Why Arizona's Climate Makes Ductwork Efficiency Matter
Arizona has a hot desert climate with about 169 days above 90°F per year, summer highs around 106°F, and low average humidity of 37%. In dry, extreme heat, ducts routed through attics can reach temperatures well above ambient — causing conditioned air to absorb heat before it ever reaches living spaces. Proper insulation on attic duct runs and tight sealing at all joints are the two biggest factors in keeping cooling costs under control in Arizona's summers.
