How Many Times Should the Air Change in my Home?

If you’re looking for ways that your home may be wasting energy, a good place to start is to find out how many uncontrolled Air Changes per Hour (ACH) are taking place in it. Air Changes Per Hour refers to how often a house completely replaces all of its air.

In this case, a higher number is not better. A lower number means less air leakage is happening in your home, so ideally you’re looking at a reading of 1 or 2 ACH. However, you will find that most homes insulated with traditional fibreglass or cellulose insulation have an ACH of 5 to 7. Do we have proof of this?  Is it from an article?

How can you help your home achieve a lower ACH? One way is to replace your traditional home insulation with spray foam insulation like Icynene. Icynene foam insulation will help to seal existing holes in your home where air may be leaking, leading to  a higher ACH level.

Potential sources of air leaks include the following locations:

  • plumbing entries
  • ducts
  • electrical outlets
  • fireplaces
  • fans and vents
  • doors
  • windows
  • walls, floors  and ceilings

Using foam insulation to seal air leaks in these locations will help to reduce the amount of air, and energy, leaking out of your home each and every hour.

Contact your local spray foam insulation contractor to find out what you need to do, to help reduce the number of Air Changes per Hour in your home.
