Tell Us About the Work Needed

Tell us what the equipment is, what is happening, where it is, and how to reach it. Include tenant hours, safety rules, roof access, parking, and any timing concerns that may affect the work.

Service and Repair

We respond to commercial HVAC, boiler, and chiller issues. This can include loss of cooling, loss of heat, leaks, alarms, noise, short cycling, weak airflow, or repeat trouble on the same unit.

Retrofit and Replacement

We check equipment size, curb fit, power, piping, controls interface, access, roof conditions, and the schedule before the project is planned. The goal is to make the work easier to understand before crews arrive.

Consulting

We help owners and facility teams think through equipment condition, service history, maintenance problems, budget concerns, and design questions. When the issue can be fixed, Zion Engineering can help with the repair work too.

Commercial Mechanical Services

We work on commercial systems that handle cooling, heating, ventilation, chilled water, boilers, and zone control in commercial buildings. The work may be a repair, a maintenance visit, a retrofit, an installation request, consulting, or field support for a construction project.

Commercial HVAC Service

HVAC service for rooftop units, split systems, air-side equipment, ventilation issues, comfort complaints, maintenance needs, and replacement planning. We check the unit, the space it serves, and the condition found in the field.

Mechanical System Service

Mechanical service for owners, facility managers, construction teams, and property teams that need help with equipment condition, valves, pumps, access problems, maintenance gaps, repair history, or replacement planning.

Commercial Chiller Service

Chiller service for commercial facilities with cooling loss, alarms, water-side issues, maintenance needs, repair planning, or replacement discussions. We look at the equipment and the building load it supports.

Commercial Boiler Service

Boiler service for heat complaints, seasonal maintenance, pump issues, piping concerns, pressure problems, and replacement planning. We check the boiler room and the systems tied to it.

Building Automation Systems

Building automation systems help commercial HVAC equipment follow schedules, hold setpoints, report alarms, and respond the way the building needs. We check the controller, sensor, alarm history, and equipment response, then make the appropriate repairs where needed.

VRF System Service

VRF service for buildings with zone complaints, indoor unit issues, outdoor unit alarms, uneven comfort, or retrofit planning. We check the layout, equipment response, and service access before narrowing the next step.

Rooftop Equipment Replacement

Rooftop replacement work depends on the planning that happens before the lift. We check equipment weight, dimensions, curb condition, rigging points, delivery timing, crane reach, landing area, roof protection, electrical service, piping, and service clearance.

Those details shape the construction schedule. They also help the facility team prepare for access, safety, tenant notices, traffic control, and any planned shutdown.

Street to Roof Coordination

A lift or equipment change touches more than the mechanical room or roof. We check staging space, truck access, crane path, pedestrian areas, roof protection, trade coordination, tie-in work, and turnover notes.
