Air Quality Testing - Good indoor air

Poor Ventilation

Poor ventilation in any home, whether it is a detached home, semi-detached residence or condominium apartment unit can lead to a build up of air pollutants such as dust, gases, chemicals and humidity.  Over time this can cause a variety of negative health issues.  Poor ventilation can also lead to an increase in CO2 (produced by people breathing) which causes headaches, nausea, irritability as well as odour perception and a feeling the there is something wrong with the indoor air quality.

Odours indoors are usually an indicator you're not getting enough fresh air.

Airborne Particulate

Airborne particulate can include bioaerosols (mould, bacteria and viruses) as well as household dust.  These can come from the HVAC system or ducts, vacuum cleaners, poor furnace filtration as well as contents and furnishings in the room or home.  Not all air filtration devices work as advertised.  In some cases air filtration devices and air filters actually pollute the home.  Air quality testing should include testing vacuum cleaners and air filtration devices to ensure they don't pollute the air.  An abundance of particulate can cause a variety of breathing and respiratory issues.

Do you have lots of dust settling on furniture?



Volatile Organic Compounds can be emitted by decorating materials such as paint, adhesives and flooring as well as furniture and contents.  VOC testing is not always required but might be important in the case of a noticeable odour.

VOC's can be dangerous to your health or could just be a nuisance.  A VOC laboratory test can determine if the odour you smell is harmful.


Mold growth indoors can cause a variety of serious health issues for children, the elderly or a patient recovering from lung disease or any illness that can affect the immune system.  In some cases the mere presence of certain species of mold can be dangerous to your health.  In most cases a mold growth issue and resulting airborne mold spores are hidden with no sign of mold growth or musty odour.  

If you have had any history of excessive moisture or water leaks, a mold inspection is highly recommended.



Bacterial issues in a recovery area can be extremely problematic for any patient.  Serious infections and negative health issues can exist in a recovery area that have a bacterial infestation.  An Indoor air quality test can determine these problems.

Our Indoor Air Quality Testing Process


Our job is to determine if you have good indoor air quality or poor indoor air quality.

  1. We start with some background information about your home and how you have been feeling when in the home.
  2. We then perform a detailed visual inspection of the home for sources of poor air quality.
  3. We use calibrated instruments to check for temperature, relative humidity, carbon monoxide, carbon dioxide, VOC's, formaldehyde and airborne dust and particulate.
  4. We can also send air samples to laboratories to see what is in the airborne and settled dust(fibres/mould).
  5. We also use moisture meters and a thermal imaging camera to test for hidden moisture issues.
  6. We issue a detailed and easy to understand and implement written report on how to improve your indoor air quality. 
  7. We then follow up with you to answer any questions you may have.
