    Something new every day....

    Got a call from a tech that I know and trust. He tells me that he has a start capacitor that is "leaking" a white powdery subsatnce. He claims this is because the start cap is mounted on its side.

  3. Calcium like deposits at pressure tap of IDM housing

    I have been receiving several (40+/-) reports of a white, flakey deposit that forms and blocks the hose connection at the IDM blower housing.

    Balance point

    I would think one should avoid the defrost cycle because it is a large energy user.

    I would suggest the Honeywell TH8220 as the minimum. The YTH9000 series IS the premium with humidity control and many other options plus a damper kit for outdoor air.

    Right up front- I am prejudiced. Modulating a furnace is a comfort issue. I challenge anyone to be able to discern the difference in comfort level between 1% and 5% modulation.

    Why do some manufacturers use HSI while others use DSI?

    I should think the DSI would be less troublesome than HSI.

    You might want to see if the air handlers or matched to the heat pumps. You didn't indicate the heat pumps were changed.

    I'm confused with your post. If your logs are in a fireplace one would think the combustion products would go up the chimney.

    Do you have the flue damper closed?
