When your AC fails in Fullerton during a summer heat wave, it’s a real emergency. Fullerton’s inland temperatures regularly reach 100°F+ in July and August, and a home without air conditioning in that heat can become dangerous within hours — particularly for elderly residents, infants, and anyone with medical conditions. Here’s what to do when your Fullerton AC fails in summer heat.
Pulse Heating and Air provides emergency AC service in Fullerton with same-day response. Call (714) 908-3868 directly — don’t use a contact form for urgent situations.
Immediate Steps When Your Fullerton AC Fails
Call (714) 908-3868 First
Don’t wait. Don’t try to troubleshoot extensively in 100°F heat. Call immediately. Maintenance plan members receive priority scheduling — typically same-day even during peak August demand. Non-plan members get same-day service when schedule allows.
Protect Vulnerable Household Members
Move elderly family members, infants, and pets to the coolest room in the house or to a cooled space (neighbor, library, mall) if temperatures are extreme. Lower blinds and curtains. Run ceiling fans to maintain air movement.
Quick Checks Before the Technician Arrives
Thermostat on Cool mode with setpoint below room temperature, batteries fresh. Both circuit breakers on (indoor and outdoor units each have a breaker). Filter not completely blocked. If the outdoor unit hums without the fan spinning, don’t repeatedly try to start it — capacitor failure damages the motor on restart attempts.
