Commercial Duct Cleaning for a Richardson Office

A 9,000 square foot multi-tenant office in Richardson’s Telecom Corridor with three rooftop units and widespread air-quality complaints. We cleaned the entire system overnight so the tenants never lost a working hour.

How the job went

Every project, the same way: look, show, fix, prove.

01

The call

Tenants had filed maintenance requests over dust settling on desks, dark smudges around the ceiling diffusers, and stale air. Building analytics also showed the three rooftop units drawing noticeably more electricity than the same period in prior years, a sign of heavy restriction in the ducts.

02

What the camera found

Commercial systems use large square trunks, acoustic liners, turning vanes, and built-in fire dampers, which create dead-air pockets where office dust and paper particulate settle and choke airflow. That buildup was restricting all three rooftop units and coating the coils.

03

The work

To keep the working tenants undisturbed, our commercial crew ran a night-shift operation starting Friday evening. We split the floor plate into six zones and connected trailer-mounted industrial vacuums to the rooftop return plenums to pull heavy negative pressure through the trunks. Long-reach air whips and reverse-jet tools traveled the main runs to drive years of dust and carbon off the metal and turning vanes into our containment collectors. Every supply diffuser and return grille was removed, washed, sanitized, and reinstalled to spec.

04

The result

Static pressure across all three rooftop units returned to baseline, restoring proper airflow to the suites, and cleaner coils and ducts brought peak cooling energy draw back down. The entire job finished overnight, and the offices opened on time Monday morning with no disruption.

Questions about this job

What homeowners ask when they see a project like this one , answered straight.

Can you clean our offices without disrupting the workday?

Yes. We schedule commercial work after hours and overnight, so the ducts are cleaned and the suites are ready to open on time the next morning.

Heavy buildup in the trunks and on the coils restricts airflow, so the rooftop units work harder and draw more power. Cleaning them brings that back down.

That is fine dust being pushed out of dirty ducts and settling around the diffusers. Cleaning the system and washing the diffusers clears it.

We split the floor into zones and work through them with trailer-mounted vacuums on the rooftop returns, so the whole system is cleaned methodically in one operation.

Yes. Every supply diffuser and return grille is removed, washed, sanitized, and reinstalled as part of the job.
