When air quality is off in a building, it shows up in how the space runs. You start getting complaints, certain areas feel off, or systems are working harder than they should. Most of the time, it ties back to airflow, filtration, or moisture control.

Dunco provides commercial indoor air quality services for business owners, property managers, and facility teams across Topeka, Lawrence, and Gardner. Our goal is to improve comfort, reduce complaints, and keep systems running without disruption.

IAQ Solutions Designed for Busy Commercial Spaces

Our approach focuses on practical improvements that fit your building, your schedule, and how the space is used day to day.

Commercial IAQ Problems We Help Solve

Air quality issues show up as patterns across a building. These are some of the most common problems we address.

Odors, VOCs, and Lingering Smoke Smell

Persistent odors or chemical smells often point to poor ventilation or buildup of VOCs inside the space.

Mold and Moisture Concerns

Excess moisture can lead to mold or mildew, especially in areas with inconsistent humidity control.

Dust Buildup and Allergen Concerns

Dust collecting on surfaces or circulating through the air can affect both comfort and indoor cleanliness.

Ventilation, Fresh Air Intake, and CO2 Levels

Poor airflow and limited fresh air intake can cause spaces to feel heavy or uncomfortable, especially in high-occupancy areas.

Our Commercial Indoor Air Quality Solutions

We offer a range of solutions that target specific issues while improving overall building performance.

Indoor Air Quality Assessment and Recommendations

An indoor air quality assessment looks at airflow, filtration, humidity, and ventilation. From there, we provide clear recommendations based on how your building operates.

For system-wide improvements, our commercial HVAC services support how air moves through the building and how equipment performs.

Air Filtration Upgrades

Upgrading filters improves how air is cleaned as it moves through the system. We help determine the right balance between airflow and filtration using MERV ratings or HEPA filtration where appropriate.

Air Scrubbers and UV Air Purification

Air scrubbers and UV air purification systems help reduce airborne contaminants, odors, and biological growth inside the system.

Ventilation Improvements and Fresh Air Intake

Improving ventilation helps bring in outside air and reduce buildup inside the building. This is especially important in spaces with high occupancy or limited airflow, and commercial ventilation services can help address those issues.

Humidity Control

Humidity control includes both dehumidification and humidification depending on the season. Proper moisture levels help reduce mold risk and improve comfort.

Ongoing support through commercial maintenance services helps keep these systems working as intended over time.

Duct System Support for Commercial Buildings

The duct system plays a major role in how air moves through the building. When ducts are dirty or restricted, airflow and air quality both suffer, which is why commercial air duct cleaning may be recommended in some buildings.

Signs Your Duct System Needs Attention

If you notice uneven airflow, dust buildup, or lingering odors, the duct system may need cleaning or inspection.

In some cases, services like residential air duct cleaning provide a good reference point for how buildup affects airflow, even though commercial systems are larger and more complex.

Duct cleaning is not a fix for every issue, but it can improve airflow and reduce contaminants when buildup is present.

Filtration, Ventilation, and Humidity Control

These three factors have the biggest impact on indoor air quality.

Choosing the Right Filtration Level

Filters need to match the system and the building’s needs. Higher MERV ratings capture smaller particles but must be balanced with proper airflow.

Managing Humidity Throughout the Year

Humidity levels shift with the seasons. Proper control helps prevent moisture issues in the summer and dry air in the winter.

System performance also ties into commercial cooling and commercial heating, which both affect airflow and moisture levels.
