Frequently Asked Questions

An HVAC emergency is any issue that threatens safety, causes active damage, or stops heating or cooling during extreme weather. Most often it’s total heat loss in cold or suspected gas, carbon monoxide, electrical, or major water problems. If you’re forcing it to run with resets, the system is protecting itself and should stay off. Cardinal Heating & Air responds 24/7 across the Greater Seattle area with trained techs and stocked service vans.

Treat it as an emergency if you notice:

  • No heat during freezing weather or no cooling in dangerous heat.
  • Gas smell, carbon monoxide alarm, or soot at fuel-burning equipment.
  • Burning odor, smoke, sparking, or breakers tripping again after reset.
  • Active water leak from a boiler, water heater, or indoor unit.

If you suspect gas or electrical danger, shut the system off, get to safety, and call a pro.
