Where existing air conditioning equipment is suitable for continued use, recommissioning may provide an alternative to complete replacement. We assess systems that have been disconnected, relocated or altered during refurbishment works and establish what is required before they can return to service.
Suitability depends on the age and condition of the equipment, manufacturer requirements, refrigerant type, pipework condition and whether the system has remained adequately protected while disconnected.
Typical recommissioning activities
- Confirm indoor and outdoor unit compatibility and inspect the equipment.
- Assess existing refrigerant pipework for sizing, condition, contamination and suitability for reuse.
- Inspect interconnecting cabling, controls, condensate drainage and relevant electrical connections.
- Carry out appropriate pressure and leak testing, evacuation and dehydration where circuits have been opened.
- Establish refrigerant charging requirements and complete functional and operational checks.
Can existing copper pipework be reused?
Not in every case. Unsealed pipe ends can admit moisture and debris, while older pipework may be unsuitable for the intended equipment or refrigerant. We assess reuse on a case-by-case basis and may recommend replacement where necessary.
Projects we support
Recommissioning enquiries commonly arise after office alterations, domestic renovations, temporary equipment removal, changes to pipe routes or the relocation of indoor and outdoor units.
