In Singapore’s hot and humid weather, it’s tempting to leave your aircon running all day — especially during long work-from-home hours or overnight for a good night’s sleep. But have you ever wondered what actually happens when your aircon runs 24/7?
ChatGPT said:
💸 1. Higher Electricity Bills
First and foremost, leaving your aircon on all day can cause a big jump in your electricity bill. Even if you’re using an energy-efficient inverter model, nonstop use still adds up quickly.
According to local estimates, an average aircon servicing customer in Singapore who runs their unit 24 hours a day could spend about 40% more on electricity than someone who uses it moderately.
💡 Tip: To save energy, set your aircon temperature between 24°C and 26°C. Use a ceiling or standing fan to spread cool air more evenly throughout the room.
⚙️ 2. Faster Wear and Tear
Your aircon is designed for long use — but not nonstop operation. Running it 24/7 puts extra pressure on key parts like the compressor, fan motor, and evaporator coils.
Over time, this can cause:
Early compressor failure
Clogged filters from heavy airflow
A shorter overall lifespan
Regular aircon maintenance in Singapore can help detect early signs of wear and tear before they lead to costly breakdowns.
🦠 3. Increased Risk of Mold and Odor
Because your aircon runs all the time, the moisture inside doesn’t get a chance to dry. As a result, mold, mildew, and bacteria can start to grow quickly.
Before long, you may notice musty smells around the room. Even worse, it can cause allergies, coughs, or sore throats.
🧼 Solution: To avoid this, schedule a chemical wash or aircon mold cleaning in Singapore every few months. This simple step keeps your unit clean, fresh, and running efficiently.
🔧 4. More Frequent Servicing Needs
When your aircon runs nonstop, dust and dirt build up more quickly on the filters and coils. As a result, airflow becomes weaker and cooling efficiency drops. This forces your unit to work harder and use more energy.
To avoid overheating or sudden breakdowns, it’s best to service your aircon every 2–3 months instead of every 4–6 months.
📅 Pro Tip: Sign up for an annual aircon maintenance contract in Singapore. It’s a smart way to save money while keeping your unit clean and well-maintained all year round.
🔥 5. Fire and Safety Risks
When your aircon runs nonstop, the electrical parts can overheat — especially in older or poorly maintained units. Faulty wiring or blocked airflow can also raise the risk of short circuits or even fire hazards.
For your safety, always make sure:
⚡ Power sockets and cables are in good condition.
🧰 Professional aircon inspection in Singapore is done at least twice a year to detect problems early.
🌿 6. Environmental Impact
The longer your aircon runs, the more energy it consumes, increasing your carbon footprint. Choosing an eco-friendly aircon model or ductless AC system in Singapore can help reduce energy waste while keeping your room cool.
You can also improve efficiency by using:
Smart timers or energy-saving modes
Regular filter cleaning
Proper room insulation
These small habits can make a big difference for your comfort and the planet.
🧰 Maintenance Advice: How to Use Aircon Wisely
Here’s how to keep your aircon running efficiently — without spending too much:
✅ Use a timer to switch off your aircon after you fall asleep.
✅ Keep doors and windows closed to lock in the cool air.
✅ Clean the air filters every two weeks to maintain good airflow.
✅ Book aircon servicing in Singapore every few months for proper maintenance.
✅ Use fans with your aircon to spread cool air evenly and save energy.
Running your aircon 24/7 may seem convenient, but it comes with higher energy bills, faster wear and tear, and potential health and safety risks.
