We're Indoor Air Quality Experts

  • Indoor Air Quality (IAQ) has become an important health and safety concern for Canadians.  The most common issue associated with IAQ is improper or inadequately maintained heating & ventilation systems.​

  • Issues that lead to poor IAQ can include inadequate temperatures, humidity, poor air circulation, ventilation issues, insufficient outdoor air intakes & indoor air contaminants such as chemicals, dust, moulds or fungi, bacteria, odours & vapours.

  • Poor IAQ can lead to various symptoms such as: dryness & irritation of the eyes, nose throat & skin, headaches, fatigue, shortness of breath, hypersensitivity, allergies, sinus congestion, coughing and sneezing, dizziness and nausea.  ​
