High utility bills ? Cold rooms ? Dusty house ?

It could be your home’s duct system. Frequently misstated as duck system, it is a main artery of your breathing home. 

In homes with forced-air heating and cooling systems, as typical in Alberta, ducts are used to distribute conditioned air throughout the house.  A duct system that is properly sealed and insulated can make your home more comfortable, energy efficient, and safe—all while helping to reduce your energy bills. However, in typical homes, typically 30 percent (sometimes as high as 50 percent) of the air that moves through the duct system is lost due to leaks, holes, and poorly installed ducts, never getting to its intended location.  A typical home furnace provides 700-1200 CFM (cubic feet per minute) of air to distribute to the house; many duct systems leak as much as 500 CFM – imagine a 9 x 10 inch hole in the duct just above your furnace venting air that was meant for your bedroom, playroom or home office. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.

Benefits of Properly Sealing and Your Duct System

$$$ Savings on Utilities

Sealings your ducts reduces your utility bills by 30%.  Alberta electricity (used for both your natural gas furnace and air conditioner) prices are forecast to double within foreseeable future.  Leaky ducts can reduce heating and cooling system efficiency by as much as 50 percent. Sealing ducts increases efficiency, lowers your energy bills, and pays for itself in energy savings.  

Improved Comfort

Sealing ducts helps with common comfort problems, such as rooms that are too hot in the summer or too cold in the winter.  

Cleaner Home and Better Indoor Air Quality

 Sealing ducts can also help improve the indoor air quality by reducing the risks of pollutants entering ducts from dusty attics, walls or musty crawlspaces and re-circulating through your home. Dust from insulation particles or smells from damp spaces could aggravate asthma and allergy problems.

Improved Safety

 During normal operation, gas appliances such as water heaters, clothes dryers, and furnaces release combustion gases (like carbon monoxide) through their ventilation systems. Leaky ductwork in your heating and cooling system may cause “backdrafting,” where these gases are drawn back into the living space, rather than expelled to the outdoors.  Sealing leaks can minimize this risk.

Eliminate 3 tons/year of CO2

The less energy you use in your home, the less air pollution is produced.  By sealing your ducts and reducing the amount of energy necessary to comfortably heat or cool your home, you can have the peace of mind that you’ve done the right thing for your family, home, and for the planet. 


Easity Improve Your Duct Performance

Ducts are typically concealed in walls, ceiling, attics, basements and crawl spaces thus are tricky and costly to repair, not to mention disruptive to your home as require opening walls. Using conventional construction systems still leak 10-15%.

An innovative product now allows Duct Sealing From the Inside. Endorsed by This Old House and Mike Holmes, Aeroseal is a safe, aerosol-based technology that easily seals your home’s ducts, reducing system leaks typically by 95%.
