The heat is here to stay this week and will likely slide into next week.

Philadelphia is set for its first heat wave of the year by Thursday, but the hottest day of the week will likely be Friday at 97 degrees.

Remember to stay prepared as those hot days settle in this week:

  • Slow down
  • Stay in air conditioning
  • Weather lightweight clothing
  • Close curtains and blinds
  • Drink plenty of water
  • Take care of the elderly, small children and pets

Philadelphia heat wave: How to prepare as dangerous heat expected to grip region

From pools and cooling centers to what to wear and pet care, here's everything you need to know about preparing for the upcoming heat wave in Philadelphia and its surrounding areas, including how to spot heat-related illnesses.

During the heat wave, service calls for air conditioning are expected to jump.

Mike Seymour, owner of HTR Mechanical, explains how regular maintenance with a contractor will keep your system running.

"I usually tell them, set it where it’s comfortable and try not to open and close the door a lot," Seymour said. "If you have young kids or a dog going in and out of the house, pull the blinds down. As long as your filter is clean, the unit is sized accordingly or right for the house and you block the sun coming in as much as possible, you should be okay."
