Emergency HVAC: what to do right now

Some failures can wait until morning. Others can't. Here's how to tell the difference and stay safe in the meantime.

Emergency HVAC: what to do right now
Gas smell or carbon monoxide alarm: leave the home immediately, don't operate switches or phones inside, and call 911 or your gas utility from outside.

Usually an emergency

  • No heat when outdoor temperatures are near or below freezing (risk of frozen pipes)
  • No cooling during extreme heat with infants, older adults or medically vulnerable people at home
  • Burning smells, smoke, or sparking from equipment
  • Water leaking onto ceilings or electrical equipment

While you wait

  • No heat: close blinds at night, use safe space heaters (never a gas oven or grill indoors), and let faucets drip to protect pipes.
  • No AC: close blinds, use fans, stay hydrated, and move to the lowest floor or a public cooling center if needed.

After-hours pricing

Expect to pay a premium for nights, weekends and holidays, often 1.5–2 times normal rates or a flat surcharge of $100–$300. If the home is safe, a next-morning appointment may save money.

Frequently asked questions

Is no AC an emergency?

It can be during extreme heat, especially for vulnerable people. Heat illness is serious. If the home is dangerously hot, go to a cooler place while you wait.
