Traditionally, air conditioners arrive with wall-mounted air handlers. There are several reasons why. For one, wall-mounted air handlers were the first type of air handlers to be developed. Additionally, wall-mounted air handlers are the easiest to install of all mini split indoor air units. Also, people are more accustomed to wall-mounted air handlers.
However, recently, we’ve seen new mini split air handler options emerge, from floor-mounted cassettes to ceiling-hanging units. However, a smart option today is the ceiling cassette.
Concealed, sleek, and generally very attractive, ceiling cassettes ensure a clean installation without compromising airflow. Ceiling cassettes offer better distribution because you can place the cassette at the center of the room.
So, should you consider a ceiling cassette mini split and, if so, what factors should you consider during shopping? We answer these and many other ceiling cassette mini split questions shortly. First, though, a review of some of the best mini-split ceiling cassettes.
What is a Ceiling Cassette?
Ceiling cassettes, also known as ceiling-mounted mini-split systems, are mini split air handlers mounted on the ceiling rather than installed on the floor or wall.
They are also different from ceiling-hung air handlers. Whereas the ceiling-hung air handler dangles from the ceiling, ceiling cassettes recess into the ceiling such that only the grille is visible. The rest of the unit is tucked away into the ceiling and remains invisible to the people below.
Ceiling cassettes discharge air from up to four sides of the cassette unit. This quality alone makes them a better option at air distribution than many other mini split air handlers, including wall-mounted air units. Also, you can install the cassette anywhere on the ceiling, though experts recommend centralized positioning for the best airflow.
Pros and Cons of Ceiling Cassettes
The following are several reasons to consider a ceiling cassette mini split for your next air conditioning project and a few limitations to keep in mind.
Ceiling Cassette Mini Split Pros
Ceiling cassettes aren’t yet as popular as wall-mounted air handlers. However, more people are opting for the cassette today.
Attractive recessed installation
This is arguably the biggest attraction of ceiling cassette mini-splits. About 90% of the air handler is tucked away inside the ceiling, with only the grille visible. It’s, by far, the most low-profile mini split installation option if you’re looking for a low-profile appearance. It’s also better for general indoor aesthetics.
Although wall and floor-mounted mini split air handlers are more space-saving than, say, portable air conditioners, they can still get in the wall. Wall-mounted air handlers, for instance, take up valuable space on the wall, meaning you have to find alternative wall space for your family photos and artwork. On the other hand, ceiling cassettes are entirely out of the way.
More power, less noise
Since the size of the air handler no longer matters because the bulk of it stays behind the ceiling anyway, you can have a more powerful fan inside the air handler without adverse consequences. What’s even better is that you can have a bigger fan without necessarily creating more noise as most of the sound remains behind the ceiling. This partly explains why ceiling cassettes are some of the quietest mini split air handlers.
Central positioning and 4-way airflow
A significant limitation of wall-mounted air handlers is that they can only install on one of the four walls. Now, imagine how much effort it takes to move cool (or warm) air from the air handler at one end of the room to the opposite wall! You may have a very weak airflow at the other end. Ceiling cassettes are centrally positioned and support 4-way airflow for better, more even air distribution.
Ceiling Cassette Mini Split Limitations
Despite the many advantages, ceiling cassette mini-split systems come with a few downsides that you need to keep in mind as you plan your shopping;
High price tags
Ceiling cassettes have the highest price tag of all mini-split air conditioners. A quick comparison shows that you’ll pay up to $500 more for the same single-zone mini-split if it comes with ceiling cassette air handlers.
More complex, expensive installation
Typically you need a licensed professional to install a ceiling cassette. We haven’t come across a manufacturer that allows DIY installation for ceiling cassettes. Additionally, the installation is usually more expensive because you need more wire and line set to run the AC to the center of the ceiling.
Factors to Consider When Shopping for a Ceiling Cassette Mini Split
Everyone has their preferences. However, a few considerations are critical when shopping for a ceiling cassette mini split air conditioner.
- Size of the AC in BTUs: The size of the mini-split and the capacity of each air handler (for multi-zone systems) determine how much space you can cool (or heat).
- Size of the ceiling cassette (in square inches): Ceiling cassettes vary in physical dimensions. Make sure to choose a size you’re comfortable with.
- Aesthetics: Since ceiling cassettes are mostly popular for their aesthetic qualities, make sure to choose a style and design that appeals to you. The finishing is critical.
- Energy efficiency: The energy efficiency of a mini-split is measured in SEER and EER values. Ideally, you want a unit rated 16 SEER or higher and 9.0 EER or higher.
- Noise level (in decibels): Ceiling cassettes are supposed to be quieter than other air handler types. You want air handlers rated 45 decibels at worst.
- Remote control: Unlike wall and floor-mounted air handlers, you can’t control the ceiling cassette from the onboard control panel. Therefore, the remote control is vital. Some models also have wired wall-mounted controls, while advanced models support smartphone control via apps and voice applications.
- Other features: A programmable timer, auto-restart, and 4-way airflow are some of the features to consider. Also, some consumers prefer heat pump mini-splits that provide supplemental heat during winter. The heat pump may even have a dehumidifier and a Fan-Only mode.
- Warranty: The good news is that most ceiling cassette mini-split systems have warranties. Nevertheless, it’s also nice to confirm the length of the warranty and its specifics. What does it cover and what isn’t covered?

2. GREE 18,000 BTU 16 SEER Ceiling Cassette Mini Split AC/Heat Pump
Another excellent choice for a single-zone ceiling cassette mini split is the GREE model UMAT18HP230V1AC-S. It’s slightly bigger (capacity-wise) than the Pioneer above at 18,000 BTU.
However, it’s slightly less efficient at 16 SEER, which isn’t too bad, though. Any mini-split system from 16 SEER onwards is sufficiently energy-efficient.
The package includes an outdoor condenser, one indoor ceiling cassette, a grille for the ceiling cassette, and a handheld remote with remote lockout. In addition, an XK-60 wall-mount controller is available separately if you’d like convenient wall control in addition to the handheld remote. Unfortunately, the required 1/4” x ½” line set is sold separately. All other accessories are also sold separately.
The ceiling cassette is a multi-speed air handler with 4-way air discharge. It’s tethered to a wired controller and features swing louvers for better airflow. It also has an internal condensate drain pump and a power-failure recovery feature that allows it to resume operations in the previous settings following a power interruption.
