90-degree heat on the way: Take these steps now to keep your home comfortable and manage energy use

By PR Newswire
  • What’s happening: Temperatures are forecast to reach the 90s, pushing cooling systems to run longer and use more energy to maintain indoor temperatures
  • Why it matters: Acting now with a few simple steps can help your cooling system run more efficiently during extreme heat and reduce energy use

CHARLOTTE, N.C., May 13, 2026 /PRNewswire/ — Temperatures are expected to climb into the 90s in the coming days – and with humidity, it may feel closer to 95-100°F in parts of the Carolinas. For many customers, this may be the first time cooling systems are put to the test this season, causing them to run longer to maintain indoor comfort. Warm overnight temperatures can add to the strain, keeping systems running for extended periods.

Duke Energy is encouraging customers to act now with simple steps and tools that can make a difference before the hottest days arrive – especially as spring’s dry conditions and high pollen levels may already be restricting airflow for some outdoor units.

“With humidity, it can feel closer to 100 degrees – and that puts even more demand on cooling systems,” said Max Thompson, lead energy meteorologist at Duke Energy. “If your system hasn’t been running regularly yet this season, now is the time to get it ready. Spring pollen and dust buildup can clog filters and restrict airflow, forcing your system to work harder. Changing your air filter and adjusting your thermostat are simple steps that can help your system run more efficiently when the heat really sets in.”

Start with these high-impact actions

1. Clear the way for your cooling system

  • Check and replace air filters so air can flow freely
  • Don’t wait – clogged filters force your system to work harder and use more energy
  • Clear grass, leaves and debris from around your outdoor unit

2. Schedule your free home energy assessment

  • Get expert guidance tailored to your home
  • Learn how your home uses energy and where to improve efficiency
  • Receive free energy-saving products installed during in-home assessments

This free service helps identify ways your home can perform more efficiently during periods of high heat.

3. Adjust your thermostat – and let technology help

  • Set your thermostat to the highest comfortable setting when you’re home
  • Raise it a few degrees when you’re away
  • Cooling is often the largest energy user in the home – every degree matters

Smart thermostats can help automate adjustments and make it easier to stay consistent – and now is a great time to act.
