Most chiller breakdowns start as small, measurable changes: a slow refrigerant leak, a fouled condenser, a tired contactor. A proper maintenance plan catches them before they stop your production.
Based in Oldbury, we maintain process chillers for manufacturers across the West and East Midlands.
Step 1
An engineer visits, assesses your chillers and looks at their fault history.
Step 2
We recommend the right interval and plan, with clear pricing and no obligation.
Step 3
Visits are scheduled around your production, with a report after every one.
Each visit follows a structured technical procedure, and you get a written report afterwards with any issues ranked by priority.
These are the four faults we are called out to most. All of them give warning signs a PPM visit is designed to catch.
Compressor damage is rarely sudden. Poor oil return, high discharge temperatures, short cycling and refrigerant loss all show up in readings long before the compressor fails. A compressor replacement is one of the most expensive repairs on any chiller. Catching the cause early is far cheaper.
Pressure trips are usually a symptom of something developing: fouled condensers, scaling in water-cooled systems, gradual refrigerant loss, a blocked expansion device or poor flow across the evaporator. Repeated trips stress the compressor and destabilise your process temperatures.
Pump wear, blocked strainers, air in the system and incorrect glycol concentration all cause flow problems. They usually start as occasional nuisance alarms before turning into a full shutdown. See our glycol concentration guide.
A chiller can look like it is running fine while its performance quietly declines. Dirty heat exchangers, the wrong refrigerant charge and drifting sensors push up running costs without ever triggering an alarm.
There is no single right answer. The right interval depends on how critical the chiller is and how hard it works. Most sites fall into one of three patterns:
Standby chillers and low-risk systems where a short outage would not stop production.
The most common pattern. Moderate-load systems, with a pre-summer and pre-winter visit.
Process-critical and high-load chillers running around the clock, where downtime is expensive.
Whatever service interval you choose, chillers containing F-Gas refrigerants must be leak checked by certified engineers at intervals set by law. The interval depends on the refrigerant charge in tonnes of CO2 equivalent: typically every 12 months for 5 to 50 tonnes, every 6 months for 50 to 500 tonnes, and more often above that unless automatic leak detection is fitted (GOV.UK guidance). We build these checks into your PPM schedule and keep the records for you. See our guide to F-Gas compliance for chiller operators, including a leak check calculator.
We will recommend the right interval for each chiller after a free site survey.
Every plan is built around a maintenance schedule tailored to your site. The difference is the level of response and support around those visits.
Fixed pricing agreed up front. Contracts from 1 to 5 years. Flexible payment options available.
Structured maintenance and compliance, for stable systems where a short delay in response would not stop production.
Everything in Standard, plus reduced downtime exposure, for process-critical systems where a cooling failure stops production.

“I work for OCS at the British Geological Survey, where Evolution Cooling Limited has been responsible for maintaining our chillers and air conditioning units. I’d like to extend a special thank you to Andy Turton, whose hard work and expertise consistently shine through. Andy is extremely knowledgeable, always professional, and provides a high standard of service.”

“Evolution Cooling have been exemplary in the quickness of response, knowledge of the units within site and dedication and commitment to ensure minimal disruption to our manufacturing process. I would highly recommend Evolution Cooling Ltd, so much so, that they have taken over our service contract.”

We will:
To help us quote quickly, tell us how many chillers you have, the make if you know it, and your site postcode.
Yes. We regularly take over service contracts from other providers. We start with a free site survey to get to know your chillers and their history, then plan the handover so there is no gap in cover.
Contracts run from 1 to 5 years, with fixed pricing agreed up front and flexible payment options available.
Yes. We pick up your existing records and continue them, so your leak-check history stays complete for audits.
It depends on how critical and how heavily loaded the chiller is. Standby and low-risk chillers are usually serviced once a year, most moderate-load systems twice a year, and process-critical chillers running around the clock quarterly. F-Gas leak checks are also required by law at intervals based on the refrigerant charge.
Refrigeration pressure, superheat and subcooling checks, flow verification, compressor and oil condition, electrical and control panel checks, evaporator and condenser cleaning, F-Gas leak checks, safety device testing, alarm history review and sensor calibration. You receive a written report after every visit.
The cost depends on the number and size of chillers, how many refrigerant circuits they have, access, visit frequency and whether you choose the Standard or Priority plan. We provide fixed, transparent pricing after a free site survey.
A well-maintained industrial chiller commonly lasts 15 years or more, but it varies with operating hours, environment and how well it has been looked after. Regular maintenance is the biggest single factor in reaching the upper end of that range. See repair, replace or upgrade.
We are based in Oldbury in the West Midlands and maintain chillers across the West and East Midlands. We also take on planned maintenance contracts further afield by arrangement.
We aim to have an engineer on site within 4 hours of your call, depending on location. Contract customers are prioritised, and Priority Plan customers have 24/7 cover. See our emergency breakdown service.
All major manufacturers, including Trane, Carrier, Daikin (including McQuay), Mitsubishi Electric, Climaveneta, RC, York, Lennox, Aermec, Airedale, Blue Box, Clint, ICS Cool Energy, MTA, Rhoss, Hitema, Thermocold, CF Chillers and KKT, plus process and machine-tool chillers from Frigel, Piovan and Aquatech, Parker Hiross and Hyperchill, Eurochiller, technotrans, Hyfra, Pfannenberg, Rittal, Riedel, Ritter-Badder, Habor, TPC, Cosmotec, Tongfei and Burn Engineering. We stock spares for MTA TAE EVO 015 to 602 units. See our dedicated page on MTA chiller service, repair and spares.
Most chillers have a manual reset on the high-pressure switch inside the unit, or a reset on the controller. One reset is reasonable, but if it trips again, leave it off and call us: repeated resets can damage the compressor. Our team can talk you through it on 0121 820 8946.
Most often a refrigerant leak. Other causes include a failed expansion valve or solenoid, a frozen heat exchanger or low glycol concentration. See our guide to low-pressure problems on chillers.
