Split AC Replacement in London & the M25

Split systems pair one or more indoor units, usually wall-mounted, with an outdoor condensing unit. Multi-split systems connect several indoor units to one outdoor unit.

They are common in small offices, shops and restaurants, and most faults relate to dirty filters, blocked drains, refrigerant leaks or failed fans and control boards.

Every visit is scoped to the equipment and the problem in front of us. For split ac replacement, 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 split AC 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 meeting rooms, comms cupboards, small offices, retail units 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.

We focus on commercial premises, so our engineers are used to working around trading hours, food safety requirements, tenants and facilities teams. You get a named point of contact, clear explanations in plain English and a written record of what was found and fixed.

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 split AC 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.

Keep outdoor units clear of leaves and storage; restricted airflow reduces cooling capacity.

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