Frequently Asked Questions

An HVAC emergency for homeowners is any situation that creates a safety risk, active property damage, or a loss of essential heating or cooling that cannot wait for normal business hours. The most common trigger is a furnace failure in freezing weather, which can threaten health and frozen pipes. We treat emergencies as issues that endanger people or the home; problems that only reduce comfort can usually wait. A simple rule from the field: if the system is tripping breakers, leaking water, or producing unusual odors, stop it before it hurts something. We provide 24/7 on time service, and we respond to these situations every week throughout the Sioux Falls area.

Look for these immediate-action signals:

  • No heat during a hard freeze or no cooling in extreme heat for vulnerable occupants
  • Gas smell or a carbon monoxide alarm sounding
  • Electrical burning odor, smoke, sparks, or repeatedly tripped breakers
  • Active water leaks from the furnace or AC that can damage ceilings or floors

If any of these occur, turn the system off and, if you smell gas, leave the home and call the gas utility before requesting emergency service.
