Commercial HVAC Systems – What We Can Service

Our team has working experience working in commercial buildings. All equipment, such as rooftop units, boilers, chillers, pumps, cooling towers, make-up air systems, exhaust fans, controls, heat pumps, and hydronic distribution systems, interacts with one another.

When one component is not performing correctly, the symptom may appear somewhere else. A failed heat pump may actually be experiencing poor loop flow.

A building struggling to cool may have an RTU issue, a dirty condenser, a control problem, a failed pump, a cooling tower deficiency, or an incorrect system operating condition.

An overheated mechanical room may be related to exhaust, ventilation, controls or failed equipment.

That is why Home Trade Standards focuses on diagnosing the system before recommending the repair.

Our objective is not simply to replace a failed part.

Our objective is to determine:

What failed? Why did it fail? What else should be checked? And what should the building do next?

Commercial HVAC Repair Services – Common Problems

When commercial HVAC equipment fails, getting the correct diagnosis matters.

Our technicians investigate heating, cooling, refrigeration, airflow, water flow, controls and mechanical operation to determine the cause of a problem before recommending repairs.

Commercial HVAC troubleshooting may include:

Compressor and refrigeration diagnostics
Refrigerant leak investigation
Electrical troubleshooting
Motors and contactors
Capacitors and relays
Control boards and sensors
Low- and high-pressure faults

Commercial Heat Pumps & Fan Coil Systems

One of Home Trade Standards’ key strengths is our experience with multi-residential and high-rise HVAC systems.

We work with buildings containing large numbers of:

Vertical & Horizontal Water-source heat pumps
Ceiling Fan coil units
Vertical stack heat pumps
Packaged terminal units
In-suite HVAC equipment
Common-area HVAC equipment

This gives our technicians an important advantage when a problem appears to affect both individual equipment and the building’s central mechanical system.

Instead of treating every failed unit as an isolated problem, HTS can investigate factors such as:

Building loop temperature
Water flow
Isolation valves
Strainers
Pumps
Cooling towers
Boilers
Risers
Controls
Equipment condition

For condominium and multi-residential buildings, this suite-to-mechanical-room understanding can be particularly valuable.

When ventilation equipment is inaccessible or building construction must be modified to reach it, we can identify the requirement so management can coordinate the appropriate trade.

Commercial HVAC Replacements & Retrofits

Eventually, repairing older HVAC equipment stops making financial or operational sense.

HTS can help building owners and property managers evaluate whether equipment should be:

Repaired → Rebuilt → Retrofitted → Replaced

We can assist with:

Existing-equipment assessment
Nameplate and model verification
Replacement equipment selection
Equipment sourcing
Retrofit planning
Removal and disposal
