Mitsubishi Aircon Power Consumption

Currently the most popular air conditioner brand in Singapore, Mitsubishi aircon already has some available NEA-approved 5-tick rated AC models that you can consider if you have been looking to invest in highly energy-efficient air conditioning systems for your renovated HDB flat or condominium unit. And, aside from general troubleshooting for Mitsubishi aircon troubles such as the growing inability of the AC unit to blow cold air, it might also interest you to know the ins and outs of your Mitsubishi aircon power consumption, and most importantly the things you can do to minimize your AC’s energy consumption.

What’s your Mitsubishi Aircon Power Consumption

Depending, of course, on the model and BTU capacity, a Mitsubishi system 3 aircon power consumption is approximately 2.5 and 3.5 kW per hour of energy. On average, the Mitsubishi aircon power consumption is 0.8 to 1.5 kW per hour. To calculate the cost of your aircon’s electricity consumption, you may refer to the adjusted rates from the Energy Market Authority (EMA) of Singapore. According to the EMA, “from October to December 2024, the tariff rate is 29.10 cents/kWh (without GST), or 31.72 cents/kWh (with GST). ”

To more efficiently estimate the power consumption of your air conditioning unit, use the corresponding cooling capacities associated with the configuration of your air conditioning system. If you decide to go with Silverback Aircon for your Mitsubishi aircon package deal, you can find the BTU capacity of your air conditioning system on these pages:

• Mitsubishi aircon system 1
• Mitsubishi aircon system 2
• Mitsubishi aircon system 3
• Mitsubishi aircon system 4

1 kW is equivalent to 3412.142 BTU/hr. To convert BTU/hr to kWh, multiply by 0.000293. Then multiply the resulting figure with the current cost of electricity per kWh.

Minimizing your aircon power consumption

Here are several proven ways to maintain your Mitsubishi aircon’s optimal cooling performance, which is directly tied to minimizing the electricity usage of your air conditioning unit.

Things you can do at home

• Keep the air conditioned room well insulated at all times. Seal all wall gaps with a suitable sealant. For window gaps, you may use foam insulation. Preventing cool indoor air from mixing with outdoor air assists the operation of your air conditioner. A well insulated room keeps your AC from overworking where it draws more electricity than is necessary to cool a room. 
• Block sunlight with solar window films, heavy drapes, and black-out curtains. Sunlight, if it penetrates a room, can easily drive up the indoor air temperature, which is something you want to prevent if you want to save electricity while using the air conditioner.
• Use low-wattage fans to circulate air conditioned air across the room. You can also run a ceiling fan to more efficiently accomplish this. Using fans to circulate cool air means you can set your air conditioner to a higher temperature and still remain comfortable. Fans are in fact very effective in evenly distributing cool air to the different parts of a room, something you can leverage as an energy cost-cutting measure. 

Things you can set for your aircon

• Always use the AC timer settings to more conveniently cut your energy consumption. Your aircon has a sleep mode and other energy-saving functionalities, which you can use for your convenience.
• Stick to a pre-set thermostat setting of 25 or 26 degrees Celsius. You actually won’t feel that much difference in terms of the level of comfort. Also, try to avoid changing the thermostat settings frequently. Lowering the temperature actually won’t make that much difference to make the air conditioner cool the room faster. It will just make it harder–and even longer–for the AC to reach and maintain your frequently adjusted lower temperature setting, which means more and more energy is consumed by the air conditioning unit.
