7 Tips To Use Air Conditioning Efficiently and lower you energy bills






Air conditioning is an important part of home comfort, but it can also be expensive. Fortunately, there are several ways to make your AC more efficient and lower the bills. Some of the steps will take time, but they could potentially save you hundreds of dollars in energy costs over time.

1. Change the Air Filter Every 6 Months

2. Use Smart Thermostat or AC Controllers

3. Keep Your Doors and Windows Closed

4. Set The Right Temperature

5. Use Right-Size AC For Room Size

6. Turn off the AC when you’re not home

7. Using sleep mode at night


1. Change the Air Filter Every 6 Months


The first step to using AC efficiently is checking and changing the air filter. Whether your AC has a built-in filter or you have a separate one installed on your ductwork, you should change it every six months. It's important that you use high-quality filters that are kept clean and free of debris. To ensure this, only use a dry cloth to clean the old filter and never let water or damp air touch it.


Air filters are the first line of defense against dust and dirt in your home. They can trap up to 90% of particles as small as 0.3 microns, but they need to be changed regularly for optimal performance. Replacing a clogged air filter with a new one can lower the air conditioner's energy consumption by 5 to 15 percent.


If you have pets or allergies, it’s important to keep an eye on your filter because you may need to change it more frequently than recommended. If you notice that your air conditioning isn't cooling as well as it should be, check the filter first because it could just be dirty!


2. Use Smart Thermostat or AC Controllers


Using a smart thermostat or AC controller can help you save on your energy bills. A thermostat is an electronic device that controls the temperature in a building. These days, many thermostats are connected to the internet and have features such as remote access, scheduling, and geo-fencing.


Smart Thermostats: Smart thermostats are a relatively new technology that allows for remote control of your HVAC system from your smartphone or tablet. They have many features including occupancy sensors (turn off/on when no one is home), humidity sensors (turn off A/C when humidity levels are high), Wi-Fi connectivity (you can program from anywhere), and geofencing capabilities (turn on at specific times and days).


Programmable Thermostats: Programmable thermostats require manual programming by the user or technician each time they want to switch between modes like heat/cooling, heating days vs cooling days, etc. While these were once considered “old school” technology, they still remain popular among homeowners who want more control over their home environment than just turning it on or off remotely without having to think about it with much extra effort beyond setting up an alarm clock every day.


3. Keep Your Doors and Windows Partially Open


Keeping doors and windows closed is the single most important thing you can do to keep cool, but it's also one of the hardest habits to break. When temperatures rise outside (which they tend to do in summer), it's natural for us to want to open up our homes so we can enjoy a breeze or get as much cross ventilation going as possible. However, this actually does more harm than good. As soon as you open them up, warm air will rush into your home—and will continue doing so until you close them again! Instead of opening up your doors and windows fully during warmer weather periods (or keeping them open while at work), try partially opening them instead. This way, some airflow will still pass through without creating too much chaos inside your house when things get hot outside!

4. Set The Right Temperature


The ideal temperature for your home's AC is 78 degrees. This can be set to the same as your home's, or it can be set according to body temperature—the point of which is to keep you comfortable while saving energy.


Additionally, if you're using air conditioning frequently and/or during hot summer months, it may be worth investing in an Energy Star-certified unit. These units use up to 10 percent less energy than non-certified models and are just as efficient at keeping rooms cool!


To truly master the art of 'how to use air conditioner' effectively, consider integrating smart practices that not only elevate your comfort but also optimize energy usage. Start by evaluating your air conditioner's settings and align them with the daily temperature fluctuations. By setting your AC to operate during the cooler parts of the day, you can leverage natural diurnal temperature changes to your advantage. This method, coupled with the strategic placement of your AC unit for optimal airflow, ensures that your home remains comfortable without unnecessary energy expenditure. Furthermore, the use of energy-saving modes, such as 'eco' or 'energy saver' settings, can significantly reduce the operational costs while maintaining a pleasant environment. Remember, the key to 'how to use air conditioner' wisely lies in understanding your system's capabilities and tailoring its use to your home's specific conditions and your lifestyle.


5. Use Right-Size AC For Room Size


To keep your energy bills down, you need to ensure that the AC unit is not too big for the room. Use a room calculator that will help you determine what size of AC would be best for your space. If you have multiple rooms, it could be beneficial to consider buying multiple smaller units instead of one large unit. This will allow you to use more efficient models and lower your overall electricity costs.


6. Turn off the AC when you’re not home


Turn off the AC when you’re not home. If you have a programmable thermostat, make sure to set it so that the AC turns on automatically 30 minutes before your expected return time in the evening and an hour before your expected return time in the morning. This way, the temperature of your house will be comfortable by the time you get home from work or school, and can save up to 20% on your energy bill. If possible consider using a timer switch to turn off completely when leaving for work for an extended period of time such as weekends or vacations (saving up to 40%). The TCL FreshIN series inverter air conditioner can help you achieve that easily. You can remotely operate functions via TCL Home App, or control via simple voice commands.


7. Using sleep mode at night


The air conditioner's temperature and fan speed are automatically adjusted in the SLEEP mode to make the space more pleasant at night. Up until the specified temperature of 78 degrees, the temperature will automatically increase by 1 every 30 to 60 minutes and alter a maximum of six times.




As you can see, there are a variety of things that you can do to use your air conditioning more efficiently. The most important thing is to keep an eye on your energy bills and adjust accordingly. If you follow these tips and make the necessary changes, we’re sure that your AC will be working at peak performance all summer long!
