Heat Wave Survival Guide
Summer Guide for Bay Area Homeowners
Bay Area heat waves are becoming more intense and frequent. When temperatures soar into the 100s, your AC works overtime. Here's how to stay cool, protect your equipment, and survive the heat.
Pre-Cool Your Home
Run AC heavily in the morning when it's cooler and electricity is cheaper. Your home will stay cooler longer through the afternoon peak. Set to 76-78°F before heat hits.
Close Blinds and Curtains
Solar heat gain through windows can overwhelm your AC. Close coverings on sun-facing windows, especially in the afternoon. Blackout curtains are most effective.
Don't Overwork Your AC
Setting the thermostat to 65°F won't cool faster - your AC runs at one speed. It just runs longer and may freeze up. Set a realistic temperature and be patient.
Use Fans Strategically
Ceiling fans and portable fans let you feel 4-6°F cooler without lowering the thermostat. Direct airflow where people are, not empty rooms.
Reduce Internal Heat
Avoid using the oven, minimize lighting, and run heat-generating appliances (dishwasher, dryer) in the evening. Every bit of internal heat adds to your AC's burden.
Know Your Limits
If your AC can't keep up during extreme heat, that's normal. Systems are sized for typical conditions, not once-a-year extremes. Focus on keeping bedrooms comfortable for sleep.
