Air Quality and Ventilation


As we improve the energy efficiency of our homes with added insulation and vapour barriers we are trapping moisture and pollutants inside so it is necessary to provide adequate ventilation for a healthy indoor climate. We need to provide oxygen for occupants since people deplete oxygen as they breath and remove contaminants – because along with the toxins emitted by the human body (ammonia, benzene, carbon monoxide and methane to name but a few), chemicals in building materials and furnishings continue to off-gas for many years after installation.

You can reduce ventilation costs with a vanEE heat recovery ventilator (HRV) or energy recovery ventilator (ERV) which use heat in outgoing exhaust air to warm incoming fresh air in the winter and eliminate excess humidity without mixing the stale air and the fresh air. For more information about these options see

In addition to ventilation there are many options for improving your indoor air quality: humidifiers, dehumidifiers, high efficiency pleated filters, electronic air cleaners, hepa filters and ultra-violet disinfection

Carrier’s award-winning Infinity air purifier doesn't just filter air: it traps and kills bacteria, viruses, mold spores, allergens and other pollutants in the conditioned air—and keeps them out of the air your family breathes. This whole-house air cleaner also re-purifies circulated indoor air as many as 8 times an hour.

With our custom sheet metal shop and licensed sheet metal mechanics we are well equipped to design a ventilation system to fit your needs.
