What Is Considered an HVAC Emergency for Homeowners?

An HVAC emergency for homeowners is any heating, cooling, or ventilation failure that creates an immediate safety risk or could cause property damage. The most common trigger is losing heat during freezing weather or losing cooling during dangerous heat. Other urgent scenarios involve suspected gas or carbon monoxide, electrical hazards, or fast water leaks that can ruin ceilings or floors. Technicians in the St. Louis area handle these situations around the clock; we are Available 24/7 with emergency service calls starting at $199 plus repairs, and Preferred Partner Plan members receive half off the emergency service.

Treat it as an emergency if you notice:

• No heat in near‑freezing temps or no cooling during extreme heat
• Any smell of gas or an active carbon monoxide alarm
• Electrical burning smell, smoke, sparks, or a breaker that won’t stay set
• Active water leak from the furnace, A/C, or water heater

If you suspect gas or carbon monoxide, evacuate first and contact emergency services before calling an HVAC technician.
