Alliance Mechanical Services: HVAC

Alliance Mechanical Services provides repair, replacement, new installation and engineering. This includes all HVAC equipment, from the simplest packaged rooftop units and make-up air ventilation systems to boilers, chillers, heat reclaim equipment and complex process piping.  We are dedicated to keeping up with current technology and furnishing our technicians with the best equipment and training available.

Alliance Mechanical Services is a member of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)



Alliance Mechanical Services: Controls

Alliance Mechanical Services has been servicing, installing, and upgrading control systems since our beginning in 1996. Our Building Systems Division has expertise in the design, programming, installation, and service of Johnson Controls Building Automation Systems for both new construction and retrofit projects. We have vast experience in executing a variety of projects including commercial office buildings, schools, clean rooms, data centers, commercial retail centers, and multiple-building campuses.

Our goal is to provide a control system that will reduce energy consumption but at the same time enhance occupant comfort utilizing a non-proprietary, open protocol, web-based, building automation system. A web-based system allows our service department the ability to review HVAC issues remotely, determine the nature of a problem, and potentially solve it without making a site visit.

Alliance Mechanical Services is uniquely qualified to help you manage, maintain, and service your existing control systems, ranging from pneumatic controls to DDC.

Call on us for advice on control system upgrades and replacements, as well as new system installation.


Air & Water Balancing

Alliance Mechanical Services: Air & Water Balancing

Alliance Mechanical Services is a certified member firm of the National Environmental Balancing Bureau (NEBB). We are NEBB certified in Air and Hydronic Balancing (TAB), Building System Commissioning (BSC), and Retro-Commissioning (RCx).

TAB - Testing, Adjusting, and Balancing is an essential part of any heating, ventilating, and air conditioning system installation. All HVAC systems require correct air and water flows to achieve optimum operating conditions, comfort levels, and energy efficiencies.

We are dedicated to keeping up with current technology and supplying our technicians with the latest instrumentation to furnish the most accurate and reliable measurements. Our technicians also have the ability to operate the latest direct digital controls (DDC) systems.

BSC - Building System Commissioning (new building commissioning) is a systematic process of ensuring that a building performs in accordance with the design intent, contract documents, and the owner's operational needs.

The process begins with our review of the design plans and specifications, review of the contractor's submittals and shop drawings, followed by site verification of the systems and equipment installation and start-up, functional and operational testing, and concludes with the training of the operational and maintenance staff.

Due to the sophistication of building designs and the complexity of building systems constructed today, we have found commissioning is necessary and beneficial to the building owner.

RCx - Retro-Commissioning (existing building commissioning) is a systematic process of evaluating, testing, adjusting, and correcting building systems to meet the current building requirements and improve comfort, and environmental quality, and optimize energy conservation.

Over time buildings undergo changes, whether from tenant improvements, changes in building use, or changes made to the mechanical or control system. By improving and sustaining your building's systems, you can expect reduced operational costs, higher occupant productivity, fewer "trouble calls," increased employee/tenant retention, and improved building performance.

Often, solutions can be implemented at low cost during the Retro-Commissioning process with little or no disruption to the building's operations.

With our knowledge, experience, and integrity, you can trust Alliance Mechanical Services to complete your project, no matter what the size or complexity, in a timely and professional manner.
