Who Do We Serve?

Since 1976, United Mechanical has been a trusted mainstay in Oklahoma’s HVAC industry. We work with our customers to develop complete heating, cooling, or ventilation system solutions for a wide range of commercial projects. Our team of expert technicians provides top-shelf service, working closely with our customers from start to finish to ensure satisfaction.

With this dedicated customer service, we meet the HVAC needs of a wide range of businesses and industries who face distinct challenges presented by their industry as well as our ever-changing Oklahoma climate.


Maintaining a comfortable environment within your bank is critical to keeping employees and customers happy. Temperature and humidity control needs vary across server rooms, vaults, the safety deposit box room, and lobbies. HVAC systems can become fairly complex. Work with our team of experts to develop a system that addresses each of these needs.

Data Centers

Temperature, humidity and dust are critical considerations for data center HVAC systems. To keep systems from crashing due to high heat or cold, it's critical to find an HVAC company you can trust. Our team provides the experience and expertise to keep your systems online and functioning properly.

Hospitals & Medical Facilities

HVAC systems for medical facilities present unique challenges. In addition to climate control, they must take into consideration the presence of airborne contaminants, infection-spreading organisms and odors. Our HVAC technicians and designers are experienced working within these stringent requirements and can work with you to design a system that meets your facility’s needs.

Industrial & Warehouse Facilities

HVAC systems for industrial spaces such as factories, distribution centers and warehouses can be challenging with their massive open work and storage areas. We are proud of our proven track record tailoring commercial HVAC services and solutions to numerous industrial facilities. We can customize a solution and services to fit your industrial buildings’ needs.


According to the EPA, HVAC systems are among the largest energy consumers in schools. The choice and design of the system can also impact many aspects such as air quality, occupant comfort, and acoustics. Our experienced HVAC team can design a cost effective, energy efficient system to ensure students, teachers and staff enjoy a safe and comfortable learning environment.


A central heating and ventilation system is a must for most office work environments. By keeping your building's HVAC in balance with workers' needs, we help maintain a healthy bottom line for you.

Uncomfortable employees and customers can cost your business. A well-maintained central heating and ventilation system will help you keep everyone comfortable while maximizing efficiency, lowering operating costs, and keeping business moving. Our expert technicians can help you meet your HVAC goals.

Houses of Worship

Maintaining a comfortable temperature during worship will help keep your congregation happy and focused. HVAC systems need to be quiet and unobtrusive as possible to not disturb your members. They also need to be efficient to help ease the financial burden on the budget. Our experts can help customize a system that meets all of your house of worship’s needs.

Climate-Controlled Facilities

For a more consistent indoor environment, consider a climate control system. Zoned heating and cooling, automation, and remote operations are just some of the technology that allows you to control your HVAC system. Our technicians can work with you to develop a system to optimize your environment and reduce energy consumption.
