A vital system for a healthy home
All homes require adequate ventilation for the safety of their occupants and to remove excess humidity, airborne pollutants and odors. As homes across the country are built and renovated with energy conservation in mind, they are more air-tight, and the need for balanced mechanical ventilation is even more obvious.
Without fresh air, carbon dioxide, odors, dust, airborne pollutants and excess humidity are kept indoors, potentially causing or aggravating problems to occupants’ health and comfort, and encouraging mold growth.
Some of the contributing factors to poor air quality in the home are:
- Moisture – Can cause allergy problems and structural damage by encouraging the growth of molds, mildew, bacteria, dust mites, dry rot, and insects.
- Common household chemicals – Cleaning supplies, Paints and solvents, Formaldehyde from furniture, carpet, and building materials, Pesticides, Volatile organic compounds, Odors
- Particles – Dust and dust mites, Pet dander, Pollen, Lead, Asbestos
- Tobacco smoke, a health risk to smokers and nonsmokers alike. Children are especially at risk.
- Combustion products – (From fuel-burning heating equipment, gas water heaters, fireplaces, wood stoves, gas ranges, candles) Carbon monoxide, Carbon dioxide, Nitrous oxides, soot, Unburned fuel, Moisture
- Heat – Overheating in attic from sun
Clearly, effective ventilation is a vital system in a healthy home. A balanced mechanical ventilation system with heat or energy recovery is an ideal way to meet both building codes and the requirements of many energy efficiency programs such as ENERGY STAR® for New Homes, Novoclimat™, BuiltGreen™, R2000 and many more.
ERVs and HRVs prevent the buildup of stale air, pollutants and excessive moisture by moving stale air outside, bringing fresh air inside, and transferring either heat or moisture in the process to preserve your comfort.
The installation of an air exchanger inside the house will remove stale and polluted air from the house to the outside and replace it by an equivalence of fresh air, renewing the air in all the important parts of the house.
