Arizona summers are no joke. With temperatures regularly soaring above 100°F, keeping a home cool without skyrocketing energy bills can feel like an uphill battle. The good news? Smart construction choices and strategic upgrades can make a dramatic difference in comfort, efficiency, and long-term savings.
Here’s how to build—or retrofit—a home that stands up to the desert heat.

1. Start with Smart Orientation and Design - The way a home is positioned on a lot can significantly impact indoor temperatures. In Arizona, minimizing direct արև sunlight exposure is key. Homes designed with longer east-west walls reduce the amount of harsh afternoon sun hitting living spaces. Incorporate covered patios, overhangs, and shaded entryways to naturally cool exterior walls and windows.

2. Invest in High-Performance Insulation - Insulation isn’t just for cold climates. In hot regions, it acts as a barrier that keeps heat out. Attics, walls, and even floors should be properly insulated to prevent heat transfer.

• Use high R-value insulation suited for desert climates
• Consider radiant barriers in attics to reflect heat away
• Seal gaps and cracks to prevent hot air infiltration

3. Choose Reflective Roofing Materials - Your roof takes the brunt of the sun’s intensity. Traditional dark roofing absorbs heat, raising indoor temperatures and increasing cooling demands.
Opt for:

• Light-colored or reflective shingles
• Tile or metal roofing with high solar reflectance
• “Cool roof” coatings that deflect sunlight

These materials can lower roof surface temperatures by up to 50°F.

4. Upgrade to Energy-Efficient Windows - Windows are one of the biggest sources of heat gain in a home. Poor-quality windows allow heat to pour in, especially during peak sunlight hours.
Look for:

• Double or triple-pane glass
• Low-E (low emissivity) coatings
• Gas-filled windows for better insulation

Adding exterior shades, solar screens, or tinting can further reduce heat gain.

5. Seal and Tighten the Building Envelope - An airtight home keeps cool air in and hot air out. Even small leaks around doors, windows, ducts, and electrical outlets can significantly impact energy efficiency.
Focus on:

• Weatherstripping doors and windows
• Sealing ductwork
• Using spray foam in vulnerable areas

6. Optimize HVAC Systems - A well-designed HVAC system is essential in Arizona. Oversized or outdated units waste energy and fail to maintain consistent comfort.

• Install high-efficiency air conditioning units (SEER-rated systems)
• Use programmable or smart thermostats
• Consider zoning systems for better control

Routine maintenance—like cleaning filters and checking refrigerant levels—also keeps systems running efficiently.

7. Incorporate Passive Cooling Strategies - Passive cooling reduces reliance on mechanical systems by using natural airflow and shading.

• Install operable windows for cross-ventilation
• Use thermal mass materials (like concrete or adobe) to absorb heat during the day and release it at night
• Add shade trees or desert-friendly landscaping around the home

8. Solar Power: Turn Heat into Energy - Arizona’s abundant sunshine makes solar panels a natural fit. While they don’t directly cool your home, they offset the energy needed to do so.
Benefits include:

• Lower electricity bills
• Reduced dependence on the grid
• Increased home value

9. Efficient Lighting and Appliances - Everything inside your home contributes to heat—including lighting and appliances.

• Switch to LED lighting (produces less heat than incandescent bulbs)
• Choose ENERGY STAR-rated appliances
• Limit use of heat-generating devices during peak daytime hours

Removing a wall in your home can open it up and increase the home’s value, but are all walls the same? Absolutely not! Removing a wrong wall can cause the whole house to collapse during the remodeling job. This is why you need to determine if the wall in question is load-bearing.

What is a load-bearing wall? Load-bearing, or bearing walls, support the floor’s weight or roof structure above them. They were designed to transfer the weight from the roof through the floors and down to the foundation. They allow the weight to be distributed equally along the structure. A nonload-bearing wall, or partition wall, can be completely removed and the structure will remain intact, though some may still have support beams installed.

There are ways to determine if the wall you want to remove is load-bearing. 

• If you have access to the blueprints, they will show you which walls are load-bearing.
  
• Exterior walls are usually load-bearing. Newer homes tend to use the front and back exterior walls as load-bearing, while more older homes use all the exterior walls as load-bearing.
  
• Usually walls that run perpendicular to the joists are load-bearing.
  
• Walls that are parallel to the joists are rarely load-bearing, but there are some instances where a bearing wall will be aligned directly under a single joist.
  
• If purlin bracing is attached to the top of the wall or supported by the wall, it is load-bearing.
  
• If the wall has a beam, column or other wall directly below or following the same path, it will be load-bearing.
  
• More than 6 inches thick, the wall will be load-bearing.
  
• Walls that are in the center of the building will tend to support most of the roof’s weight.
  
• Walls that end in supports or columns are most likely load-bearing.
  

Removing a load-bearing wall is more costly and complicated than removing a partition wall. A single-story structure can start at $3K. If the wall has plumbing or electrical, that will all need to be rerouted, which will increase the price more. Second-story load-bearing walls can start at $10K and up. Once the wall has been removed, the new beam drywall and finish must be installed.

If you are uncertain, please reach out to us and we can come out and inspect the wall, determine if it’s load-bearing, and how to safely remove it without causing the structure to fall down!
