Do you have spare parts for all manufacturers?
Cooltherm supplies parts for all mainstream chillers and compressors. Contact the team today and we will happily source your requirements.
What suppliers do Cooltherm work with?
We specialise in delivering bespoke air conditioning and cooling solutions and will work with a broad range of industry leading suppliers to ensure we have the right product solution for you. No project is too complex logistically or technically advanced.
I need help finding a low GWP refrigerant, could Cooltherm help?
Yes of course, The Cooltherm team developed a Continuing Professional Development (CPD) module focusing on two critical aspects: R290 and the HFC refrigerant phase-down. R290, a natural refrigerant with a GWP of just 3, has gained significant attention due to its energy efficiency and low environmental impact. It is a suitable alternative to hydrofluorocarbon (HFC) refrigerants, which are currently being phased down globally due to their high global warming potential. We can talk you through the different options and find the right solution to meet your carbon reduction targets.
What types of HVAC and chiller systems does Cooltherm service?
Cooltherm are available to service and maintain a wide range of HVAC systems and chillers, regardless of make and model, within a variety of sectors.
Existing customers include those within healthcare, manufacturing, education, as well as large-scale commercial properties such as corporate offices.
We are, however, proud to be official partners of two of the largest equipment suppliers in HVAC: Mitsubishi and Daikin.
Cooltherm have been awarded Daikin D1+ Partners by virtue of our top-quality service capacity and product knowledge.
And the exceptional quality of bout our design ability and workmanship saw us awarded the title of Mitsubishi Diamond Quality Partner.
Being welcomed into the Carver Group portfolio of companies further bolsters our service and maintenance capacity and means we can support with products from the Biddle and Thermoscreens brands.
If you need support with your HVAC and/or chiller solutions, Cooltherm can help. Contact us today and let us help.
How often should I schedule maintenance for my HVAC system?
Standard practice is to schedule a full service of your HVAC equipment once a year at a minimum. And if the load on your HVAC is particularly great, for instance if your system is deployed to rigidly maintain temperature and humidity, a service every six months would be advised.
Scheduled servicing can reduce downtime as actions can be placed ahead of time to mitigate any disruptions. However, issues may arise spontaneously regardless of the frequency of maintenance. That is why Cooltherm recommend conducting regular checks of your HVAC.
What is included in a Service & Maintenance contract with Cooltherm?
When you take out a Cooltherm Service & Maintenance contract you can be assured that your equipment is supported by some of the most knowledgeable people in the realm of HVAC and chillers.
The Operational Support Team are on hand to provide remote assistance if required, deploying their advanced expertise to help you determine any issue or potential fault.
Should a callout be required, they can arrange for a mobile engineer to visit anywhere in the UK. A thorough detailed description of the unit, its function, and the known fault will be provided along with any necessary risk assessments so their visit it a streamlined as possible.
Service & Maintenance contracts are customisable, and developed alongside our customers to curate coverage that precisely matches their requirements.
Contracts can also include 24/7 emergency callout cover, in the event of a sudden malfunction of your equipment.
Can Cooltherm provide emergency repair services for broken HVAC or chillers?
24/7 emergency callout services are only available to those who have selected that option in their maintenance contract.
Callouts can be scheduled if required but are subject to a charge.

What are the signs that my HVAC system might need repair or maintenance?
At Cooltherm, routine checks of your HVAC and chillers are recommended to take place as part of any facility monitoring.
To support that, here are some basic measures you can identify that may need further support:
1. Unusual Noise: can you hear a rattle or a grind or a squeak? If so, this may be because of a mechanical issue.
2. Poor air flow: Stood below the vent and struggling to feel something? Could indicate a block in the ducts or an issue in the unit.
3. Unusual Odour: Could mean that it is damp inside the ducts, that the filter is blocked up, or dust has been accumulating within the system.
4. Visible leaks: Whether it is moisture within the ceilings or refrigerant from the equipment, any visible leak will need urgent review.
5. Temperatures not matching up: If your BMS or thermostat is set to a particular temperature but that is not corroborated with a thermometer, there could be issues with sensors, the heating/cooling elements within the equipment, or the thermostat itself.
If you spot any of the above, please do get in touch and we can arrange for a visit to determine the cause and suggest the best resolution.
Does Cooltherm offer environmentally friendly solutions for HVAC systems?
Yes. At Cooltherm we pride ourselves on our ability to source and provide low-carbon HVAC and chiller solutions.
With high GWP refrigerants facing an aggressive phase out campaign, we are keeping abreast of changes in legislation to ensure we can provide the optimal solution with more environmentally friendly alternatives.
Moreover, our chiller and air handling units are among the most efficient in the market, meaning much less energy is needed to provide your building(s) with the perfect internal environment.
What are the core components of a chiller?
The refrigeration cycle within a chiller commonly consists of an Evaporator, a Compressor, a Condenser, and an Expansion Valve:
Evaporator
This is the area in which heat is removed from the process water by the refrigerant. The refrigerant will have a boiling point far lower than the process water, meaning the heat exchange causes the refrigerant to become a vapour before reaching the compressor.
Compressor
Component within the chiller which increases refrigerant pressure and, therefore, further increases its temperature.
Condenser
Here the heat energy from the pressurised refrigerant is dumped from the cycle. Depending on the type of chiller deployed, refrigerant is cooled by a water tower, or by fans blowing cooling air over the refrigerant.
Expansion Valve
Despite the heat exchange within the condenser, the refrigerant still needs to relieve pressure. The expansion valve reduces the pressure of the refrigerant which, in turn, reduces its temperature – ready to be used in the evaporator once again.
