Air conditioning is a necessity in Singapore’s sweltering climate, making proper installation crucial for optimal cooling performance. However, many homeowners and businesses unknowingly commit installation mistakes that lead to inefficient cooling, increased energy bills, and costly repairs down the line.
In this article, we will highlight the most common aircon installation mistakes in Singapore, their consequences, and how to avoid them. Whether you are installing a new system or replacing an old one, being aware of these pitfalls can save you money and headaches in the long run.
1. Incorrect Aircon Size and Capacity
One of the biggest mistakes during aircon installation is choosing the wrong size or BTU rating for the room. Many people assume that a higher capacity unit will cool the room faster, but an oversized unit can lead to short cycling, where the aircon turns on and off too quickly, consuming more power and wearing out faster.
On the other hand, an undersized aircon will struggle to cool the room, leading to constant overworking and potential breakdowns.
How to Avoid It:
- Consult a professional to assess the room size, ceiling height, and insulation.
- Choose the right BTU rating based on the space. For instance, a 9,000 BTU unit is ideal for small bedrooms, while a 24,000 BTU unit is better for larger living areas.
- Consider factors like sunlight exposure and number of occupants to determine the appropriate cooling capacity.
2. Poor Positioning of Indoor and Outdoor Units
Improper placement of aircon units is another common installation error. The indoor unit should not be installed near heat sources, direct sunlight, or obstructed areas, as it will have to work harder to cool the room, wasting energy.
Similarly, the outdoor unit should be installed in a well-ventilated area, away from direct sunlight and debris. Placing it in a cramped, poorly ventilated space can lead to overheating and reduced efficiency.
How to Avoid It:
- Install the indoor unit at a higher position to ensure optimal airflow throughout the room.
- Keep the outdoor unit in a shaded, open area to allow proper ventilation and heat dissipation.
- Maintain a clear space around the outdoor unit to prevent blockages and ensure easy access for servicing.
3. Incorrect Slope of the Drainage Pipe
In humid Singapore, air conditioners generate a significant amount of condensation. A properly installed drainage pipe is crucial to direct the water away from the unit. However, many installations fail to account for the correct slope, leading to water backflow, leaks, and potential ceiling or wall damage.
How to Avoid It:
- Ensure that the drainage pipe has a gentle, downward slope to allow water to flow freely.
- Check that the drainage pipe is securely connected and free from clogs or kinks.
- Regularly inspect the drainage pipe for signs of leaks or blockages, especially after heavy rain or prolonged aircon use.
4. Poor Insulation of Refrigerant Pipes
Refrigerant pipes transport the coolant between the indoor and outdoor units. When these pipes are not properly insulated, they can lose cooling power, resulting in lower efficiency and higher energy bills. Moreover, condensation may occur, leading to water leaks and potential mold growth.
How to Avoid It:
- Use high-quality insulation materials specifically designed for refrigerant pipes.
- Ensure that the insulation is tightly wrapped and secured to prevent any gaps or air leaks.
- Inspect the insulation regularly for signs of wear, tear, or moisture buildup.
5. Inadequate Power Supply and Wiring
Installing an aircon without considering the electrical capacity of the property can be a serious mistake. If the power supply is not sufficient, the aircon may trip the circuit breaker, cause power fluctuations, or even lead to electrical hazards.
How to Avoid It:
- Hire a licensed electrician to assess the electrical system and ensure that it can handle the additional load.
- Use dedicated circuits for each aircon unit, especially for larger systems or multi-split units.
- Install high-quality circuit breakers and surge protectors to safeguard the system against power surges.
6. Skipping the Testing and Calibration Phase
After installation, some contractors may skip the testing phase, assuming that the system is functioning correctly. This oversight can lead to undetected leaks, poor airflow, or improper cooling, which can only be noticed after days or weeks of use.
How to Avoid It:
- Request a comprehensive test run of the aircon unit after installation.
- Check for proper cooling, even airflow, and absence of strange noises or leaks.
- Verify that the thermostat is calibrated correctly to maintain the desired temperature consistently.
7. Not Hiring Professional Installers
Attempting a DIY installation or hiring unqualified technicians may seem cost-effective initially, but it can result in serious installation errors. Incorrect wiring, poor mounting, and improper refrigerant handling can lead to costly repairs and even safety hazards.
How to Avoid It:
- Engage a certified aircon installer with experience in Singapore’s climate and property types.
- Look for companies that provide warranty coverage for their installation services.
- Check reviews and credentials to ensure that the contractor is licensed and reputable.
