Allergy Season and Your HVAC: Tips to Keep Allergens at Bay
Spring and early summer in Laurel and Billings are known for their beautiful landscapes, budding trees, and—unfortunately for many—intensified allergy symptoms. If your eyes are itching, your nose is running, or your sinuses feel stuffed up, you’re not alone. Montana’s allergy season can be rough, especially with rising pollen counts and frequent weather changes.
What many homeowners don’t realize is that your HVAC system can be your best defense—or your worst enemy—when it comes to indoor allergens. Here’s how to make sure your system helps you breathe easier this allergy season.
1. Change Your Air Filters Regularly
Your HVAC system’s air filter is the first line of defense against pollen, dust, pet dander, and other allergens. During allergy season, filters can become clogged quickly, circulating irritants rather than removing them.
Tip: Replace or clean your air filter every 30 to 60 days, or more often if you have pets or severe allergies.
Upgrade to a HEPA or high MERV-rated filter for better particle capture.
At Patriot Heating and Cooling LLC, we can help you select the right filter type for your home and air system to balance efficiency and allergen control.
2. Schedule a Professional HVAC Cleaning
Dust, mold, and pollen can build up inside your ductwork, vents, and coils—especially after a long winter with the heat running constantly. A professional cleaning ensures your system is running clean and won’t circulate allergens every time it kicks on.
Clean air ducts, evaporator coils, and blowers
Remove mold or mildew buildup that could be hiding in your system
Reduce the spread of airborne irritants throughout your home
Our experienced techs offer full HVAC inspections and cleanings right here in Laurel and Billings, customized to your system’s needs.
3. Use a Programmable Thermostat to Control Humidity
Montana’s dry climate may not scream “humidity problem,” but seasonal changes and poor ventilation can create pockets of dampness, especially in basements or poorly insulated spaces. Dust mites and mold thrive in humid environments.
Set your thermostat to maintain indoor humidity between 30–50%
Consider installing a whole-house dehumidifier if moisture is a recurring issue
Use bathroom and kitchen fans to vent humidity at the source
Newer smart thermostats can automatically monitor and adjust humidity levels—something we’d be happy to help install or configure for you.
4. Seal and Insulate Ductwork
Leaky ductwork can pull in dust, pollen, and allergens from unconditioned spaces like your attic or crawlspace. Not only does this lower indoor air quality, but it also reduces your system’s efficiency.
Have your ductwork sealed and insulated professionally
Prevent allergens from entering your airflow from dirty or dusty zones
Improve overall comfort and air quality
This small fix can make a big difference—especially during peak allergy season in Billings and Laurel.
5. Consider an Air Purification System
Sometimes filters and cleanings aren’t enough. If your allergies are severe, an additional air purification system could be the solution.
UV lights inside your HVAC system kill bacteria and mold spores
Ionizers or air scrubbers neutralize airborne pollutants
Whole-home purifiers work with your HVAC to clean the air in every room
We offer affordable installation options for homes of all sizes, and our team can recommend the right product based on your air quality goals.
