In Singapore’s hot and humid climate, the air conditioner is one of the most essential appliances in every home. But with aircon usage being so common, it’s no surprise that many myths and misconceptions have developed over the years. Unfortunately, believing these myths can lead to higher electricity bills, poor cooling performance, and even premature system breakdowns.
To help you make smarter decisions (and prevent unnecessary repairs), here are the top aircon myths every Singapore homeowner should stop believing.
Myth 1: “Setting the temperature lower cools the room faster.”
The truth: Your aircon cools at the same speed regardless of whether you set it to 16 or 24 degrees Celsius. The thermostat only determines how cold the room will eventually get and not how quickly it gets there.
Setting your AC to the lowest temperature simply makes the system run longer, wasting energy and putting extra strain on the compressor.
Better approach: Keep your setting between 24 to 26 degrees Celsius, the optimal range for comfort and efficiency in Singapore.
Myth 2: “I don’t need servicing if my aircon is still cold.”
The truth: Aircon performance declines gradually, so many homeowners don’t notice issues until its too late. Even if the system feels cold, dirt may be building up inside the fan coil, drainage pipe, or condenser.
Skipping servicing can eventually lead to:
- Water leaks
- Weak airflow
- Higher electricity bills
- Compressor failure
In Singapore, where aircons run frequently, schedule servicing every 3–4 months for optimal performance.
Myth 3: “Bigger aircon = better cooling.”
The truth: A bigger BTU doesn’t always mean better. An oversized unit cools the room too quickly, causing the compressor to start and stop repeatedly. This leads to:
- Higher electricity consumption
- Inconsistent temperatures
- Poor humidity control
- Faster wear and tear
Always choose a system that matches your room size. For example, a typical Singapore bedroom usually needs a 9000–12000 BTU unit and not more.
Myth 4: “Running the aircon 24/7 is fine as long as the temperature is high.”
The truth: Even at a higher temperature, running your aircon non-stop wears down the compressor, increases component fatigue, and accelerates the need for repairs.
If you prefer long operating hours, consider:
- A smart timer or sleep mode
- A high-efficiency inverter model
- Regular servicing to reduce stress on the system
Myth 5: “Chemical wash or overhaul is needed every year.”
The truth: Not true. Chemical treatments should only be done when there are issues like:
- Persistent water leaks
- Stuffy or weak airflow
- Heavy mould buildup
- Poor cooling despite regular servicing
A reputable contractor will assess your unit first instead of recommending unnecessary services. Most households only require a chemical wash every 1–2 years, depending on usage.
Myth 6: “Aircons don’t cause allergies, only dust does.”
The truth: A poorly maintained aircon can worsen allergies. Dirt, mould, and bacteria thrive in warm, moist components like filters and drain pans. When circulated into your room, they may trigger:
- Runny nose
- Itchy eyes
- Asthma symptoms
- Throat irritation
To reduce indoor allergens, wash or replace filters monthly, especially during Singapore’s humid months.
Myth 7: “All aircon servicing companies offer the same quality.”
The truth: Servicing quality varies significantly. Some contractors only clean the surface, while others inspect drainage systems, check gas pressure, and clean coils thoroughly.
Choosing the right company can be the difference between:
- A healthy, long-lasting aircon
- OR
- Frequent breakdowns and costly compressor failures
This is where trusted professionals like Infinity Air make all the difference.
