Whether you’re looking to upgrade your cooling system or you’re installing a new unit in your commercial space, choosing the right air conditioner is just the first step.
Installation is just as important as selecting the unit itself, as proper setup helps to guarantee optimal performance, energy efficiency, and longevity for your air conditioner.
When it comes to commercial spaces, cassette air conditioners are an ideal and popular solution.
They offer discreet ceiling installation and 360° air distribution, and are a common choice for clinics, childcare facilities, and nursing homes due to the fact that they provide consistent, efficient cooling – without taking up valuable wall space.
This guide will take you through the essential steps for installing a cassette air conditioner and provide some quick tips on how to keep it running in peak condition, so you can get the best out of your unit.

How do you choose the right location?
Choosing the right location to install a cassette air conditioner is a key step for achieving even air distribution and ensuring the unit is easy to access for future maintenance.
In an ideal world, your unit should be centrally placed in the room, away from obstacles such as partitions or large furniture that can block airflow. But in spaces where it’s difficult to achieve a perfect setup, there are a few things to keep in mind.
First off, avoid installing your unit directly above electrical appliances or heat sources. The extra heat can interfere with the air conditioner’s performance – and in extreme cases can damage the unit.
Secondly, make sure there’s enough clearance between the unit and the walls, which allows for smooth airflow and makes for a far easier installation.
Remember, correct placement is absolutely key to maintaining a comfortable environment and prolonging the lifespan of your unit.
Prepare for installation: The tools and materials needed
Before you get started, you’ll want to make sure you’ve got all of the tools and materials needed for installation.
Basic tools:
● Mounting hardware
● A drill
● A saw or utility knife
● A measuring tape
● A spirit level
● A stud finder
● A step ladder
● Safety gear
Specialised tools for piping installation
● Flaring tool: Used for flaring the ends of copper pipes for secure connections
● Vacuum pump: Needed for removing air and moisture from the refrigerant lines
● Manifold gauge: Helps you to measure pressure levels during refrigerant charging
● Copper pipe cutter: Cuts copper pipes to the length you need
● Copper tube bender: Bends copper pipes to fit the right space and angles
● Reamer: Cleans and deburrs the inside of your pipes after cutting
● Gas leak detection spray or soap: Used to check for leaks in the refrigerant lines
If you’re not experienced with any of these specialised tools, it’s best to refer to a professional.
Having all of these items will make your installation process as smooth and safe as possible.
It’s also a good idea to refer to the manufacturer’s installation guide to make sure you have all of the specific materials and instructions that come with your unit. This will further help to make sure your installation is safe and help guarantee that you’re meeting professional standards.
Installation: A step-by-step guide
Let’s take a look at a step-by-step guide on how to best install your cassette air conditioner.
Step 1: Measuring and marking the ceiling space
As the saying goes, measure twice, cut once. Accurate measurements are the foundation of any successful installation.
Use your measuring tape and a spirit level to mark the precise location on the ceiling where the cassette unit will be installed. Make sure you’ve chosen an area that can support the weight of the unit and provides enough clearance for airflow and maintenance access.
Step 2: Cutting the ceiling and mounting the unit
Once you’ve marked your location, carefully cut through the plaster or drop ceiling using your saw or a utility knife.
Double-check that your cut is accurate and clean, and can accommodate your unit’s dimensions.
With your ceiling opened, securely mount the unit to the ceiling framework using the provided hardware, then do a final check to make sure it’s level and there’s room for even air distribution.
Step 3: Installing piping and drainage
Cassette air conditioners need proper piping and drainage to function properly. Run the refrigerant piping from the outdoor unit to your cassette unit, making sure that all of the connection points are tightly sealed.
Then install your drainage system to remove condensation from the unit which prevents it from pooling – angling the drainage pipes downward to prevent blockages and leaks.
Step 4: Insulation layer application
To avoid any buildup of condensation and energy loss, insulate your refrigerant pipes. It’s worth going for high-quality insulation materials that are specially designed for air-conditioning systems as they’ll give you the best results.
Having this proper insulation will boost your unit’s performance and help prevent any water damage to the ceiling.
Step 5: Connecting electrical wires
Next up is connecting the electrical wires. You’ll want to be extra careful with this step as handling any form of electrical connection requires caution. Make sure you turn off the power supply and check that no residual current is present before you start.
Follow the manufacturer’s wiring diagram closely, and ensure the connections are secure and compliant with your local electrical codes.
If you’re ever unsure about electrical work, it’s always best to consult a professional.
Step 6: Installing and securing the panel
Once your electrical installation is complete, it’s finally time for the last step – installing the outer panel that covers the cassette unit.
Line up the panel with your unit and then securely fasten them together. A well-fitted panel enhances the aesthetics of your unit, and also guarantees efficient airflow.
Step 7: Commissioning and trial run
Before you finalise your installation, it’s important to conduct a trial run to make sure everything is working properly.
Firstly, use your vacuum pump to remove air from the refrigerant lines. Then check for any gas leaks using your detection spray or soap. Once you’re confident that everything is working as it should be, you can test your system to make sure it’s operating.
Remember to check the airflow, temperature control, and drainage.
Maintenance tips
Routine maintenance is essential to keeping your cassette air conditioner in peak condition.
Clean the filters regularly to prevent dust buildup, and check the drainage system to avoid pooling and any leaks. You should also periodically inspect the refrigerant levels and insulation to maintain the energy efficiency of your unit.
By keeping up with these simple maintenance tasks, you can extend the life of your unit and consistently keep your commercial space cool.
Proper preparation and safe is essential for a smooth and successful installation.
While installing a cassette air conditioner, or any air conditioner, may seem straightforward, it’s important to carefully follow the steps outlined to ensure a successful setup.
For more complex installations, particularly in spaces with gypsum ceilings or challenging layouts, it’s always a good idea to consult a professional installer. Proper installation maximises the unit’s efficiency and helps to protect the structural integrity of your ceiling.
