Things to Consider

Getting a mini split is a significant investment. Due to that, it’s important that you’re not wasting your money on the wrong type for you. The most important feature will be the power, but there is also plenty of other things to think about.

Due to this, we thought it was the best idea to write a buying guide to give you all the info to make the right decision. To help you with your choice, we’ll go through all the key features and explain the terminology we’ve already seen. If you’re still in any doubt, then hopefully, our FAQs section will clear that up for you.

Advantages of Fujitsu mini split heat pumps

There are many great reasons to get a mini split, and here, we’ll look at the main ones.

  • Discreet installation – The indoor unit is going to be placed near the ceiling, and the other unit will be outside. This means that installation can be discreet, and your unit won’t be an eyesore. They also give you plenty of versatility, as you can install them anywhere.
  • Maintaining temperature – Due to the level of control over these mini splits, you can ensure that you always have the perfect environment for you. This means you aren’t constantly changing the settings, as can be the case with other heating systems.
  • Silent operation – It’s important to note that not all mini splits are quiet. When you get a high-quality model, such as one of those we’ve looked at here, you get the benefits of a powerful system with a minimum of noise.
  • Improve air quality – With their internal filters, these mini splits will also cut down air pollutants and improve the air quality. It’s a feature some heating/cooling systems don’t have.

How to pick the best Fujitsu mini split

When buying a Fujitsu mini split, you know that you’ll be getting a supreme level of quality that you can rely on. It means that these mini splits have a lot in common, but there are also some key differences.

The biggest difference will be in power level, and it’s essential to know the rough square footage of the area you want to heat. After that, factors such as the functions, efficiency, and dimensions are going to be crucial.

As we go through all the key features here, it’s a good idea to make a note of how important they are to you. By the end, you should have a clear idea of what you need.


British Thermal Units are used to measure heating and cooling power in AC systems. All you need to know is that the larger the room you have, the more powerful unit you’ll need. You’ll see two separate ratings of both nominal cooling and heating to denote its power in both aspects.

A small room of around 200 square feet may only need 6,000 BTU’s, whereas a large 1500 square foot space may need a unit that can produce around 24,000 BTU’s, such as the Fujitsu 24,000 BTU Mini Split (24RLXFW).

It’s a good idea to get a rough measurement of your room and choose a system to match that. If in doubt, it’s always wise to get a more powerful unit.

SEER rating

SEER stands for Seasonal Energy Efficiency Ratio, and it is a measure of how efficient the unit is going to be. It aims to simulate a typical season and shows you energy savings that can be made. The higher the number is, the more you can save, with the most efficient commercial machines reaching a SEER of around 30.

There is a minimum standard now in place of 13 SEER, so all the machines you see now will be at or above that level. A SEER of around 16 is brilliant, and it will give you high efficiency. Anything above that, such as the 29.3 on the Fujitsu 12,000 BTU Mini Split (12RL2), is amazing to provide that money economy in the long run.

Compressor motor power

As well as the heating and cooling power output, you need to know how much power these units will require. This will have a large impact on the overall cost of the unit and also how it will be installed. This will be measured in watts, but you also need to consider the voltage required.

Most US homes are limited to 120V, and this is fine for smaller mini splits that don’t require a huge level of power. Some units might require 240V, which most outlets aren’t capable of. In these instances, you’ll either need to get a specific outlet for this or hardwire the unit. This will often require professional installation.

Split system dimensions

Before buying your split system, you need to know where you are going to place it and if you have enough space. Prior thought needs to go into the installation. These are called split systems as you have the outdoor compressor/condenser and indoor air-handling unit.

The indoor units are usually fairly compact and can be placed near to the ceiling. This keeps them out of the way and gives you plenty of flexibility in terms of placement. Since the compressor/condenser unit is usually a lot bigger, but as it will be outside, the dimensions are rarely an issue.

Remote control

The remote control is going to make your life a lot easier. These units have plenty of functions, and you want to be able to adjust the mini split to your needs. All of the models that we’ve looked at here, including the Fujitsu 24,000 BTU Mini Split (24RLXFW), come with remote control are all very easy to use.

Other types of mini split systems without a remote control are much harder to use, and you won’t have the same level of comfort provided.

Modes and timer

There are various modes that you’ll see on these devices. Many people love to have timers that you’ll see on the likes of the Fujitsu 15,000 BTU Mini Split (15RLS3), which give you full control over the unit.

Other features help keep you comfortable, such as automatic airflow adjustment, auto/cool/dry/fan/heat modes, low ambient, and cold prevention. The Fujitsu 9,000 BTU Mini Split (9RL2) has all these features and the ultimate level of control.

What else can be important?

As well as the key specifications, there are a few other features to look out for. The design deserves some consideration as you want to make sure it fits in your room. Also, the filter can be a key feature. It allows you to have high-quality air, and it’s worth checking how much replacement costs.

It’s crucial to check the noise level. If you’re getting a loud hum, that can be very annoying.

Thankfully, all the mini splits that we’ve looked at here can remain near silent. It’s a feature of all Fujitsu models that even the outdoor unit makes very little noise.


The prices that we have looked at here range from around $1,000 to $4,000. As you can imagine, the price here is going to have a direct correlation to the power level. The most expensive unit is the Fujitsu 36,000 BTU Mini Split with its immense coverage, and at the bottom end of the scale, we have the Fujitsu 9,000 BTU Mini Split.

Between those figures, you get models such as the Fujitsu 15,000 BTU Mini Split, which is priced at around $2,200.

All of these are fairly priced for their power level and offer impressive value for money.


Is it hard to install a Fujistu mini split?

Unless you are highly competent in DIY and are used installing units with refrigerant lines, it can be quite tricky. For most people, installing one of these models is going to be well above their skill level, which is why it’s usually recommended to call a professional.

As these systems are ductless, paying for installation shouldn’t be that expensive. An expert will connect the two units in the most efficient manner while being able to feed through the refrigerant lines, drain line, and electric line. These units are a significant investment, and therefore, it makes sense to have perfect installation.

Do Fujitsu mini split heat pumps come with a warranty?

Yes, these systems come with a fairly long warranty with individual parts often covered separately. The Fujitsu 15,000 BTU Mini Split, for example, comes with a 7-year compressor warranty and a 5-year warranty on parts. Larger models often come with a 6-year compressor warranty with 2-years on parts.

You also have the opportunity to get an extended warranty if your unit is installed by a licensed contractor. Systems that have been registered and installed by an ‘Elite Contractor’ will have a 12-year warranty on both the compressor and parts.

How will a Fujistu mini split system affect my electricity bill?

Mini split systems are highly efficient due to their use of refrigerants and fans. It makes them much cheaper to run than traditional heating systems, and also, you have that benefit of cooling than required.

Most systems will only cost around $50-$100 to run monthly when constantly running. The exact cost is, of course, going to depend on the power requirements of the unit and the climate you are in.
