While there are a lot of different HVAC companies out there, most of them producing multiple lines of mini split ACs, it can be hard to choose. If you are looking to install a mini split system or replace a central AC, you have your work cut out for you.
This article will examine the Gree mini split AC systems. We will cover buying considerations, installation concerns, and offer troubleshooting tips. The Gree mini split reviews will help you find the perfect model for you and your home. Read on to find out which one you should buy.
Gree Mini Split ACs Compared
Why Choose Gree?
For almost 30 years, the China-based company has expanded their home climate control options around the globe. Gree focuses on efficiency, as most companies do. Their mini split systems are even or above industry standards in SEER ratings, which is always something to look for.
They also have an incredible warranty for the system, provided you follow specific guidelines. However, you have options for installation and types that offer you the freedom to choose the best methods and still maintain a warranty. Not many other companies will offer that.
What to Look For When Buying a Gree Mini Split System
Before you head out and put your credit card on the counter for a new Gree mini split system, there are several things you should consider. Let’s break them all down here, so you know what to look for.
Gree has longevity and reputation behind them. Since 1991 they have produced some of the most reliable and efficient AC systems around. However, even being a global force, they aren’t a household name yet.
That is bound to change as more and more people learn to appreciate the technology and reliability they build into every unit. While some of their features may not compare to those of the bigger competitors, they aren’t that far off. Gree is definitely a brand you can rely on.
Heating and Cooling Capabilities
The space you need to heat and cool is the most significant factor in your decision-making process. To get the right size, you need to know the square footage of the room or rooms you are going to cool. The average measurement is to take the length multiplied by the width.
However, you have to consider other factors, too. Ceiling height is a big concern, as are windows that let in direct sunlight. If you are worried about humidity, the more furniture and clutter you have in a room, the harder and longer it is to dehumidify.
When considering running costs, you need to look at two main numbers. The SEER rating is the cooling efficiency of the unit, while the HSPF is the heating efficiency. Almost always, the mini split systems will be more efficient while cooling. Heating a space takes a lot of energy, which will lower efficiency.
On average, you want a minimum of 16 SEER and 8 HSPF. Gree has models that exceed 25 SEER and over 10 HSPF. When it is all broken down, Gree will cost you about 80 cents per day to run their system.
If you do this year-round, including heating, you can expect to pay an average of $24 in the summer and about $46 in the fall and winter months. Your annual total will be right around $225 to $275, depending on your cost per kWh.
Repair Parts, Costs & Warranty
One downfall to the systems is their replacement parts and warranty service. This doesn’t mean they are bad, but you will have to go through an authorized dealer while the unit is in warranty. Gree doesn’t have a US-based operation, so they rely on vetted vendors to do that portion for them.
If you just need a replacement part, you can find them easily through Amazon. However, if your unit is in the warranty period, doing the replacement yourself can void the rest of the warranty. The costs and labor, though, are slightly below the industry average, so even using the third-party vendors doesn’t set you back a whole lot compared to other brands.
The warranty is a bit tricky. If you have the unit purchased and installed by a Gree-approved vendor or dealer, the warranty is 10 years on all parts, labor, and compressor. However, this is only if you are the homeowner and live in the home, meaning you can’t get a 10-year warranty if you purchase and place in a rental unit you own. You also have 60 days to register.
If you purchase and have the unit installed at a residential property you don’t live in, the warranty drops to 5 years. If the property is commercial, the warranty drops to 1 year parts and 5 years compressor.
Regardless of which warranty you fall under, all remote and wireless control options have a 90-day warranty period.
Value for Money
Gree mini split systems have a fairly high value for the money. Not only are they designed to run efficiently for up to 10 years, but you will save a lot of money due to their dependability and reliability as well.
You get what you pay for, as the saying goes. With Gree, you will pay more upfront for their systems. However, the savings come in with better energy efficiency, which will end up saving you more money over time compared to the other brands.
5 Best Gree Mini Split ACs Reviewed
The best Gree mini split ACs reviewed and compared, give you a chance to find the ideal model that meets your needs. Below are the 5 best Gree mini split models to get you started.
1. Gree 12000 BTU Mini Split
The Gree Livo+ series offers you a lot of choices. Not only can you select the right BTU rating for the space, but you also get the ideal heating and cooling temperature range to go along with it.
The 12,000 BTU system is the most popular in this range. It offers you cooling and heating to rooms up to 650 square feet. Even in the winter, with temperatures dropping to below freezing, the heat pump will heat your home without the need for supplemental heat sources.
With a SEER rating of 16 across the board, you will spend a nation-wide average of about $1.05 per day on operating the unit. It is a single zone system designed to cool and heat a single room. However, depending on the BTU model you select, that room can be quite large.
If you have a small room (under 400 square feet), you may find it more practical to go with the 9000 BTU option. It maintains the SEER 16 rating and will cost less than a dollar per day to operate.
Likewise, you can also go larger if your space is bigger or requires extra power. Aside from the 650 square foot capacity 12,000 BTU model, you can also choose the 18,000 or 24,000 BTU options. These will cover areas up to 1000 square feet or 1300 square feet, respectively.
Finally, you have the largest option, the 30,000 BTU model. This Livo+ system will cool rooms up to 1650 square feet. The running costs will be a bit more, but the systems are designed to be as efficient as possible.
Each of the Livo+ models, regardless of capacity, uses the G10 Inverter with a variable speed heat pump. The G10 will power through any conditions and operate just fin at temperatures to 0 degrees (F).
All of the systems range in noise level between 52 and 65 dB, which is quiet enough to maintain a comfortable volume on the television or holding a conversation with the units operating at the highest fan speeds.
The Livo+ warranty is the same as all the others, which means if you have it installed by a Gree certified installer, you are worry-free for 10 years.
2. Gree Dual Zone Mini Split
If you are looking to heat and cool two rooms, then you want to learn more about the Gree dual-zone mini split system. The Vireo line uses the Multi21+ heat pump and inverter compressor to power up to 30,000 BTUs per box.
There is a wide range of options you can choose from as well. When it comes to dual-zone climate control, though, the most popular is the 12,000 & 24,000 BTU kit. This means you have one air handler that operates with a 12000 BTU capacity and a second one that uses 24000 BTUs.
The larger air handler would be ideal in a large living room or open living space with cooling capacity up to 1300 square feet. The 12000 BTU system will do well in the master bedroom cooling spaces up to 650 square feet.
Each unit in a dual-zone set up is individually controlled. With the system you will get the heat pump and compressor, two air handlers, their wiring, and refrigerant lines as well as two remote controls, one for each indoor unit.
The Vireo line is one of Gree’s most efficient, too. Each model has a SEER rating of 25, which means in a dual-zone setup, you are spending about $1.20 to run both air handlers every day.
The one downside is that they are also among the loudest produced by the company. It isn’t so loud you need to start yelling to hold a conversation in your house, but at 56 dB, you will notice when they are running.
The price is higher than the industry average, especially for the smaller combinations. Still, with a 10-year warranty and extreme efficiency, the systems will earn their keep and do their part to keep your energy costs low.
If you feel the 12k/24k model isn’t the right fit for you, there are other options. Each of them uses the same 30000 BTU capacity heat pump and Multi21+ Inverter compressor. The only difference will be the BTU capacities of the two air handlers.
Your options are a choice from the following:
- 9000 / 9000 BTUs
- 9000 / 12000 BTUs
- 9000 / 18000 BTUs
- 9000 / 24000 BTUs
- 12000 / 12000 BTUs
- 12000 / 18000 BTUs
- 12000 / 24000 BTUs
- 18000 / 18000 BTUs
- 1800 / 24000 BTUs
3. Gree 4 Zone Mini Split
When you want to control the temperature in every room of your home, the quad-zone system from Gree is your answer. This set up includes three air handlers with a 9000 BTU capacity and one with a 12000 BTU capacity.
All of this cooling power is handled by the quad-port Multi21+ G10 inverter and heat pump. Effective down to 0 degrees (F), you won’t have any problem using your new Gree quad-zone system to keep your home at the ideal temp.
One thing to note is that you will need to purchase three additional line sets, which aren’t included in the system but are required. The initial cost is also one of the highest you will find for a multi-zone system. However, throw in the Gree certified installation, and you have a full decade of worry-free heating and cooling in your home.
Not only that, but the 21 SEER unit will help lower your monthly energy bills by only costing you about $1.45 per day to operate. This, of course, depends on how many hours you run the system, how many zones are running, and your cost per kilowatt-hour.
The Vireo quad-zone mini split set isn’t the quietest of the bunch, which is the most complained about feature of the entire Gree product line. Producing about 56dBA of noise, you won’t be interrupted while watching television, but you may find it difficult to fall asleep to.
4. Gree Ceiling Cassette
Perhaps you are looking for the benefits of a mini split system, the power, and the performance of a Gree mini split, but you don’t want the bulky air handlers on the wall. The Gree mini split ceiling cassette system is your answer.
Instead of a decorative wall hung unit, ceiling cassettes look like any other embedded register. Their sleek design and automatic louvers provide coverage up to 1000 square feet.
With this multi-zone system, you can enjoy instant heat and timely cool air whenever you need them. The system can be hung in a drop ceiling, regular ceiling, or even on the floor. No ducting is needed as they still operate just like a standard mini split system, without the wall hung air handlers.
The same 10-year warranty is included when installed by a Gree HVAC technician, and you won’t have to worry about parts, service, or failures for at least a decade. You do need to purchase the two extra line kits, though, which adds to the initial price.
With a 21 SEER rating, though, your daily operational costs will be below a dollar, and you will see near-instant savings on your monthly energy bills. In some areas, these systems will also qualify for tax credits and energy bill bonuses. You will need to check with your electric company to find out.
5. Gree Trizone Mini Split (Discontinued)
If you are looking to cool and heat three zones, the Gree Neo line up is what you want. This system will hold up to three air handlers on a single heat pump without losing efficiency or cooling capacity. It may be difficult to purchase but speak with your local HVAC specialist to see if they locate one for you.
The Gree 30000 BTU mini split system is designed to cool medium-sized rooms with two air handlers at 9000 BTU and the third at 12000 BTU. Like the Vireo systems listed above, the smaller units are better used in bedrooms up to 450 square feet while the larger unit can easily cool and heat up to 650 square feet.
Like all other Gree models, the 10-year warranty is in effect as long as you are living in the home you purchase it for, and a Gree certified dealer installs it. The other option, of course, is to install it yourself or have a non-Gree professional handle the installation. You will lose 5 years on the warranty, though.
The Neo units utilize the G10 inverter technology to maintain a consistent 22 SEER, the highest SEER rating Gree offers. Running all three air handlers every day will cost you, on average, about $1.50 per day.
The initial cost, plus installation, make the Neo system one of the most expensive on the market. However, even with that as a negative mark, when you consider that the system can hold a fourth air handler that can be installed at a later date, it provides you an opportunity for expansion or growth.
The Neo models are slightly less noisy than the Vireo line, producing up to 54 dB of noise. Though, in regular mode and after initial start-up, the system tends to operate at a 51 or 52 dB level, making it noticeably quieter. This is beneficial for those that like to sleep with their AC on.
When fall and winter come around, you will enjoy heat to your preferred temperature setting, even when the outside temp drops below 13 degrees (F). When all is said and done, this highly efficient line up will keep you cozy, comfortable, and saving money every month.
How Does a Gree Mini Split Work?
Gree mini splits use various models and air delivery methods along with a variety of outdoor heat pump styles.
All of their units use inverter technology to help lower noise and eliminate the start and stop of conventional compressor motors.
The systems all come with a remote control for operation, such as this model for the Vireo line.
The heat pumps operate at around 56 dB, which is near silent for outdoor operation.
The Multi-21+ heat pump will connect to and run up to five different (or the same) interior air handler units, including the ceiling cassette and floor or ceiling mounted styles.
The interior units come in a variety of sizes and styles. You can choose the standard wall mount mini split system, or if you want to hide the units, there are ceiling cassette versions available as well. No matter which you choose, you will enjoy the cold air int eh summer and hot air in the winter. All without having to wait for the system to warm up or cool down like you do with a conventional AC.
Pros & Cons of Gree Air Conditioners
Every brand and product has its distinct advantages and disadvantages. Gree is no different. The decision becomes figuring out if the pros outweigh the cons.
- Gree has high SEER ratings across the board. You will find energy efficiency ranges from 16 SEER to over 21 SEER, which can end up saving you thousands per year on your energy bills.
- With a Gree system, you have options. Both their heat pumps and air handlers come in a variety of sizes and styles to mix and match or choose from for the best option for you.
- There is a Gree system for your space. No matter if you are trying to cool a single room, five rooms, or heat a large garage, Gree has an option that meets your needs.
- Gree has high-quality standards and can stand behind their products. On average, a Gree system will remain trouble-free for at least ten years.
- Using the Gree Wi-Fi Kit WSBEC02, you can use your smartphone or tablet to control your system from anywhere, at any time (Vireo+ and Livo+ systems only).
- The Gree warranty is one of the best in the industry, but you have a few hoops to jump through to get it. The unit not only has to be installed by a licensed HVAC technician, but that tech must also be on Gree’s approved vendor list.
- You have a higher up front cost versus most other brands. While the savings are there, and Gree is in it for the long-haul, you will pay more out of pocket to get the system up and running.
- Replacement parts (while in warranty) must come from authorized dealers and be installed by Gree approved technicians.
Gree vs. Other AC Brands
When it comes to comparing to other brands, Gree does stand up. Of course, some brands perform better in certain instances but fall short in others. The key is to find that happy medium where you get great value for your money without a lot of negatives.
Mitsubishi is one of the top performers when dealing with mini split air conditioners. They have high SEER values like Gree but at a much lower cost. Pioneer systems cost about the same for multi-zone systems, but don’t have the higher energy efficiency and are lacking some of the standard features you will find in a Gree model.
For a more apples to apples comparison, you want to look at MRCOOL. MRCOOL has simple installation and even produces a line specifically set up for DIY installs. Gree has better heat pumps that can perform to colder temperatures without supplement, but MRCOOL mini split systems are lower in initial costs.
You may also find Daikin to be a large competitor to Gree. Their systems are cheaper, and the warranties aren’t as good, but they work well and offer a lot of the same features. One thing to note is that Senville, the new-guy on the block, produces high-quality machines at an industry-average price point. Someone to keep an eye on for sure.
Helpful Tips for Gree Mini Split Installation
Gree mini split systems are designed to be installed by licensed and approved HVAC professionals. However, as long as you don’t mind cutting your warranty time between 50 and 90%, you can opt to install the systems yourself.
Before you make the decision, you need to have a working knowledge of 220v electrical systems, wiring, refrigerant, and piping, as well as the required HVAC tools to get the job done. If you are going to extend the refrigerant lines, you will need to add more refrigerant to the systems, which does require an EPA certification.
The installation isn’t complicated but can be time-consuming, and it is recommended that two people perform the install. You will need to find your mounting location, drill the hole to the outside for the refrigerant and power lines, and mount the air handler.
The heat pump outside needs to be mounted on a flat surface without the obstruction of airflow and the wiring and refrigerant lines connected. The drain line needs to be straight, without loops, dips, or kinks, and at a slight downward angle to prevent clogging or overflow.
Once the system is mounted and connected, you need to wire the thermostat and remote kits (if applicable) and open the valves to allow the refrigerant to flow. After checking for leaks or other issues, you need to run the system and check for any error codes. Provided there is nothing; you are now installed and able to run the system.
Troubleshooting Guide: Understanding Gree Ductless Error Codes
Gree offers you the opportunity to see any issues the system may have. On the heat pump unit, there is a trouble indicator light. It will flash or be steady on to indicate the trouble code. Likewise, you can see the actual trouble codes on the remote control or the air handler unit LED screen.
The most common trouble code is the Gree e6 trouble code. This is a communication error between the heat pump and air handler. When this trips, the E6 code will display on the remote and air handler, and the trouble light on the heat pump will remain on with no flashing.
The E6 code means that the wiring between the indoor and outdoor unit is wrong, or that the communications control board is bad. If you have just completed the installation, the cause is going to be the wiring.
People Also Ask (FAQs)
What is the difference between Ducted & Ductless?
The Ducted mini split is a hybrid of a mini split system and a central AC. They easily replace old central ACs. Installers place a ducted split system into the existing ductwork of the home, which saves the homeowner money. Ducted systems aren’t as efficient (in general) as a ductless mini split system, but offer better zone coverage and more eye-pleasing aesthetics.
Can I access my Gree mini split owner’s manual online?
Yes. Gree offers all documentation for their systems online. You can find sales procures, certifications, ratings, and owner and installation manuals. From their documentation page, you just need to find your model and click the link to display or download the PDF.
What is multi zone cooling?
Multi zone cooling is when there are more than one air handler units (indoor side) in different rooms. Each air handler cools or heats a specific area, known as a zone. If you only have one air handler, you have a single zone system. However, if you have an air handler in the living room and one in the bedroom, you have a dual-zone system.
Does a Gree mini split come with a thermostat?
No. Mini split systems use an internal thermostat to read temperatures and switch the unit on and off as needed to follow programming. However, there isn’t a thermostat to use with the system. Instead, each air handler unit uses a remote control dedicated to that portion of the system. All programming, mode and fan selection is done on the remote instead of a thermostat.
How do I contact Gree mini split tech support for fixing problems with my AC?
Gree doesn’t offer tech support for their systems. All warranty claims, troubleshooting, and technical support need to go through the dealer or vendor who sold and installed the system for you. If you purchased your system and installed it yourself, you will need to find an authorized Gree dealer to ask for their assistance.
How much will it cost to have an HVAC contractor install a Gree mini split AC/heat pump?
According to Home Advisor, the average price to buy, install, and warranty a Gree system is between $1500 and $8000. While the national mini split system costs about $3450, a Gree system will be a little more because of their higher initial cost. If you already have the system, the installation alone will average about $500, depending on the number of zones to install.
Where do I find the best HVAC contractor in my area?
To take full advantage of the warranty, your system will need to be installed by an approved Gree installer. The only way to ensure the installer is certified by Gree is to use the Find an installer page on their website.
Where can I buy a Gree mini split AC?
The best place to buy a Gree mini split AC is through Amazon. The only other place to find them is through authorized dealers who will mark up the price, so they make a profit. To save you money, Amazon has the lowest current pricing on all Gree products and keeps older models in stock longer, which can save you even more money.
Gree systems are designed for homeowners looking for a long-lasting, reliable mini split system. While single-zone systems are available, Gree caters more to the multi-zone needs for whole-home coverage.
If you are looking for the best Gree mini split AC, but don’t know which one to pick, we recommend the Gree Livo+ 12,000 BTU model. It is affordable, simple, and efficient to meet all of your needs.
