AC Leaking Refrigerant in London & the M25

AC refrigerant services cover leak detection, repair, recovery, evacuation, regassing and F-Gas leak checks on split, VRF, rooftop and chiller systems.

Low refrigerant always means a leak. Recharging without finding and fixing it leads to repeat call-outs and potential compliance problems.

When the problem is "ac leaking refrigerant", the cause can sit in several places. The engineer will check the simplest and most likely causes first, then move on to components and the refrigerant circuit.

In the meantime, check that the power supply is on, the set point has not been changed, vents and coils are not blocked and doors are closing properly. If stock is at risk, move it to working storage and record temperatures for your food safety records.

Every visit is scoped to the equipment and the problem in front of us. For ac leaking refrigerant, the work typically includes the following, with any extra work explained and agreed before it goes ahead.

These are the problems we see most often on AC refrigerant systems across London and the M25. Many start small and get worse if left.

A proper visit goes beyond fixing the obvious symptom. Depending on the equipment and the agreed scope, the engineer will check:

We work with server rooms, public buildings, offices, retail and many other commercial premises across London and the M25. We understand that equipment often has to be worked on while you are trading, so we plan visits to minimise disruption and keep areas clean and safe.

Multi-site operators and facilities managers can group equipment into one maintenance schedule, with consistent records across sites.

Air conditioning systems using fluorinated refrigerants fall under the F-Gas Regulations, so refrigerant handling, leak checks, recovery and recharging must be carried out by suitably certified engineers and recorded. Larger systems with an effective rated output above 12kW also need a TM44 air conditioning energy inspection at least every five years, which building owners and managers are responsible for arranging.

After the visit you receive a record of the work carried out, readings taken where relevant and any recommendations, which you can keep with your maintenance and compliance documents.

Booking is straightforward and we keep you informed at each stage.

Our approach is simple: turn up prepared, diagnose properly, explain the options clearly and record the work. That keeps repeat visits down and gives managers the information they need to budget for maintenance and replacements.

We also provide commercial gas safety certificates, catering equipment servicing and air conditioning work, so sites with several types of plant can deal with one contractor for planned visits and compliance paperwork across London and the M25.

Not every fault justifies a repair. Where AC refrigerant systems are old, use a refrigerant that is being phased down, or keep failing, the engineer will tell you honestly whether a repair is good value or whether planning a replacement makes more sense. Age, energy use, parts availability and the cost of downtime all feed into that decision.

For equipment worth keeping, a planned maintenance schedule matched to how hard it works is usually the most cost-effective way to avoid emergency call-outs and keep running costs down.

Ask for leak check records after every visit; they form part of your F-Gas compliance history.

Keeping a simple log of temperatures, alarms and faults also makes diagnosis faster and helps spot patterns before equipment fails.
