Definition
A unit added to your HVAC system that adds moisture to dry winter air, improving comfort and protecting woodwork — a common upgrade in the upper Midwest.
Why this matters for your home
A whole-home humidifier installs directly on your HVAC system and adds moisture to the air as it circulates, holding your home at a comfortable relative humidity through the dry heating season. Unlike portable units, it treats every room and refills automatically from your plumbing.
Minnesota winters can drop indoor humidity into the teens, which dries out skin and sinuses, worsens static shock, and cracks hardwood floors, trim, and instruments. Balanced humidity also lets you feel comfortable at a slightly lower thermostat setting, which trims heating costs.
