Well, after months of the Humidifier not working, it has finally been fixed. Originally it was thought to be a problem with the humidistat. I then called in an HVAC professional, since my installer kept blowing me off. After that visit it was determined that the problem was with the WaterFurnace thermostat. The humidifier worked when given 24 volts AC. The problem was in the thermostat in which 24vAC was not being sent. This was also verified by switching the fan setting from automatic to manual. What was expected was 24vAC would be detected on the fan call (Common and green wires). There was no voltage being sent.

Also noticed during the winter that the air handler fan was not working in second stage. It was noticeable when the fan kicked into high operation. I did not notice that this winter.

After the Tech from Optimal Energy ( Optimal Energy LLC ) replaced the thermostat with a newer WaterFurnace thermostat, all operated as it should. I had him check the rest of the system for proper performance. What was found was that my ground loop pressure was low as well. Now with these problems resolved, my HVAC system should be good to go.

I noticed back in early January that my Humidifer was not operating. Previous issues were that the humidifer was cycling very quickly on and off at times. I called my geothermal installer with the problem and was asked to do more troubleshooting. The humidifier finally quit and does not work now.

I called my Geothermal Installer. Not surprised that I needed to do some troubleshooting before anyone would be sent out to resolve the issue. I found that when installed, the 24 volt power was coming from the Bryant Air Handler not from a seperate transformer for the humidifier. I learned that the 24 volts was not present at the Air Handlers circuit board.

I relayed this information to my installer and due to other commitments, I was told to “sit tight", they’ll get back to me. Well, it is now near the end of February and no word from my installer. I have left numerous voice mails. I get the feeling that he doesn’t want to return my calls.

Needless to say that the humidifer is still not working. It is a really uncomfortable situation. Had I known the type of response I would get from my Geothermal Installer, I never would have had them install my HVAC system.
