Singapore’s hot and humid climate means air conditioners run almost every day. While Mitsubishi Aircon are well known for their energy efficiency, improper usage and lack of maintenance can still result in high electricity bills. If you’ve noticed your monthly utility costs increasing, there are several practical ways to reduce energy consumption without sacrificing cooling comfort.
At Letscool Aircon Singapore, we’ve helped thousands of homeowners improve their aircon performance through professional servicing, maintenance, and installation. This guide shares expert tips to help you maximize your Mitsubishi airconditioner efficiency while extending its lifespan.
Why Does Your Mitsubishi Aircon Consume More Electricity?
A Mitsubishi aircon is designed to operate efficiently, but several factors can increase power consumption over time:
- Dirty air filters restricting airflow
- Dust accumulation on evaporator coils
- Low refrigerant gas levels
- Blocked drainage systems
- Worn-out fan motors
- Incorrect temperature settings
- Poor installation practices
Regular maintenance prevents these issues and ensures your air conditioner operates at peak efficiency.
1. Service Your Mitsubishi Aircon Every 3–6 Months
One of the easiest ways to reduce electricity consumption is through regular servicing.
Dust, dirt, and mould build up inside the indoor unit, forcing the compressor to work harder to maintain the desired temperature.
Professional servicing includes:
- Cleaning filters
- Washing evaporator coils
- Checking refrigerant pressure
- Cleaning drainage pipes
- Inspecting electrical components

2. Clean or Replace Air Filters Regularly
Dirty filters block airflow, reducing cooling efficiency.
Experts recommend cleaning reusable filters every two to four weeks, especially in Singapore’s dusty environment.
Benefits include:
- Improved airflow
- Faster cooling
- Lower electricity bills
- Better indoor air quality
Even a slightly clogged filter can increase electricity usage by up to 15%.
3. Set the Temperature Between 24°C and 25°C
Many homeowners believe setting the aircon to 18°C cools a room faster.
In reality, it simply makes the compressor run longer, increasing electricity consumption.
The Energy Market Authority recommends maintaining temperatures around 24–25°C for optimal comfort and energy savings.
4. Use Mitsubishi Inverter Technology Properly
Modern Mitsubishi inverter systems automatically adjust compressor speed according to room temperature.
Avoid turning the aircon on and off repeatedly.
Instead:
- Leave inverter mode running.
- Maintain a consistent temperature.
- Close doors and windows.
This helps reduce compressor workload and saves significant energy.
5. Schedule Professional Maintenance
Routine maintenance is more than basic cleaning.
Professional technicians inspect hidden components that affect energy efficiency.
Maintenance includes:
- Electrical safety inspection
- Gas pressure testing
- Fan motor inspection
- Coil cleaning
- Performance testing

6. Perform a Chemical Wash When Necessary
If your Mitsubishi aircon has poor cooling performance, unpleasant odours, or water leakage, standard servicing may not be sufficient.
A chemical wash removes stubborn dirt, mould, bacteria, and grease from internal components.
Benefits include:
- Restores cooling performance
- Improves airflow
- Reduces electricity consumption
- Eliminates unpleasant smells
- Extends equipment lifespan

7. Seal Your Home Properly
Cooling loss often occurs through:
- Open windows
- Gaps under doors
- Poor insulation
- Direct sunlight
Simple improvements such as curtains, weather strips, and closed doors help your Mitsubishi aircon cool the room faster.
8. Check Refrigerant Gas Levels
Low refrigerant gas forces the compressor to work harder.
Common symptoms include:
- Weak cooling
- Longer operating time
- Increased electricity bills
- Ice formation
Only licensed technicians should inspect and top up refrigerant gas.

If your Mitsubishi air conditioner is over 10 years old, upgrading to a newer inverter model can significantly reduce electricity consumption.
Modern Mitsubishi Electric systems feature:
- Higher energy efficiency
- 5-Tick Energy Rating
- Advanced inverter compressors
- Eco-friendly refrigerants
- Quieter operation
Professional installation also ensures optimal performance.
