John Nicholas replied to Pat Dundon's discussion Basements and BAS"Most homes in this area have full conditioned basements. They are finished and used for all types of living activity.

John Nicholas replied to Home Energy Magazine's discussion UV light in Furnace?"Indoor air quality starts with a lot of things! The last item you do is filter. Why allow everything into your home and then try to find it and remove it.

John Nicholas replied to Jack Baikoff's discussion Measuring fresh air intake ducted to a return and no way of measuring from outside."Ted,
That is a sealed combustion furnace. We don't know what the hot water heater is.
If that is someones idea of mechanical ventilation to meet ES 3.0, I believe they missed a class somewhere. Code compliance for fresh air in this area…"
John Nicholas replied to Jack Baikoff's discussion Measuring fresh air intake ducted to a return and no way of measuring from outside."Set up your blower door and duct pressure testing. Get a duct leakage to the outside, with the vent open. Then repeat with the vent taped off. That would be the amount of air flow in CFM at 25pa through the duct. If you are wanting the…"
