Why It Makes Sense to Set Your Thermostat Higher in Summer

During the sweltering summer months, the desire to stay as cool as possible can lead many homeowners to keep their thermostats at the coldest setting, but is this really the most effective strategy?

What is considered 'normal' varies greatly from household to household, but consistently running your air conditioning unit at a lower set point can have significant impacts on your energy usage and the health of your system.

The Cost of Cold

Let's start with the most obvious: air conditioning is an expensive utility. Reducing the temperature in your home is a surefire way to increase your electricity bill. But how does raising the temperature even a few degrees affect your energy consumption?

When your air conditioner has to work harder to bring temperatures down to a lower set point, it runs for longer periods. This extended runtime not only raises your energy costs, but also puts more wear and tear on your unit, which can lead to premature failure or the need for costly repairs.

Reducing Energy Consumption

According to energy experts, for every degree you raise your thermostat above 78°F (25.5°C) in summer and below 70°F (21°C) in winter, you can save about 3-5% on your energy bill. This is because running your AC less often can significantly lower your utility costs.

Even though the exact savings will depend on your local climate and your air conditioning equipment, making a small adjustment can have a big impact. By raising your thermostat and using a ceiling fan to circulate air, you can achieve a comfortable indoor temperature without the need for constant cooling.

The Life Expectancy of Your AC Unit

The lifespan of your air conditioning unit is critical. An AC unit can last anywhere from 10 to 20 years, but the regularity of its operation plays a significant role in determining its lifespan.

Consistently running your AC at a lower set point can shorten its life due to the increased strain on certain components. Just like any piece of machinery, frequent and prolonged use can lead to wear and tear, which can result in the need for repairs or, worse, replacement.

Therefore, setting your thermostat to a mid-range temperature during the summer can help your AC unit operate more efficiently and last longer. For many, setting it to 78°F (25.5°C) or even 80°F (26.6°C) during the day, and even higher overnight, can still provide a comfortable living environment without the heavy burden on your unit.

Conclusion and Tips

Setting your thermostat higher in the summer is a smart move that can save you money, extend the life of your air conditioning unit, and contribute to a more sustainable living environment.
