Whole-House Humidifiers in Whitehall, MT

Cold outdoor air holds very little moisture. Bring it inside, heat it to seventy degrees, and the relative humidity collapses — often into the teens, which is drier than most deserts. Every hour your furnace runs, that dry air is being circulated through the house.

The effects are cumulative: wood shrinks and joints open, static builds on every surface, and your sinuses dry out overnight. Air at proper humidity also feels warmer, so many homeowners find they are comfortable a degree or two lower on the thermostat once humidity is corrected.

Bypass and fan-powered evaporative units mount to the supply or return plenum, use a wetted pad and your furnace's airflow, and are the practical choice for most homes here. Steam humidifiers produce more moisture independent of furnace operation and suit large, leaky or very dry homes, at higher installation and operating cost.

We size from your home's volume and tightness rather than installing whatever fits, because an undersized unit never reaches setpoint and an oversized one invites condensation problems.

Too much humidity in a cold climate is its own problem: water forming on window glass and, worse, moisture accumulating inside wall assemblies. The answer is outdoor-reset control — as it gets colder outside, the target indoor humidity comes down automatically.

We set that curve for our design temperatures and show you how to read it, so you get comfort in the thirty-to-forty percent range during moderate weather without frost on the windows at twenty below.
