Low humidity in houses is connected to a number of health concerns including respiratory ailments and increased risk of contracting illnesses. Moreover, dry indoor air has been known to crack and warp wood furniture and floors and cause wallpaper to peel away from the wall. These problems are especially noticeable during cold weather when the heating system is working overtime to keep the house warm.

To raise humidity levels, many consumers are installing a whole house humidifier as part of a home improvement project. These units are installed adjacent to the furnace, and typically feature a humidistat that makes it possible to control the humidity level for every room. Sometimes called console humidifiers, these units add water to heated air and then distribute it throughout the house.

The least expensive type of console humidifier features a belt to propel humidified air to every room. Known as a drum system, the unit can be purchased for about $80 to $275. A more advanced system utilizes an evaporator pad. Air heated by the furnace passes through the evaporator pad, collecting water on the way before being sent into the house. These are slightly more expensive, costing between $100 and $300. Consumers looking for a high level of sophistication and better humidity control sometimes choose a steam humidifier. These units are capable of operating without being integrated into the heating and cooling system, but they are more expensive. The least expensive of these models costs at least $300 and may cost as much as $1,500.

Humidifiers are often added to a heating system in conjunction with a larger renovation project, so most consumers find it easiest to hire a contractor to install the unit. However, because installation requires knowledge of plumbing and wiring in addition to working with sheet metal, professional installation is sometimes preferred even when installation is a stand-alone project. The cost of labor and additional materials can add significantly to the cost. On average, labor and parts cost between $100 and $300, though that price will rise with more sophisticated steam humidifiers. Labor on installation of a steam humidifier can be $500 or more.

Most consumers spend between $475 and $700 on humidifier installation. The result is a healthier, more comfortable home in which the inhabitants are subjected to fewer illnesses. Moreover, a humidifier helps to protect the floors, furniture and walls, making humidifier installation a worthwhile expense.
