Benefits of the United Mechanical Difference

Commercial HVAC Construction

If you have ever supervised the construction of commercial space, you know that something always seems to go wrong. That's why you want to hire someone with plenty of experience and skill, so you won’t have to worry about future issues.

Our construction division is experts in pre-planning and fabrication. We can reduce your operating costs from the beginning of your project, through careful energy-efficient design and best practices. 

You can count on United Mechanical Construction to optimize your building’s energy use, creating an efficient, smart building that will save money from the first day of operation.


Mechanical Construction Services

We offer full-service construction services, with attentive customer service and the most knowledgeable and experienced team in the area.

We perform all piping, ductwork fabrication, ductwork installation, plumbing, mechanical systems start-up, and mechanical systems warranty and maintenance with in-house personnel.

Our sheet metal, plumbing, and piping fabrication shops are located at our main office, which gives us the ability to perform extensive hydronic piping, sheet metal ductwork, and plumbing prefabrication assemblies to facilitate job site efficiency.

This also gives us the ability to maintain quality control and meet aggressive construction schedules.

As the largest employer of plumbing, pipefitting, and sheet metal tradespeople in Oklahoma, you can be assured we hire only the best technicians and experts. We have systems in place to ensure every deadline is met, and we will solve any problems before you have to worry.

Our construction division is the leader in “Building Information Modeling” technology in the Oklahoma market, a technology that has allowed us to minimize job site conflicts and maximize the use of prefabrication shops.

Our BIM department leverages the most current technology available and comprises competent personnel with a broad background in all facets of the design and construction process.

We are a community-oriented company, always looking for opportunities to work with local charities and causes. Our values of honesty, integrity, and doing the right thing are at the heart of everything we do.
