Our POV: How can air-con contractors in Singapore tackle air-conditioning trap?

We have come across an interesting perspective from CNA regarding a topic that is very close to our heart: air-conditioning!

But first, what is "air-conditioning trap"? It is the reliance on air-conditioning that risks creating a cycle where cooling buildings contributes to even more heat and higher energy use for the planet. As temperatures rise due to climate change, the demand for air-conditioning continues to grow, which increases electricity consumption and emissions.

Some quick stats on Singapore's cooling demand:

• Air-conditioning can account for up to 40–60% of a household’s electricity use

• Cooling demand is expected to rise as temperatures increase

• Efficient building design can significantly reduce cooling needs

As an air-conditioning contractor working on projects across Singapore, we see this challenge from the ground. In such tropical climate, air-conditioning is not a luxury — it is essential for comfort, productivity and even safety in many environments.

However, the real issue is how we tackle air-conditioning trap with design and the use cooling systems.

Many buildings still rely on outdated designs where systems are oversized, poorly zoned, or inefficiently operated as "they are still working". But this also means lower energy efficiency that causes higher electricity bills and maintenance with the need to change spare parts more often.

From our experience at Poh Meng Engineering, several practical improvements can make a big difference with better planning and modern technology:

• Proper cooling load calculations and system sizing

• Energy-efficient inverter and VRF systems

• Chilled water cooling system

• Smart controls and zoning to avoid overcooling

• ⁠Integration with building design such as shading, insulation and ventilation

• Regular servicing and system optimisation

Instead of viewing cooling as the problem, we should focus on smarter cooling solutions that balance comfort, energy efficiency and sustainability.

In reality, such efforts are not smooth sailing. Challenges that air-con contractors also face include:

• consumer buy-in for new technology i.e. questioning on the equipment life-span by comparing with conventional air-cons that could "last more than 10 years"

• higher initial costs

• building expertise through steep learning curve and intensive trainings

At Poh Meng Engineering, we strongly believe in sustainability that will move us forward into the future. Contact us if you are looking for a reliable air-con contractor in Singapore.
