Cassette AC Installation Step-by-Step Process, Requirements and Expert Tips

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.

What Are the Prerequisites for Cassette AC Installation?

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-by-Step Cassette AC Installation Process

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.

Common Mistakes to Avoid During Cassette AC Installation

• 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.

How Long Does Cassette AC Installation Take?

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.

Quick Takeaways

• 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
