Do Your Home’s Ventilating Fans Work to Your Advantage?Published on: July 25, 2012
Well-insulated homes allow heating and cooling systems to work more efficiently, saving you money on energy bills, but tightly sealed homes can affect adversely affect indoor air quality too. Indoor air can be many times more polluted than outdoor air, according to the Environmental Protection Agency (EPA). Ventilating fans are an essential component of an effective HVAC system. HVAC systems that provide proper ventilation not only increase the energy efficiency of your home but improve indoor air quality as well.
Improving Indoor Air Quality
A home ventilation HVAC system improves indoor air quality by bringing outdoor air inside to dilute production of indoor air pollutants and by moving the pollutants outside of your home. Ventilation is essential in countering humid indoor air as well. High humidity levels in your home promote the growth of mold, mildew and bacteria, impairing your home’s indoor air quality. An inadequately ventilated home can aggravate allergies, asthma and respiratory conditions.
Bathroom Ventilating Fans
Ventilating fans are indispensable appliances for controlling the humidity of home bathrooms. A broad selection of models ensures the best choice for each bathroom. An ultra-quiet fan is a good option for a master bathroom. A louder fan provides some privacy for powder rooms located near public areas. Hard-working fans are essential for busy family bathrooms. Operating options include fans with humidity sensors for automatic operation, fans with timers that allow the units to keep running for a few minutes after you’ve left the room and fans with motion detectors that trigger operation when someone enters the room.
In the heat of summer, attic temperatures can reach as high as 150 degrees. A cooler attic allows your HVAC systems for work more efficiently, significantly reducing cooling costs. Attic ventilating fans help cool attics by drawing in outside air through soffit and gable vents and pushing the air outside. In winter, a cold attic helps prevent snow from melting and then re-freezing into ice dams in your home’s gutters. If your roof has asphalt shingles, attic ventilation may be required to validate the product’s warranty.
Whole-Home HVAC Systems
Another option for home ventilation is an in-line ventilation system. In-line home ventilation systems use insulated ductwork that connects with household ventilating fans and exhaust hoods in bathrooms and kitchens. Ducts direct air to a fan located in remote location such as the attic. Because the motorized fan is located away from living areas, whole-home ventilation systems are whisper quiet.
