Artwork, old photos and paper documents may not be the first thing to come to mind when thinking about HVAC storage, but they require precise conditions in order to maximize longevity. Excessive heat can speed the deterioration process, while temperature fluctuations may flake the ink and wrinkle the paper. Artwork can crack and lose surface materials in unstable humidity conditions.
General artwork storage conditions include
Temperatures around 65°F (18°C)
Relative humidity around 60%
General document conditions include
Temperatures below 70°F
