A good installation starts with a survey of the space, loads, power supply and positions for equipment, followed by careful installation and commissioning. Sharing the make, model and a photo of the rating plate in advance helps the engineer arrive prepared.

This page explains what split ac installation involves, the faults and checks we commonly deal with, how we work on commercial sites, and what you need to know about compliance before booking.

About Split AC Systems

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.

What Split AC Installation Includes

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

  • Site survey and design advice
  • Supply and installation
  • Pressure testing and commissioning
  • Handover documentation

Common Split Air Conditioning System Problems We Deal With

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.

  • Outdoor unit not running
  • Noisy fan
  • Remote or controller not responding
  • Unit not cooling
  • Water dripping from indoor unit
  • Error code flashing

Checks Our Engineers Carry Out

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

  • PCB and sensors
  • Electrical supply
  • Filters and indoor coil
  • Condensate drain and pump
  • Refrigerant pressures
  • Outdoor coil and fan

Businesses We Support

We work with small offices, retail units, restaurants and cafés, salons and clinics 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.

Compliance, F-Gas and Record Keeping

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.

How to Book Split AC Installation

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

  • Survey: Site, loads and access are assessed.
  • Install: Equipment is fitted, piped and wired.
  • Commission: The system is tested and handed over.

Why Businesses Choose Us for Installation

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.

Planning Ahead: Repair, Maintain or Replace?

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.

Engineer Tip

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.
