Who It's For

New parents in the Birmingham metro facing an HVAC failure they don't have time to research.

What's Inside

The first-30-minutes priority list, infant safe-temperature science, alternative cooling that's actually safe, when it qualifies as a 911 health emergency, and the call script.

Why It Matters

Most HVAC problems in Birmingham are preventable or fixable cheaply if you know what to look for. This guide tells you what.

When the AC dies with an infant in the house, the rules change. You don't have hours to troubleshoot. This playbook is the priority order — what to do in the first 5 minutes, the first 30 minutes, the first 2 hours. Written specifically for Birmingham summer conditions. Direct. No fluff. Calm.

Minute 5-15 — passive cooling

Do all of these before calling anyone:

  • Close every blind and curtain — sun load (or stored heat in walls) is the enemy
  • Turn off every interior light
  • Turn off the oven, stovetop, dryer, dishwasher
  • Run every ceiling fan — direction should blow downward (counterclockwise in summer)
