Can Your Exterior Paint Color Keep Your Arizona Home Cooler?

In the Arizona sun, the color you paint your house doesn't just change how it looks. It changes how much heat the walls soak up. Here's what that means for your home and your AC bill.

Lighter colors reflect more heat

Light, warm neutrals like sand, tan, and soft greige reflect more sunlight than dark colors, so the walls and the air just inside them stay cooler. Deep browns, charcoals, and dark blues look great but absorb more heat, especially on south- and west-facing walls that get blasted all afternoon.

Look for the LRV

Every paint color has a Light Reflectance Value (LRV) from 0 (black) to 100 (white). For Arizona exteriors, a higher-LRV body color helps with heat. You can still use darker tones for trim, accents, and the front door, where the square footage is small.

Cool-wall paint goes further

Heat-reflective "cool wall" paint technologies reflect more infrared energy than standard paint of the same shade. On a hot Phoenix elevation, that can make a real difference in how the wall feels and how hard your AC works.
