Clean Air were recommended to us by my father, who had used them for years fitting, replacing and servicing air conditioning units. Clean Air fitted some air conditioning units in our dental practice. From the minute I rang them asking for a quote they wee professional, friendly and very thorough. The fitting was very tidy and efficiently completed. The units are running brilliantly. We would thoroughly recommend the team! Priya ChadhaTrustindex verifies that the original source of the review is Google. We have used Clean Air Group for a number of years and have found their service excellent. We recently had a new unit installed and the team were great; polite, friendly and very tidy. Laura WellsTrustindex verifies that the original source of the review is Google. This is the first we have used Clean Air Group they installed a new industrial hot air system in our workshop with thermostatically controlled air blower. They were excellent all the way through from initial contact to installation. The guys in the workshop really appreciate temperature consistency. I would highly recommend them Matthew PollittTrustindex verifies that the original source of the review is Google. Very helpful and were able to fix the heater quickly. I would recommend this company and use them again. Julia WallisTrustindex verifies that the original source of the review is Google. Thanks to all at Clean Air for a great and exceptionally smooth service, from initial visit, to survey, installation and aftercare. Nicola SextonTrustindex verifies that the original source of the review is Google. We had an air con system installed in our office by the Clean Air Group. The whole process went very smoothly, from the initial quote to the installation. The guys carrying out the installation worked really tidily and neatly, and I was really pleased with the work. Of course, as they say - " the proof of the pudding is in the eating", and once installed and we were using the system we were delighted with it's efficiency, and with how quiet and smooth running the air con units were. So all in all, excellent throughout the whole process and I would definitely recommend them. Colin SowterTrustindex verifies that the original source of the review is Google. The service from the engineers and the overall company, is first class. Used them for over 20 years and they are so reliable. Keith WTrustindex verifies that the original source of the review is Google. This was the first time dealing with Clean Air group on a big project installing 2 x Evaporative Cooling systems and a heating system. I have to say the professionalism of this company is second to none, right from the very first contact with Ben, he guided me through exactly what we needed and gave the reassurances that such a big investment needed. Literally to a man the team were exceptional, survey through project management with Kyle and of course the way the installs were handled were just brilliant. The project was completed earlier than expected and with clear expertise in this field. The on site engineers were a credit to the company, again nothing was too much trouble and the way they carried out the works was impeccable and safety of anyone near the working area was always at forefront of their mind. I would like to stress that these guys are the best in the business, absolutely delighted with the way it was all handled and would HIGHLY RECOMMEND! Dan JonesTrustindex verifies that the original source of the review is Google. We have now had two Projects done by Clean Air Group over the past 2-3 years. One for a full heating system to the main factory and the other for evaporative Air Conditioning. The first project for heating went so smooth that when we wanted Evaporative Air Conditioning we only asked Clean Air as they are always competitive but more important very professional. The whole experience from Sales, Accounts, Pre Inspection, Fitting and sign off was a delight. I don't do reviews usually but I felt I needed to mention this team. I highly recommend Clean Air Group to you all, they do the complete works, electrics, water, fitting so you have no arguments about oh its the electricians fault etc etc, we have all been their I'm sure. Just trust me the Service and Products are second to none, the engineers/fitters are so helpful and work with you not against you. 5 Stars from us only because I cant give 6. I just want to thank the whole team for Two of the smoothest instals I have ever known. Andy Davis BH Digital Ltd Andy Davis

Across the UK, more businesses are seeking alternatives to gas heating in commercial buildings and alternatives to oil heating systems. Rising energy costs, carbon reduction targets and ESG commitments are driving the shift towards cleaner technologies.
Air to Air Commercial Heating Systems provide a reliable, high-efficiency solution.
Many modern air-to-air heating systems operate using advanced heat pump technology. These commercial heat pumps provide highly efficient heating and cooling by transferring energy rather than generating it through combustion, making them an ideal low-carbon alternative to gas or oil heating for warehouses, factories, offices and retail environments.
These air to air warm air units use refrigerant-based heat pump technology to deliver powerful heating without combustion. By transferring energy efficiently, they cut both running costs and carbon emissions while still meeting the demands of warehouses, factories and large commercial buildings.

The flexible, powerful and discreet way to heat large areas, especially when your floor space is better used for something else.




The Clean Air range of natural gas and LPG boilers provide a high power, low cost answer to a wide range of heating and/or hot water requirements.
Our engineers will design an integrated heating system to meet your specific requirements. Correct specification of heater units is usually just the beginning of good industrial heating design. Airflow will need to be balanced, condensation managed and an advanced diagnostics system installed to monitor and manage performance.
Floor mounted boilers – either condensing on non-condensing – can be supplied as independent units or combined in module ‘arrays’ to provide outputs of up to about 1050kW.
With a range of high/low or fully modulating matched burners these high efficiency, high capacity units deliver robust and economical performance at a reduced cost to the environment.
Convenient and smaller than traditional boilers, wall-hung condensing boilers can be used individually or be combined in multiples to provide an output each of between about 40kW and 150kW. They are also available with frames for floor standing.
Some offer a condensing performance with up to 109% net seasonal efficiency. Fully modulating burners match building loads accurately and ensure efficient energy use. Where modules are combined sophisticated controls optimise sequencing and different temperature circuits – for example, underfloor, radiator or hot water – to meet demand efficiently.
Air curtains help to retain heat and cool air in buildings that have their doors open for long periods at a time. Effectively a fan that blows evenly across the threshold, an air curtain creates a ‘wall’ of air that maintains the temperature inside a building. Whether you choose to heat the air by electricity or hot water, or leave it at ambient temperature, the air curtain will minimise draughts and heat loss and help to conserve energy, potentially cutting your bill.
