to evolve — changing the way we experience temperature comfort. 

Today, temperature comfort is not just about having a system that can make you warm or cool; it remains about control, just as Carrier has drawn and envisaged. As climate changes and people’s lifestyles and habits evolve, the need for complete control over comfort has become more important than ever — and just as daunting.

Despite the many advancements in HVAC technology, there remains new comfort challenges. Unfortunately, these are the challenges that most conventional cooling and heating solutions can’t easily confront or tackle. Here’s a short list of some of the most common issues experienced with traditional HVAC systems:

  • Temperature inconsistencies
  • Inefficient use of energy
  • Noisy operation
  • Poor air quality
  • Inability to eliminate humidity
  • Inflexibility of the system
  • Complex installation procedures
  • Not being eco-friendly
  • Costly maintenance requirements
  • Weak system performance

In other words, the traditional AC systems, despite the recent HVAC advancements, leave much to be desired, taking away the most fundamental benefit that a modern air conditioning system is supposed to be providing — complete control over comfort at a lesser cost, lower energy-consumption, and higher money-savings.

And as comfort, cost, and energy-efficiencies become the primary requirements, real control over temperature means control over the things that really matter — control over the exact temperature that you need; control over the amount of energy that you consume; and control over the money-savings that you wish to earn. Unfortunately, no traditional system, despite its many advantages, is really living up to the billing.

“Where Traditional AC Systems Fail, a Mini Split System Delivers”

Amidst these new demands in air conditioners, a relatively new technology has emerged — ductless mini split systems. Where many types of traditional AC systems fail, a ductless mini split solution effectively delivers.

Not only are ductless AC systems superior to traditional HVAC systems when it comes to temperature control, efficiency, and overall performance, but they’re also better than your typical window units for many of the same reasons and more. While your average window air conditioners are lightweight and DIY-friendly, they come with some major downsides. They’re noisy and bulky and introduce security issues that you simply won’t get with a ductless mini split option.


As a system, ductless mini split is not new. Ductless mini split systems have long been popularly used in Europe and Asia, but they only recently gained their popularity in the United States. A ductless mini split system is a type of compact air-conditioning system that doesn’t require ductwork and which consists of an outdoor compressor unit and an indoor evaporator unit, the air handler.

Aside from the electrical wire, a ductless mini split has a piping system that’s passed through a small hole in the wall, connecting the indoor unit and the outdoor unit. This pipe system is composed of two copper tubes called a suction line and a liquid line, which are collectively called the line set. Specifically, these pipes are also called the refrigerant line because they transport the liquid substance called refrigerant throughout the system. 

This refrigerant constantly changes state and follows a cyclic process. It is the one responsible for absorbing and releasing heat that is essential in the cooling and heating, which is primarily the function of a mini split system. In other words, you can use a mini split unit either as an air conditioning system or a heat pump solution.

Another thing to note about the ductless mini split system is that they don’t just function as air conditioners. In some cases, they also serve as heaters, which makes them quite appealing for consumers who want a single unit to keep the thermostat at the ideal temperature year-round. This can also be an appealing upgrade for homeowners who have a gas furnace and want to take advantage of some electrically generated heat throughout the chillier months.

If you’re interested in a mini split installation with a heater, be sure to choose an option with a mini split heat pump. All of the brands we cover in detail below offer mini split systems with built-in heat pumps, which means they have the capability to both cool and heat your home. Make sure you’re choosing a model with this option if and reference the unit’s heating seasonal performance factor (HSPF) to determine which model has the most efficient heat pump.

As a System, What Makes a Ductless Mini Split Unique?

Ductless mini split systems offer the kind of powerful performance, efficiency, and versatility that you would normally find lacking in other systems, whether it’s a window-type unit or a central air conditioning system. Their high-degree of energy-saving capabilities and features, coupled with their structural and operational flexibility to any cooling or heating applications, make ductless systems the best alternative to traditional systems.

So, besides all of these great advantages, why would someone opt for a ductless system over central air? Homeowners who live in old homes that were not built with ductwork find that these systems provide impressive performance without having to rip up walls and ceilings. And, for modern dwellers, there is arguably no home improvement project that will help boost the salability of a home quite as much. In other words, if you’re looking for a great way to boost home value, a ductless mini split system is probably a wise investment.


To help you ditch the ducts the right way, check out the strengths of these top mini split AC brands:

GREE Ductless Air Conditioner Review

gree ductless mini split

Arguably, no other brand has dominated the HVAC market more than Gree in recent years. A veritable industry leader, Gree is the largest HVAC manufacturer in the world today and, as of 2019, the Gree Brand ranks 4th in overall market-share in the U.S.

Gree mini split products are characteristically among the most advanced, energy-efficient, and innovative that you can get your hands on in any HVAC market. As a brand, there’s not so much name-recall about Gree, but here’s an interesting fact: One of every three air conditioners in the world is produced by this company. 

In fact, in the last 20 years, many of the top AC brands that you are more familiar with get their technology and system from Gree. You can name a respected brand by random, for example, and there’s a good chance that some of their AC models are built by Gree. When it comes to mini split systems, Gree has some of the best product lines.

But if you’re looking for a particular Gree mini split system that fits your home and specific requirements, you can check out Sapphire, Vireo+, and Livo+ models. Many of these systems are Energy Star rated and boast of exceptional SEER rating of up to 39.5. Each of these models are also super-efficient, highly advanced, built with an ozone-friendly refrigerant called R410A, and powered by the energy-saving G10 inverter technology.

If cost is a concern, take note that Gree models are comparatively less expensive than other brands, yet they have comparable (or superior) high-efficiency refrigeration, airflow, and control systems, which are the right elements to have in an AC unit. In fact, most Gree mini splits are so advanced that they have been integrated with smart features and intelligent control capabilities. Just imagine an air conditioner that you can remotely control and manage through your smartphone, and you’ll get the idea.

Official sources state that a Gree model can help you reduce up to 65% of your energy consumption, without any impact on performance. Thus, for maximum comfort and savings, any Gree mini split unit will certainly be worth your expense. As for warranties, current Gree models are offered a five-year parts and compressor warranty.  This includes a FULL Unit Replacement with confirmed failure of a major refrigeration component.  Also, there is a one-year warranty on the remote. When compared with other warranty offerings from other brands, this one from Gree could be said to be one of the most comprehensive.

For a mini split option, Gree models are no doubt among the best choices.  ComfortUp is the largest online reseller of Gree Ductless Systems: we have the most stocked inventory, warehouse locations all over the U.S. and can offer the best pricing.  These are just some of the reasons why, here at ComfortUp, Gree mini split solutions are among our most excellent offerings. But, of course, you can’t just take our word for it, so here’s some of what our happy customers say:

We purchased this unit to cool our 400 square-foot garage. The installation was simple and this unit more than handles the load. It’s amazing how quiet both the interior and exterior units are. In fact, it is so quiet that you will have to look and find out if they are really powered on or not. We are very happy with the purchase.
James M.

This is one of the best investments we ever had! The cooling is incredible. It’s even felt throughout the living area of about 800 square feet, where before with the swamp cooler would have very cold areas and hot areas. It makes the house feel clean as well and all of our allergies have improved greatly. The outdoor unit is super quiet that even when standing next to it — all that we can hear is the noise from our neighbor’s air conditioning units.
David F.

I installed this in my bedroom and it cools and heats quickly. It helps offset the performance of the unit in the living room, which is not a GREE and does not work very well. I just got another 12,000 for the other bedroom, and it was on sale and I was able to save a lot. The guys at ComfortUp are great to deal with.
Steven V.

I have had this unit installed for two months now. Luckily, it was during the transition from winter to spring so I have been able to experience both cooling and heating. It does both very well and I could not be happier. I have it in my basement, which has a 7-inch drop ceiling and five rooms, which include the 24x26 main room, 8x13 workout room, 8x12 bathroom and two closets. I bought this unit oversized for the space because I also have an unfinished room and I’m planning to keep its door always open to allow it to cool also. This is a great buy!

Compared with other top brands, Panasonic is not far behind. In fact, Panasonic mini split systems are also among the most advanced and highly efficient units that are currently in the market. When shopping for your mini split solution, take time to check out the different Panasonic models. Being in one package, these systems are really easy to evaluate based on your specific needs.

Gree, Mitsubishi, LG, Panasonic Mini Splits: How Each One Stands Out

To help you decide which one suits best your needs and application, here are some additional insights on how the aforementioned systems stand out.


To effectively gauge the performance of mini split systems, it is important to look at how powerful they provide cooling and heating as a single system. In this context, Mitsubishi and Gree obviously have an edge due to their more advanced technologies, especially on heating capabilities. Take note that not all mini split systems, however advanced, can operate more effectively in a subzero climate. 

Mitsubishi, on the other hand, has a hyper-heat system that enables you to stay warm even during extreme weather. It’s capable of providing 100% heating capacity at between 0° F and 5° F outdoor ambient, and up to 85% heating performance down to -13° F outdoor ambient. The latest product launch from Gree, Sapphire, provides superior heating performance down to -22° F.  In terms of cooling performance, all four are at the same level.


In terms of energy-saving, all four brands are certified energy-savers, especially when compared with traditional systems. Despite the fact that these systems use advanced compressor technology, they have varying efficiencies. 

Compared with conventional systems, for example, Mitsubishi is 40% more efficient while Gree mini splits can lower your energy use by as much as 65%. 

LG ductless mini split units, on the other hand, offer their own degree of efficiency. Most LG systems have high SEER. Besides, they would not gain the ENERGY STAR® Most Efficient designation for nothing. 

With regard to Panasonic, their mini split efficiencies are also significantly higher than normal systems. With an exceptional maximum SEER of 31, Panasonic mini split systems are worth every consideration as well.  If Superior Efficiency tops your priority list, you can not beat Gree Sapphire


Mini split solutions are best-known for being built using advanced technologies. Technology and advanced systems engineering are often what separate mini splits from traditional systems. Powerful inverter and compressor technologies usually make up the backbone of these highly advanced systems. 

With Gree, you’ll get its excellent G10 inverter technology, on top of its other offerings like a condenser coil, intuitive sensing of indoor temperature, infrared-powered remote controllers, smartphone interface for remote access and control via smart mobile devices, smart operations modes, auto clean function, and even a self-diagnosis functionality. 

Mitsubishi, on the other hand, also provides an inverter-driven compressor technology, hot-start technology for quick heating, thermal-based indoor temperature sensing, smart, wireless remote controllers, and remote access through smart mobile devices as well. 

In terms of technology, Panasonic and LG are also advanced but it would be unfair to compare them with Gree and Mitsubishi because their systems are focused on certain strengths. Panasonic, for example, has an excellent ventilation system that is also customizable and can be integrated with sensors and LED light for maximum performance and efficiency. LG, on the other hand, has a really advanced set of control technologies that include both smart control systems and communication gateways, including specialty accessories.


Your mini split’s filtration capability determines how safe, clean, and healthy the indoor air is that you’re getting from your comfort system. The Environmental Protection Agency has determined that the air we breathe at home is in fact two to five times more polluted than the air we inhale outdoors. This one fact alone makes filtration an important consideration when choosing your next mini split system. 

Moreover, the quality of air filters will also have an impact on your comfort and total cost of ownership of the system. Ideally, air filters are required to be replaced at least every three to four months, but manufacturers usually provide a recommendation on how frequently you should replace them. 

With Gree, Mitsubishi, LG, and Panasonic mini split solutions, you would not have problem with air filters at all, nor the associated issues related to quality or cost of maintenance. 

Gree, for instance, provides a combination of some highly advanced air filters that include the photocatalytic, catechin, active carbon, and silver ion filters that can effectively eliminate bad odors and at least 99.9 % of organic air pollutants, bacteria, and other harmful airborne contaminants. 

Mitsubishi, on the other hand, boasts of washable air filters that are not only just as effective but can also last up to 10 years. 

LG, for its part, provides a plasma-based indoor air purifying system, which also offers an excellent air treatment technology. 

Panasonic, in addition to its high quality air filters that are designed to reduce moisture and airborne contaminants, provides helpful vent fan accessories for better air filtration, such as the WhisperGreen Select 50-80-110 CFM and the WhisperComfort Energy Recovery Ventilator (ERV). Take note that both help enhance indoor air by removing pollutants and preventing the development of mold and mildew. 

Overall, Gree, Mitsubishi, LG, and Panasonic mini splits look to be equal when it comes to providing better filtration for quality indoor air.

Warranties, Rebates, Tax Credits, and Other Incentives

The associated warranties, as well as incentive programs and rebates do not only make your new AC more attractive but also serve as a great way to maximize all the possible savings that come with the purchase. Remember that the higher the efficiency of the system, the more incentives and rebates are usually offered. These incentive programs are initiated to encourage homeowners to choose more efficient systems that are less energy-hog and less harmful to the environment.

As far as warranties go, it's important to note that EVERY manufacturer requires that the mini split system be installed by a state-licensed HVAC contractor in order to be eligible for warranty.  If you were to have a warranty concern, you will have to provide proof of proper installation before a Tech Support Team will provide warranty assistance. It's also important to remember that EACH brand's warranty only covers parts and does not include any concession to cover labor or troubleshooting expenses.  

Many brands and specific systems qualify for various tax credits, incentives, and rebates at different levels — federal, state, or local level.  Available rebates are always changing and differ based on your geography, so it's best to check with your local agencies or use this ZIP CODE Rebate Finder provided by Energy Star.

It’s Not Universal

The truth is, mini splits from Gree, Mitsubishi, Panasonic, and LG are alike and different in so many ways. It’s always a difficult task comparing all these excellent systems, given their specific qualities and advantages, but if you really have to choose, don’t forget to consider your specific need and situation. 

Mini splits are great systems, but getting the best deal out of it is not always about getting what’s the most technologically advanced, what has the highest SEER, or what offers the best components. Everything still always boils down to what suits your exact need and budget.

So, when you’re out shopping for your mini split system, don’t forget to compare the systems, but compare wisely — based on what can give you the best comfort and convenience at a lesser cost, or what can save you money both in the short-term and the long-term without compromising your comfort.
