Developed in the 1970s, a ductless mini split system, as a spot cooling solution, has evolved in so many ways, but it is a system with so much groundbreaking potentials that it remains one of the very few highly significant innovations in air conditioning technology. Today it continues to create huge impact in the way air conditioners are developed. With air conditioners widely attributed as one of the technologies with the biggest environmental impact, ductless mini split impresses as the “new thing,” staying aligned with the evolving needs and changing lifestyle and, not surprisingly, emerging as one of the core examples of “better systems” that seem to break limitations posed by many unique AC applications and challenges. It is within this backdrop—in effective tackling of air conditioning constraints—that Gree, one of the industry leaders in air conditioning technologies sits atop as authority, innovating and producing some of the best ductless mini splits ever made available in the HVAC market today. To help you on your next ductless mini split purchase, we'll be comparing the different ductless models to give you an idea about their different capabilities, how they vary from each other, and how each one is designed unique as an individual system. But first, let's take a glimpse of these different models.
State-of-the art-technology but also manufactured using expansive vertical integration and the highest levels of testing and innovations. As demands for more powerful, energy-efficient, environment-friendly, and highly flexible comfort AC systems start to define the development of cooling and heating technologies, Gree ductless units certainly stand at the helm, offering superior capabilities and functions for maximum comfort experience. To understand how excellent Gree mini split systems are, it is important to take at their biggest strengths. Take note that all Gree mini splits are available in different models, which include the Crown, Terra, Neo, Vireo, Rio, and Livo series. These units come in different capabilities. Essentially, though, they share some common features, which include the following:

You are free to mix and match the air handlers with any type of compressor, depending on your preference. Gree mini split indoor units are available in the following designs: high-wall unit, universal floor and ceiling unit, ceiling cassette, slim-concealed duct, and mini-floor console.
Energy Efficiency Ratings
As an initiative to conserve energy, lower greenhouse gas emissions, and curve energy costs, most governments make it mandatory for manufacturers to follow the minimum efficiency or performance standard for all energy-using equipment and appliances that they produce. In the United States, the Department of Energy (DOE) regulates and sets these efficiency standards. For air conditioners, the most significant energy-efficiency ratings to look at are the Seasonal energy efficiency ratio (SEER) and the Energy efficiency ratio (EER). For the heat pumps, the most important energy-efficiency ratings that you should be mindful about are the Heating Seasonal Performance Factor (HSPF) and Coefficient of Performance (COP). Due to the fact that ductless mini split systems can function both as a cooling and heating solution, these four energy-efficiency ratings are worth the attention if you want to properly compare the different mini split options. Now, before we go into the details about the energy-efficiency ratings of Gree mini splits, it is important for you to have a general idea what these ratings are about and what are the current minimum energy-efficiency ratings for air conditioners. Take note that the efficiency ratings of air conditioners help determine the performance of the system. So, let’s start first with the definition and proceed comparing the SEER, EER, and HSPF of the different Gree mini split models.
Specifically, SEER pertains to the efficiency or performance of a unit in relation to the amount of energy that it consumes in a specific period. Technically, SEER is the cooling output (in British thermal units or Btu) of a unit in a given period or season divided into your total energy usage in watt hours that was consumed in the same period or season. The quotient is the efficiency rating of your unit. Here’s how it looks like: Cooling output ÷ Total energy consumption in a given period = SEER rating. To give you a better idea, let’s say there are two units that were used simultaneously during the whole Summer period. The model that consumed lesser amount of energy has usually the highest SEER and considered the more efficient. In a nutshell, the higher the SEER, the more energy-efficient the unit is. Currently, the DOE sets 14 SEER as the minimum standard rating in the Southeast region and Southwest region of the United States, which is understandable because these areas are characteristically have a hot-humid and hot-dry weather. In the northern parts of the country, the minimum SEER is 13. What this variation shows is simple—that the minimum standard SEER is set based on consideration to the climate differences among the regions. As a side note, the minimum standard SEER for all areas in the US might again be adjusted after a consensus agreement was reached for the updated energy efficiency standards. By 2023, the Northern region will be mandated with a 14 SEER for units under or over 45,000 Btu/hr. In the Southern region, it will be 15 SEER for units under 45,000 Btu/hr and 14.5 SEER for those over 45,000 Btu/hr.
SEER of the Gree Mini Split Models
When it comes to SEER, the newest Gree mini split model Sapphire now rules, boasting of up to 41 SEER. Coming in close second is the long-time Gree mini split royalties, the Crown and Crown+, which although dethroned by Sapphire in this aspect, remains a jewel of a system, thanks to their 30.5 SEER. At their heels are Terra with 27 SEER, Vireo+ with 23 SEER, and Neo with 22 SEER. The Gree models with the lowest SEER are Rio and Livo+ with 16 SEER. Compared with other traditional systems (and even with other mini split brands), however, the last two models are not in any way the least when it comes to efficiency, especially when you consider the fact that the current highest minimum standard SEER is pegged at 14. And remember that the average SEER of most modern residential ACs ranges from 13-16, although you can also find systems with a 17 SEER. Now, obviously it’s no brainer to determine what’s the most efficient models when you compare a Gree model with 41 or 30.5 SEER with some traditional systems with 17 SEER. At the very least, we can fairly compare Rio or Livo+ with a 16 SEER with say, another model with 17 SEER. Strictly speaking, the model with a 17 SEER is of course better in terms of energy-efficiency. But a 1 SEER difference is not going to tell the whole story. In fact, it would not even matter at all when what you’re comparing is a highly advanced, state-of-the-art technology like Gree Rio or Livo+, with a traditional system built with 17 SEER but lesser quality in terms of components, features, and energy-saving capabilities. The choice is starkingly obvious—you’d be better off when you choose Gree.
Energy Efficiency Ratio (EER) is another way to measure the efficiency of an air conditioning system. Unlike SEER, which is limited to the usage of the unit within a specific season, EER tells you how the system efficiently operates using a specific amount of energy. In computing the EER, the cooling output of a particular unit (expressed in British thermal units or Btu) is divided by the amount of energy use (in watt hours). The ratio derived is the EER of the system. To help you get a better grasp of this idea, let’s use Crown+ as an example. This particular model has the highest capacity of 18,000 Btu. Let’s say you bought this model and in one instance it consumed 1200 watts of electricity. To find the EER, you do the following calculation: 18,000 Btu/1200 watts = 15 EER. Just like with SEER, the higher the EER means the more the system is energy-efficient. With Gree Crown mini splits, Sapphire with 16.7 EER comes with the highest. It is followed by Crown+ with 15.8 EER. Ranked next as the third and fourth best are the Terra and Neo models with close values at 14.5 EER and 14.2 EER respectively. Coming in next is Vireo+ with 14 EER and then followed by the Rio model with 12.0 EER. The Gree models with the lowest EER among the product lines is the Livo+, which has 10.55 EER, a rating that is still very high when compared with other models of different brands.
Heating Seasonal Performance Factor (HSPF) of a system refers its total heating efficiency for a specific season. Just as SEER determines the efficiency of an air conditioning system for a specific cooling season, HSPF is used to determine the efficiency of a heat pump for a specific heating season. Since ductless mini splits can work both as an air conditioner and as a heat pump, determining the HSPF of Gree mini splits is just as important as finding out their SEER. Technically, HSPF is the ratio derived when you divide the total heating output (expressed in Btu) of a unit with the total energy used during a specific season. To further explain, let’s use a Gree mini split model as an example. Let’s say you purchased a Sapphire unit with a rated capacity of 18000. After using it over the whole winter season, you’ve determined that it consumed 1200 W. By dividing the total heating output with the total energy consumed, you get 15 HSPF. Now, let’s say your current heat pump at home has a rated capacity of 36,600 with 8 HSPF. This unit can cost you 4575 W during the whole heating season. Now, for example you replaced it with a Gree Neo ductless heat pump with the same rated capacity of 36,600 but with a 10.0 HSPF, your energy consumption on the same heating period will just be 3660. Gree mini split systems have different HSPF capabilities. Again, the newest model Sapphire emerges as the most efficient with up to 15 HSPF. The Crown+ and Vireo+ models come second with up to 10.5 HSPF. It is followed by Neo with 10.0 HSPF, and then by Terra with 9.8 HSPF. Rio and Livo+ have 9.5 HSPF and 9.0 HSPF respectively. Take note that the higher the HSPF, the more efficient the heat pump solution is.
When buying an air conditioner, one thing that you should consider is the size or tonnage, which usually refers to the system’s cooling and heating capacities. When it comes to air conditioners, size is not about dimensions. The size of ACs is measured based in “tons,” which refers to the amount of heat (measured in British Thermal Units or BTUs) that an air conditioner can eliminate in a particular space in hour. As a standard, one ton is equal to 12,000 BTUs per hour. This means that if you have a one-ton air conditioner, it can eliminate an amount of heat that is equal to 12,000 BTUs. If you have a two-ton AC, it can remove a double amount of heat that is equal to 24,000 Btu per hour. We can go on and on or you can do the computation yourself, but you get the idea. Basically, the more ton of a system, the bigger its Btu, and vice versa. Now, here’s a word of caution: when it comes to air conditioners, bigger doesn’t always mean better. Keep in mind that one size doesn’t fit all. The problem comes when people use big-sized ACs for smaller space, or use small-sized AC for a bigger space. Obviously, oversized and undersized air conditioners are bad to have. So, when you’re looking for the next AC for your home, choose the right size for your space. Your HVAC contractor can help you on this matter if you’re not sure what size to look for. Gree mini split models vary in rated heating and cooling capacities. Generally, though, we can say that Gree Neo, Vireo+, and Livo+ provide more size options, with up to 36,000 Btu. The Terra and Rio models come next with up to 24,000 Btu. Being the newest systems, Sapphire and Crown+ are for now only available up to 18,000 Btu.
Also functioning as heat pump systems, Gree mini splits have some of the best heating capabilities. What stand out most, however, are the Sapphire and Crown+ models, boasting of ultra-heating capabilities compared to the rest which are integrated with the standard heat pump system components.
Energy Star Rating
Except for Gree Rio and Livo+, all of the Gree mini split models Energy Star-labelled products. Energy Star rating is a government-backed labelling program that was developed to encourage manufacturers to produce more energy-efficient products like an air conditioner. The Energy Star label provides you the assurance that the system passed the EPA energy efficiency standards.
As part of its unique advantages, Gree mini splits are known for its smart features, which include Wi-Fi connectivity that allows you to connect the system to the internet and be able to manage and control the unit through any smart mobile device, such as a smartphone and tablet. Except for the Gree Neo and Gree, the rest of the Gree mini split models are Wi-Fi-enabled.
Gree mini splits vary in airflow designs and capabilities. Sapphire and Crown+ come with 4-way adjustable fan system, Rio, Neo, and Livo+ with vertical swing design, Terra features a 4-way swing fan system, and Vireo+ a bi-directional airflow capability.
Gree mini splits are also not built with the same type of air filters. Sapphire, Crown+, and Vireo+ models are all built with polymeric air filters while the Neo, Rio, and Livo+ models come with the standard air filters. Only the Terra model carries a photocatalytic filter.
Gree mini splits, except for the Rio model, are designed with the highly useful power-failure mode. This allows the system to return to its last operating mode when the power is back and the unit is turned on after a power outage or interruption.
Except for the Rio and Livo+ models, all the Gree mini splits are designed with anti-corrosion coating as added protection.
All Gree models come with attractive warranties. On the one hand, the Sapphire, Crown+, Vireo+, and Livo+ models are offered with a five (5) year warranty on parts and assured with full replacement. On the other hand, the Terra, Neo, and Rio models are available with a five (5) year warranty on parts and seven (7) year warranty on the compressor.
All of Gree mini splits operate quietly. While in operation, they actually produce a sound which is barely a whisper. The different models, however, have varying sound pressure. When it comes to indoor sound, Sapphire is the quietest, offering as low as 19 db(A). This is followed by Vireo and Livo+ with 26 db(A) and 28 db(A) respectively. Neo and Rio come with as low as 40 db (A), while Crown+ and Terra are available with 41 db (A) and 42 db (A) respectively. As for the outdoor pressure, the quietest are the Terra and Rio models, both coming as low as 49 db (A). Except for Neo that boasts of 50 db (A), the rest of the models have an outdoor pressure of as low as 53 db (A).
