When Your AC Dies and Help Won’t Come for Days: San Mateo County’s 2025 Emergency Cooling Plan
Summer temperatures in San Mateo County can soar into the 90s, making a functioning air conditioning system essential for safety and comfort. But what happens when your AC breaks down during a heatwave and your trusted HVAC contractor can’t reach you for several days? San Mateo County’s Department of Emergency Management coordinates countywide preparedness and response services, but when it comes to HVAC emergencies, homeowners need their own action plan.
Recognizing a True HVAC Emergency
For residential structures, an outdoor temperature of 90 degrees would be considered a temperature level to request emergency AC repair service. However, not all AC problems require immediate emergency response. If the loss of air conditioning threatens your health or causes extreme discomfort for too long, it may be an emergency.
Call for emergency service immediately if you experience:
- Electrical issues like constantly tripping circuit breakers, burning smells, or dimming lights while the AC runs
- Visible moisture collecting around your unit, which can cause electrical problems or internal damage
- AC stops working when outdoor temperature exceeds 90°F, produces burning smells, leaks water inside the house, or forms ice on the outdoor unit during summer
Immediate Steps When Your AC Fails
Before panicking, try these troubleshooting steps that might save you from needing emergency service:
- Check the thermostat – ensure it’s set to “cool” and the temperature is lower than room temperature. If battery-powered, check the batteries.
- Look at the circuit breaker – go to your electrical panel and check if the AC breaker has tripped, then try resetting it.
- Inspect the air filter – a dirty filter restricts airflow, so replace it if it looks clogged with dust and debris.
- Examine the outdoor unit – ensure it’s clear of obstructions like plants or debris and the power switch is on.
If these steps don’t work, turn off power to the AC unit at the breaker box to prevent additional damage.
Your Emergency Cooling Survival Kit
Creating an air conditioning emergency plan doesn’t need to be fancy or expensive — it just needs to keep you safe in extreme heat if you’ve lost access to air conditioning. Essential items include:
- Jugs of purified water and frozen ice packs with bottled water in the freezer
- Backup fans: handheld, window, and standing fans
- A predetermined location where household members can go if it becomes unsafe to stay home
- Consultation with doctors about temperature thresholds and heat-related illness signs for vulnerable family members and pets
Temporary Cooling Strategies While Waiting for Repairs
When professional help is days away, these strategies can help maintain livable conditions:
Create Cross-Ventilation: Open windows and use fans to push hot air out and pull cooler air in, focusing fans on yourself for direct cooling effect.
Block Heat Sources: Close blinds and curtains to block sunlight immediately. Prepare food in the microwave and wait until after dark to run the dryer and dishwasher.
DIY Evaporative Cooling: Create a temporary evaporative cooler by placing bowls of ice water in front of fans. Fill mixing bowls with ice and place them in front of table fans – the warm air will melt the ice, acting like refrigerant to cool the air.
Use Your Home’s Natural Cool Zones: If you have a basement, spend time there as it’s typically cooler. For two-story homes, have everyone sleep on the lowest level until repairs are completed.
When to Seek Alternative Shelter
If your AC breaks during a severe heatwave, consider going to a cooler or air-conditioned location while it’s being repaired, particularly important for heat-sensitive groups like babies, the elderly, immunocompromised people, and pets. San Mateo County provides cooling center resources during extreme heat events through their community services pages.
