Spring is in full swing, and while we welcome warmer temperatures and blooming flowers, we also brace for one unwelcome guest: allergy season.
For many people, pollen, dust, and other allergens can make springtime miserable. But there’s good news — your air conditioning system can help protect your indoor air quality and reduce allergy symptoms if it’s properly prepared.
Here’s how to make sure your AC system is ready to defend your home against spring allergens.
1. Replace Air Filters Regularly
Your HVAC system’s air filters act as the first line of defense against pollen, dust, and airborne allergens. Over time, filters become clogged, allowing contaminants to circulate throughout your home.
What to do:
Replace standard air filters every 1–3 months during allergy season.
Upgrade to a high-efficiency filter (like a HEPA filter) to capture smaller particles.
Pro Tip: If you have pets or suffer from severe allergies, consider replacing your filters even more frequently.
2. Schedule an AC Tune-Up
Professional HVAC maintenance isn’t just for keeping your system running—it also plays a huge role in maintaining clean indoor air. Dust, mold, and debris can build up in your AC system, reducing air quality and worsening allergies.
What a tune-up includes:
Cleaning condenser and evaporator coils
Checking and adjusting airflow
Inspecting ductwork for buildup
Ensuring optimal system performance
Pro Tip: Spring is the perfect time to schedule maintenance before peak summer demands hit!
3. Clean the Air Ducts
Even the best filters can’t prevent dust and allergens from collecting in ductwork over time. If your ducts are dirty, they’ll circulate allergens every time the system kicks on.
Why duct cleaning matters:
Removes built-up dust, pollen, pet dander, and mold
Improves system airflow and efficiency
Enhances overall indoor air quality
Pro Tip: Have your air ducts inspected every 3–5 years to determine if a professional cleaning is needed.
4. Keep Humidity Under Control
Humidity plays a big role in how allergens affect you. High humidity levels encourage mold growth and dust mites, while air that’s too dry can irritate respiratory systems.
What to aim for:
Maintain indoor humidity between 30%–50%.
Use a whole-home dehumidifier if humidity is consistently high.
Seal up any leaks around windows and doors to prevent moist air from getting inside.
5. Upgrade to an Air Purifier
For homes with allergy sufferers, adding an air purifier to your HVAC system can provide an extra layer of protection. These devices capture fine particles that standard filters might miss.
Benefits of a whole-home air purifier:
Captures allergens, bacteria, and even some viruses
Provides cleaner air throughout your entire home
Works seamlessly with your existing HVAC system
6. Seal Your Home Properly
Spring breezes are refreshing—but they can also carry pollen right into your home. Cracks and leaks around doors, windows, and attic spaces allow allergens to sneak inside, making your HVAC system work harder.
Steps to take:
Check for drafts and seal gaps with caulk or weather stripping.
Ensure that attic and crawl spaces are properly insulated.
Keep doors and windows closed on high-pollen days.
Why Preparing Your AC for Allergy Season Matters
A well-maintained air conditioning system does more than keep you cool—it also helps you breathe easier. Clean, filtered air reduces allergy symptoms, improves sleep, and creates a healthier living environment for everyone in your home.
Skipping spring preparation means allergens will circulate freely inside, making allergy season much harder to manage.
