Why should I have my air ducts cleaned?

• Air ducts naturally accumulate sizeable deposits of dust and other contaminants over a period of years.
  
  
• Dirt deposits can reduce the efficiency of your heating and air conditioning system and even cause physical discomfort and illness by degrading the quality of air you breathe indoors.
  
  
• Dirt deposits in your air ducts actually act as food for organisms such as dust mites.

Contaminates build up inside the return ductwork. Traditional heating and cooling systems recirculate the air in a home via supply air ducts and return air ducts. Many homes have inefficient filters, which trap less than 10 percent of the particulate that is circulated in the system. If not trapped by the systems air filter, the particulate accumulates in the duct work and on the internal components of your furnace or fan coil.

Cleaning your duct work eliminates these contaminates with the following benefits:

• Safeguard your health by eliminating potential causes of allergies and respiratory problems.
  
  
• Eliminate the dirt that acts as food for dust mites, bacteria, mold and other micro organisms.

What type of procedure does Smith Electric HVAC, Inc. use to clean my system?

We employ and train highly competent individuals to best serve the needs of our customer. Upon arriving at your home our lead technician will explain the process to be used in cleaning your system. Source removal duct cleaning is considered the best method for relieving indoor air quality problems and is the only method endorsed by the National Air Duct Cleaners Association (NADCA).

We use the ROTOBRUSH system to clean your ducts. This uses a high volume vacuum system with an assortment of rotating brushes to dislodge contaminates and pull them from your home. All grills, registers, diffusers and plenums are cleaned and sanitized. After the cleaning, an EPA approved sanitizer is fogged through the system. This sanitizer will kill mold, bacteria and fungus.

To help ensure a clean, healthy environment, we recommend that air ducts be cleaned every 5 to 7 years.

Smith Electric HVAC Inc. offers duct leakage testing and sealing.

We can do a blower door test on your house to determine air leakage on the house and on the duct.  We temporarily install a “blower door” in an outside doorway of your home.  With this we can pressurize or depressurize the house and determine the amount of air leaking into or out of your house.  This is a great way to help locate leaks in your house in unexpected places.  We can also use this to determine the amount of leakage in your duct system.  Accessible duct can then be sealed and the system retested to verify the reduction on leakage.

Why seal your duct work?

• 20% - 40% of conditioned air is lost through duct leaks.


• The EPA estimates over $5 billion in wasted energy annually.


• Leaky ducts can more than eliminate saving from high efficiency units.

If you are interested in having the most efficient duct system possible, you need to learn more about this. We will be happy to discuss additional information about the procedure with you and come to your home or business for a free estimate.
