To prevent mold, set your AC to keep indoor humidity between 30-60% and the temperature generally between 68°F to 78°F (20°C to 26°C), leaning towards the warmer end (74-78°F) in humid summer months to help dehumidify effectively without making surfaces too cold for condensation. Cooler settings (below 72°F) can overwork the AC and increase humidity, while warmer temps (above 78°F) can encourage mold if humidity isn't controlled. 

Does cold air help prevent mold?

No, cold temperatures don't prevent mold; they just slow it down or make spores dormant, but mold will reactivate and grow rapidly once temperatures rise and moisture is present, often thriving in cold, damp winter conditions due to condensation.
