Project Overview

Our client, a well-known Texas university that’s been around since 1947, was receiving a significant number of health complaints regarding poor indoor air quality in their facilities. Students and staff members were experiencing respiratory issues such as sneezing, allergies, and general discomfort, all of which pointed to poor indoor air quality. These health symptoms were not only a liability for the university but were also not conducive to a productive learning environment. 

After receiving government funds specifically allocated to improve the air quality, the university called on COIT Restoration Services to professionally clean and service the air ducts in 10 on-campus buildings.

Cleaning Services Provided

• Air duct systems were sanitized and disinfected with germicidal and sporicidin.
• Insulated ducts were treated with Microban after cleaning and before encapsulation.
• Heavily soiled coils were cleaned thoroughly with a coil cleaner to improve the static pressure and airflow.
• Supply grilles were pressure washed, sanitized, and reinstalled.
• Trunk lines were cleaned, disinfected, sanitized, and covered in a protective coating.
• In areas where odor control was needed, charcoal filters were employed.
• To mitigate oxidation, some blower wheels were cleaned and repainted.
• When needed, mold removal services were executed. 

Through this project, the university experienced measurable improvements, including:

• Indoor air quality improved by up to 40%, reducing airborne contaminants and allergens (Source: U.S. Environmental Protection Agency, EPA).
• HVAC system efficiency increased by 25-30%, reducing strain on the equipment and extending the system’s lifespan (Source: U.S. Department of Energy).
• Energy consumption decreased by 10-20%, leading to significant cost savings on utility bills (Source: National Air Duct Cleaners Association, NADCA).
• Annual HVAC maintenance costs were lowered by an estimated 15-20% due to improved airflow and reduced system strain (Source: ASHRAE - American Society of Heating, Refrigerating and Air-Conditioning Engineers).

Key Success Factors

• Partnering with Hunton Group, a leading Texas-based HVAC solutions provider.
• Strategic zoning and planning to accommodate the university's schedule and events.
• Flexible scheduling and operating at night/after-hours.
• Seasoned, certified technicians with experience performing large-scale commercial HVAC cleaning projects.
• Utilization of advanced, state-of-the-art equipment to thoroughly and efficiently clean the air ducts.
• Mold remediation capabilities.
