Fujitsu Ductless Mini Splits: A Comprehensive Review and Guide

Fujitsu Mini Splits: An Overview

Fujitsu is a well-known and respected brand in the world of mini split systems, offering a variety of single zone and multi-zone options. In this article, we’ll break down the features and offerings of Fujitsu’s mini split systems, as well as discuss their pros and cons compared to other brands.

Single Zone Offerings

Fujitsu splits their single zone offerings into two main categories: wall-mounted and non-wall mounted. We’ll take a look at the wall-mounted options first, which they further categorize as good, better, and best.

Good: Entry level

For the longest time, Fujitsu offered two types in this group: RLB and RL2. The RL2 systems are 115-volt offerings that come in 9,000 BTU and 12,000 BTU capacities. However, neither of these models are Energy Star qualified and they can only operate down to 15 degrees Fahrenheit in heating mode.

The newer version of the entry-level wall-mounted systems is the LPAS1, which has a few Energy Star qualified options, but not all models. Keep in mind that the temperature range for these models varies, so pay close attention when selecting a system.

Better: LMA S1 and LMA H1 Models

The main difference between the LMA S1 and LMA H1 models is that the H1 models are considered “XL TH” or extra-low temperature heating systems. These systems can operate down to -15 degrees Fahrenheit in heating mode. Most models in this category are Energy Star qualified.

Best: LSA Z1 and LSA H1 Models

In this category, Fujitsu offers two different model numbers depending on the BTU capacity selected. The lower BTU capacity range offers built-in Wi-Fi, while the higher BTU capacity range requires an additional component for Wi-Fi capability. Note that only models with an “H” in their model number can reach the lowest heating temperature of -15 degrees Fahrenheit.

Non-Wall Mounted Options

Fujitsu’s non-wall mounted single-zone options include concealed ducts, ceiling cassettes, and floor mounted systems. The only system that offers XL TH is the floor mounted option, while the others can only reach a low heating temperature of -5 degrees Fahrenheit.

Multi-Zone Offerings

Fujitsu offers a range of multi-zone condensers, from 18,000 BTU two-zone systems up to 45,000 BTU two to five-zone systems. Depending on the system, they offer standard options that operate down to 5 degrees Fahrenheit and XL TH options that operate down to -15 degrees Fahrenheit.

Air Handler Options

Fujitsu’s multi-zone air handlers have transitioned from the older RLF1 model to the newer LPAS1 model, which can be used for both single-zone and multi-zone systems. Their non-wall mounted air handler options have also been modified to be more versatile and compatible with both single and multi-zone systems.

Considerations and Comparisons

When making a decision on whether Fujitsu is the right brand for your needs, it’s essential to consider some of their shortcomings.


Fujitsu does not honor warranty for equipment purchased from any online retailer. This may be a significant factor for some customers, and it’s recommended to consider alternatives like ACIQ or Stealth, which offer long warranties even for online purchases.

Temperature Range

Not all Fujitsu models offer the extra low temperature operation that may be needed in colder climates. Competitor brands like ACIQ and Stealth offer heating at lower temperatures as a standard feature, making them potentially better choices for northern regions.

Brand Recognition and Support

Fujitsu’s well-known brand status means that local contractors and installers are likely to be more familiar with their equipment, making it easier to find support and parts for your system. However, at, we also offer tech support and replacement parts for any system you purchase from us.


Fujitsu is a reputable brand with a variety of quality mini split system offerings. However, factors such as warranty and temperature range limitations may make alternative brands such as ACIQ or Stealth more appealing in certain situations.
