Have you ever wondered how much air actually comes out of your hot air floor registers, or how many cubic feet per minute your bathroom fan actually exhausts? Well the Canada Mortgage and Housing Corporation has developed a simple tool that will give you a good approximation.They call it the Gar...
Cory from Regina, Saskatchewan is finishing their basement and wants to know if they should have cold air returns in the basement.Hot air heating systems function best if there is at least one cold air return on each floor of the house. Essentially, that allows the warm air to circulate better. ...

In fact, on the average, measured volumes were 44% of rated flow for bathroom fans and 38% of rated flow for kitchen fans. The primar...
