Attic Heat Trap: Why Your AC Can’t Keep Up

Attic Heat Trap: Why Your AC Can’t Keep Up

The Hidden Heat Trap That’s Overworking Your AC

During summer, attics in places like Arizona can soar above 130°F. Without proper ventilation, that heat radiates downward—into your living space and garage. The result? Your AC struggles to cool, longer run cycles, and your energy bills climb.

Most homeowners blame their air conditioner, but the attic is often a silent culprit.

How an Overheated Attic Impacts Your AC

When attic heat is trapped:

  • 🔥 AC Overload: It runs nonstop, wasting energy.

  • 🛑 Uneven Cooling: Top-floor rooms stay warmer.

  • Shorter AC Lifespan: The system wears out faster.

  • 🧱 Hot Garage, Hot House: Garage heat migrates into the home, compounding the problem.

Your cooling system is fighting two battles: the outside heat and the heat inside your attic. Insulation helps—but it’s not enough. It only slows heat transfer. It doesn’t release the trapped heat.

Without active attic ventilation, your attic becomes a sealed oven. That’s where Cool My Garage comes in.
