How Winter Affects Your Ventilation System

Ventilation is critical at any time of year, but winter is particularly challenging. You probably spend more time indoors hiding from the chill so opening a window isn’t an option. Between the flu season, regular allergies, and just the need to breathe fresh air, ventilation is critical during winter. Here are six considerations at this time of year.

Cold and Flu Season

Because winter is nearly synonymous with sniffles and sneezes, ventilation plays a major role in keeping your family healthy during this time. Recirculated air keeps the germs inside, spreads it to everyone and reduces your body’s ability to fight it off. You might get away with a less than robust system in the summer when you can open windows, but winter illness requires better ventilation.

Temperature of Outside Air

Fresh air coming in needs to be heated, so the place where it enters your house matters. If your ventilation system consists of exhaust fans and infiltration , you’ll have lower temperatures to get the fresh air you need.

Humidity

When outdoor air is heated without the addition of moisture, the relative humidity drops. This dries out your indoor air . You’ll experience dry mucus membranes (increasing susceptibility to colds and flus), static buildup, and possible damage to electronics, wood floors and cabinetry.

Energy Consumption

Outdoor air requires energy to heat and humidify. The energy consumed is highest for air that’s directly heated, whether ducted to your furnace or entering through construction gaps. Energy recovery allows you to reap the benefits of fresh air without the cost of excessive energy consumption.

Vulnerable Family Members

If you’re concerned about energy costs, then aim for an energy recovery system rather than attempt to avoid ventilation., altogether. It may be tempting to keep exhaust fans off and find ways to prevent or minimize ventilation, but you’ll pay for it in other ways, especially if you have family member with allergies or who are prone to illness.

Dust

Dust is not just a summer problem; particulates can cause problems during winter as well. Ensure you have the right filtration in place and maintain it. Change filter regularly and monitor the source of your outside air.
