Split air conditioners They have greater energy efficiency than either window or portable A/Cs.
A 5 star AC offers superior energy efficiency, leading to lower electricity bills, while a 3 star AC is more budget-friendly but tends to consume slightly more power. If you're undecided on whether to go for a 5 star or 3 star AC, consider factors like long-term energy savings and initial costs.
Use Sleep Mode or Timer
Many AC units come with a sleep mode or timer feature, allowing you to set a specific duration for the AC to run before shutting off automatically. According to the International Energy Agency, using these features can save up to 30% of the energy consumed by an air conditioner .
Ductless/Mini-Split systems.
Ductless units are considered the most energy-efficient air conditioning systems on the market.
You can also reduce your energy costs significantly by raising the temperature while you are at work, away from home, or asleep. For the greatest savings, consider setting your thermostat to: About 78 degrees while you are at home. About 82 degrees while you are sleeping.
Setting your air conditioning to 72°F is generally considered a comfortable indoor temperature for many people. It strikes a good balance between comfort and energy efficiency, making it a popular choice for residential settings.
The GE Profile 10,000 BTU window air conditioner has the best Energy Star efficiency score of any window unit. This is measured with the Combined Energy Efficiency Ratio (CEER). If saving on your electricity bill and being more sustainable are important, this is the one.

The ideal temperature for your AC depends on several factors. In general, it's recommended to keep your thermostat between 24°C (75°F) and 26°C (78°F) for a good balance between comfort and energy efficiency. Setting your AC lower won't cool the room much more but will make it run harder and cost you more money.
AUTO is significantly more energy efficient between the two modes since the fan is only running when your AC is going through its cooling cycle. This takes less power, which is more budget-friendly, with some estimates showing you can save as much as $50 per month just by keeping your AC on AUTO.
Your aircon has a lot of features that you are probably not aware of. Running your aircon in economy mode will make your compressor run slower, which means the unit will consume less energy. This feature comes in handy if you are using your aircon for long periods of time.
The Best AC Temperature to Save Money
The right thermostat setting is very important for summer AC use, but that setting may be higher than you would think. The best AC temperature to keep your thermostat set at over the summer is 78 degrees.
As compared to a normal air conditioner, an inverter AC offers better, more consistent cooling. Inverter ACs are also more energy-efficient and quieter too. This is because in a non-inverter AC, the compressor switches on and off several times to regulate the temperature.
For older homes and those where it isn't possible to install ductwork — ductless systems are considered the ideal choice. They are considered the most energy-efficient air conditioning systems on the market. Also, they can be installed in almost any house because they do not require expensive ductwork.
Increase the thermostat
If you are just as comfortable with your thermostat one or two degrees higher than you currently have it set, go ahead and turn it up. Even a one degree difference will have an impact on your energy bill. Many recommend 78 degrees as a good temperature for air conditioners to run efficiently.
Split systems: These are generally cheaper to run and suited for single rooms or open-plan areas. Ducted systems: These are more expensive to operate but ideal for whole-home cooling. Window units: They are cheaper to purchase but less efficient to run than split systems.
Your air conditioning system is one of the biggest culprits behind skyrocketing electric bills. When your air filter is dirty, refrigerant levels are low, your thermostat is faulty or you lack proper maintenance, your A/C system can end up using a lot more energy than it should.
A more moderate setting like 24°C (75.2°F) can achieve comfort with reduced electricity usage.
