Spring Allergies Are Getting Worse — Here’s How to Improve Your Indoor Air Quality

Allergy Season in Central Ohio

If your allergies feel worse every spring, you’re not imagining it, especially here in Columbus.

A new report from Climate Central found that allergy season is getting longer across nearly 90% of U.S. cities. In Columbus, the growing season — the time between the last spring freeze and first fall freeze — has expanded by nearly a full month since 1970.

That means more pollen, earlier blooms, and longer exposure to the allergens that trigger sneezing, congestion and itchy eyes.

And while many people think of allergies as just an outdoor problem, the reality is that your indoor air quality can play a major role in how you feel day to day.

Why Spring Allergies Can Feel Worse Indoors

It might seem counterintuitive, but your home can actually trap and circulate allergens. As pollen levels rise outside, particles make their way indoors through:

• Open doors and windows
• Shoes, clothing and pets
• HVAC systems that aren’t properly maintained

Once inside, these allergens can continue circulating through your home, especially if your system isn’t filtering air effectively.

Signs Your Indoor Air Quality May Be Poor

Not sure if your home’s air quality is part of the problem? Here are a few common signs:

• Dust builds up quickly around vents and surfaces
• Allergy symptoms feel worse at home than outside
• Your home feels stuffy, dry or overly humid
• You notice lingering odors or poor airflow

If any of these sound familiar, your HVAC system may not be doing enough to support clean, healthy air.

5 Ways to Improve Indoor Air Quality This Spring

The good news: there are simple, effective ways to reduce allergens and improve your air at home.

1. Change Your HVAC Filters Regularly

Your air filter is your first line of defense against pollen, dust and other airborne particles. During allergy season, it’s best to check and replace filters more frequently — typically every 1–3 months.

2. Upgrade to High-Quality Air Filters

With options ranging from standard filters to HEPA and high-MERV systems, choosing a higher-efficiency filter can help capture smaller particles and significantly reduce indoor allergens.

3. Install a Whole-Home Air Purifier

Whole-home purification systems work with your HVAC system to remove airborne contaminants throughout your entire house — not just in one room.

4. Control Your Home’s Humidity

Humidity plays a big role in air quality. Too much moisture can lead to mold growth, while air that’s too dry can irritate your respiratory system. A whole-home humidifier or dehumidifier helps maintain the right balance.

5. Schedule Duct Cleaning

Over time, dust, pollen and debris can build up in your ductwork and continuously circulate through your home — especially if there are leaks pulling in additional allergens from attics, basements or crawl spaces.

If you’ve ever wondered whether duct cleaning is necessary, what the process looks like or what’s actually circulating through your home, this quick breakdown walks through what to look for and what to expect.

Professional duct cleaning and sealing your ductwork can help remove these hidden pollutants and keep the air you breathe cleaner and more controlled.

For many homeowners, the difference is noticeable right away. As one customer shared,

“Excellent duct cleaning service. Our tech was hard-working, professional and polite. What a great human being as well!!!” — Mark T

Taking the Next Step Toward Cleaner Air

If you’ve already swapped your filters and made a few changes but aren’t noticing a difference, it may be a sign that something deeper is impacting your home’s air quality.

In many cases, issues such as poor airflow, hidden duct buildup, or inconsistent humidity levels require a more comprehensive look at your HVAC system. That’s where a professional assessment can help identify what’s actually contributing to allergens in your home and recommend solutions that go beyond quick fixes.
