Professional HVAC Cleaning for St. Louis Businesses

At Pro Tech Commercial Air Duct Cleaning of St. Louis, we provide specialized commercial and industrial HVAC cleaning services for office buildings, corporate campuses, and large-scale facilities. Our advanced cleaning equipment and antimicrobial treatments help ensure your HVAC systems operate efficiently, maintain compliance, and deliver clean, healthy air throughout your property.

Why Professional Duct Cleaning Matters for Commercial Properties

Large office and corporate HVAC systems circulate air continuously. Over time, contaminants like dust, debris, and microbial buildup restrict airflow, increase operating costs, and degrade air quality.
Pro Tech’s certified technicians restore your system’s performance with complete duct and component cleaning that supports energy efficiency and employee health.

Key Benefits:

  • Cleaner, healthier air for employees and visitors

  • Lower energy bills through improved HVAC efficiency

  • Extended equipment life and reduced maintenance costs

  • Compliance with OSHA, EPA, and ASHRAE air quality standards

  • Enhanced comfort and consistent airflow across the building

Operations Manager/Walmart
Your workmen were efficient and did an excellent job of cleaning up any debris left over from their work. The air condition system was left working very smoothly and the air in the sanctuary was noticeably cleaner.
Property Manager/Lynn Schuetz
Recently we had the pleasure to hire Pro Tech. We found their employees to be professional and efficient… They went above and beyond to protect kitchen equipment and left everything in a very clean condition. Most importantly, at all times, they were very considerate of the residents and their comfort.
