A good AC can still cool badly if it is installed badly. Many “faulty AC” complaints in the first year are actually installation problems. Here are the most common mistakes and how to avoid them.
1. Choosing the wrong location for the indoor unit
Place it where air can spread across the room, away from direct obstruction by furniture, and not directly above where people sleep or sit.
2. An outdoor unit with poor airflow
The outdoor unit needs space to release heat. Fitting it in a tight, closed spot, or facing a wall, reduces cooling and strains the compressor.
3. Long, bent or kinked piping
Excess pipe length and sharp bends reduce performance. Pipes should follow the manufacturer’s limits and be routed neatly.
4. Weak brackets and supports
The outdoor unit is heavy and vibrates. Weak brackets can cause noise, damage or even a dangerous fall.
5. Poor drainage slope
If the drain pipe does not slope correctly, water can leak inside. See why AC water leaks happen.
6. Skipping a leak and vacuum check
Air and moisture in the lines can reduce cooling and damage the system. A proper installation includes checking the connections.
7. Poor electrical work
An AC needs suitable wiring, a proper plug or connection and the right MCB. Follow the manufacturer’s electrical guidance, including any voltage recommendations for your model.
8. Wrong AC size for the room
An AC that is too small runs constantly; one that is too large wastes money. Choose capacity based on room size and sun exposure. Not sure which type to buy? Read split AC vs window AC.
9. Not testing and explaining after installation
Ask for a cooling test, show you the remote functions and keep the installation details and warranty documents.

Frequently Asked Questions
Does installation affect how well an AC cools?
Yes. Incorrect placement, long or kinked pipes and poor drainage can all reduce cooling and shorten the AC's life.
Can I install a split AC myself?
It is not recommended. Installation involves wiring, piping and refrigerant lines and is best done by trained technicians.
Is installation covered by the AC warranty?
It depends on the brand and seller. Check what your warranty covers and keep your installation record.
