Cassette AC installation involves fitting a ceiling-mounted split AC unit into a suspended ceiling grid, connecting it to an outdoor unit via refrigerant pipes and configuring the drainage and electrical connections. Done correctly, a Cassette AC installation result is nearly invisible, only the grille is seen. Techno Power Aircons provides professional cassette AC installation services with certified technicians and post-installation testing.
Before Cassette AC installation begins, the following must be in place:
False/suspended ceiling: The indoor unit mounts inside the ceiling cavity.
Ceiling cavity height: Minimum 300-350 mm above the ceiling tile.
Access panel: Required for future servicing and filter cleaning.
Drain line routing: A gravity or pump drain must be planned before installation.
Electrical supply: A dedicated circuit sized to the unit's rated current.
Step 1 - Site survey: Techno Power Aircons surveys the ceiling cavity, locates the best position for airflow and identifies the outdoor unit location.
Step 2 - Ceiling opening and support: A frame is fixed to the slab above; the ceiling tile opening is cut to fit the cassette unit.
Step 3 - Indoor unit mounting: The cassette unit is suspended from the slab frame and levelled precisely - critical for proper drainage.
Step 4 - Refrigerant piping: Copper pipes are run between the indoor unit and the outdoor unit, insulated and tested for leaks.
Step 5 - Drain connection: The condensate drain is connected to a gravity drain or condensate pump if gravity drainage isn't possible.
Step 6 - Electrical connection: Power and control wiring is connected as per the manufacturer's wiring diagram.
Step 7 - Commissioning: The system is vacuumed, charged with refrigerant, started and tested for correct operation.
Incorrect levelling: Even a 1° tilt can cause drainage failure and water leaks onto the ceiling.
Insufficient access panel: Makes future servicing difficult and costly.
Under-sized refrigerant pipes: Causes performance loss and compressor damage.
No condensate pump backup: In areas with no gravity drainage, a pump is essential.
A standard Cassette AC installation for a single unit typically takes 4-8 hours depending on ceiling complexity and pipe routing distance. Techno Power Aircons provides a time estimate after the pre-installation site survey.
Ceiling requirement: Suspended ceiling with min. 300 mm cavity
Key steps: Survey → mount → pipe → drain → wire → commission
Critical detail: Precise levelling for condensate drainage
Duration: 4-8 hours for a standard single-unit installation
