Question about Aprilaire 700 Humidifier
I just had an Aprilaire 700 installed on my 90k hi eff furnace (new last year). I keep hearing a hi pitched whistle when the humidifier goes on. Trying to get the HVAC guy back - but he's busy installing and fixing furnaces - very cold this week.
You may be having problem with air scaping from the base of the hum. it will probably may have to put silicone around the base of the hum. to stop the air scaping.
