There are many things to consider when installing a bathroom fan, but when we went to install one in a viewer's home, we were stopped short when we discovered that the old one had no duct at all attached to it. It just shot right into the attic. You must get that hot moist air beyond the at...
I hope you all realize by now that what is called "duct tape" is not very useful for ducts because it ages and falls apart so quickly. The only really good duct tape is aluminum duct tape. But how many of you have struggled with how to get the backing paper off, or at least, how to get it s...
Many years ago, because of the prairie enforcement of the gas code provision that you had to supply fresh air to a furnace, an inventor in Alberta began marketing the Hoyme damper. This is a motorized damper that closes off that combustion air duct from the outdoors that dumps cold air into ...

When you use a hole saw, it is often very difficult to get the plug out of the saw cup when you are done. More and more manufacturers have provided slots on the side of the hole saw to allow you to jam a screwdriver in and pry the plug out. But this is often not so easy. (By the way, the larger t...
Air-change ventilation systems exist that take stale air out and bring fresh air in so as to not rely on cold air drafts for the entry of fresh air to the house. They are simply a box with two fans. In a few of the warm spots of Canada these are legitimate systems on their own. In most of Canada ...
