My house is 107 years old. I'm wanting to add a whole house humidifier . Is there any problems with that? You know old houses aren't air tight.

Before installing a humidifier. You might want to seal up the house better first. This will pay back quickly in savings on both heating and cooling cost. Along with decreasing the amount of moisture that has to be added to your home in the winter.

The Aprilaire 600A is a good choice for a humidifier. But depending on the size of your house, and how leaky it is. May not be large enough.

My is probably a little over 2000 sq ft. Working on insulating right now. House has no insulation in walls. Attic has some now since I put it up there a few years ago. Doing a kitchen remodel so tore down plaster on exterior walls to insulate. The rest of the house im going to cut holes in the walls and use blow in.

Not much choice. That is where the furnace is located. I'm in Texas so freezing is pretty rare. I'm installing a condenaste pan under the unit and it will have a float to turn off system in case of overflow. I may add an alarm.


I've tried running humidifiers in the house but they can't keep it comfortable. We only run the heat for 2-3 months and 25 is a very low temp. I'm going to use hot water so that should also eliminate the any freezing issues. I'm just tired of feeling cold at 72F.

I installed a 95% furnace last year which has a condensate drain to outside. I'm a bit concerned about it freezing also. I'm moving that to an interior drain with the humidifier.

Heating the attic was a joke, and isn't 25*F below freezing, hows that work with all that condensate that comes off a 90% furnace, and water for the humidifier.

I think that doing what you are doing (90% and humidifier) is like playing Russian roulette, one day it will cost you big.
