Fresh air intakes, for the provision of combustion air for heating appliances, are not necessary for electric furnaces. These are normally installed near an older natural-gas furnace or hot-water heater to ensure adequate air for combustion. These intakes are usually composed of long, insulated, flexible ducting installed with a loop near the bottom. This loop is designed to provide a partial trap, reducing the amount of cold air intrusion until it is needed by the heating devices. Regardless of the lack of necessity for combustion air for homes heated with electric furnaces, bringing in a good source of fresh air may be equally or more important than for homes heated with gas. Homes with older, naturally aspirated furnaces and water heaters have large chimney flues or vents installed t...

A loud clicking noise starts whenever I depress the brake pedal. There is no clicking noise when I am driving. I drive to work through a quiet area of the city and am able to go slow (50 km/h) with all windows down and there is no noise when I am driving, either coasting or with the gas pedal pressed. When I have to brake, the moment I depress the brake pedal, the clicking begins and then stops completely when the car is stopped. I can hear the clicking from the left front window coming from the left front. A passenger seated in the front passenger seat also advised that the clicking can be heard from the right front side. I have had the car to the dealership and the brakes are inspected, but no fault can be found. The service writer said to me that on occasion, a stone gets lodged betw...

Most older homes would have one or more chimneys that allowed a considerable amount of air to pass through the building envelope, ensuring plenty of fresh air to prevent negative pressure when exhaust fans are turned on. In your case, the new high-efficiency furnace has a partially sealed combustion chamber and a direct vent and fresh air intake system, just for the furnace. Also, you likely have an electric hot water heater and no need for a chimney. Eliminating the chimney and replacing it with the direct vents for the furnace removed one large opening in the building envelope. This factor will help with prevention of heat loss and save energy, but may also help a negative-pressure situation develop within your home when the dryer or central exhaust fan forces air outside. Now that th...

These ventilation systems have a decorative exterior hood that hides the works and an exhaust fan and ductwork to extract the air, smoke and moisture. Obviously they need to be over the cooking area -- ideally they should extend over the stove's surface area. They need to be close enough to the stove to extract air, but not so close you can't comfortably cook. If they are too high, like many 'designer' hoods, they aren't doing an effective job. Kitchen exhaust fans come in different sizes and need to be appropriate for the size of your stove and house. It's very important that you get the correct size of ventilation fan. It's not as simple as 'bigger is better.' Most new homes are pretty airtight -- that's one of the reasons we have few problems with indoor air quality and mould growth....
