Effective and efficient mechanical ventilation is an important part of a healthy indoor environment.

Improved insulation and other energy-saving measures have meant poorer air circulation for many homes and buildings. Scientific research shows that indoor air can be up to 5 times more polluted than the air outside. Moisture build-up can also cause a variety of ills to the materials with which your home is built

We can help determine if your home or building is prone to indoor air pollution problems due to organic resins or vapors, poor air turnover or high humidity. With proper ventilation and air circulation, a building can maintain excellent air quality that can help improve the health of those inside.

Today's homes are so well insulated that they trap humidity and pollutants indoors. Result: Over 50% of homes show visible signs of humidity. However, it is possible to breathe fresh air inside as if you were outside and fully enjoy your home.

Daily activities such as showering or washing dishes release moisture into the air. Over time, if this moisture cannot be evacuated, its accumulation will cause mold build up, unpleasant odors and costly damages to the house structure often in hidden places. When discovered, it is already too late
