Wrong Unit Placement: The First and Most Costly Mistake
Indoor unit placement determines how well a room is cooled. Mounting the indoor unit on a wall where its airflow is blocked by a ceiling fan, curtain track, or partition wall means the room will have hot and cold zones regardless of the AC capacity. Outdoor unit placement is equally important, placing it in a confined alcove without adequate clearance for airflow will cause the compressor to overheat.
- Indoor unit should be on the wall opposite the longest dimension of the room
- Minimum 15 cm clearance above the indoor unit to ceiling; minimum 1 m to the nearest obstacle on the discharge side
- Outdoor unit: minimum 30 cm clearance on all sides; the discharge side needs 50 cm or more
- Never place the outdoor unit in a fully enclosed space, it must reject heat to the outside air
Drainage and Pipe Installation Errors
The condensate drain pipe must slope continuously from the indoor unit to the outdoor exit point. Any upward section or inadequate slope causes water to pool in the pipe or drain tray, leading to overflow. In Goa, where condensate volumes are high, proper drain installation is not optional.
- Minimum 1:50 slope on drain pipe, steeper is better; never flat or sloped backward
- Use large-bore drain pipe (16 mm minimum), smaller pipes block faster under Goa condensate volumes
- Refrigerant pipes must be properly insulated, uninsulated pipes sweat and drip in humid Goa air
- Secure all pipe runs to prevent sagging, sagging creates the flat sections that block
Electrical Installation Mistakes
Under-rated wiring, missing MCB protection, and loose connections are common installation shortcuts that create fire and equipment damage risk. In Goa where voltage fluctuations are common, correct electrical installation is critical.
- Dedicated circuit for each AC unit, never share an AC circuit with other heavy loads
- Correct wire gauge for the AC capacity, undersized wire overheats and degrades insulation
- MCB at the distribution board: correctly rated for the AC load
- Earthing: outdoor unit must be properly earthed, moisture and salt air make this essential in Goa
How to Verify Your AC Was Installed Correctly
After installation, there are several checks you can perform before the installer leaves. These should always be completed before signing off on any installation job.
- Ask the installer to run the AC in cooling mode for 15 minutes and confirm cold air, no water drip, and no unusual noise
- Verify the drain is flowing by checking the outdoor pipe outlet during operation
- Check that the refrigerant line insulation covers all exposed pipe from indoor to outdoor
- Confirm the MCB is correctly labelled at the distribution board and trips cleanly when tested
- Insist on a copy of the installation checklist and warranty card registration before installer departs
