JulieFoothill regions across California experience dramatic temperature swings.
Hot daytime sun.
Rapid nighttime cooling.
This creates a large delta T, the temperature difference between inside and outside.
The larger the delta T, the faster heat tries to escape.
Homes near mountain or canyon areas face:
- Stronger pressure differences
- Faster stack effect cycling
- Greater attic heat loss
Without strong attic insulation and proper air sealing, heat drains rapidly after sunset.
That is why heaters run long cycles but rooms never feel comfortable.
