What to Do When You Lose Power and Have No AC

Losing power in the middle of a heatwave or summer storm can be more than inconvenient—it can be dangerous. If your air conditioning stops working during a power outage, it’s important to know how to stay cool, safe, and informed. Here's a step-by-step guide from PowerPlantMaps.com to help you manage the situation effectively.

🌡️ Stay Cool Without AC

  • Close blinds and curtains to block sunlight and reduce indoor temperatures.
  • Open windows during cooler hours (evening or early morning) to let fresh air circulate.
  • Stay low—heat rises, so basements or lower floors will be cooler.
  • Use battery-powered or hand fans with a wet cloth to simulate a breeze.
  • Wear light-colored, loose-fitting clothing made of cotton or linen.

💧 Stay Hydrated

Drink plenty of water—at least 8 oz every hour in hot conditions. Avoid alcohol, caffeine, or sugary drinks as they can dehydrate you. If you have power banks or ice packs, use them to cool water bottles.

🧊 Emergency Cooling Techniques

  • Wrap a wet towel around your neck or wrists to cool down your core body temperature.
  • Soak your feet in a bucket of cool water or take a sponge bath with lukewarm water.
  • If you have access to a vehicle, use its air conditioning to cool off in short intervals.

🔦 Prepare an Outage Emergency Kit

Always keep a kit ready for blackouts, especially during the summer:

  • Flashlights and extra batteries
  • Portable chargers or solar power banks
  • Battery-powered fan or cooling towels
  • Non-perishable food and bottled water
  • Manual can opener and utensils
  • Printed emergency contacts

📡 Stay Informed

Use a battery-powered or hand-crank radio to monitor emergency updates. You can also check PowerPlantMaps.com Power Outage Map for local plant failures, maintenance issues, or downed grid infrastructure near your area.

🏥 Know the Signs of Heat Illness

During a prolonged power outage, especially with no AC, heat-related illness can be a serious risk. Watch for symptoms of heat exhaustion and heatstroke:

  • Dizziness or fainting
  • Rapid heartbeat
  • Nausea or vomiting
  • Confusion or disorientation

If someone exhibits these symptoms, move them to a cooler place, apply cool compresses, and seek medical attention if symptoms worsen.

📱 Report Issues and Seek Help

Call your local utility to report the outage. Use social media, text alerts, or neighborhood networks like Nextdoor to share updates and get help from neighbors or emergency services if needed.

🧰 Long-Term Solutions

Consider investing in:

  • Backup generators (solar or fuel-based)
  • Home battery systems with solar panels
  • Reflective insulation for windows

These upgrades can help you stay safe during future power outages, especially if you live near aging or overburdened power plants or substations.
