Chiller Fault Finding in London & the M25

Chillers produce chilled water or glycol that is pumped to fan coils, air handling units or process equipment. Air-cooled and water-cooled designs serve offices, hotels, hospitals and industrial sites.

Chiller downtime can affect a whole building or process, so planned maintenance, water treatment and fast fault response matter.

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

If you notice any of the following on your chiller, it is worth arranging a visit before a minor issue becomes a breakdown.

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

We work with hospitals, data centres, manufacturing, food and drink production 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.

Commercial customers need more than a quick fix. We explain what has failed and why, give you clear options before extra work goes ahead, and leave written records that help with audits, insurers and future maintenance planning.

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 chillers 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.

Trend chilled water temperatures over time; gradual drift is an early warning of fouling or charge problems.

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