Should I Get A Whole House Humidifier?

Hello,

I have two forced air units (attic and basement) so I would actually need 2 in-duct units, correct? My place is approx 1800 sqft over two levels of living space. Which brands / types are generally recommended? I do not have floor drains, but the HVAC units each have pumps/hoses that feed into the plumbing system for both heating and cooling seasons. Thanks!

I would think the one in the attic would cause freezing issues. The one for the basement would be your best bet. What is the humidity in the house?

I feel a humidifier is not needed and causes more problems then good. Mold in the ducts, bacteria growth ect......
A tell homeowners use a tabletop unit.

But they do have these new steam units that I here good things about.

Here is an example. There are many brands out there.

Whole-House Steam

The comfort zone for hunidity is 30-60 percent. You might be at this level and may be wasteing money.

Whole house humidifiers are worth every penny IMO. Again, basement is best bet due to freezing issues in attic. I DO NOT recommend steam humidifiers, they break down constantly and have many problems! A flow-thru humidifier would be best IMO.

Hmm, so if my main problem with humidity is in the upper floor (serviced by the attic HVAC unit) then I should opt out of a whole house humidifier due to freezing issues? The upstairs is 1000 sqft so I was hoping to avoid 3 tabletops going. I appreciate the input. Thanks

adding humidity to basement will help whole house but you are correct it wont do the whole house with 2 systems, but will definitely help!

Wow, two furnace for a 1,800 sq ft home??

How old is your home? Tighten the house will help keep the humidity in the home.

I'd put the bypass humidifier on the furnace in the basement, and the humidity will work it's way to the dryer area of the home.. Also, heat rise too, so the humidity will go up with it.

Why you only have 1800 sq ft. These are good for 2900 sq ft.

MoistAIR Whole House Humidifier HD1407

2500 sq ft

Essick Air H12-001 Humidifier Whole House 12-Gallon

Put it in a central location buy the stairs.

@ Jay1 Yes - 2 units for a small home. I guess to have two zones? It is only 2 years old, but it can get very dry (15-30% r/h on the upper floor).

@ lawrosa - Would you recommend those models over an in-duct system?

Just do a search of humidifiers on this site and see all the trouble issues with induct systems. I have seen mold and mildew issues all the time. Its what your breathing. Why add moisture to your duct work so bacteria could grow. This is why duct cleaning has become so popular.

What is the humidity in your house? Have you checked it? Do you even need one? I think people think they need them because thier neighbor has one and you go on a service call and see the windows streaming with condensation.

Ahh... Just my 2 cents. The HVAC guys will be commenting Im sure.

House is 2 years old in New England. Winter humidity generally runs below 35% without a humidifier. I think I have heard enough to be anti-in duct humidifier and will go with another option. Thanks!

A two years old house should be pretty tight that you don't need one.. Maybe you got leaky ducts in the attic.
