Emergency Preparedness

What to do when your heat or AC goes down — safety steps, temporary fixes, and when to call for emergency service.

If your heat or AC fails, check the thermostat and breaker first. For a gas furnace, shut off the gas and open windows if you smell sulfur. These guides cover the safety steps to take immediately and when a breakdown qualifies as a true emergency requiring same-day service.

What To Do When Your System Fails

  • Check your thermostat first

    Confirm it's set correctly and has power. A dead battery or wrong mode causes more "no heat/no AC" calls than an actual equipment failure.

  • Check your breaker panel

    A tripped breaker is the most common cause of a completely dead system. Reset it once — if it trips again immediately, stop and call for service.

  • Smell gas? Leave immediately

    If you smell sulfur or rotten eggs near a gas furnace, leave the house right away, don't flip any switches, and call your gas utility from outside before calling us.

  • No heat in freezing weather

    Open cabinet doors under sinks near exterior walls to help protect pipes from freezing while you wait for service.

  • No AC during extreme heat

    Close blinds, run fans to circulate air, and stay hydrated — this matters most for infants, older adults, and anyone with a health condition.

  • Know when it's a true emergency

    No heat below freezing, no AC during a heat advisory, a gas odor, or a carbon monoxide alarm all call for same-day service. A single warm room or a minor new noise can usually wait for the next business day.
