Remote jobs

HVAC controls technicians install, program, troubleshoot, and maintain the control systems that govern how commercial HVAC equipment operates: thermostats, DDC controllers, actuators, sensors, variable frequency drives, and the sequences of operation that tie them together. The role overlaps with building automation but tends to be more focused on the field installation and wiring side of controls work, rather than high-level BAS programming. Controls techs work for controls contractors, mechanical contractors with in-house controls divisions, and facility teams managing complex commercial buildings. It is a specialty that rewards technicians who are both hands-on mechanical and comfortable with wiring diagrams, control panels, and basic programming logic.

Quick Facts

Role Type: Field technical; installation, wiring, startup, and troubleshooting Typical Salary Range: $65,000 - $112,000/year Hourly Range: $31 - $54/hr depending on specialization and platform depth Experience Required: 3-6 years HVAC or controls; low-voltage wiring and DDC programming experience required Job Outlook: Strong; controls scope is expanding on virtually every commercial mechanical project Common Employers: Johnson Controls, Siemens Building Technologies, Honeywell Building Solutions, Automated Logic, independent controls contractors, large mechanical contractors with controls divisions

Why Demand Is Strong

The commercial building sector's push toward energy efficiency, smart building integration, and real-time performance monitoring has expanded the controls scope on new construction and retrofit projects significantly. Where a rooftop unit previously might have had a basic thermostat, the same unit today is likely integrated into a DDC system with occupancy scheduling, demand-controlled ventilation, and energy data reporting. Retro-commissioning of existing buildings, a growing market driven by energy benchmarking laws in major cities, requires controls techs who can evaluate and reprogram existing sequences of operation. The integration of HVAC controls with IT infrastructure (BACnet/IP, cloud-based analytics platforms) is also creating demand for techs who understand both the mechanical side and the network side of a control system.

What Employers Are Looking For

Low-voltage wiring proficiency and the ability to read electrical schematics are foundational. DDC programming experience on at least one major platform (Niagara/Tridium, Metasys, WebCTRL, EcoStruxure) is required for most roles. BACnet protocol knowledge is standard; Modbus and LON familiarity is a plus. Tridium Niagara AX or N4 certification is the most commonly requested individual credential in controls technician postings. VFD startup and parameter configuration (Danfoss, ABB, Yaskawa) is increasingly expected. OSHA 10 is required for most construction-phase roles. Strong employers are also screening for the ability to write and modify sequences of operation, not just implement what someone else has written, which separates mid-level candidates from senior ones.
