Following the energy crisis of the 1970s, we tended to insulate our homes and make them airtight.

The results? Our homes are more economical to heat and cool because heat losses and infiltrations are reduced to a minimum.

The consequences? Everything produced inside the home remains inside and accumulates resulting in the deterioration of indoor air quality.

More and more illnesses are associated with poor indoor air quality.  We have only to think of the growing number of asthma and allergy cases. The air we breathe is contaminated by all types of gases, dust, and bacteria. In addition, we consume oxygen and produce gases and humidity, while not renewing the oxygen consumed. Here are just a few examples of product that contaminate the air we breathe.


  • Rugs
  • Furniture
  • Animals
  • Linen


  • Bathroom
  • Kitchen
  • Basement


  • Household cleaning material
  • Paint
  • Cosmetics
  • Glue

Have an old or existing home?

Ventilation is still not a problem as we can design ventilation systems for any new or existing home and would be happy to visit your existing home to advise you of the possibilities.

A residential heat recovery ventilator uses separate motors to exhaust stale ambient air and to introduce fresh outdoor air. The technology of a plate heat recovery core is that it transfers warm ambient air from one airstream to the other without mixing the air streams for maximum efficiency and comfort.
