AC Temperature In Summer: How to Stay Cool and Save Energy


Many of us will use our air conditioners as the summer months draw near to keep our homes and places of employment relaxed and comfortable. However, it’s critical to consider what AC temperature in summer for maximum comfort and efficiency, given rising energy costs and worries about the environmental effects of excessive energy consumption. 

In this article, we’ll examine the elements to consider when choosing the ideal range for energy efficiency and individual comfort when choosing the temperature for your air conditioner during the summer. We’ll also review ideas and tactics for cooling your house without using your air conditioner.

What Are the Recommended Home Temperatures In Summer?

Striking a balance between energy efficiency and personal comfort is crucial when deciding what temperature your air conditioner should be set during the summer. There needs to be a universally applicable solution to this problem. Still, you can follow some general recommendations to ensure your air conditioner operates as effectively and efficiently as possible.

The ideal temperature range for air conditioning is typically between 72 and 78 degrees Fahrenheit, so that must be understood first and foremost. You can expect to feel comfortable and relaxed within this range while minimizing energy use and costs. However, this range may change depending on your personal preferences and the specific characteristics of your living or working space.

For instance, if you reside in a particularly humid area, you might find that lowering the temperature on your air conditioner to a level within this range aids in managing excess moisture and preventing mould growth.

Similarly, you should reduce your air conditioner temperature range to feel comfortable and avoid overheating if you have medical conditions that make it challenging to tolerate heat.

It’s also important to remember that the capacity and size of your air conditioner can significantly influence the suitable temperature range for your space. To achieve the desired comfort level, you might need to lower the temperature if your air conditioner is too small for your living or working space.

On the other hand, if your air conditioner is too big, it might frequently cycle on and off, saving energy and increasing costs.

You can use a few other strategies to maximize the efficiency and effectiveness of your air conditioner and adjust the temperature to the ideal range. For instance, you might want to consider utilizing a programmable thermostat, which enables you to set various temperatures for various times or days of the week. Decreasing the time your air conditioner runs when it’s unnecessary can help you save energy and money.

Additionally, consider using portable or ceiling fans to help circulate air and lessen the load on your air conditioner. Using fans with your air conditioner can create a more comfortable and efficient living or working environment while saving energy costs.

Understanding the ideal temperature range for air conditioning is a crucial first step toward maximizing your efficiency and comfort during the summer. You can find the temperature that works best for you while minimizing your environmental impact and energy costs by considering your individual preferences, the unique features of your space, and the capacity of your air conditioning unit.

Factors To Consider When Choosing AC temperature in summer:

Factors To Consider When Choosing The Right Temperature For Your Space

There are several things to consider when deciding what temperature to set for your air conditioner during the summer months to ensure you achieve the ideal balance of comfort and energy efficiency. When choosing the appropriate temperature for your space, bear the following essential considerations in mind:

  1. Humidity levels: It’s necessary to consider the humidity levels in your area when setting the temperature on your air conditioning unit because high humidity levels can make a room feel warmer than it is. Generally, comfort and indoor air quality are considered best at a humidity level of about 50%.
  2. Size of the area: When determining the ideal temperature for your air conditioner, the size of your living or working space is crucial. A larger unit will be needed to provide the best comfort levels in a larger area, which might need to be set at a lower temperature.
  3. Insulation: Maintaining a constant temperature in your living or working space depends on sound insulation. You might need to lower the temperature on your air conditioner to compensate for heat gain or loss if your area is poorly insulated.
  4. Sun exposure: You may need to adjust the temperature of your air conditioner depending on how much sun your space receives. If your room gets a lot of direct sunlight, you might need to lower the temperature on your air conditioner to keep it cool.
  5. Personal preferences: Ultimately, the temperature you set your air conditioner at should largely depend on your comfort. When deciding on the ideal temperature for your space, it’s important to remember that some people prefer a cooler temperature than others.

Additionally, it’s crucial to remember that the temperature you set your air conditioner to will impact your energy costs. By lowering the temperature on your thermostat by 7 to 10 degrees for eight hours each day, you can reduce your cooling costs by up to 10% annually.

A programmable thermostat can be used to accomplish this automatically, which can be a practical way to control your energy costs while maintaining the best possible comfort levels. 

Tips For Maintaining Comfort In Your Home Without Relying Too Much On AC:

While air conditioning is a fantastic way to keep your house cool during the sweltering summer, it can also be costly and hurt the environment. The following advice will help you keep your house cool without using your air conditioner too frequently:

  1. Use natural ventilation: By opening windows and doors, you can help the air in your home circulate and bring in fresh, cool air. This can be especially useful when it’s cooler outside, like early morning or late at night.
  2. Use blinds or curtains: Closing blinds or curtains can help keep sunlight out of your home and keep it from heating up too much during the day. For windows facing south and west, this method may be beneficial.
  3. Utilise fans: Using portable or ceiling fans can help to circulate air and create a cooler, more comfortable environment. Using natural ventilation in addition to this can be incredibly effective.
  4. Plant trees or install shading structures: Planting trees or erecting systems that block direct sunlight from entering your home, such as awnings or pergolas, can help you save money on air conditioning.
  5. Use energy-efficient lighting: Incandescent light bulbs give off a lot of heat, which can contribute to a warmer indoor environment. Switching to energy-efficient lighting options, like LED bulbs, can help lower heat output and maintain a cooler indoor environment.
  6. Cook outside: To prevent overheating your home, think about using an outdoor grill or cooktop instead of cooking inside.
  7. Insulate your home: Good insulation will help keep your house warm in the winter and cool in the summer. Your air conditioner may need to run for less time, saving you money and energy.
  8. Utilize a programmable thermostat: With the help of a programmable thermostat, you can set various temperatures for various times of the day, cutting down on the time your air conditioner needs to run when you don’t need it.


To sum up, controlling the temperature of your air conditioner during the summer can help you stay comfortable while also keeping an eye on your energy costs. You can determine the ideal AC temperature in summer for your living or working environment by considering humidity levels, space size, insulation, sun exposure, and personal preferences.

Additionally, you can employ several methods—including natural ventilation, shading equipment, and energy-efficient lighting—to keep your house cool without overly depending on your air conditioner. 

You can create a cosy living space while lessening your impact on the environment and energy costs by combining these methods and using a programmable thermostat. With these tips, you can stay relaxed and comfortable all summer while being mindful of your energy use.
