Fujitsu mini split heat pump systems are available in single zone and multi zone options. Installed cost starts at $4,800 for a small, single-zone unit. Prices can exceed $20,000 for a large, 5-zone system when main equipment, necessary accessories and labor are added in.
You can find cheaper prices on lesser brands. Fujitsu is considered one of the better brands by HVAC installers and repair technicians. It is a good brand to consider if you:
- Plan to make a long-term investment in your current home.
- Prefer professional installation to doing it yourself.
This is a comprehensive Fujitsu mini split heat pump buying guide with system options and comparisons, costs, pros and cons and the return on an investment from installing a Fujitsu mini split system.
Fujitsu General – That’s the company’s full name. But everyone simply calls it Fujitsu, so that is what we use (mostly) throughout this review.
Introducing Fujitsu Airstage
Fujitsu recently announced a global rebranding of its mini split HVAC systems – All Fujitsu mini split systems are now called Airstage mini split systems. The transition will take some time as wholesalers and retailers sell out of the old units, replacing them with Airstage systems.
You likely know that a mini split system consists of:
An outdoor unit or condensing unit is installed outside where it collects heat when in Heat mode and where it dumps heat in AC mode.
Outdoor units, also called condensing units, come in various sizes to match the needed indoor carpet and number of zones from 1 to 5. That’s the maximum # of zones for Fujitsu – 5.
Indoor units come in a bunch of types – Wall mounted, floor mounted, universal (put it low or high), cassette, etc. They are all described, with pros, cons, and costs, below.
Remotes – While wired wall controls can be (must be in some cases) installed for your system, all systems also come with a wireless remote for each indoor unit.
WiFi / Smart Home – WiFi modules are either standard or optional in all systems and are used with the Fujitsu FGLair App. When a module is installed, the systems can be controlled with Amazon Alexa and Google Home.
Details of what is available in Fujitsu indoor units are given below in the reviews of the single zone and multizone systems.
You’ll have the information you need to purchase a system online or discuss your Fujitsu mini split system choices with the contractor you select to install your system.
Which raises a good question…
Are Fujitsu mini split systems DIY?
No. By design, Fujitsu and most top brand manufacturers do not fill their units with sufficient refrigerant. This requires hiring a licensed technician with what’s known as a “refrigerant card.” It is the certification necessary to charge a system with refrigerant.
Fujitsu warranties also require installation by a licensed professional – a common industry practice.
Here is what the Fujitsu warranty states: “PROPER INSTALLATION – This Limited Warranty applies only to Systems that are installed by contractors who are licensed for HVAC installation under applicable local and state law (Licensed Contractor), and who install the System in accordance with: (a) all applicable building codes and permits; (b) FG [Fujitsu General] installation and operation instructions; and (c) good trade practices.”
Fujitsu Single Zone Mini Split Systems – Airstage Single Zone Systems
Fujitsu single zone systems have one outdoor unit and one indoor unit. That’s stating the obvious, perhaps. And there are 9 indoor unit styles.
What is unique to Fujitsu General is that the single zone systems are not mix and match. Each indoor unit type has its own outdoor unit series in various sizes.
Did you know? A total of 66 different systems can be configured based on the indoor unit you select and the outdoor unit sizes that match each indoor unit. That gives you a lot of customization for the right system size and performance you want.
Here’s an overview chart. Each indoor unit type with features, pros, and cons and more is discussed below the chart.
Fujitsu Single Zone System Options, Sizes and Efficiency
|Indoor Unit Type||System Sizes (BTUs)||SEER Rating Range|
|Wall Mounted||9,000 to 36,000||18 to 33.1|
|Floor Mounted||9,000 to 15,000||26|
|Universal Floor/Ceiling||18,000 & 24,000||16|
|Slim Duct||9,000 to 15,000||21.5|
|MSP Duct||12,000 to 48,000||16.5 to 21.3|
|Compact Cassette||9,000 to 18,000||20.8 to 22.5|
|Cassette||18,000 to 42,000||18.5 to 21.4|
|Air Handler||24,000 to 48,000||16.3 to 19.1|
Wall Mounted Series
You have 5 separate series to consider: Highest SEER with Wireless LAN network, Highest SEER, High SEER, XLTH low temperature heating, Entry Level.
And in terms of indoor unit style/design, you have up to 5 options depending on the series. All, of course, are wall mounted styles.
Systems and Features
Highest SEER with LAN: Available in 9K, 12K and 15K BTU sizes. SEER 25.3 to 33.1 based on size (smaller units are more energy efficient). Wireless WiFi control.
Highest SEER: Same as above but without WiFi control.
High SEER: Available in 9K, 12K, 18K and 24K BTU sizes. 22.5 to 26.5 SEER options. Wireless
XLTH: Extra low temp heating to -15F. Available in 9K, 12K and 18K BTU. WiFi LAN optional. 25.3 to 33.1 SEER.
Entry Level: Available in 9K, 12K, 18K, 24K, 30K and 36K BTU sizes. SEER ratings from 16 to 20 SEER.
These series are mounted high on the wall, usually above 7 feet. As a result, they are best suited to locations where air conditioning is used more than heater since cool air sinks.
However, they can be effective for heating too, especially when a ceiling fan is used in the area to circulate warm air from the ceiling back to floor level.
Pros: Wall mounted indoor units are typically the most affordable. They are easy to install, which also might reduce labor costs. A good range of efficiency levels including Energy Star efficiency is available.
Cons: Located on the wall, they might not push air to the furthest parts of a room or zone. Some consider a wall mounted unit to be a little intrusive, not as aesthetically appealing as a concealed duct or ceiling cassette.
Noise might be a concern for some as well when compared with more concealed types.
Floor Mounted Series
These indoor units mount on the wall near the floor or onto the floor.
There are two series which are identical except for the extra low temp performance of the XLTH Series and their efficiency levels.
Systems and Features
RLFF: Available in 9K, 12K and 15K sizes. SEER rating for each size is 26 SEER. The systems can provide heat in temperatures to -5F.
XLTH: The same as the RLFF with the exception of a base pan heater to avoid freeze-ups plus, which also allows the units to draw heat from outside air in temperatures as low as -15F.
These units are ideal for cold climates for two reasons. First, they offer full heating in very low outdoor temperatures. Secondly, units mounted at floor level, vs high-wall or ceiling, are better for heating.
You might still want to install a ceiling fan that will circulate risen heat back downwards for maximum comfort and efficiency.
Pros: Affordable compared to cassette and duct indoor units. Efficiency is very good.
Cons: They take up floor space. And when in AC mode, you might notice a lot of cold air near the floor with warmer air at head level.
These units give you installation flexibility.
Systems and Features
Just one series is available, and it comes in 18K and 24K BTU sizes. Both sizes offer a maximum 16 SEER cooling.
They make the most sense for residential use when mounted to the ceiling of a zone from 750 to 1,200 square feet. Another option is to install one beneath a window seat in a bay or bow window.
Pros: Versatility in where to mount them. They can be installed “flat,” such as under a platform – though that’s more likely a need in a commercial setting.
Cons: Limited number of sizes – just 2. And the series isn’t as efficient as most. It’s not Energy Star rated.
This large indoor unit mounts flat to the ceiling surface.
System and Features
The Large Ceiling Fujitsu Halcyon system comes in one size – 36,000 BTU. It offers 16 SEER efficiency.
These make the most sense in large, open areas like homes with an open floor plan. This is especially true for warm climates where air conditioning is used for most months of the year.
Pros: It produces a large volume of heated or air-conditioned air. And it is out of the way – mounted to the ceiling.
Cons: Only one size is offered. It is less efficient than many central heat pumps. Being that large, it might also be a little noisy.
These units are mounted in the wall, ceiling, or floor. For wall applications, they can be installed high or low depending on your home’s layout and whether heating or air conditioning is most important for your climate.
Ductwork runs from the indoor unit to 1-4 locations where air vents or grates are installed. Total ductwork is reduced compared to standard central heat pump systems.
You’ll need a wall thermostat: Because the units are concealed behind drywall, a remote-control signal to the air handler might not work. So, buying a wall thermostat is required with these systems.
The thermostat is wired to the air handler/indoor unit. And a remote is used, if desired, to control the thermostat.
Systems and Features
Available sizes are 9K, 12K and 15K BTU. All have a SEER rating of 21.5.
When you really don’t want to look at indoor units, preferring concealed equipment, this is a good choice for one to three rooms. Most are used in climates where air conditioning is required more than heating because they are often installed in ceilings.
Pros: Versatile installation options – either vertical or horizontal. Decent efficiency – it is Energy Star certified. Installed in the wall or in/near the ceiling, these units do not take up much space and can be concealed.
A single indoor unit with ductwork running from it to several vents may cost less than a standard multizone mini split system.
Cons: Prices can be higher than for wall mounted indoor units. Installation costs more too when the units are installed in a wall or ceiling rather than mounted on the surface.
Medium Static Pressure Ducts
These units offer higher static pressure than slim duct indoor units. This means that you can run a more extensive system of ductwork off them.
What is a medium static pressure ducted mini split system?
It has one outdoor unit and one indoor unit. The indoor unit is typically mounted in a ceiling, and a series of ducts is run from it to a single room or zone or to multiple rooms in your home. These are new ducts.
*The systems do not work with existing ductwork. Fresh ductwork is installed and connected from the indoor unit to each air vent.
You’ll need a thermostat: As noted above with the Slim Duct indoor units, a wall thermostat wired to the unit is required.
Systems and Features
These systems give you the most options. Sizes are 12K, 18K, 24K, 30K, 36K, 42K and 48K BTU. The three smallest are Energy Star certified. The range is 16.5 to 21.3 SEER.
Homeowners that want concealed equipment choose duct-type mini split systems. This system has the pressure to push air to multiple rooms through attached ductwork. Even a smaller 12K or 18K system can serve an entire dwelling, depending on square footage of the space.
Pros: More system sizes than most other options. The systems cost less than most multizone systems because ductwork material and installation costs less than individual indoor units installed for each zone. Finally, the only visible equipment indoors are the air vents.
Cons: Equipment costs are higher than for other single zone types. And they aren’t high efficiency.
These Fujitsu mini split indoor units are installed in the ceiling so that the grates are flush with the drywall. Most are installed in the center of the room or zone for the best air circulation to all parts of the room.
What’s the difference between a compact cassette and a standard cassette? The compact cassette grates are fewer square inches than standard cassettes of the same BTU capacity.
The indoor units are taller than standard cassettes, so you must be sure that there’s room above the ceiling for their installation.
Systems and Features
You can select from 9K, 12K and 18K BTU sizes. Efficiency levels are 20.8 to 22.5 SEER. A two-stage fan runs on low when low speed is sufficient to meet the room’s thermostat setting. This means quieter operation.
Consider a compact cassette when you want the indoor unit to be minimally visible. Also, they are ideal when ceiling area is limited.
Pros: An indoor unit installed in the middle of the room will naturally produce more balanced indoor comfort than one installed on a wall. The efficiency levels of these units meet Energy Star criteria – better than the efficiency of standard cassettes. And they take up less space than any other indoor unit type.
Cons: Equipment cost, and installation cost are higher than those for wall mounted and most other indoor unit types.
Cassette / Circular Flow Cassette
These standard ceiling cassette indoor units have 360-degree vents/louvers for airflow to every corner of the zone.
Systems and Features
Choose your size: 18K, 24K, 30K, 36K and 42K BTUs. Efficiency ranges from 18.5 to 21.4. There are 4 fan speeds – you select the right one based on the room size to make sure air is distributed all the way to the walls.
These systems are well suited to warm climates because the units are mounted in the ceiling, and cool air sinks. If you choose one for a cooler climate, you might find that the area near the floor remains chilly. As noted, a ceiling fan can assist in circulating the heat downward to the floor.
Pros: The cost is lower than compact cassette units. The 360-degree airflow helps to ensure balanced room temperature.
Cons: Efficiency is lower than most other Fujitsu mini split system options, so a cassette system might not be a good fit if your home experiences extremely hot weather.
Multi Position Air Handling Units
Yes, these are listed as single zone mini split systems because there is a single indoor unit. However, it should be obvious that they are intended to serve multiple zones in a dwelling – up to the entire dwelling.
When you already have ductwork or prefer it for air distribution in a new home, these indoor air handlers are the answer. Plus, the systems give you higher energy efficiency than most standard air source heat pumps.
You’ll need a thermostat: Because the units are installed in a central location, a remote-control signal might not reach them. A wall mounted thermostat wired to the air handler is needed.
Systems and Features
Both standard and XLTH systems are available in this series.
Standard: It comes in capacities of 24K, 30K, 36K and 48K BTUs and 17 to 19 SEER. These efficiency ranges are about in the middle or ratings for standard split system heat pumps.
XLTH: The extra low temp heating systems are offered in 30K, 36K and 48K sizes. SEER ratings for the XLTH units are 16.3 to 19.1. They are effective to 15 degrees below zero.
The ductwork angle was covered. These are whole-house systems. The rest is easy. Choose a standard system for moderate to hot climates. Select an XLTH system when freezing winter temperatures are common where you live.
Pros: Potentially lower total system cost when ductwork is already in place. That’s because a single air handler costs far less for the equipment and installation than 2-5 indoor units installed in various rooms/zones.
You’ll probably save money when building a home too because the cost of ductwork is lower than the cost of installing multiple indoor units.
Cons: The biggest drawback is that you can’t control individual zones with a ducted system. Yes, you can add a zone control system, but the price is high and might push your total project costs beyond those of a Fujitsu multizone mini split system. And even then, climate control in each zone would not be as effective.
Single Zone System Warranties
5/7 years: All these series except the XYZ Series have standard 7-year compressor warranties and 5-year parts warranties.
10 years: The warranty is boosted to 10 years on all parts if the unit is installed by a licensed contractor and the warranty is registered online (not necessary in California).
12 years: If the contractor is a certified Fujitsu Elite contractor, the warranty on all parts is 12 years.
How Much Does a Fujitsu Single Zone Mini Split Cost?
Here are prices for Fujitsu mini split systems installed by a professional contractor. Costs include equipment, all installation accessories, refrigerant for charging the system and labor costs.
Some installation accessories are optional – Choose a wall bracket or pad for the condensing unit, for example. A thermostat or WiFi module might not be required. Discuss the specific install options with your contractor to pinpoint exact costs for your system.
Fujitsu Single Zone Mini Split Costs
|Single Zone Type||System Sizes (BTUs)||Equipment Cost||Installed Cost|
|Wall Mounted||9,000 to 36,000||$2,775 – $6,975||$4,875 – $10,150|
|Floor Mounted||9,000 to 15,000||$3,350 – $4,985||$5,485 – $8,595|
|Universal Floor/Ceiling||18,000 & 24,000||$3,975 – $5,350||$6,135 – $8,885|
|Large Ceiling||36,000||$4,365 – $5,725||$6,500 – $9,375|
|Slim Duct||9,000 to 15,000||$3,065 – $5,695||$5,245 – $9,225|
|MSP Duct||12,000 to 48,000||$3,375 – $10,225||$5,535 – $13,885|
|Compact Cassette||9,000 to 18,000||$3,235 – $5,415||$5,335 – $9,175|
|Cassette||18,000 to 42,000||$3,550 – $8,675||$5,650 – $12,450|
|Air Handler||24,000 to 48,000||$2,495 – $3,785||$4,725 – $7,495|
Fujitsu Multizone Mini Split Systems – Airstage Multizone Systems
Fujitsu General also calls these multi-room mini split systems, and your options are systems that serve 2 to 5 rooms or zones.
Don’t Forget Slim Duct, Medium Static Pressure Duct and Air Handling Units
If you need a multi-room mini split system, you might have overlooked three options from the single zone list.
They are standard duct (or ducted), medium static pressure ducted and air handler units. All of them can be configured for multiple rooms or zones. They’re listed above because each system has one indoor unit – but the unit can be used to serve multiple zones through attached ductwork.
Give them consideration for your multizone project.
Putting a system together: It’s a mix-and-match process. If you, for example, need 36,000 total BTUs, you can choose indoor units that add up to 36,000 to around 42,000 – the indoor total can be up to 15% higher than the outdoor unit’s capacity.
And you can choose different indoor unit types for each zone if you wish.
Efficiency Note: Ducted systems using the Slim Duct indoor units are the least efficient. Non-ducted wall/floor/cassette units are the most efficient. Obviously, a system using a mix of each will have efficiency ranges in the middle. These are called “mixed” systems.
*A description of each indoor unit type with pros and cons follows shortly.
Multizone Fujitsu Airstage Outdoor Units
Most outdoor units can be matched with most indoor unit types. Again, that means a lot of customization options – and decisions.
Since it is the outdoor unit that largely determines the efficiency of the system, it makes sense to discuss them first.
Then, we’ll look at your options for single zone and multizone (multi zone or multi-zone) system configurations.
Fujitsu Airstage condensing units are available in 18,000 to 48,000 BTU units for multiroom systems.
But there is more to consider than size – standard heating vs extra low temperature heating. All Fujitsu General outdoor units provide air conditioning, of course.
Here are the two outdoor unit or condensing unit series, their sizes and efficiencies.
Fujitsu Multizone Outdoor Units
|Hybrid Flex Sizes||SEER / Cooling||HSPF / Heating|
|18,000 BTU||16 – 18||9.0 – 9.3|
|24,000 BTU||15.5 – 18||9.0 – 9.5|
|36,000 BTU||16 – 18||8.7 – 9.4|
|48,000 BTU||17.7 – 19.7||9.3 – 10.3|
|18,000 BTU||19 – 21.5||9.0 – 10.3|
|24,000 BTU||18 – 20||9.0 – 10.3|
|36,000 BTU||18 – 20||9.3 – 10.3|
Hybrid Flex Inverter Outdoor Units (Condensing Units)
Despite the impressive name, these are the standard-heating outdoor units.
The term “inverter” refers to the rotary compressor type used in almost all mini split systems from every manufacturer. Inverter compressors run at variable speed, from around 25% depending on the model to 100%.
Like vehicle cruise control, inverter systems work harder or less hard as needed to deliver the exact amount of heating or air conditioning needed at the moment.
Sizes: Hybrid Flex condensing units are available in 18K, 24K, 36K and 48K BTU sizes.
Heating Range: They can deliver heat in outdoor temperatures down to 5F.
Efficiency Range: 15.5 SEER to 19.7 SEER. 8.7 HSPF to 10.3 HSPF. This efficiency range is right in line with most standard split system heat pumps – though the most efficient units, which have SEER ratings in the low-mid 20s.
XLTH – Extra Low Temperature Heating Outdoor Units
These systems are designed as cold climate air source heat pumps. That means that they effectively pull heat into your home in sub-freezing weather.
Sizes: Hybrid Flex condensing units are produced in 18K, 24K and 36K options.
Heating Range: They provide adequate heat in outdoor temperatures down to -15F.
Efficiency Range: 18 SEER to 21.5 SEER. 9 HSPF to 10.3 HSPF.
Multizone Indoor Units
You have four choices for indoor units, also called air handlers and “heads.”
Wall Mounted: These are available in 7K, 9K, 12K, 14K, 18K and 24K sizes.
Floor Mounted: Choose from 9K, 12K and 14K options.
Compact Ceiling Cassette: 7K, 9K, 12K and 18K sizes are produced.
Slim Duct: 7K, 9K, 12K, 18K and 24K capacities.
Pros and Cons
The pros and cons of each indoor unit type are given in detail above in the Single Zone section. Here’s a summary:
Wall Mounted: Typically, the most affordable, they also offer good efficiency. On the downside, mounted on a wall of a large zone, they might not be effective in heating or cooling areas most distant from the unit. They are best for air conditioning rather than heating, since cool air sinks.
Tip: When heating, a ceiling fan can help circulate heat, which will naturally rise, back down toward the floor.
Floor Mounted: These are ideal for heating since they’re installed on or near the floor at a wall. But they take up a little bit of floor space. And located on one wall, getting balanced temperatures throughout the space might be difficult in a large room or zoned.
Compact Ceiling Cassette: These units are installed in the center of the ceiling. This makes them ideal for AC Mode. Plus, the air is more evenly distributed throughout the zone. Compact cassette indoor units cost more than wall mounted units.
Slim Duct: Installed in a wall or ceiling, vertically or horizontally, these units aren’t visible.
Supply and return ducts are connected to it that can serve multiple vents, depending on the system size.
In new construction and attic installation projects, you might save money with ducted runs to zones vs. having an indoor unit installed in each zone.
Fujitsu Multizone Mini Split Costs
Note that the Fujitsu multizone mini split system cost chart begins with equipment costs only and then shows separate lines for Professional Labor Costs and Total Installed Cost.
Equipment: This includes the outdoor unit, indoor units, and all installation accessories: Pad or bracket, refrigerant line, electrical wiring, and cover, shut-off, through-wall sleeve, drain pump, WiFi module, thermostat, and miscellaneous supplies.
Some parts are optional, and the prices include costs with and without things like a thermostat or WiFi module.
Professional Labor Cost: Prices are for labor plus refrigerant charge.
Total Installed Cost: These are costs for pro-installed Fujitsu mini split systems – though state and local taxes are not included.
|Hybrid Flex Systems||2 Zones||3 Zones||4 Zones||5 Zones|
|Wall Mounted||$5,425 – $10,775||$6,635 – $11,850||$9,100 – $13,335||$9,915 – $13,475|
|Floor Mounted||$6,575 – $12,985||$7,925 – $14,000||$10,950 – $15,585||$11,865 – $16,215|
|Compact Ceiling Cassette||$6,565 – $12,335||$8,125 – $13,295||$11,300 – $14,600||$12,350 – $15,390|
|Concealed Duct||$7,185 – $11,990||$8,435 – $12,950||$12,450 – $14,125||$13,500 – $15,175|
|XLTH Systems||2 Zones||3 Zones||4 Zones||5 Zones|
|Wall Mounted||$5,990 – $11,400||$7,200 – $12,485||$10,250 – $14,115||$10,475 – $14,335|
|Floor Mounted||$6,990 – $13,685||$8,400 – $14,815||$11,495 – $16,350||$12,445 – $17,075|
|Compact Ceiling Cassette||$7,050 – $12,950||$8,635 – $13,800||$11,865 – $15,450||$12,900 – $16,425|
|Concealed Duct||$7,775 – $12,800||$8,990 – $13,475||$12,985 – $15,200||$14,065 – $16,235|
|PROFESSIONAL LABOR COSTS||$2,450 – $4,400||$3,300 – $5,625||$4,000 – $6,700||$4,850 – $7,575|
Total Installed Costs
|TOTAL INSTALLED COST||$7,875 – $17,200||$9,935 – $19,100||$13,100 – $21,900||$14,765 – $23,810|
Installation Cost Factors
The major factor is time – How long does it take to install a mini split system?
A single-zone system can be installed in a day or less by a crew of two.
Add 2-5 hours per indoor unit based on how easy or difficult it is to access the installation location.
*Units installed in walls or ceilings without attic access might take longer. Drywall repair costs are not included in these prices.
Licensed mini split contractors charge $75 to $135 per hour for labor.
Fujitsu Elite installers typically charge more – up to $175 per hour.
Multizone System Warranties
5/7 years: The basic warranty is 5 years on parts and 7 years on the compressor.
10 years: If you register the warranty with Fujitsu in a timely manner, all parts are covered for 10 years.
12 years: If installation is done by a Fujitsu Elite contractor, you get a 12-year warranty on all parts.
Fujitsu Mini Split Return on Investment – ROI
The return on the money you spend on a Fujitsu mini split will be 65% to 80%.
That means if you install a $15,000 system today and sell your house in the near future, the sale price should be $9,750 to $12,000 higher than if you sold the home with the old system in place.
Exact return on investment is based on several key factors. Following these guidelines will maximize your ROI.
Climate and Efficiency: Match the efficiency to the climate. Where the weather is extremely hot, you’ll get a good return by choosing an Energy Star certified Fujitsu mini split. In moderate climates, like on the West Coast or Mountain states, a mid-efficiency system will bring a better return.
“The North”: If you install a mini split in a climate with long stretches of freezing winter weather, it will threaten your ROI.
Even if it’s a Fujitsu XLTH system designed for cold climates, some home buyers in the North will be scared off by a mini split, period. They’ll potentially pass up your home in search of one with a good ol’ gas guzzling furnace.
Price and Equipment Choice: A general rule of ROI is that the more you spend, the lower your return on investment will be. As a result, systems using lower-cost wall mounted indoor units will bring the best return.
Brand Value: Informed homeowners will prefer a Fujitsu, LG, or Mitsubishi system over a cheaper brand like Pioneer, one they’re not familiar with like Gree or a DIY MrCool.
So, if you’re buying for the potential resale value, it makes sense to choose a household name with an excellent reputation for durability and performance.
