Just moved into a newly renovated home and noticed a strange “chemical” smell when you turn on your aircon? You’re not alone.
Many homeowners in Singapore experience this. While it may seem like the aircon is the problem, the real cause is often something else—VOCs.
So, what are VOCs, and why do they make your home smell like this? Let’s break it down.

What Are VOCs?
VOCs stand for Volatile Organic Compounds. These are gases released from certain materials commonly used in renovations.
You’ll find VOCs in:
- Fresh paint
- New furniture
- Adhesives and sealants
- Flooring and laminates
- Cleaning products
Because of Singapore’s indoor lifestyle and aircon use, these gases can build up inside your home.
Why Does the Smell Come Out When You Turn On the Aircon?
Here’s where it gets interesting.
Your aircon doesn’t create the smell—it circulates the air inside your room. When VOCs are present, the aircon spreads them more evenly.
As a result:
- The smell becomes stronger
- It feels like it’s coming from the aircon
- The room may feel “stuffy” or “chemical-like”
This is why many people think their aircon is the source.
Is It Dangerous?
Short-term exposure to VOCs may cause:
- Headaches
- Eye or throat irritation
- Dizziness
- Unpleasant smell
For most people, it’s not immediately dangerous. However, long-term exposure—especially in poorly ventilated spaces—can affect health.
This is why proper air quality management is important after renovations.
How Long Does the Smell Last?
The smell can last anywhere from:
- A few days
- Several weeks
- Even months (in some cases)
It depends on:
- Materials used
- Ventilation
- Humidity levels
In Singapore’s humid environment, VOCs can linger longer.
How to Get Rid of the “Chemical” Smell
1. Improve Ventilation
First, open windows and allow fresh air to circulate. This helps remove trapped VOCs.
👉 Do this daily, especially after renovation.
2. Run Your Aircon (But Properly)
Although the aircon spreads the smell, it also helps with air circulation and humidity control.
👉 Tip:
- Use fan mode or cooling mode
- Combine with open windows when possible
3. Use Air Purifiers
Air purifiers with activated carbon filters can help remove VOCs from the air.
4. Clean Your Aircon System
Sometimes, renovation dust can enter your aircon system.
👉 A professional aircon servicing Singapore can:
- Remove dust and particles
- Improve airflow
- Prevent odors from lingering
5. Consider a Chemical Wash
If smells persist, your aircon may need deeper cleaning.
A chemical wash aircon Singapore service can:
- Clean internal coils
- Remove trapped contaminants
- Restore fresh airflow
How to Prevent This in the Future
Before or after renovation:
- Choose low-VOC materials
- Ventilate your home regularly
- Schedule aircon cleaning after renovation work
- Avoid sealing the house completely right away
When to Call a Professional

- Doesn’t go away after weeks
