Ventilation, Humidity and Health

Commented on by David C.
I have 2 furnaces in my house. Each supply around 1300 sq. ft. Do I need to have a humidifier put on each furnace, or would it be possible to get a really big unit put in downstairs only?


We would a little more information, such as the age of the home and it’s tightness but on average a model 600 humidifier will cover 1000 sq ft in a loose home, 2000 sq ft in an average home and 4000 sq ft in a tight home.  If you do decide to go with one humidifier, please have your installing contractor install the humidifier on the furnace that functions most of the time.
