Celtic’s staff of 200+ manufacturing and construction professionals along with our support staff ensure that our work is completed to the highest possible standard. Departments within our company include Engineering, Estimating, Field Operations, Manufacturing, Transportation and Finance & Administration.


At Celtic, we realize that our people are the most valuable asset we bring to a project. Each member of our team brings a different skill set, perspective, and personality that enhances both project success and workplace atmosphere. Together, our departments work closely with our clients, design partners, and trade contractors to design, develop and deliver comprehensive solutions.


Celtic’s engineers and draftsmen (aka sketchers) use state of the art tools to design the HVAC solutions that the company manufacturers and installs. Located in the company’s Orangeburg, NY office, our engineering team works closely with the other departments at Celtic, particularly manufacturing and field project management, to ensure our finished product not only meets but exceeds customer expectations.


Software applications used by our engineers include Building Information Modeling (BIM), an intelligent 3D model-based platform that provides the tools to efficiently design, manufacture, and install our product. Our engineers and sketchers are also proficient in the use of Navisworks, and Autodesk’s AutoCAD  and Revit applications.

Estimating cost is a critical step in the bidding process and one that also plays a major role in ensuring the successful implementation and completion of any project.


At Celtic our estimators collect and analyze all the data available for any given project in order to determine the time, materials, and labor required to manufacture and install our product. The information gathering process typically involves examining project blueprints to determine  functionality requirements, as well as performing material take-offs to determine quantities needed.  Our estimators then work closely with Celtic senior management, as well as manufacturing and field personnel to ensure project estimates are as accurate as possible.

Field Operations

With a job site workforce of as many as 200 personnel at any given time,  “on the ground” leadership is critical to the success of our projects. Our job foremen provide this leadership and ensure that our projects stay on schedule and on budget. We are proud to acknowledge that our job foremen have an average of over 15 years of service with the company.


Celtic’s front line sheet metal workers install our product on the job site.  These highly trained workers bring a level of professionalism and skill that is second to none in our industry. All field staff are, at minimum, OSHA 30-hour certified for construction safety.


Our job foremen and sheet metal workers are all proud union members. Celtic is a signatory contractor with the Sheet Metal Workers Local Union #28, the Sheet Metal Workers Local Union #38, the Teamsters Local #282, and the Teamsters Local #456.

Opened in 2017, our 124,000 square foot production facility located in Orangeburg, NY is comprised of separate fabrication and manufacturing shops.


In our fabrication shop, sheet metal workers and other production personnel use state of the art equipment including highly automated plasma cutters and punch press machines to produce HVAC duct work and a variety of other air-side HVAC products. Our specialized design software is fully integrated with our shop floor production equipment which allows us to quickly design and fabricate product for jobs of any size.


Once fabricated, finished product is shipped to our jobs sites in the Greater New York City area.


In our manufacturing shop, sheet metal workers make a wide range of air control products for resale. It is important to keep air flowing efficiently, quietly and safely in buildings where people work and live. That’s why we offer the best air control solutions in the industry. From dampers and louvers, to air measuring systems we deliver consistent innovation, engineering excellence and precision manufacturing.

State-of-the-art Production Technology

Using advanced production technology ensures we can efficiently and effectively service the needs of even the most complex projects. Suppliers of the state-of-the-art plasma cutting, punch press, and material handling technology used in our Orangeburg, NY facility include Mazak, LVD, and Remmert.

Project Management

Celtic’s project managers have overall responsibility for controlling the cost and quality of the construction projects they oversee. They plan and coordinate all aspects of the construction process, working closely with contractors, engineers, architects, vendors and others to ensure the project is completed on time and on budget. A project manager will typically begin a project by determining the scheduling of different phases of a project based on deadlines established with the various stakeholders.


Celtic’s project managers may have responsibility for a single project or multiple projects at any one time. This typically depends on the size of the construction project(s) in question as well as the experience level of the project manager involved.


Once a project is underway project managers confer regularly with supervisors and other managers to monitor construction progress, productivity levels, and compliance with building and safety codes. All project managers attend a weekly project progress review meeting.

Transportation & Logistics

Logistics is a critical part of any project plan. Celtic’s transportation department ensures that product moves effectively and efficiently between plant and jobsite every time.


Flexibility in how and when we deliver product is one of our greatest strengths. We work closely with our customers to schedule deliveries to arrive onsite at a time that works for all parties involved. Our fleet can accommodate loads of many sizes and our highly trained drivers ensure that all loads are delivered safely and on time.

Finance and Administration

Celtic’s finance and administrative personnel are located in the company’s Orangeburg, NY headquarters.


The finance/administrative team’s responsibilities include accounting, payroll, contract management, change order management,  billing & accounts receivable,  purchase order and requisition management, and accounts payable.


The team works closely with each departments within the company as well as with other stakeholders to ensure that customers are billed accurately and that employees and contractors are paid on time.
