🧰 PART 2 OF 2: What Does Commercial Duct Cleaning Actually Look Like?
What exactly goes into a commercial HVAC duct cleaning project?
A lot more than most people realize.
The photos and videos in this post provide a closer look at the process used during our recent duct cleaning project at the Erie Western PA Port Authority and Definiti Facilities.
From establishing negative pressure with our commercial vacuum collection equipment, to agitating dust and debris throughout the duct system, every step is designed to thoroughly clean the system—not simply move contaminants from one location to another.
Registers, grilles, and diffusers were removed and meticulously cleaned to eliminate years of accumulated dust, soot, and grime. Access openings were strategically created throughout the system to ensure proper cleaning of both supply and return ductwork. Following the cleaning process, the duct system was sanitized before being sealed, restored, and returned to operation.
The before-and-after photos tell part of the story. The videos showcase the equipment, techniques, and effort required to perform commercial duct cleaning the right way.
There are no shortcuts when it comes to quality workmanship. Just the right equipment, the right process, and a team committed to delivering exceptional results.
At J.J. Agnello Heating & Air Conditioning, we believe the difference is in the details. ✅👏
