Buying a new aircon is exciting, especially in Singapore’s hot and humid weather. However, poor installation can lead to weak cooling, higher electricity bills, and even long-term damage to your unit. Many homeowners don’t realise how important proper installation is for both performance and safety.
The good news is, most aircon installation mistakes are preventable if you know what to look out for. In this article, we’ll highlight the most common aircon installation mistakes, explain how they affect your system, and share practical tips to help you avoid costly installation problems — keeping your aircon running smoothly for years.
Why Proper Aircon Installation Matters
First of all, your aircon’s performance depends on more than just the model you choose.
If installed incorrectly, even the best unit will struggle to cool your room properly.
As a result, you might end up dealing with noisy operation, water leaks, and higher energy bills.
That’s why hiring an experienced and reliable installer is so important.
Common Aircon Installation Mistakes (And How to Avoid Them)
Wrong Aircon Size for the Room
Firstly, many people pick an aircon without considering the size of their room.
If it’s too small, it won’t cool the room effectively.
On the other hand, an oversized unit uses unnecessary energy and wears out faster.
Tip: Always consult a professional to determine the correct aircon capacity for your space.
Poor Placement of the Indoor Unit
Next, placing your indoor unit in the wrong spot can affect airflow and cooling efficiency.
For example, avoid placing it directly above heat-producing appliances or near windows where sunlight enters.
Tip: Install it on a solid wall, away from direct heat and obstructions, for even and efficient cooling.
Incorrect Outdoor Condenser Placement
In addition, the outdoor condenser should have enough space around it to release heat.
If placed in a cramped area without airflow, the unit will overheat and work harder, increasing your electricity bills.
Tip: Position the condenser in a well-ventilated, shaded area with at least 30–50cm of clearance on all sides.
Improper Drainage Installation
Another common issue is poor drainage setup.
If the drain line isn’t installed correctly, water may back up and cause leaks inside your home.
Tip: Ensure the drainage pipe has a proper downward slope and no blockages to allow smooth water flow.
Not Sealing Gaps Properly
Sometimes, installers forget to seal wall gaps or piping holes after installation.
As a result, cool air escapes, and outdoor heat enters, reducing your aircon’s efficiency.
Tip: Always double-check that all gaps around piping and wires are sealed properly with insulation or sealant.
