    Our original humidistat was 19 years old and looked dated. I ordered its replacement and received it in three days. It was a snap to install and looks great. I would recommend Aprilaire to my friends.

    Product is just ok. (less old fashioned than the 12 year old original) Aprilaire could benefit from a professional product designer (think iPad ). Your handling and shipping charge was outrageous. Do not contact me. Don Sullivan

    I replaced the Humidistat but am still having problems with sufficient humidity reaching various parts of the house. Is there an issue with this system and a High Efficiency furnace and how the system should work?

    Original humidstat failed after after a year - apparently a USED one had been installed instead of a new one. HVAC company now out of business - now I know why. Called around, no one would sell me a replacement OTC and I'd have to pay for a service call anyway - more than the humidstat costs from estore. Replacement arrived in timely manner, easy to install of course. So far, OK.
