Commercial HVAC Controls & Building Automation in Southeast Michigan

Your HVAC equipment is only as effective as the controls running it. Friedman Mechanical installs, programs, services, and upgrades commercial HVAC controls and building automation systems for facilities across Southeast Michigan.

Controls Are Where Efficiency is Won or Lost

A properly maintained rooftop unit running on a poorly calibrated control sequence will consume 20 to 30 percent more energy than the same unit running correctly. Setpoint drift, misconfigured scheduling, failed sensors, and outdated pneumatic controls are among the most common and least visible sources of energy waste and occupant complaints in commercial buildings.

Friedman Mechanical's technicians are experienced with the full range of commercial HVAC controls, from legacy pneumatic systems to modern digital controllers and full building automation platforms. We diagnose controls problems accurately, execute upgrades cleanly, and commission every system to perform as designed. Our goal is not just to make the controls work, but to make them work efficiently for your specific building and operational requirements.


What we do

Controls & Building Automation

Building automation system integration
System integration

Building Automation System (BAS) Integration

Full BAS integration for commercial HVAC systems including scheduling, setpoint management, zone control, alarm monitoring, and remote access. We work across most major BAS platforms and can integrate new or replacement equipment with existing infrastructure. For facilities without a BAS, we assess whether adding one is justified by the energy savings and operational visibility it provides.

Thermostat and zone sensor installation
Installation & calibration

Thermostat & Zone Sensor Installation

Commercial thermostat installation and zone sensor placement for single-zone and multi-zone HVAC systems. Proper sensor placement is frequently overlooked and is one of the most common causes of inaccurate zone temperature readings and comfort complaints. We locate sensors correctly and verify calibration after installation.

Economizer controls
Service & calibration

Economizer Controls

Economizer systems installed, serviced, and calibrated to take advantage of free cooling from outdoor air when conditions allow. A malfunctioning economizer is one of the most common sources of excessive cooling energy consumption in commercial buildings. We test economizer operation as part of every controls and maintenance visit.

Digital controls installation and programming
Installation & programming

Digital Controls Installation & Programming

Commercial digital control systems installed and programmed for HVAC applications including rooftop units, air handlers, VAV systems, boilers, chillers, and fan coil units. Control sequences are written and commissioned to match your facility's actual occupancy patterns and operational requirements, not generic defaults.

Controls diagnostics and repair
Diagnostics & repair

Controls Diagnostics & Repair

HVAC performance issues that appear mechanical are often controls problems. Friedman Mechanical technicians diagnose the full controls chain before assuming equipment failure. A failed sensor, a drifted setpoint, or a communication fault between controller and equipment can cause symptoms that look like mechanical failure and result in unnecessary parts replacement. We find the actual cause.

Remote monitoring and reporting
Monitoring & visibility

Remote Monitoring & Reporting

Controls configuration that provides facility managers and property owners with remote visibility into system performance, alarm conditions, and energy consumption. Useful for multi-building portfolios and facilities where on-site management resources are limited.

Pneumatic controls service and conversion
Service & conversion

Pneumatic Controls Service & Conversion

Many commercial buildings in Southeast Michigan still operate on pneumatic control systems installed decades ago. Friedman Mechanical services and repairs pneumatic controls, and also evaluates and executes conversions to digital systems where the efficiency and reliability improvements justify the investment. We understand both technologies and make the recommendation based on your building's specific situation.

Demand-controlled ventilation
Ventilation controls

Demand-Controlled Ventilation (DCV)

CO2-based demand-controlled ventilation systems installed and commissioned for commercial facilities looking to reduce ventilation energy costs while maintaining indoor air quality compliance. Particularly valuable for spaces with variable occupancy such as conference rooms, classrooms, and retail environments.

Controls upgrades for existing equipment
Upgrades & retrofits

Controls Upgrades for Existing Equipment

Older HVAC equipment with outdated controls can often be upgraded with modern digital controllers that improve efficiency and reliability without requiring full equipment replacement. Friedman Mechanical evaluates controls upgrade opportunities as part of every service visit and maintenance agreement.

Common Applications

Office Buildings & Multi-Tenant Properties | Medical & Dental Facilities | Manufacturing & Industrial Spaces | Retail Centers | Educational Facilities | Data Centers & Server Rooms | Buildings With Legacy Pneumatic Systems | Multi-Site Portfolios Requiring Remote Monitoring | Facilities With Energy Compliance Requirements

  • A building automation system is a centralized platform that monitors and controls HVAC equipment, lighting, and other building systems from a single interface. Whether a BAS is justified depends on your facility size, energy spend, and how much operational visibility you currently have. Friedman Mechanical can assess your situation and give you a straightforward answer on whether the investment makes sense for your building.


  • Pneumatic controls use compressed air to operate dampers and valves and were standard in commercial buildings prior to the 1990s. Digital controls use electronic signals and microprocessors to perform the same functions with greater precision, easier programming, and remote monitoring capability. Many older Michigan commercial buildings still operate on pneumatic systems. Friedman Mechanical services both and evaluates conversion opportunities based on the specific cost-benefit for your facility.

  • In most cases, yes. Modern commercial HVAC equipment supports standard communication protocols such as BACnet and Modbus that allow integration with most major BAS platforms. Friedman Mechanical handles controls integration as a standard part of every equipment installation.

  • The most common indicators are energy consumption that has increased without a change in occupancy or usage, equipment running during unoccupied hours, and spaces that consistently fail to reach setpoint. Friedman Mechanical includes controls diagnostics in every service call and can perform a dedicated controls audit if energy performance is a concern.

  • Yes. We install and commission CO2-based DCV systems and can advise on Michigan mechanical code and ASHRAE 62.1 ventilation requirements as they relate to your facility type and occupancy classification.
