Climate-controlled storage units run 15-20F above the advertised range because facilities skip HVAC zoning

Facilities advertise 'climate-controlled' units at 55-80F, but many only climate-control the hallways while individual units on exterior walls or upper floors regularly hit 95-100F in summer because the HVAC system is not zoned to each unit. Customers storing wine, electronics, photographs, or wooden furniture discover warping, mold, or corrosion months later with no recourse because the lease says 'climate-controlled' without guaranteeing a specific temperature range inside the unit. This persists because no state defines what 'climate-controlled' legally means for self-storage, facilities save $50,000-$100,000 per building by using a single central system instead of per-unit HVAC, and customers cannot monitor conditions inside their unit because facilities prohibit installing personal temperature loggers.
