Your building
breathes through us.
We thread ductwork through drop ceilings and bring dead air back to life — in mid-rises, Class A towers, and aging office parks nobody else wants to touch.
Twelve tenant complaints in one July. A rooftop unit pulling 40% above rated amperage.
The building engineer at Lakeshore Centre had been fighting hot corners on floors 8 through 11 for two summers. Tenants on the south exposure were filing complaints weekly. The property manager was fielding calls every Monday morning.
Airflow Diagnostic — Pre-Install
The Finding
Behind the return plenum on floor 10, our crew found a 14-foot section of flex duct that had collapsed completely — twisted back on itself, sealed shut. It had been that way for at least two seasons. The supply air was backing up into the trunk and starving every zone south of the shaft.
The Install
Floors 9–11 opened, existing flex documented
14 ft of failed flex extracted, trunk inspected
Rigid galvanized duct fabricated on-site
All four zones balanced to design CFM
Energy Cost Reduction · Post-Install
RTU amperage dropped from 62A to 38A within 48 hours of commissioning. Zero tenant complaints in the following six months.
A 22-year-old rooftop unit bleeding $8,400 a month in excess energy.
The facility director at Meridian Tower had watched the utility bill climb for three consecutive years. The original 20-ton RTU on the east mechanical penthouse had never been replaced — just patched. The building was losing conditioned air through disconnected duct joints across floors 4 through 7.
When the GC brought us in, the unit was running at 58% efficiency and two compressors were cycling on high-pressure fault every afternoon.
Pre-Install Conditions
Scope of Work
The GC needed a mechanical sub who'd show up Tuesday. And finish Friday.
A general contractor on a Class B office renovation at 500 Woodward had their original mechanical sub pull out three weeks before the HVAC rough-in window. Five floors of new ductwork needed to be designed, fabricated, and installed in four days. They called us at 5 p.m. on a Monday.
The Schedule
"We've worked with a dozen mechanical subs over the years. Duct is the only one we've never had to call twice about the same problem."
Sheet metal work, start to finish. No handoffs, no excuses.
Ductwork Fabrication & Installation
Sheet metal fabricated on-site or in our shop. Round, rectangular, and oval. Galvanized, stainless, or lined. We thread it through whatever the architect drew.
RTU Replacement
Rooftop unit changeouts from 5 to 60 tons. Crane coordination, curb adaptation, controls integration. One crew, one invoice.
VAV System Commissioning
Variable air volume box installation, wiring, and DDC integration. Test and balance performed in-house or coordinated with a third-party T&B firm.
Retrofit & Renovation
Occupied building retrofits are our specialty. We work nights and weekends. Ceiling grid comes down clean and goes back up clean.
Diagnostic & Airflow Testing
Thermal imaging, duct leakage testing, airflow measurement. We find what's wrong before we recommend what to replace.
Mechanical Subcontracting
For GCs who need a sub that shows up on schedule and doesn't create RFIs. We read drawings, we build what's on them, we call you when there's a problem.
