F-Gas & maintenance FAQs
How often is leak checking required?
It depends on the type of refrigerant and the system’s CO₂ equivalent charge. We’ll review your equipment and advise the correct interval based on current F-Gas regulations.
Do you maintain F-Gas records for us?
Yes. We can maintain F-Gas logs for each system, including leak test dates, refrigerant additions/removals and engineer details, helping you stay compliant and ready for audits.
Can you take over existing systems from another contractor?
We regularly take on existing sites and equipment. We’ll assess the current condition, review any records you have, and then propose a maintenance schedule and F-Gas log structure going forward.
Do you cover both AC and refrigeration?
Yes. We maintain air conditioning systems (splits, multi-splits, VRF/VRV) as well as cold rooms, freezer rooms, chillers and other refrigeration plant.
