What Temperature To Set The Air Conditioner When Away in Summer?

5 minute read

To save energy and money, the temperature you set your air conditioner at while you're away in the summer is crucial. Optimizing your AC settings ensures you use what you need and can save you a lot of money on your utility bills. Plus, the correct temperature will ensure that in your savings, you also keep the indoor environment safe and healthy enough for your pets, plants, or other sensitive items at home. These considerations balance out in just the right way to create a comfortable yet economical home during the hot summer months.

General Recommendations

Energy experts usually recommend setting your air conditioner at about 78-80 degrees Fahrenheit when the house is unoccupied during the summer. This range is the best temperature because it reduces the load on your air conditioning unit. As a result, it minimizes the energy consumed while preventing the indoor climate from getting too hot and humid. These settings help maintain a balance between energy efficiency and the protection of your home's interior and belongings from heat-related damage.

Considerations for Pets

If you have pets at home, it's important to adjust these temperature recommendations to ensure their safety and comfort. Indoor temperatures should not exceed 78 degrees Fahrenheit for pets. Always make sure enough water is available, and consider areas in the house where pets can comfortably stay cool without needing to lower the temperatures in the entire home.

Impact on Humidity and Air Quality

The temperature setting in your air conditioner significantly affects indoor humidity levels and overall air quality. A slightly higher temperature setting, say 78 degrees Fahrenheit, dehumidifies the air since the air conditioner will be working at a speed that is efficient enough to remove moisture without straining the system. It is a critical balance, considering high humidity can result in mold and mildew formation, which is damaging both to the home structure and its occupants. Proper management of temperature and humidity levels ensures a healthier living environment and enhances the durability of your home.

Programmable Thermostats and Smart AC Controllers

Programmable thermostats and smart AC controllers are two necessary tools to manage your home's climate efficiently. These gadgets let you set different temperatures at different times of the day or week so that your home temperature automatically adjusts as you program it. This simply means that your air conditioning system operates less intensively when nobody is at home and cools your space just before you arrive to ensure both comfort and efficiency without manual intervention.

Smart Thermostats

Smart thermostats offer the next level of home climate management. These advanced devices have a few principal advantages:

  • Remote Control: Most smart thermostats can be controlled through smartphone apps, which enable you to adjust your home's temperature from anywhere. This is useful in case you forget to change the setting before leaving home.
  • Learning Capabilities: Over time, smart thermostats can learn your schedule and preferences, automatically adjusting the settings for your comfort and optimize energy use without your direct input.
  • Energy Usage Reports: Many smart thermostats also provide detailed reports of energy consumption and recommend ways to improve energy efficiency.

Tips on How to Use Technology Efficiently

To get maximum benefits from these technological aids, consider the following tips:

  • Proper Placement: Place your thermostat away from direct sunlight, drafts, doorways, windows, and room corners. Proper placement helps prevent false readings and ensures your AC operates on the actual ambient temperature of the central living areas of the house.
  • Regular Updates: Keep the thermostat software up to date so that you enjoy the latest features and efficiency improvements.
  • Away Features: Use the 'away' features on smart thermostats, which let you set a higher temperature while nobody is home and program it to cool down the house half an hour before you get back.
  • Integrate with Other Smart Home Devices: For added efficiency, integrate your smart thermostat with other smart home systems, like lighting and blinds. For example, automatically lowering the blinds at the hottest time of day can decrease the cooling load on your air conditioner.

By utilizing these technological helpers, you can drastically improve your home's energy efficiency, lower your costs, and maintain a comfortable indoor environment with minimal manual effort involved.

Advantages of Proper Temperature Management

Proper temperature management of your air conditioner can save you significant money on your energy bills. If you set your AC to recommended temperatures when you're out, and if you use technology like programmable or smart thermostats, you will save from cooling an empty house unnecessarily. That means your air conditioning unit will be used only when needed and at its most efficient rate, using less energy. For instance, raising the thermostat setting by just a few degrees when no one is home can decrease your cooling costs by up to 10%, according to the U.S. Department of Energy. Those savings add up quickly during a long, hot summer, which reduces your monthly utility bills while still keeping you comfortable in your home.

Environmental Impact

Saving money on air conditioning also has a positive effect on the environment. Using less electricity reduces the strain on the grid, which often runs on fossil fuels. You help reduce carbon emissions and other pollutants from the production of electricity when you require less. Not only that, but efficient energy use can also contribute to lessening the heat island effect in cities where large-scale AC use can raise ambient temperatures. AC, in general, reduces energy consumption and adds to the broader goals of reducing greenhouse gas emissions and promoting a healthier planet in general.

Common Misconceptions and Mistakes

One of the big myths about managing air conditioning when away is that turning it off ultimately saves the most energy and money. While it seems intuitive that the most significant savings come from not using the AC at all, this approach actually backfires during serious heat waves. Turning off the air conditioner can lead to highly high indoor temperatures, damaging not only the home's structure and interiors (wood, electronics, and appliances) but also leaving a massive energy demand when the system is finally turned back on and works hard to cool down the overheated space. In this scenario, the energy used could be much higher than if it had been set to a moderate, higher temperature.

Common Mistakes Homeowners Make

  • Setting the Thermostat Too Low on Return: Some homeowners turn the temperature way down when they return home with the hope of cooling it faster. However, air conditioners can only cool at one speed, and setting the temperature too low can lead to overcooling and unnecessary expenses.
  • Neglecting AC Maintenance: Failure to check and replace air filters or to ignore the annual maintenance check causes the AC system to work inefficiently. Poor maintenance often results in reduced airflow and system efficiency, raising energy costs and reducing the unit's service life.
  • Ignoring Humidity Control: In high-humidity regions, merely lowering the temperature may not provide comfort. Ignoring the dehumidifying capability of air conditioning systems can lead to a muggy indoor environment and the mold and mildew issues discussed earlier.
  • Overcooling Unused Rooms: Some people cool the whole house, including unused rooms. Using zone cooling or closing vents in unused rooms can save a tremendous amount of cooling costs.

Knowing these common mistakes and misconceptions is, therefore, important for homeowners who want to use their air conditioning units effectively, save money, and keep themselves comfortable while protecting their house environment.

An optimum air conditioning setting in the summer when you are away will not only assure you of energy efficiency but also protect your house and cut costs. Knowing the correct settings and how they can be used with technology like smart thermostats will help one create a perfect environment for their pet or sensitive stuff left inside the house. This paper explains that a slight change in your AC setting can pay off by saving costs, which will also be friendly to the environment. Embrace such practices to better the management of energy in your house and, therefore, contribute to a greener, sustainable lifestyle.
