What Humidity Control Systems Do

Think of a humidity control system as a thermostat for moisture. Too dry? It adds some. Too damp? It pulls it out. Most people have never heard of one, but the target is simple: keep the air in your house between 30 and 50 percent relative humidity. That is where you feel comfortable, your HVAC works the way it was designed to, and mold has nothing to feed on.

People think Las Vegas equals dry air, full stop. For about nine months of the year, that is true. Your skin cracks, your wood floors shrink, and your sinuses let you know about it. Then monsoon season rolls in from July through September and reverses all of it. Outdoor humidity jumps into the 40s and 50s. Your AC pulls some of that moisture out while it cools, but it was never built to be a dehumidifier. When it falls behind, you end up with damp ducts, wet coils, and air that feels sticky even though the thermostat says 73.

Here is what a humidity control setup from Pure typically includes:
  • Whole-home humidifier. Ties into your ductwork and your water line. When the air gets too dry, it feeds moisture into the airstream as the blower runs. There are a few types. Bypass units ride the existing airflow. Fan-powered units push harder for bigger homes. Steam units make their own moisture and work even when the HVAC is off.
  • Whole-home dehumidifier. Does the opposite. During monsoon months, it strips moisture out of the air before it circulates through your house. Forget the portable unit sitting in the corner of a bedroom. A whole-home dehumidifier hooks into the ducts and handles every room at once.
  • Humidity sensing and controls. A humidistat keeps track of moisture levels and kicks the equipment on when things drift out of range. If you have a smart thermostat, the controls can tie in and adjust on their own based on what is happening inside and outside.
  • Condensate drainage. A dehumidifier pulls water out of the air, and that water has to go somewhere. We run a drain line to a floor drain or exterior outlet so you never have to empty a bucket or worry about overflow.

Not every home needs both a humidifier and a dehumidifier. Some only need one or the other. We figure out which based on a humidity reading, a look at your HVAC setup, and a conversation about what you are actually experiencing.
