Custom Fabrication

Plumbing & HVAC Solutions Through Fabrication Design

Cooper Oates provides customized solutions for heating, ventilation, air conditioning systems, plumbing and hydronics.  Our expert craftsmen generate precision work, on time and on budget.  Our in-house capabilities mean your project is protected from subcontractor mistakes and delays.

 

Our Fabrication Capabilities Include:

  • Sheetmetal Fabrication Shop
  • Pipe Fabrication Shop
  • Complete Custom Skid Fabrication and Design

 

As Cooper Oates grew and took on more retrofits and special projects, we realized how beneficial it was to our customers to create our own fabrication department. Our 15,000 sq ft warehouse is the site of our in-house fabrication workshop.  A precision plasma cutter, a welding shop, and specialized pipe fitting equipment mean that we can produce our own duct, plumbing, and piping assemblies, as well as customized packaged skids.

Our fabrication capabilities mean that we can create solutions all the way from basic plumbing to complex mechanical systems that service an entire facility. Our in-house team of experienced craftsmen has tight control over the quality of each element.

Even more important to scheduling and ultimately the bottom line of a project, creating our own duct work, pipe assemblies and customized skids keeps us safe from subcontractor delays and surcharges. This can be especially important if modifications are needed once work is underway.

Custom Sheetmetal Fabrication

Cooper Oates provides custom sheet metal fabrication for heating, ventilation and air conditioning systems. Our extensive sheet metal fabrication shop and expert craftsmen generate custom and precise work on time – the first time– and within budget.

While smaller mechanical contractors must typically use sub-contractors to produce customized sheet metal products, our construction and installation teams get the quick turn-around needed to keep a project on schedule. No shopping around to find the best price. No back orders from another vendor. No delays for just the right part. Our shop regularly fabricates all gauges of sheet metal, per SMACNA standards, for medium/low pressure, lined, stainless steel, and black iron ductwork.

 

Our Sheetmetal Fabrication Applications:

  • Tenant Improvements
  • HVAC Retrofits
  • HVAC Protection Cages and Theft Deterrents
  • Data Centers and Clean Room Air Systems
  • Custom Ventilation and Exhaust Systems

Pipe Fabrication

As the mechanical projects Cooper Oates has undertaken have become larger and more complex, we have focused not only on building a solid and experienced team of pipe fitters but are at the same time procuring the first-class tools required to manage the type of projects that Cooper Oates specializes in. Recent acquisitions in our pipefitting division include the Miller Pipeworx, Hypertherm Powermax 85, and the Pandjiris Model 30-6AB Positioner.

Fabricating HVAC sheet metal

We have the in-house capability to design and create:

  • Custom pipe spools
  • Pipe grooving, welding, and threading
  • Structural pipe supports
  • Domestic water piping
  • Sanitary drain, waste, and vent piping
  • Storm and roof drainage piping
  • Medical gas and vacuum piping
  • Natural and LP fuel gas piping
  • Specialty piping
  • Hydronic system
  • Plumbing Assemblies

Customized Skids

Piping systems are integral to every HVAC and Plumbing installation. Creating customized skids means fabrication is done in-shop, indoors. This can translate into higher quality standards than in-field fabrication.  It also ensures that every part of your piping assembly is properly installed and safety-tested before it is shipped to your job site.  When our team of licensed plumbers customize your project’s piping assemblies, solutions become seamless.

 

Complete Custom Skids Assemblies, Including:

  • Compressed Air
  • Domestic Booster Pumps
  • Boiler (Steam-Domestic Water-Heating Hot Water)

We partner with you to ensure your project is completed on-time and on-budget, with the highest level of excellence. Contact us to learn more about how we can support your project.

Testimonials

"They Provided Customized Solutions Tailored to My Needs"

 

I recently had the pleasure of working with Cooper Oates HVAC for a complete cleaning and service of the heating and cooling system at the Chico VA, and I couldn't be more satisfied.

From their prompt arrival to the thorough service, their team demonstrated exceptional professionalism and expertise. They provided customized solutions tailored to my needs, explained everything clearly, and ensured I felt confident in the service provided. The skilled technicians respected my facility and left it spotless.

The quality of their work is outstanding, with my two industrial units—one 100-ton and one 125-ton HVAC system—performing flawlessly and significantly reducing my utility bills. Their follow-up and customer service were exceptional, showing their commitment to long-term satisfaction. I highly recommend Cooper Oates HVAC for their dedication to excellence and customer care, making them my go-to HVAC service provider.

"I Have Had Nothing Other Than Exceptional Success and Joy Working With Cooper Oates Company"

I have had nothing other than exceptional success and joy working with Cooper Oates company.

First off, they take photos of whatever they are communicating to be a problem. I'm not up on the roof with them, so rather than having to rely on their word alone, they are building my trust and confidence by taking images of any existing problem AND images after their repairs. This is exceptional.

They are fast, efficient, courteous, pleasant and considerate. Personal connection and relationship-based business is becoming more and more rare. It is such a relief to find caring human beings who pick up the phone and don't route you through endless wasteful phone trees when you call them.

Thank you so much....all of you at Cooper Oates Air and Plumbing Services! I am very blessed to have found you!

"Their Team Answered Our Call on a Busy Holiday Weekend"

We highly recommend Cooper Oates Air Conditioning for their outstanding service, expertise, and professional team members. COAC is one of our top go-to subcontractors that we use on nearly every construction project! They are reliable, honest, and timely. Just earlier this year, their team answered our call on a busy holiday weekend. COAC showed up to the site within 2 hours and resolved the issue right away.

This is the kind of routine thing that they do at COAC: They take care of their customers and business partners. We can't thank them enough!

"Solid, Timely and Knowledgeable Performance"

I’ve had the pleasure of working with many technicians from this company. I have had a solid, timely, and knowledgeable performance every single time. We have a ton of HVAC used in controls for critical environments.

10/10 would recommend, even over the manufacturers of the units, unless necessary for proprietary circumstances. I plan to use COAC for all HVAC and where possible environmental control diagnostics.

Thank you for taking a few minutes to talk to me yesterday while you were out to perform maintenance on the system. What a nice change from what we have dealt with for years. Since the new system has been properly adjusted by the COAC team, we have had very few complaints. This has made a piece of my job tons easier. So on behalf of the DHHS tenants, a very big THANK YOU for the new control system.

"Professional Work"

I want to thank Cooper Oates for the recent work performed at the Elder Creek facility. (Technicians) Mike and Andrew did an outstanding job taking care of the issues we had. They made sure all work was done in a professional manner and did a great job communicating to me the process and did a great job cleaning up debris.

From the preliminary findings in the VP offices, there is much improvement in the noise level and balance of air distribution now. Again thank you for a job well done!

"Precise HVAC Redesign"

I would like to thank you all for the successful completion of the HVAC redesign in the Bureau of Nursing recently. Recognizing and rectifying this complex issue portrays your dedication to customer satisfaction. The tenant is very happy with the operation of the system and is reporting excellent comfort levels.

The project progressed smoothly and precisely as scheduled. I received no complaints or concerns during the project. It went so well in fact that I did not visit the project once until it was completed. I have complete confidence in (your Foreman) Anthony Vallejos and had no inclination that his jobsite was anything but perfectly tended. The only job issue was that the access card which I issued that never worked correctly. Anthony was very adaptable and got the job done anyway.

Please accept the sincere appreciation from Consumer Affairs and the Bureau of Nursing.

"Detailed Service"
