As cold weather settles into Maryland, homes in Edgewater, Annapolis, and throughout Anne Arundel County are sealed tight to preserve warmth. But with closed windows and frequent HVAC use, indoor air quality often takes a hit. Trapped dust, pet dander, and low humidity can all contribute to poor respiratory health, especially for allergy sufferers. That’s why knowing how to reduce indoor allergens during the heating season is essential for comfort and well-being.
Why Winter Air Quality Suffers in Maryland Homes
During winter, we naturally close windows and run our heating systems longer. While this keeps us cozy, it also limits ventilation and recirculates existing indoor pollutants. With nowhere to escape, allergens like dust mites and pet dander concentrate inside. In homes with pets, carpeting, or older ductwork, these issues become even more pronounced.
Recognizing Allergy Symptoms Indoors
Indoor allergens are often invisible, but their impact is easy to feel. Common symptoms include:
- Persistent sneezing and congestion
- Itchy eyes or throat
- Worsening asthma symptoms
- Fatigue or headaches that improve when outdoors
If these symptoms worsen in the winter, poor indoor air may be to blame.
Pet Dander and Indoor Air Quality in Winter
Even the most beloved family pets can be a source of indoor air quality issues, especially when windows stay closed. Pet dander is made up of microscopic skin particles that easily float through the air and settle on furniture, vents, and bedding. During winter, this dander accumulates more rapidly due to reduced ventilation and less outdoor time for pets.
Managing pet dander involves more than just frequent cleaning. Investing in high-efficiency HVAC filters and regular duct maintenance can significantly reduce airborne particles. Keeping pets out of bedrooms or using air purifiers in common areas can also help allergy-prone family members breathe easier.
How HVAC Systems Can Help or Hurt
Your heating system plays a major role in how allergens move through your home. Dust and dander trapped in vents or filters can easily recirculate when the system runs. If your HVAC system hasn’t been cleaned or inspected recently, it may be contributing more to your allergy symptoms than you think.
Regular filter changes, professional duct cleaning, and system tune-ups can turn your HVAC into a tool for reducing indoor allergens during the heating season.
Cleaning and Dust Control Strategies
Keeping allergens in check starts with limiting dust and its ability to circulate. In homes with central heat, even small changes can make a noticeable difference in air quality. Targeted dust control efforts include:
- Vacuuming with a HEPA-filter vacuum at least twice per week
- Using microfiber cloths for dusting rather than dry rags
- Washing bedding weekly in hot water
- Placing mats at entryways to trap outdoor pollutants
For Maryland homes with older ductwork or high dust accumulation, a professional HVAC inspection can help identify areas that need deeper attention.
