HVAC and Refrigeration

A system needs to be understood in its operating context. Controls, room use, air distribution and connected plant affect performance alongside the condition of individual components. The scope should explain both the equipment being worked on and the result needed at the site.

Air Conditioning — Cooling and comfort systems, from a reported fault to planned servicing and replacement.

VRV and VRF Systems — Multi-unit refrigerant systems with connected indoor units, controls and common outdoor plant.

Fan Coil Units — Local room units and their fans, coils, drainage and controls.

Air-Handling Units — Central air-handling equipment, its components and connections to the ventilation system.

Ventilation — Air supply and extract requirements shaped around occupancy, activities and existing systems.

Ductwork — Air-distribution routes, alterations and repairs coordinated with access and connected equipment.

Air and Ventilation Balancing — Measurement and adjustment of air distribution against the required system performance.

HVAC Maintenance and Servicing — Equipment-specific maintenance programmes, completion records and action on service findings.

Chillers and Cooling Towers — Cooling plant care, with evaporative cooling towers and their water controls treated separately.

Commercial Refrigeration — Refrigeration equipment investigations, servicing and repairs around operational requirements.

Cold Rooms — Cold-room equipment and enclosure issues, connecting temperature concerns with the whole installation.

F-Gas Compliance — Refrigerant-related requirements, equipment information, checks and records within the applicable regime.

TM44 Air-Conditioning Inspections — Air-conditioning energy inspections, distinguished from routine servicing and refrigerant leak checks.

Local Exhaust Ventilation (LEV) — Extraction systems that capture airborne contaminants close to their source.

LEV Examination and Testing — Examination and testing of extraction performance, with findings and remedial actions clearly recorded.

Kitchen Extract — Commercial kitchen extraction equipment and air paths, with access and operational needs coordinated.

Ventilation and Duct Cleaning — Cleaning of ventilation components and duct routes against a defined accessible scope.

Start with the symptom or intended change. Uneven room temperatures, weak airflow and a refrigeration alarm lead to different investigations. Include when the problem occurs, which areas are affected and what the system was doing at the time.

Servicing, cleaning, balancing and formal inspection also have different purposes. A service visit does not replace every specialist assessment. Identify the required outcome so the instruction produces the right work and records.

Use Fault Finding and Diagnostics for unclear faults and Planned Preventative Maintenance for scheduled care. Building Services Upgrades and Mechanical and Electrical Projects provide routes into larger changes.

For estate-wide work, retain the differences between sites. Similar-looking units can have different duties, controls and maintenance histories, so a common programme still needs accurate asset information.

Provide equipment schedules, previous reports, controls information and known faults. Agree access to roof plant, ceiling equipment and occupied rooms. Identify shutdown effects and the people who need notice before heating, cooling, ventilation or refrigeration is interrupted.

The delivery plan defines checks and completion evidence. Findings requiring another trade, a replacement part or additional investigation remain linked to the original job until the agreed outcome is complete.

Equipment type, fault complexity, refrigerant, access and required downtime affect scope and cost. Concealed ductwork or a shared outdoor unit can introduce dependencies beyond the affected room. Explain operating hours and critical periods before arranging the work window.

For replacement, compare the full installed solution: plant, connections, controls, associated work and commissioning. A product price alone does not describe the cost of bringing the system into operation.
