What You'll Learn
Use a programmable thermostat to control the temperature
One of the most effective ways to save on electricity with AC is to use a programmable thermostat to control the temperature. Programmable thermostats allow you to set your desired temperature automatically, so you don't have to constantly adjust the settings. This is especially useful if you want to keep your house warmer when you are away and lower the temperature when you return home. By using a programmable thermostat, you can save energy and money on your cooling bills.
There are a few ways to maximize the benefits of a programmable thermostat. Firstly, it is important to properly install and maintain the thermostat by regularly cleaning or replacing filters, which can improve efficiency and reduce energy waste. Secondly, consider programming your thermostat based on peak and off-peak hours. By aligning the thermostat settings with peak occupation periods and energy costs, you can effectively regulate the temperature and AC airflow in your home, reducing energy usage and utility bills.
Additionally, you can program your thermostat to adjust the temperature when you are away from home. For example, setting the temperature one degree above your usual cooling temperature can save you up to 3% on your energy bill. This way, your AC doesn't have to work as hard to reach the desired temperature when you return. However, it is important to note that constantly adjusting the temperature may put more strain on your HVAC system, making it work harder and potentially using more energy. Therefore, it is recommended to find a comfortable ambient temperature and use the programmable thermostat to maintain that temperature.
Programmable thermostats offer flexibility in managing temperature settings based on your schedule and preferences. They can also be used in conjunction with other energy-saving features, such as smart home systems or apps, which can provide efficient control and further reduce energy consumption. By utilizing these features and keeping an eye on your energy bills, you can make adjustments as needed and optimize your energy savings.

Seal off rooms that aren't in use
Sealing off rooms that aren't in use can be an effective way to save on electricity costs when using air conditioning. By closing doors and vents, you can redirect cool air to the parts of your home that need it, avoiding unnecessary cooling of empty spaces. This strategy is particularly useful if you have a larger home or rooms that are rarely used, such as a guest bedroom.
However, it is important to consider the potential drawbacks of sealing off rooms. Some sources suggest that doing so may negatively impact your HVAC system by increasing back pressure and reducing the lifespan of the unit. Additionally, restricting airflow can lead to stale air and potential issues with mustiness, mildew, or mould, especially in hot and humid climates. To mitigate these issues, ensure there is adequate attic insulation and maintain good airflow throughout the rest of your home.
If you decide to seal off a room, there are several methods you can use. One option is to use plastic sheets and tape to cover doors and windows, creating a temporary barrier. You can also use products like Durafoam or weather stripping to seal doors and windows, filling any cracks or openings that might allow warm air to leak in. For a more permanent solution, consider installing a second door or using products like Orca and Velcro to create a sealed doorway.
Remember, the effectiveness of sealing off rooms may depend on various factors, including your climate, the design of your HVAC system, and the frequency with which you use the sealed room. It is always a good idea to consult with a professional HVAC technician or engineer to ensure that your actions do not inadvertently cause damage or reduce the efficiency of your system.
By following these suggestions, you can effectively seal off rooms that aren't in use, helping to reduce your electricity costs associated with air conditioning.

Use energy-saving modes like 'eco'
Energy-saving modes like 'eco' or 'energy saver' can significantly reduce operational costs while maintaining a pleasant environment. The key to using an air conditioner wisely is to understand your system's capabilities and tailor its use to your home's specific conditions and your lifestyle.
The Smart Eco system, for example, detects human presence and absence in a room and automatically adjusts the power settings accordingly. By avoiding unnecessary operation in unoccupied spaces, this technology helps minimize energy waste.
Programmable thermostats are another way to save energy. These thermostats require manual programming by the user or technician each time they switch between modes like heat/cooling or heating days vs. cooling days. While these were once considered “old school” technology, they remain popular among homeowners who want more control over their home environment.
Additionally, you can consider programming your AC, especially when you're away from home, to slightly increase the temperature during those periods. This means that your AC doesn't have to work as hard to reach the desired temperature when you return.
Remember, to maximize energy savings and optimize your AC usage, making optimal use of AC controls and timers is crucial.

Install window coverings to prevent heat gain
Installing window coverings is an effective way to prevent heat gain and reduce energy costs. This is because most of the heat that accumulates inside a house comes directly from sunlight shining through the windows. Therefore, it is important to install window treatments that can improve energy efficiency and block the sun's rays from heating up your home.
There are a variety of window coverings that can help prevent heat gain, such as thermal curtains or blinds. These coverings are designed to block out sunlight and provide insulation, which can help keep your home cooler in the summer and warmer in the winter. This reduces the need for air conditioning and heating systems, leading to lower energy consumption and cost savings.
When choosing window coverings, consider the direction of your windows and the amount of sunlight they receive throughout the day. For windows that receive direct sunlight, it is especially important to choose coverings that offer good insulation and sunlight blocking capabilities. This will help maximize the energy efficiency of your home.
In addition to installing window coverings, you can also seal cracks and openings around windows and doors to prevent warm air from leaking into your home. This can be done by adding caulk or weatherstripping to seal air leaks. By combining window coverings with airtight seals, you can effectively prevent heat gain and maintain a comfortable indoor temperature without relying heavily on air conditioning.
By implementing these measures, you can reduce the strain on your HVAC system, lower your energy bills, and contribute to a more sustainable environment by reducing your carbon footprint. It is a simple yet impactful way to make your home more energy-efficient and cost-effective.

Avoid heat-generating appliances during peak hours
During the hottest hours of the day, your air conditioning unit is likely to be working at maximum capacity to keep your home cool. Running heat-generating appliances simultaneously will only increase the temperature inside and place additional strain on your AC unit.
Ovens, dryers, and other heat-emitting appliances should be avoided during these peak hours. If you need to use the oven, consider cooking in bulk and preparing meals for the following days. This will reduce the frequency with which you use the oven and will also save you time on future meals.
Similarly, if you have laundry that needs to be dried, consider hanging it out to dry instead of using the dryer. This will not only save energy but also prolong the life of your clothing, as tumble dryers can cause fabrics to deteriorate faster.
If you are unable to avoid using these appliances during peak hours, there are other measures you can take to mitigate the impact on your AC unit. Ensure that the rooms in which these appliances are located are well-ventilated and that hot air is not spreading to other parts of the house. Keep the doors to these rooms closed, and consider opening windows to allow the hot air to escape.
By avoiding the use of heat-generating appliances during peak hours, you will reduce the overall temperature in your home and decrease the workload on your air conditioning unit, resulting in lower energy consumption and potential savings on your electricity bill.
