Including a ventilation system as a central mechanical component to the whole house air control network is priority one when concerned about indoor living comfort with a healthier environment while protecting your home resale value.

With a properly designed and installed ventilation system, the home is protected against excess moisture causing mold and mildew.  Each building dictates its own particular design considerations which are best addressed by a ventilation professional.  (see Lee's bio) These can include heat loss calculations and ventilation correction rates for certain conditions.

To achieve this goal in your home, it is a priority to design and install a ventilation system which meets the current Ontario building code requirements for new home construction.  Various options are available regardless of the age of the home.  

The unit best suited to your needs will be determined by one of the following primary concerns;

1. Addressing air quality concerns related to allergy/health issues.
    
2. Addressing structural deterioration caused by excess moisture levels. 

As you seal up your home to conserve energy costs, you also entrap pollutants that cause general poor air quality.  Each concern can be alleviated by timely intervention with the correct mechanical system.
