An HVAC emergency is any heating or cooling issue that creates an immediate safety risk, risks property damage, or leaves the home without essential heat or cooling in extreme weather. Most true emergencies begin with unsafe signs like burning odors or electrical problems, or a complete loss of heat or AC when temperatures are severe. For urgent situations, we provide 24/7 Emergency Services with live answering, and our trucks are stocked to complete about 93% of repairs on the spot. We handle these situations routinely for homeowners in the Costa Mesa area. Cole Comfort Club members receive priority 24/7 service and pay the standard diagnostic instead of the $199 non-member emergency fee.
Call right away if you notice any of the following:
- No heat during freezing conditions or no cooling during extreme heat
- Burning smell, smoke, sparks, or a loud bang from the system
- Gas odor or a carbon monoxide alarm
- Repeated breaker trips or active water leaking from the air handler
If you’re unsure, turn the system off at the thermostat and breaker and request emergency service.
