Although it’s the first instinct of many to call an HVAC specialist when encountering a moldy smell, new buildings don’t often have issues with HVAC systems. Instead, the smell is more often due to moisture in construction and building materials. Most HVAC systems are not intended to dry out construction materials, and without the proper equipment mold can grow in as little as 48 hours.
Moisture can come from rain or snow before the building is enclosed, leaking pipes, wet concrete, or condensation. If not dried completely as soon as possible, you run a real risk of mold infestation. The construction drying tool of choice for most experienced professionals is the desiccant dehumidifier.
Desiccant dehumidifiers are able to dry the air to very low dew points, without being inhibited by cold weather. This makes them perfect for construction sites. They’re also great for drying concrete, which can be difficult in spaces that aren’t completely enclosed.
