If you live in North Alabama, you already know how intense allergy season can be. From the yellow film of pollen that coats everything in spring to lingering allergens during the summer and fall, keeping your home comfortable and your air clean can feel like a losing battle. The good news? Your HVAC system can do more than just keep you cool or warm — it can be your first line of defense against allergy triggers in your home.

Here’s your pollen survival guide to help you breathe easier this allergy season.

1. Upgrade to High-Quality Air Filters

Not all air filters are created equal. Standard filters trap large particles like dust but let much of the pollen and smaller allergens pass right through.

Look for MERV 11 or higher filters designed to capture microscopic particles, including pollen, mold spores, and pet dander. Clifford’s HVAC recommends replacing filters every 30–60 days during peak pollen season — more often if you have pets or allergy-sensitive family members.

Pro Tip: Ask about HEPA filter options for even greater filtration without sacrificing airflow.

2. Schedule a Professional Duct Cleaning

Pollen doesn’t just float in your home — it settles in your ductwork, where it can recirculate every time your system runs. A professional duct cleaning removes that buildup, improving air quality and helping your system run more efficiently.

Regular cleaning every 3–5 years can make a big difference, especially for households with severe allergy sufferers.

3. Add an Air Purification System

Whole-home air purifiers work alongside your HVAC system to eliminate allergens, bacteria, and even odors from your indoor air.

Popular options include:

• UV light systems to neutralize bacteria and mold

• Electronic air cleaners to capture fine particles, including pollen

• Probiotic air systems for a natural, chemical-free way to improve air quality

These systems are low-maintenance and can be installed without major changes to your existing setup.

4. Control Humidity Levels

Pollen and allergens love high humidity. Keeping indoor humidity between 40% and 50% can help reduce allergen buildup and make your home feel more comfortable.

A whole-home dehumidifier or properly sized HVAC system can help you maintain consistent humidity levels year-round.

5. Schedule Seasonal Maintenance

Your HVAC system needs to be in top shape to filter and circulate clean air efficiently. A spring tune-up ensures your system is clean, calibrated, and ready to handle the added demands of allergy season.

During maintenance, Clifford’s HVAC techs will:

• Inspect and clean coils and drain lines

• Check for airflow issues

• Ensure your system is properly sealed

• Recommend filter and accessory upgrades

6. Create an Allergy-Free Home Routine

Even the best HVAC system works better when combined with good habits:

• Keep windows closed during peak pollen hours

• Vacuum frequently with a HEPA filter vacuum

• Change clothes and shower after spending time outside

• Wipe down pets when they come indoors to reduce pollen transfer
