Who We Work With



Regardless of the hospital type, airborne diseases pose a unique challenge when designing HVAC units. Our HVAC technicians and designers work directly with the building's manager to ensure that filtration, humidity, and temperature are the way you want them.



A controlled climate is an important factor for students and faculty to be successful. We proudly work with many public and private institutions, as well as colleges and universities to develop effective, reliable HVAC systems.


Data Centers

Server towers are dramatically impacted by air quality, temperature, and humidity. The slightest changes in any of these variables can significantly impact system function. A robust, properly maintained HVAC system is critical to success, and is one of our specialities.



A bank’s HVAC system must be versatile. It must take into account various climate and air quality requirements such as for safety deposit box rooms, vaults, server rooms, lobbies and office space. Our team of HVAC technicians can design a system to meet these various needs.

Medical Facilities

Medical facilities have unique needs. When designing HVAC systems, airborne diseases present a unique challenge for the drafting and engineering of these systems. We talk to building managers throughout the HVAC engineering process to make sure that filtration, humidity, and temperature levels are as desired.


Climate-Controlled Facilities

For any indoor location that has specialty temperature needs, HVAC technicians need a specialized understanding of how to heat and cool these places. United Mechanical's team will work directly with building and facility management to get you the solution you need. 



Office buildings require reliable heating, air conditioning, and ventilation systems to maintain a comfortable environment. We can help improve workers’ satisfaction as well as operating costs with our top-of-the-line HVAC systems and maintenance plans.



Whether it’s for large congregating groups in the auditorium, small gatherings in classrooms, or anything in between, houses of worship need a quiet, efficient, unobtrusive HVAC system. Our systems can be customized to meet your needs.


Manufacturing Industries

HVAC systems in industrial settings contend with factors such as intense heat, large open expanses, dust, external openings, the list goes on. We draw on our extensive experience in these settings when we work with you to develop an HVAC solution that meets your needs.
