Why Indoor Air Quality Matters More During Heating Season

As the heating season gets into full swing, Central Oregon homeowners face more indoor air quality (IAQ) concerns. Recirculated air, closed windows, and a dry climate can significantly impact your comfort and health. By investing in indoor air quality this heating season, you can prevent respiratory issues, alleviate allergies, and boost your home’s humidity.

How Heating Season Affects Indoor Air Quality

When the heating season arrives, there are a few factors that combine to impact air quality in Redmond and Bend homes.

First, heating season air quality is negatively impacted because there’s reduced ventilation. Windows are kept closed because of the weather, which causes air to recirculate. In turn, this makes indoor pollutants build up. Additionally, the furnace’s normal operations cause the airborne particles to spread throughout the home.

Common Indoor Air Pollutants During Winter

In the Bend, Madras, and Redmond area, there are a few indoor air pollutants that are more common during the winter.

• Dust
• Pet dander
• Mold spores
• Pollen tracked indoors
• Bacteria and viruses
• Combustion byproducts

Health Effects of Poor Indoor Air Quality

Around the world, indoor air pollution leads to around 2.9 million deaths per year. Over time, indoor air pollution can increase the likelihood of asthma, emphysema, and other respiratory diseases.

Even in the short run, poor indoor air quality can lead to significant health effects. Allergy flare-ups, dry skin, sinus problems, and dry eyes are frequent issues. Additionally, many people experience fatigue and headaches when the indoor air quality is poor.

Dry Winter Air and Its Impact on Comfort

Because of our high desert climate, it’s normal to deal with dry air in the winter. While part of this is due to the dry outdoor air, indoor factors also play a major role.

When air temperatures drop below freezing, the air has a lower capacity to hold water. As a result, you’ll automatically experience drier air as the temperatures drop.

Once it gets cold out, heating systems get switched on. The increased temperature means that the air has a higher moisture capacity. Thanks to the higher capacity, the air actually pulls moisture from any available source. Wood furniture, skin, lips, and nasal passages can quickly become dried out.

In addition to drying out your skin, wintry weather can increase the likelihood of static electricity. Normally, water molecules in the air serve as conductors so that energy can dissipate. When the air dries out, the static electricity doesn’t have any way to disperse. As soon as you touch a doorknob or a freshly laundered sweater, the charge buildup is able to jump into your body.

While dry air is most noticeable during winter, seasonal changes can affect your indoor air quality year-round. For more seasonal tips, check out our guide on improving indoor air quality in spring and summer.

Why Homes in Central Oregon Are More Affected

When it comes to indoor air quality in winter, there are a few major reasons why Central Oregon homes are significantly impacted.

• High Desert Climate: In our high desert climate, the air can get dry. The colder nights also result in more heating usage. Because of low humidity, the level of indoor air pollutants is concentrated.
• Sealed Homes: As winter sets in, the temperatures get cold. To lower the cost of heating homes, architects make local homes well-sealed and insulated. This sealing locks contaminants indoors, worsening indoor air quality in Central Oregon.
• Increased Furnace Runtime: When furnaces run for extended periods, they contribute to dry skin and respiratory issues. The added air circulation also causes allergens and indoor pollutants to move throughout your home.

How Your Furnace Impacts Indoor Air Quality

While the environment and climate play a major role in determining your indoor air quality during the heating season, your furnace affects it as well. When the air filter is dirty, it allows contaminants to get into your HVAC system and inside your home. Additionally, dirty air filters can lead to overheating and cause premature wear.

Over time, ductwork can collect dust and debris. When your heating system switches on, the air flows through the ducts and blows all of the dust into your home.

If you don’t have an air purifier for your furnace, it could be making the situation worse. A lack of purification allows the buildup to continue, worsening your indoor air quality.

Ways To Improve Indoor Air Quality During Heating Season

There are a few IAQ solutions you can use to enhance your indoor air quality.

Regular Filter Changes

One of the most important things you can do to protect your HVAC system and respiratory health is to change your air filter. Ideally, the air filter should be replaced every 30 to 90 days to prevent dust and debris from getting into your system.

Whole-Home Air Purifier

When homes are sealed up in the winter, a whole-home air purifier is an excellent way to filter contaminants out of the air. Depending on your goals, you can install a HEPA air purifier, a UV purifier, an activated carbon air purifier, or an ionic air purifier. For example, UV air purification can reduce the amount of mold, bacteria, and other pathogens in the air. Meanwhile, a HEPA air purifier is effective at removing allergens, dust, wildfire smoke, and pet dander.

Humidifiers

Dry air can lead to chapped lips, dry skin, and respiratory issues. To boost your comfort and indoor air quality during the heating season, you can install a whole-home humidifier.

Duct Cleaning

Periodically, you should have your ductwork cleaned. The HVAC technician can discuss the type of HVAC maintenance you need and any ductwork recommendations.
