Commercial Mechanical Construction

From ground-up builds to major renovations, we design, fabricate, and install the mechanical systems that make commercial buildings work. Fifty years of self-performed construction across Dallas-Fort Worth.

Mechanical Construction

Full-Scope Mechanical Systems for Commercial Projects

Mechanical construction is the heart of what Kahn Mechanical has done since 1974. While our service teams keep existing buildings running, our construction crews build the systems inside new towers, medical facilities, industrial plants, and major renovations across the Metroplex. This is large-scale work: central plants, whole-building air distribution, and the piping that ties it all together.

We deliver projects two ways. In design-build, we take responsibility for both engineering and construction under one contract, aligning budget and schedule early and giving you a single point of accountability. In plan-and-spec, we build to the design your engineer and architect provide, bidding competitively and executing to the drawings. Either way, we self-perform the mechanical work rather than passing it down a chain of subcontractors.

Our scope covers HVAC systems, central chiller and boiler plants, hydronic and process piping, sheet metal and ductwork, mechanical rooms, and tenant finish-outs, integrated with the building automation controls that run them. For single-system equipment replacement in an existing building, see our HVAC installation service.

Scope of Work

What We Build

A complete mechanical scope, engineered, fabricated, and installed by our own teams.

HVAC Systems
Air handling, rooftop units, VRF, and split systems designed and installed for new construction and additions.
Central Plants
Chiller and boiler plants for high-rises, campuses, and industrial facilities, built for reliability and efficiency.
Piping Systems
Hydronic, steam, process, and refrigerant piping fabricated and installed to specification and code.
Sheet Metal and Ductwork
Ductwork fabrication and installation that delivers balanced airflow across the whole building.
Mechanical Rooms
Equipment and pump rooms laid out for serviceability, safety, and clean coordination with other trades.
Tenant Finish-Outs
Mechanical build-outs and renovations that adapt existing space for new tenants and uses.
Delivery Methods

Design-Build vs Plan-and-Spec

Two ways to deliver a project, and we do both. Here is how they compare.

Our Process

How We Deliver a Project

A coordinated process from the first budget conversation to a commissioned system.

1
Preconstruction
We plan scope, budget, and schedule with your team, coordinating design, drawings, and constructability early.
2
Fabrication
We fabricate ductwork and piping to spec, so field crews install faster and cleaner with fewer surprises.
3
Installation
Our crews install and coordinate with other trades, keeping the project on schedule and to code.
4
Commission and Close
We test, balance, and commission the systems, then hand over documentation and warranties at closeout.

Common Questions

Mechanical Construction FAQ

What does a commercial mechanical contractor do?
A commercial mechanical contractor designs, fabricates, and installs the mechanical systems in commercial buildings, primarily HVAC, central plants, and piping, along with the ductwork and controls that make them work. On construction projects we handle that full scope, coordinating with the architect, engineer, and general contractor from preconstruction through commissioning.
Do you offer design-build, or only build to existing plans?
Both. In design-build we take responsibility for engineering and construction under one contract, which aligns budget and schedule early and gives you a single point of accountability. In plan-and-spec we build competitively to the design your engineer provides. We help you choose the delivery method that fits your project and timeline.
What size projects do you take on?
We handle large-scale commercial work, from central plants and whole-building systems in new construction to major renovations and tenant finish-outs. Our five decades of DFW projects range from corporate headquarters and high-rises to airports and public arenas. Share your project details and we will tell you honestly whether we are the right fit.
Do you self-perform the work or subcontract it?
We self-perform the mechanical scope with our own crews rather than passing it down a chain of subcontractors. That gives you accountability, quality control, and cleaner coordination on site. We fabricate ductwork and piping in-house, which speeds installation and reduces field surprises.
Can you handle mechanical for new construction and major renovations?
Yes. We build mechanical systems for ground-up construction, additions, and major renovations, and we integrate building automation controls as part of the work. For occupied buildings, we phase the work to keep operations running wherever possible.
How is mechanical construction different from HVAC installation?
Mechanical construction is project-scale work: full systems for new buildings, central plants, whole-building piping and ductwork, and major renovations, coordinated with the design and construction team. Our HVAC installation service is focused on replacing or installing individual equipment in an existing building. If you are replacing a rooftop unit or chiller, that is installation. If you are building or gutting a facility, that is mechanical construction.
