> Post-renovation HVAC cleaning removes construction dust from ductwork and improves airflow efficiency.

## Key points

- Post-renovation duct cleaning improves indoor air quality.
- Cleaning ducts prevents the spread of dust and contaminants.
- Efficient HVAC systems require clean ducts to function optimally.

A major renovation may transform how a building looks, but preparing a facility for occupants also means addressing the systems operating behind the scenes.

## The need for HVAC cleaning after renovation

In this BMS CAT Project Profile, Colin Trudo, Director of HVAC Services at BMS CAT, takes viewers inside a university dormitory project in Dallas, Texas. The facility recently underwent a complete remodel that included the installation of a new air handler. However, the existing ductwork remained in place, creating the need for a comprehensive HVAC system cleaning before students returned.

BMS CAT was brought in to clean the ductwork, VAVs, and registers throughout the dorm. The goal is to remove construction dust and other contaminants that may have accumulated within the system while helping support indoor air quality and airflow.

> The project presents several challenges. Tight spaces, small ductwork, and numerous turning vanes require crews to create additional access points to thoroughly clean the system. — Colin Trudo, Director of HVAC Services at BMS CAT

The team is also working against a three-week deadline before students move back into the facility.

## Benefits of thorough duct cleaning

For Trudo, success goes beyond completing the cleaning on time. Before-and-after documentation helps verify that the work was completed properly, while crews ensure the facility is left clean and ready for occupancy.

> A thorough duct cleaning can also provide benefits beyond removing contaminants. Clearing buildup and obstructions can improve airflow through the system, helping HVAC equipment operate more efficiently.

The end goal is simple: a clean, documented HVAC system and a newly renovated dorm ready to welcome students back to campus.
