  • HOW CAN I RAISE THE NEUTRAL PLANE?

    If there are larger holes in the top of the house than in the bottom of the house, the neutral plane will be raised.I guarantee that if the roof of your house were removed (still blocking the snow with a giant umbrella) there would be no condensation problems in the walls. (This solution is no...
  • HOW DO I GET MY PLANNED-HOLE-HIGH-IN-THE-HOUSE?

    The best household ventilation system is a constant operation fan powered balanced air-change system -- a central system that sucks stale air out an exhaust duct and blows an almost equal amount of fresh air into the house through an intake duct. These systems will usually require a heater o...
  • WHAT IS A CONTROLLED COLD-AIR INLET?

    Stale, humid air must be exhausted from the house, both to allow for fresh air and to maintain a high neutral plane. For this reason we need a planned-hole-high-in-the-house, but the air going out must come into the house from somewhere. If you carefully seal all the leaks in the house to m...
  • DO I NEED AN EXHAUST FAN IN THE BATHROOM?

    Yes. If your house is well sealed the bathroom will create too much humidity, and an exhaust fan will get rid of the tremendous moisture produced by a shower quickly, before it spreads through the house. This excess load function of the exhaust fan will work even if the bathroom exhaust ducting...
  • DO I NEED AN EXHAUST FAN IN THE KITCHEN?

    An exhaust fan in the kitchen is not an absolute necessity. However, it serves two functions: it cuts down on humidity and it removes grease, smoke and odours. If none of these bother you -- and that has a great deal to do with how you like to cook -- then you can get along without one.If ...

  • ARE WHOLE-HOUSE EXHAUST FANS WORTHWHILE IN A COLD CLIMATE?

    There is no simple answer to this one. Let's narrow the field and talk only about exhaust fans that do not use things like the air-to-air heat exchangers for heat recuperation.Government literature from the Prairie provinces do not recommend them if they must be installed in the attic (the st...
  • ARE BALANCED AIRCHANGE SYSTEMS WORTHWHILE?

    A balanced air-change system is a fan operated system that forces out stale air through exhaust ducts and forces in an equal amount of fresh air through controlled intake ducts. The difference between this and a central exhaust system is that the input air is under active control and balance...
  • Proper installation of new whole house ventilation systems

    Joan from Armstrong, BC is having trouble adjusting the ventilation system in her new home to keep condensation off the windows. She told us the kind of system she has and said that it was required by the building code. Actually no specific system is required by any of the building codes. ...
  • How do you clean an exhaust duct?

    If it is a plastic flexible duct, it can be very difficult to clean precisely because it is so flexible. But all ducts can be cleaned with "duct brushes". These are round brushes similar to chimney sweep brushes but much softer, with either a string pull or a rod on the handle. If you can't fi...
