When to Call for Emergency Help in East St. Louis
East St. Louis families and businesses can use the emergency call or text options when a heating or cooling breakdown creates an urgent comfort concern.
An emergency can include a complete loss of heating during dangerous cold, loss of cooling during severe heat, smoke or a burning smell from HVAC equipment, water threatening property, or a commercial issue affecting customers, staff, or operations. A system problem can be urgent without being a life-safety event; when in doubt, call or text us so we can help you decide the right next step.
Gas, carbon monoxide, smoke, or fire concerns
Leave the building and call 911 or the appropriate emergency service from a safe location. Do not operate electrical switches or attempt a repair. The U.S. Consumer Product Safety Commission urges yearly professional inspection of fuel-burning home heating equipment to help prevent carbon-monoxide incidents.
