Specialized HVAC Services
For work that can't wait for a shutdown, or a fault a standard service call won't find. Live-system repairs, metering and diagnostics beyond routine installation and maintenance.
Live-System Work & Advanced HVAC Diagnostics
Chilled Water Pipe Freezing
Freeze a temporary ice plug on each side of the work, so valves and pipe sections can be replaced without draining or shutting down the chilled water system.
Learn moreHot Tapping & Live Line Tie-Ins
New branch connections into live, pressurized pipework for expansions and fit-outs on running chilled water or process lines, with no system downtime.
Learn moreLive Leak Repair
Stop leaks on chilled water and plumbing pipes, valves, flanges and joints while the line stays pressurized and in service.
Learn moreTesting, Adjusting & Balancing
Air and water balancing when a system underperforms, to find whether the fault is airflow, hydronics or controls, and correct it.
Learn moreHVAC Energy Audit
Measure how chillers, VRF and duct systems really perform against design, and get a report with prioritized, costed corrective actions.
Learn moreBTU Meters & BMS Integration
BTU meter installation for chilled water, with control valves and BMS integration so cooling energy can be monitored, billed and controlled.
Learn moreNoise & Vibration Diagnostics
Find the root cause of noisy or vibrating fans, pumps and ducts, such as imbalance, bearing wear or resonance, and fix it rather than hide it.
Learn moreRefrigerant Leak Detection & Repair
Electronic detection and pressure testing to locate refrigerant leaks in split, ducted and VRF systems, then repair and correct recharging.
Learn moreLive-System Work Needs Different Judgment Than a New Install
A standard install crew sizes and fits new equipment. This work is different: diagnosing a fault on a system that's already running, under load, with tenants or production depending on it staying online, and intervening without creating a bigger problem than the one you started with.
That's why hot tapping, pipe freezing and live leak repair sit apart from our regular install scope: they call for engineers who can read a system's actual behavior, not just its as-built drawing.
Typical Callers
- Facilities management engineers diagnosing a recurring fault
- Building owners who can't schedule a full system shutdown
- Buildings adding BTU metering and BMS monitoring
- Consultants requesting an independent energy audit
- Contractors needing a live tie-in on an occupied building
