15 Tips To Help Cool Your House This Summer + Lower Energy Cost

What happens here

Ensure your attic has adequate insulation based on your climate zone. Proper attic insulation prevents heat transfer from the hot attic into your living spaces in summer (and heat loss in winter), making your home significantly more energy-efficient. In warmer, southern climates, an R-value of R-38 is often recommended, corresponding to an insulation depth of 13-14 inches. For colder, northern climates, an R-value of R-49 is typically needed, requiring 16-18 inches of insulation. You can add insulation by purchasing bags from a home improvement store (e.g., Home Depot, Lowe's) and renting their blowing machine for easy application.

Goal: Improve thermal efficiency by ensuring adequate attic insulation

Tools and materials

  • Insulation Blowing Machine — Spreading loose-fill insulation in the attic
  • Tape Measure — Measuring current insulation depth
  • Loose-Fill Insulation — Increasing attic insulation to the recommended R-value
