It's 90 degrees in New Lenox and your air conditioner just stopped working. Here's exactly what to do — step by step — to stay safe and get your AC fixed as fast as possible.

Step 1: Check the Basics (5 Minutes)

Before calling for service, check these quick items — they resolve about 20% of "broken AC" calls:

  • Thermostat: Is it set to "Cool" and set below the current room temperature? Is the fan on "Auto"?
  • Air filter: A severely clogged filter can cause the system to shut down on a safety limit. Replace it.
  • Circuit breaker: Check your electrical panel for a tripped breaker labeled "AC," "Air Handler," or "Condenser." Reset it once.
  • Outdoor unit reset: The outdoor unit may have a small red reset button on the side. Press it once if the unit isn't running.

Step 2: Call for Service Early

During a heat wave, HVAC companies book up fast. Call New Lenox Heating at 815-893-3642 as early in the day as possible. Same-day appointments go quickly in July and August. The earlier you call, the better your chances of getting service that day.

Step 3: Stay Cool While You Wait

  • Close all blinds and curtains, especially on south and west-facing windows
  • Use ceiling fans and box fans to improve comfort through evaporation
  • Avoid using the oven or dryer, which generate significant heat
  • Move to the lowest level of the house — basements stay significantly cooler
  • If you have elderly family members or young children, consider going to a public air-conditioned space while waiting
