Storing in San Marcos: what to know

Long, hot and humid summers make climate control the most-requested feature in Texas. In an unconditioned metal building, summer heat can soften vinyl, warp records and wood, and humidity invites mold and mildew on fabric, mattresses and paper.

Local tip: Ask whether climate-controlled units also control humidity. In humid states that matters as much as temperature.
