At JB Mechanical, we do it all. From professional ductwork and piping services to custom-designed control, installation, and maintenance solutions, we offer the HVAC services you need to keep your building up and running.




At the core of any high-efficiency HVAC systems is a well-designed ductwork system. With our wealth of experience in ductwork projects ranging from simple package unit installations to the most complex and high tech-systems, we have the resources to streamline any HVAC ductwork project.

At JB Mechanical, we have the capability to plan, coordinate, and install HVAC sheet metal systems to suit your mechanical construction project’s specific needs utilizing all available duct materials, including galvanized sheet metal, stainless steel, aluminum, fiberglass, and black iron.

We also offer expertise in rectangular, round, and oval ductwork as well as custom shapes – like triangular ductwork – where it is required to meet the needs of particular projects. No matter the challenge, no duct job is too complex for JB Mechanical’s sheet metal crews.


From planning and engineering to installation and repairs, the experienced HVAC piping team at JB Mechanical provides expertise for any piping service project at any scale.

We recognize that HVAC piping is a key component of any well-designed HVAC system, and that finding the right piping for your specific needs is an important part of achieving the best performance for your overall HVAC system. That’s why we offer a vast range of materials, sizes, and piping systems, including welded, grooved, soldered, brazed, fused, and threaded piping systems in a selection sizes and alloys.

Simply choose your preferred delivery method, from design-build and plan-spec to design-assist and target value design, and our team of engineers will work with you to achieve top-quality designs for your specific project needs, on-time and within budget.

After design and installation, the team at JB provides assurance that your HVAC piping will continue to perform to exacting standards with maintenance and 24-hour emergency repair services for all of your mechanical piping needs.


Although we’ve built our reputation as the Pittsburgh tri-state area’s premier mechanical contractor, at JB Mechanical, we also offer the expertise to plan, coordinate, install, and manage your HVAC controls projects.
