Understanding Bay Area Heat Waves
Climate change has increased heat wave frequency and intensity. Areas that rarely needed AC are now seeing 90-100°F days multiple times per summer.
Maximizing Your AC During Extreme Heat
Pre-cool your home in the morning when temperatures are lower. Close blinds, seal gaps, and avoid heat-generating activities like cooking or laundry during peak hours.
What To Do If Your AC Fails
Keep ice and fans on hand. Go to a cooling center if temperatures become dangerous. For seniors and those with health conditions, have an emergency plan.
Protecting Your Equipment
Shade your outdoor unit if possible. Don't set the thermostat more than 20°F below outdoor temperature—this strains the system without improving comfort.
When to Call for Emergency Service
If your AC isn't cooling, makes unusual sounds, or trips breakers repeatedly, call for service immediately during a heat wave. Don't wait—emergency slots fill quickly.
