Why Your Home’s Ductwork Could be Leaking Money

November 25, 2014

Yes, money. Possibly $200 to $300 every year.

How?
 
Because your ducts are leaking out too much air! 
 
According to ENERGY STAR, the typical home loses 20% to 30% of air moving through the ductwork because of “leaks, holes, and poorly connected ducts.”
 
That means your heating and cooling system could be running 20% to 30% longer to heat and cool your home. (The typical family pays about $1000 a year on heating and cooling, so that’s where we got the $200 to $300 numbers).

3 signs you have air duct leaks

While most homes have air ducts leaks, some homes have it worse than others.

You’ll know if your home’s ductwork is a mess if you notice these signs:

  • High energy bills
  • Some rooms are harder to heat or cool than others (Has anyone in your home complained that their room just isn’t comfortable? Might be a duct leakage problem.) 
  • High humidity levels in your home (if the leaky ducts are located in the attic or crawl space)

Does that sound like your home? Read on.

How to fix leaky ducts: duct sealing

You can either: 

You’ll need a professional’s help if the leaks are hidden in walls and ceilings—places you can’t easily access.
 
But there are some easy-to-access areas you can check and seal yourself.
 
The most important ducts to seal are the one’s nearest to your furnace’s blower. That’s where pressure is highest, so there could be tons of air escaping the return and supply ductwork. 
 
Here’s how you can seal your air ducts yourself:
 

  1. Buy some air duct mastic sealant.
  2. Turn on your heating system.
  3. Feel around the air ducts nearest your furnace. If you feel hot air escaping, you’ve found the leak.
  4. Apply the mastic sealant like in this video.
