    :mad: We had our heat pump replaced and all the ductwork replaced. Before they completed I expressed concern about moisture. There had never been a problem before. After 5 visits we still have condensation on a bedroom duct grill and a bathroom duct grill which is ruining our ceiling. My question is what could be the problem? Flexible ductwork replaced rigid ductwork and a high effieciency unit with an environmental control thermostat. We have heard don't touch the thermostat, it is incorrectly pressurized, and the heat difference from the skylight is causing a problem. So now what??

    Without the benefit of seeing the problem firsthand, it sounds like the duct insulation is insufficient, the ceiling insulation has been displaced, the supply airflow is too low, or a combination of all. Cold surfaces attract moisture; if the surface temperature is lower than the dewpoint of the surrounding air, condensation will occur.

There was a question I neglected to ask in my previous note. How do I fix a situation involving a radiator. Whenever the boiler turns on and it begins to heat the system, there is a radiator that makes a loud noise as if someone is banging it with a metal object. How do I fix that? Thanks again for...

I have a Goodman furnace. The thermostat is telling the furnace to come on, but it does not. This happens at least twice a day. I have to turn it on by turning the furnace on and off. There is a blinking red light that flashes five times, which I do not know what that means. Please Help
