How Can I Set the Right Indoor Temperature on My Air Conditioner or Heater?

For many, finding the right temperature for an indoor space is a balance between comfort and affordability. Air conditioning experts estimate an approximate six to eight percent in energy savings for every degree higher you set the thermostat in the summer months.

Similarly, lowering the thermostat by 10 to 15 degrees for 8 hours or more per day has been shown to reduce heating costs 5 to 15 percent per year. These temperature variances reduce the amount of energy required by the HVAC system to produce and maintain the temperature, resulting in an overall lower energy footprint.

However, studies have shown the highest level of comfort for waking hours occurs when ambient room temperature ranges between 73-78 degrees Fahrenheit in the summer and 68-74 degrees during winter.

According to information from H. Craig Heller, PhD, professor of biology at Stanford University, ideal temperatures for sleeping areas differ from waking temperatures as the temperature your brain is attempting to achieve goes down. While sleeping preferences differ by person, the typical recommendation is to keep the room between 65 and 72 degrees Fahrenheit.

These preferred temperatures may not be the best recommendations for those with their eyes on energy savings, where the general rule is to keep temperatures as high (in summer) and low (in winter) as physically possible. Fortunately, there is a level of compromise.

Keeping air conditioning and heating systems at optimal temperature levels can be offset by raising or lowering the ambient temperature standards while people are away. For businesses, keeping a more comfortable waking environment throughout working hours and raising or dropping the temperature for nights and weekends could be the answer. For homes, standard ambient and sleeping temperatures can be observed based on the habits of the residents.

Investing in a programmable thermostat can make maintaining these temperature plans simpler. In addition, make certain to install the thermostat away from heating or cooling registers, appliances, lighting, doorways, fireplaces, skylights, windows and other areas that receive direct sunlight or drafts. Remember to change your thermostat batteries once per year.
