In our hot and humid weather, aircon is more than a luxury—it’s a daily necessity. But what if your trusted unit is secretly the reason behind those rising electricity bills? Many homeowners overlook the early signs, only to discover later that their aircon has been working overtime and wasting power.
The good news is, you don’t need to be an expert to spot the warning signs. Here’s how to tell if your aircon is costing you more than it should.
1. Your Electricity Bills Keep Climbing
If your bill jumps even though your usage habits haven’t changed, it’s a clear red flag. A clogged filter, worn-out components, or low refrigerant levels can force your aircon to use extra energy just to keep your room cool.
Tip: Compare your current bills with those from the same time last year to spot unusual spikes.
2. Cooling Takes Longer Than Usual
When your aircon struggles to cool the room or leaves hot spots, it’s not just about comfort—it’s about efficiency. Dirty coils, blocked airflow, or refrigerant issues make the unit work harder, which means higher energy consumption.
3. Strange Noises or Unpleasant Smells
Rattling sounds, buzzing, or a musty smell are warning signs you shouldn’t ignore. They often mean there’s dirt, mold, or loose parts inside. These issues force your system to push harder, wasting both power and money.
4. Frequent Breakdowns
Do you find yourself calling for repairs more often? A unit that constantly breaks down is already losing efficiency. The more it struggles, the more electricity it consumes—and the more you end up paying.
5. Your Aircon is Getting Old
Most aircons last around 8 to 10 years. Beyond that, they become less efficient, even with regular servicing. Upgrading to a newer, energy-efficient model may actually save you money in the long run.
Why Servicing Matters
Here’s the truth: regular servicing isn’t just about keeping your aircon clean—it’s about keeping your electricity bills in check. Professional servicing clears out dust, restores airflow, checks gas levels, and makes sure every part runs at its best. For households that use aircon daily, servicing every 3–4 months is the sweet spot.
Frequently Asked Questions (FAQs)
1. Why is my aircon electricity bill so high?
Because the system is working harder than it should—usually from dirt buildup, low gas levels, or aging parts. Regular servicing prevents this.
2. How often should I service my aircon to lower energy use?
Every 3–4 months is ideal, especially if you run it daily in bedrooms or living rooms.
3. What’s the best temperature to set my aircon?
Around 25°C is the sweet spot—comfortable, yet energy-saving.
Your aircon should keep you comfortable, not burn a hole in your wallet. If you’ve noticed higher bills, slower cooling, or strange noises, it may be time to give your unit some attention.
