The Best Summer Thermostat Settings for Comfort and Energy Savings

With the arrival of summer, keeping your home cool without sacrificing energy savings can be a challenge. Warmer temperatures, occasional humidity, and rising utility costs make it important to find the right thermostat setting for both comfort and efficiency. Here’s how to maximize cooling, minimize expenses, and keep your air conditioning system performing at its best.

What’s the Ideal Summer Thermostat Setting?

According to guidance from the U.S. Department of Energy and leading HVAC manufacturers, 78°F is often considered the ideal balance between comfort and energy efficiency during the summer when you’re at home. This setting provides effective cooling while helping control energy consumption, particularly during the hottest parts of the day.

If you’re accustomed to cooler indoor temperatures, try increasing your thermostat by one or two degrees at a time until you find a comfortable setting. For every degree above 72°F, you may reduce your cooling costs by up to 3%. This gradual adjustment is especially helpful for households with different comfort preferences.

Adjusting the Thermostat When You’re Away

There’s no reason to cool an empty home, but it’s also not recommended to turn your air conditioner off completely during periods of hot weather. Instead, use a programmable or smart thermostat to raise the indoor temperature by 7 to 10 degrees while you’re away at work or out for extended periods. For many homes, setting the thermostat to 85°F while away can help reduce monthly energy costs.

A smart thermostat makes these adjustments simple by allowing you to schedule temperature changes or control your system remotely. Many homeowners have found that upgrading to a smart thermostat makes it much easier to improve comfort while managing energy costs.

Tips to Enhance Comfort Without Overworking Your AC

Adjusting the thermostat is only one part of improving your home’s comfort and efficiency. You can also:

• Keep blinds or curtains closed during the hottest part of the day to reduce heat gain.

• Run ceiling fans in the counterclockwise direction to create a cooling breeze that can make a room feel several degrees cooler.

• Avoid using heat-producing appliances, such as ovens and dryers, during the hottest hours of the day.

• Seal air leaks and improve insulation to reduce the workload on your cooling system.

Additional improvements, such as replacing worn weatherstripping, taking advantage of cooler evening temperatures for natural ventilation, and installing a whole-home dehumidifier, can further improve comfort while reducing energy use.

Regular Maintenance Goes a Long Way

Every HVAC professional knows that regular maintenance is essential for reliable summer performance. Dirty air filters, blocked vents, and low refrigerant levels can force your air conditioner to work harder while reducing its efficiency. If your system struggles to maintain the desired temperature or cycles on and off frequently, it may be time to recharge central AC or have a technician inspect the system for leaks.

A seasonal tune-up that includes cleaning, refrigerant checks, and airflow testing helps keep your system operating efficiently. Routine maintenance from Kemnitz Air Conditioning & Heating Inc. can also reduce the likelihood of unexpected breakdowns, extend the lifespan of your equipment, and minimize the need for emergency AC repair.

When It’s Time to Upgrade

If your air conditioner is more than 10 to 12 years old or requires frequent repairs, it may be time to consider a more energy-efficient replacement. Modern systems with higher SEER2 ratings, variable-speed technology, and improved humidity control can provide greater comfort while significantly reducing monthly energy consumption. Available rebates and utility incentives may also help offset the cost of upgrading.
