Ways to Reduce Home Allergens with Preventive HVAC Maintenance

September 11, 2025

As summer comes to a close here in Arkansas, allergy season is still in full swing. Ragweed pollen, dust, and lingering humidity can all take a toll on your indoor air quality. If your HVAC system isn’t maintained properly, those allergens can easily circulate through your home and make your symptoms worse.

At Mohr Air Conditioning, we know how important clean, comfortable air is for your family. That’s why preventive HVAC maintenance is one of the best tools you have to reduce allergens and keep your system running smoothly as we head into fall.

1. Replace Air Filters Regularly

Your HVAC filter is your first line of defense against allergens. Over time, filters collect dust, dirt, and pollen. If they’re not replaced often enough, they get clogged and lose their effectiveness.

• Tip: Replace your filter every 1–3 months, depending on your system use and whether you have pets.
   

• Why it matters: Clean filters trap allergens before they spread throughout your home.
   

2. Keep Air Ducts Clean

Air ducts move conditioned air throughout your home, but they can also collect dust and debris. Dirty ducts may circulate allergens back into your living spaces.

• Tip: Have your ducts inspected during seasonal maintenance.
   

• Why it matters: Clean ducts improve airflow and reduce allergen buildup.
   

3. Maintain the Evaporator Coil and Drain Lines

Moisture from cooling can lead to mold and mildew growth inside your system if not properly drained. Mold spores are a major trigger for allergies.

• Tip: Schedule annual HVAC maintenance to have coils cleaned and drain lines flushed.
   

• Why it matters: Prevents mold growth and keeps your indoor air clean.
   

4. Control Humidity Levels

High humidity creates a breeding ground for mold and dust mites, while low humidity can irritate your sinuses. Your HVAC system plays a big role in balancing humidity.

• Tip: Ask about dehumidifiers or humidifiers that can integrate with your HVAC system.
   

• Why it matters: Balanced humidity makes your home less hospitable to allergens.
   

5. Schedule Professional Tune-Ups

Preventative maintenance ensures your HVAC system is running efficiently and cleanly. Mohr AC’s technicians inspect and service components that directly impact air quality, from filters and coils to ductwork and blower motors.

• Tip: Have a professional HVAC tune-up at least once a year—ideally in spring before peak allergy season.
   

• Why it matters: Regular service helps catch problems early and keeps allergens from building up.
