Thank you for visiting Humidifiers.net! We are your premier source for humidifier parts, sales, service/repair and installation in Northern Virginia, including the newest generation of automatic humidifiers that actually think for themselves! As the moisture in your indoor air evaporates, the temperature in your home feels colder. In the winter, that means you will likely turn up the theromstat to feel warmer. Your heating system will use extra energy warming up the dry air. By putting moisture back into the air, a humidifier allows you to remain comfortable at a lower thermostat setting, which lowers your energy costs.
