Summers in Davis, CA can be brutal. Triple-digit temps and dry conditions are the norm—and your air conditioner works overtime. But if you’re relying solely on your HVAC system to keep cool, you’re likely overspending and underperforming.
Good news: You can fight the heat without cranking the AC—by upgrading the materials that surround your home.
This guide shares smart, energy-efficient exterior upgrades—like windows, siding, and shading structures—that make your Davis home cooler, more comfortable, and more affordable to run.
- Start with Energy-Efficient Windows
Windows are one of the biggest culprits of heat gain in summer. Older windows can turn your home into a greenhouse.
🔍 How modern windows keep your home cooler:
- Low-E coatings reflect infrared and UV rays
- Double or triple-pane glass insulates against heat
- Argon gas fills reduce thermal transfer
- Tight seals and quality frames block drafts and leaks
🏡 In Davis, replacing old aluminum or single-pane windows with Milgard®, Simonton®, or Marvin® energy-efficient options can cut cooling costs by 25–30%.
- Upgrade to Reflective, Insulated Siding
The sun doesn’t just hit your windows—it bakes your walls, too.
🌞 Best siding for heat control:
- James Hardie® fiber cement siding: Fire-resistant, doesn’t warp, and can be paired with rigid foam insulation
- LP® SmartSide® engineered wood: Lightweight and available with radiant barrier backing
- Light-colored siding: Reflects sunlight better than dark tones
🎯 Bonus: Upgrading your siding also allows you to add house wrap or exterior insulation, creating a thermal break that keeps cool air in and hot air out.
- Block Heat with Smart Shade Solutions
Sometimes, staying cool is all about where the sun hits—and when.
☀️ Smart shading strategies for Davis homes:
- Awnings over south- and west-facing windows
- Pergolas or patio covers for outdoor relief
- Shade sails for flexible, modern coverage
- Window film or interior shades as budget-friendly additions
🌿 Consider adding deciduous trees or tall shrubs to provide natural shade without blocking winter sunlight.
- Seal the Envelope: Caulking, Flashing, and Venting
Hot air will find a way in—unless you seal the gaps.
🔨 Key upgrades to keep heat out:
- Re-caulk around all windows and doors
- Add flashing tape during window or siding installs
- Use insulated attic vents and radiant barriers in the roofline
- Seal crawlspaces and attics to eliminate heat pathways
💡 Many Davis homes were built before energy efficiency was top of mind. A full exterior checkup can reveal hidden leaks and heat sinks.
- Bonus: Cool Roof Upgrades
If you’re planning a roofing update, opt for a cool roof that reflects sunlight and releases heat better than standard materials.
🏠 Cool roof features:
- Light colors or reflective coatings
- ENERGY STAR® rated shingles or metal panels
- Radiant barrier underlayment
Combined with efficient windows and siding, your home becomes a true heat-defying fortress.
