HVAC question

[Scott K]

On my a/c /furnace ducts directly on top of the furnace, I have a central humidifier attatched to it. Now I have used it one winter in the 6 years I lived here. I was down looking at my furnace and noticed all the air leaks in the duct work, so I grabbed a role of duct tape and started taping. I was looking at the water coil (heater core looking thing) for the humidifier and seen the there is a 1'x1' hole cut in the duct work for this, the now cool air blows up through it then blows into the return duct. So basicly the fan is blowing the cold air directly into the return duct through the humidifier.

My question, isnt this just a waste of air, and if I removed it and blocked off the hole, that would force more cold air out of the vents in the house? Or am I over analyzing it, and its not effecting anything?

Most of the dudes I know with humidifiers in their central system have removed them.

They also have a reptuation for destroying heat exchangers in furnaces.

there should be some sort of dampner you can turn to shut off the hole you are talking about for the summer months

There was a dial I could turn to adjust airflow from low to high. I removed the unit and blocked off the hole, as I said earlier I have only used it once!

Thanks for the info!
