Keeping Your Facility Running Doesn’t Happen by Accident.
Unexpected shutdowns. Surprise equipment failures. Last-minute repair bills.
Every plant manager has lived that nightmare.
At DePue Mechanical, we’ve been on the rooftops, in the boiler rooms, and inside the process lines for 25+ years, and we know one thing: preventive maintenance (PM) isn’t just paperwork — it’s your facility’s insurance policy against chaos.
That’s why our PM Agreements are designed with boots-on-the-ground experience, not cookie-cutter checklists.
What’s Included in a DePue PM Agreement?
Every agreement is tailored to your facility, but here’s what you can count on:
Scheduled Service Visits
-
Weekly, monthly, or quarterly, performed by certified DePue technicians (not third-party subcontractors).
Critical Equipment Inspections
-
Boilers, chillers, pumps, piping, air systems, and controls — nothing skipped.
Filter Changes & Consumables
-
Air filters, belts, and fluid checks done on time, before they fail.
Documentation & Reporting
-
Maintenance logs, inspection reports, compliance photos — reports written for plant managers, not file cabinets.
Emergency Repair Priority
-
When things go sideways, you jump to the front of the line.
Why Choose Preventive Maintenance Instead of Waiting for Breakdowns?
We’ve seen it firsthand: a food manufacturer ignored their cooling tower until it failed on a Friday night. The downtime cost them $75,000 in lost production — in just one weekend.
With a DePue PM Agreement, you get:
-
Scheduled inspections that prevent failures
-
Extended equipment life
-
Predictable uptime
-
A dedicated team that already knows your systems
How the Process Works
We keep it simple, effective, and honest:
-
Site Walkthrough – We visit your facility, assess your systems, and document your critical equipment.
-
Custom PM Scope – A scope built for your plant’s frequency, budget, and compliance needs.
-
Agreement Signed – You approve the scope; we make it official.
-
Scheduled Services Begin – Our technicians show up on time, log every visit, flag future concerns, and report directly to you.
- No fluff. No hand-offs. Just predictable results.
Need a change? You can scale the scope up or down any time.
What Makes DePue Different?
We’re not just a service provider. We’re your mechanical contractor with steel-toe boots in the field.
-
We self-perform all work — no middlemen.
-
We know construction — we installed many of the systems we now maintain.
-
We show up — onsite, in uniform, and on time.
-
We know your equipment — because we’ve likely set it in place.
Other companies hand you a binder and disappear. We hand you a checklist and come back next month.

Proof in Action
“I operate a mid-sized commercial building in the Chicago burbs and changed my HVAC service to DePue Mechanical 4 years ago due to issues with my prior contractor. The DePue techs are outstanding. True professionals that know their trade. When I have an issue, DePue is quick to get me a service tech, and the job gets done right the first time. I would recommend DePue to anyone who has HVAC service or install needs. Finding a good, reputable contractor that actually provides the service claimed in the reviews can be challenging. Especially with so many options. But DePue hits the mark every time.”
— Aaron A, Maintenance Manager
“Have worked with DePue for 3 years and they have provided excellent service. Very good turn around for service work and good project management as well.”
— Quinn Hunt, Project Engineer
DePue is also a proud recipient of the TRMA Meritorious Award for operational excellence and safety — recognition earned by doing the work right, every time.
