How Arizona conditions shape HVAC planning
Arizona planning must account for extreme dry heat, intense solar gain, monsoon dust and evaporative cooling. Sensible cooling load, solar gain, duct leakage through hot spaces, filtration and evaporative-cooler suitability are central in dry climates.
Climate describes likely loads; it does not size equipment. Ask for property-specific load calculations, duct or distribution findings, design temperatures and documented startup measurements when they apply.

Review the peer-reviewed NOAA Arizona State Climate Summary for observed climate trends and state-specific extreme-weather context. Degree-day and design-temperature decisions should use the serving location and current code documents, not a statewide average.
