whole house humidifier

Anyone had any experience with getting a central humidifier from Reliance? I know they use a flow through humidifier but don't know the model.
If not Reliance, has anyone had a good experience with a company that they used? (in the Oakville area).

Don't buy a humidifier from Reliance, or rent any appliances (furnace, AC, water heater, etc) for that matter. It's all a rip off for you. You end up paying many times over for it. Buy a humidifier from a reno store for $100 and have a handyman install it if you can't do it your self.

Install one yourself. Don't get Reliance or any of those "rental appliances" to do it.

I'm a TOTAL n00b, and I installed a whole house flow-through Honeywell Humidifier myself. Cost about $150 from Princess Auto. Pads are $13. I'm surprised it was that easy. Well they also have youtube videos. Aprilaire is also a good brand I hear.

I've got a desert springs rotary humidifier, works great with my ecobee 3 and doesn't need pads.

I recently went to have a humidifier installed and an HVAC guy I know and trust talked me out of it. He says they almost always cause rust and corrosion in the duct work as well as shorten the life of the furnace. Plus he said people have a habit of not adjusting them and/or not understanding how temperature differences affects the humidity level, so when the temperature drops quickly, suddenly the humidity level in the house skyrockets and mold forms.

I agree that most people wouldn't set their humidifier up properly. I installed and setup mine properly and we're very happy with a comfy humidity level year round.

I have the same one. How do you drain the excess water?

Perhaps I'm going to be schooled here but isn't that what a humidistat is for. You set it at the desired humidity and the humidifier then turns on and off based on the humidity of the home.

you're right there is but most do not adjust to outside air temperatures. they just set it and forget it like their chicken.

Agree. It is hard to set the central humidifier to the right humidity for the entire house. I installed it but gave up using it for years Face With Tears Of Joy

Can't say I've ever had an issue. If adjusting the h-stat is too much trouble, just get a smart one to do it for you.

I currently have 2 humidifiers I purchased over the weekend and I'm planning to return the other one that supposedly covers 2600sqft (more like 850) because I want an entire home humidifier.

... But rust and corrosion you said? I'm worried. The original owners of my home have an old Wait 6000 but when I took possession of the home they had it unplugged and it looks like it hasn't been used for a while.

all I’ve been doing is open air flow and set the humidistat to the percentage I want when I switch over to heater mode. In the spring I disable the air flow and dial off the humidistat , turn off heat mode and change the humidifer filter.

Is there anything else I should be doing differently to prevent mold and rust?

Nope. As long as you don't have stale water sitting around you should be fine. Just check it occasionally and clean filter/basin as necessary (usually in the spring).
