How to Upgrade Your Kitchen Ventilation

How to Upgrade Your Kitchen VentilationHow’s the ventilation in your kitchen? Consider yourself lucky if your kitchen range is ventilated to the outdoors. That’s the best way to get rid of irritating smoke and water vapor, which can add humidity in your home, making you feel uncomfortable and even causing issues with mold and mildew. If you don’t have adequate kitchen ventilation, maybe it’s time to look into it.

Types of Kitchen Ventilation

The most favored type of kitchen ventilation is of the updraft design. These use a blower to inhale cooking vapors, then push them through a duct which, we hope, exhausts the vapors through the roof rather than the attic. These are likely to be in the form of hoods or canopies, purchased separately from the stove.

The downdraft type draws cooking vapors across the surface of the range, and down through a duct that exhausts to the outdoors. These are likely to be integrated into the cooking appliance’s surface. The main drawback in using them is that they do not rise more than 10 inches above the surface of the range, and so cannot capture steam from a tall pot. They are usually chosen when they are to be incorporated into an island where the homeowner doesn’t want a view blocked, or in a kitchen with a high ceiling, where ductwork would be too high to work effectively in the updraft model.

Whichever type you choose, be sure that it can move the volume of air you will need to move in relation to the heat output of your range. Your ventilation specialist can help you calculate this.

Installing Kitchen Ventilators

If you have an older house, you may already have ducts in place that can accommodate the installation of new, upgraded kitchen ventilation. If the ductwork isn’t in the right position to accommodate a new range hood or canopy, you will have to move it. Unless you’re an accomplished DIYer, you may need a ventilation and ductwork specialist to advise you on installation.

Ventilation: Keeping Your Home’s Air Fresh

Ventilation: Keeping Your Home's Air FreshAdequate home ventilation plays a significant role in your family’s health, during the heating season when all the doors and windows are closed. Indoor air pollutants build, especially in energy efficient, air-tight homes, that can cause mild to serious illnesses.

Increasing the amount of fresh air indoors reduces bad air quality that may come from:

  • Volatile organic compounds (VOCs) that come from common household products. Burning candles, using perfumed soaps, air fresheners, dryer sheets or cleaning products introduce potentially harmful VOCs, as do home improvement products like flooring, furniture and upholstery fabrics.
  • Combustion byproducts from gas stoves, malfunctioning furnaces or gas dryers, or exhaust fumes and VOCs entering through small air leaks from an attached garage.

Keeping the air fresher is possible by using:

  • Kitchen and bathroom fans. Whenever you use a gas stove or oven, turn on the exhaust fan as long as it vents outdoors. A re-circulating fan just blows the gases back into the kitchen.
  • Use bathroom fans to remove excess humidity while and after showering. Running all the ventilating fans at once also helps clear the air after using products high in VOCs.
  • Supply-only fans. Window fans and whole-house fan pull fresh air in directly. They’re an excellent solution when outdoor temperatures are comfortable enough to bring indoors, although they introduce allergens when pollen counts outdoors are high. Using them when it’s cold outside increases heating costs.
  • Balanced ventilation systems. These types of mechanical systems combine the benefits of removing stale indoor air and replacing it with fresh air without changing the indoor temperature. They use innovative technology that exchanges the thermal energy of the outgoing air and puts it into the incoming air.
  • Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) deliver fresh air into your home’s forced-air HVAC system or direct it into a specific room or area. They’re the most energy efficient and effective way to improve air quality year-round.

Fresh air ventilation is essential to good health the enjoyment of your home. To learn the best options for your home, contact Roth Heating & Cooling, providing trusted HVAC services for Portland-area homeowners.
