Our HVAC Capabilities
Air Conditioning Maintenance & Repairs
We service all types of commercial air conditioning systems, including VRV/VRF, split, and multi-split systems. Our planned maintenance (PPM) services improve efficiency, maintain F-Gas compliance, and reduce the risk of mid-season failures. We also offer rapid-response repairs for urgent issues.
Chiller Maintenance & System Support
From air-cooled and water-cooled chillers to plantroom-based cooling systems, we provide comprehensive servicing and repair. Our chiller engineers handle refrigerant management, compressor diagnostics, and control panel fault finding to keep your system running smoothly all year round.
Commercial Heating Maintenance & Repairs
We maintain and repair a wide variety of commercial heating systems, including gas boilers, heat pumps, and LTHW circuits. Services include burner inspections, flue gas analysis, sensor testing, and control system repairs—ensuring your heating remains compliant, reliable, and energy-efficient.
PCB Repairs & Control Fault Diagnostics
Control board faults are one of the most common causes of HVAC failure. We carry out on-site PCB diagnostics, repairs, and replacements for air conditioning, chillers, and heating equipment—restoring performance without full system replacement. Our engineers are experienced with a wide range of board types, from inverter PCBs to fan speed modules and controller displays.
