Recirculating air, especially on a hot day, puts less stress on your car's blower motor and air compressor, improving efficiency. Use recirculation mode to help your AC system work more efficiently to cool your vehicle down by keeping hot outside air from moving through the unit.
The best setting is high cool. That will give you the most cooling the unit can produce.
Use Recirculation Mode
Recirculation mode pulls air from inside the car instead of taking in outside air. This is especially helpful if you drive in stop-and-go traffic on a hot day. It does not put as much strain on your system as direct cooling does.
As a rule of thumb, when the ambient air temperatures 70° degrees Fahrenheit (21° Celsius) and humidity 20%, the AC outlet air temperature should be in the 35°-40° degrees Fahrenheit range.
If you're looking for recommendations, try B Mode for city driving and D Mode for highway driving.
Use recirculation mode to help your AC system work more efficiently to cool your vehicle down by keeping hot outside air from moving through the unit. Recirculating cooled air, rather than bringing in fresh outside air, can cool down your vehicle faster.
Comfort Mode
In other words, it'll give you that “floating-down-the-highway-on-clouds” kind of feeling.
The Best Temperature for Reducing Energy Usage
The U.S. Department of Energy recommends setting your thermostat to 78°F for a balance of comfort and savings. Smart thermostats can further optimize cooling, letting you increase temperatures while away and automatically cool the house when you return.
There are benefits to having your air conditioner set to “auto” and “on.” The benefits of the “auto” setting include higher efficiency, lower energy bills, better humidity control, less wear and tear on some components, and quieter running.
In the summer, experts say the thermostat for your air conditioner should be set to at least 78°F during the day when people are at home. That setting is designed to help people avoid high energy bills in the summer. The lower your thermostat setting, the higher your bill.
In the air recirculation mode, the car's air conditioning system recirculates the air inside the vehicle for cooling. Selecting the fresh air mode brings in outside air into the car by opening an air duct in the front of the vehicle. Both these modes have their advantages and disadvantages.
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.
Auto mode is similar to cool mode as the AC unit will work to cool the air down. However, unlike cool mode, once the room reaches the set temperature, both the compressor and fan switch off. This mode is another ideal mode for saving energy and money as once everything is switched off no electricity is used.
Set your air conditioning to the highest level that's comfortable. Turning our attention to the air conditioning unit itself, the most energy efficient action is to set the temperature to the highest value that's still comfortable (26°C during the day and 22°C when sleeping is often recommended).
WHAT IS THE BEST MODE FOR AC IN SUMMER? In summer, the best mode for your air conditioner is the "Cool" mode, set to a comfortable temperature around 78°F when you're home. This setting efficiently reduces indoor humidity and maintains a comfortable environment without overworking the AC system.
Cool mode: Ideal for hot days, this mode reduces the room temperature to your desired setting. Dry mode: Perfect for humid conditions, this mode removes excess moisture from the air without significantly reducing the temperature.
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.
For example, if it's 70°F (21°C), the A/C should be 35°F to 40°F (1.6°C to 4.4°C). Similarly, if the temperature outside is 80 degrees Fahrenheit (27 degrees Celsius), the air coming out of the air conditioner should be between 45 and 50 degrees Fahrenheit (7.2 to 10 degrees Celsius).
The recommended rule of thumb for summertime is to set the temperature to 78 degrees Fahrenheit when you're home and higher when you're away. In general, set it to 82 degrees Fahrenheit when you're asleep and 85 degrees Fahrenheit when you're away.
Eco mode helps drivers maximize fuel efficiency. This is done primarily by keeping engine revs low through different transmission shift points and softer throttle response, and it can also limit the effectiveness of the climate control system to further reduce added strain on the engine.
Eco mode - ensures the car is in its most fuel efficient configuration. Comfort mode - makes the car as comfortable as possible. Sport mode - puts the car in a more aggressive setting, usually enhancing throttle response, whilst in some cars can alter suspension, gearbox and exhaust too.
Normal: Normal mode is the standard, offering regular everyday performance, driving dynamics are not altered. The vehicle will default to Normal mode every time the engine is restarted. Eco: To maximize your range, Eco mode modifies the engine trim, reducing fuel consumption.
