6 Facts You Don’t Want to Hear About Your Home’s Air Ducts

March 14th, 2013

Air ducts. To the average Northern California home owner, they’re invisible.

Your furnace and air conditioner heat and cool the air and blow it into your home. You forget the middleman – your ductwork.

But your air ducts are extremely important to the your heating and cooling system’s energy efficiency and your comfort.

To prove our point, here are 6 facts you probably don’t know and don’t want to hear (but should) about air ducts.

Your Air Ducts Lose 20% of Your Heated and Cooled Air

ENERGY STAR estimates that in a typical house about 20% of the air that passes through air ducts is lost.

In addition, studies by PG&E state that “faulty ductwork accounts for nearly 25% of the heating loss in an average California home.”

Air ducts waste energy when they have:

  • Insufficient insulation
  • Holes and cracks
  • Missing seals around vents and connections

Your Air Ducts Could Be Responsible for Your Dirty Home

Does it feel like your home is always dirty? Even after you just dusted from top to bottom, you notice a fine layer of dirt on your furniture. You’re not crazy – your air ducts may be to blame.

Leaky ductwork allows dirt and debris to enter your home from the attic, walls and crawlspace.

Your Air Ducts May Be Suffocating Your Air Conditioner and Furnace

Many homes do not have an adequate amount of return air ducts (the ducts that pull air from your home and return it to your heating and cooling system.)

This suffocates your air conditioner and furnace because they cannot receive enough air, resulting in higher energy bills for you. Learn more about the importance of airflow in our previous blog post.

You Should Never Use Duct Tape on Your Air Ducts

You would think air ducts and duct tape would go together like hot dogs and hot dog buns. Sadly, this isn’t true.

Duct tape is not long-lasting. If you are making repairs on your leaky ductwork, you should use a mastic sealer, which is a long-term solution.

Air Duct Design is Extremely Important to Your System’s Efficiency

Think of your air ducts like roads and the air like vehicles trying to get to their destination (your home.)

If the roads are in disrepair (holes, cracks, etc.), you’ll lose some of the travellers. If the roads are longer than they need to be, you’ll lose efficiency. If the roads are too narrow, you’ll be stuck in rush hour.

(Ducts that are too big are also a problem. No analogy is perfect.)

So, if you want to improve the energy efficiency of your home’s heating and air conditioning system, you may want to have someone check out your ductwork.

Your Air Ducts Could Be Hiding Dangerous Contaminants

Over time, your air ducts collect dust and debris, just like your furniture. But you can’t easily get to the inside of your ducts, so the dirt just builds up.

In some cases that means, in addition to dust, your air ducts are housing dangerous contaminants like mold, mildew, bacteria and viruses, which are circulated throughout your home whenever you run your system.

Cleaning your ducts and installing a good air filter can help.
