Company History

In 2003, after working for a market leader HVCA company for some 15 years, Michael Stewart left to set up Aircool Systems in a small office at his home. Over the last 10 years, Michael has grown Aircool Systems into a reputable company within the industry and secured big contracts with facility companies, NHS Hospitals and other long-standing businesses.

He places great emphasis on creating and maintaining a close business relationship whether it is an individual wishing to improve their home, to small local businesses and large international corporations.

Aircool Systems (Southern) Ltd are currently based in Kent but cover all over the South East and London including all Home Counties.
We offer Installation, Maintenance, Service and Technical Support on all aspects of HVCA and our team of direct employed Technicians, Engineers and Fitters, all mobile with fully equipped vehicles, undertakes all works.

Aircool Systems (Southern) Ltd are proud to be in partnership with Mitsubishi Electric.

Mitsubishi Electric Living Environmental Systems are a market leader in providing solutions to heat, cool and ventilate our world. As a major manufacturer of some of the pivotal technologies, we hold the UK’s energy challenges close to our heart. We want to help the nation achieve its climate goals; we want to help individuals and businesses reduce the energy consumption of their buildings, whilst helping to reduce their running costs.

Founded in 1921, with many of those years spent at the forefront of the industry, we have led the way in the use of innovative, energy efficient, heat pump technology. Mitsubishi Electric has evolved, and today our areas of expertise go way beyond advanced air conditioning systems that formed the foundation of our business.

As the need to improve energy efficiency and reduce carbon emissions impacts on every sector, the company remains the only manufacturer to reject any major growth in the UK’s residential air conditioning market as unnecessary and unsustainable. Instead, Mitsubishi Electric is leading the market in the provision of low carbon residential heating systems, with its award-winning Ecodan® air source heat pump which can help homes achieve level 3 and 4 of the Code for Sustainable Homes.

In addition to the residential sector, Mitsubishi Electric has used its specialisation in heat pumps to develop a range of Ecodan commercial heating systems which rival traditional heating methods (in terms of performance and acceptability), whilst meeting renewable legislation, cutting running costs and reducing carbon emissions to deliver sustainable, low carbon heating.

The development of energy efficient buildings through the supply of renewable energy from micro generation technologies remains a long-term goal of the company under its framework for realising a sustainable planet – Environmental Vision 2021. This stands at the core of Mitsubishi Electric’s commitment to the environment, and outlines targets that the company aspires toward and that it measures itself against.

Replace Technology & The R22 Ban

R22 is an HCFC widely used in air conditioning systems making it the most common HCFC in use today. The chlorine in HCFC’s is ozone depleting and since 1st January 2010 it has been made illegal to produce or stock virgin R22. Only recycled R22 was available since then however, since 1st January 2015, all R22 is banned.

There are two main options regarding the ban on R22
Direct Replacement Drop-In Refrigerant
Drop-In Refrigerants

Alternatives to R22 are available, such as R422D and R417A. As the name suggests, these products are dropped in as a replacement for the R22. There are however significant potential problems with using the drop-in refrigerants. For example, they have different pressure-temperature characteristics to R22, which can confuse the embedded system software, giving erroneous pressure/temperature readings. These products could potentially create unstable air conditioning systems, leading to deterioration of many parts within the system. This could lead to catastrophic system failure such as compressor burnout or seal failures.

Risks include:

  • Suboptimal air conditioning system performance Poor frost/defrost
  • Creation of dew condensation and dew spray
  • Possible corrosion risks
  • Possible leakages
  • Possibility of compressor failure
  • Recycled R22 can only be used in air conditioning systems for servicing and maintenance purposes, and from January 2015, R22 systems can no longer be re-filled with recycled R22.
  • Direct Replacement

There are two options regarding R22 air conditioning system replacement, full or part replacement. Full replacement involves the replacement of all air conditioning equipment and component parts. Mitsubishi Electrics patented Replace Technology enables part replacement, where the air conditioning equipment is replaced but the existing pipe work and electrical system is retained. In both systems, the new inverter driven R410A air conditioning used are used, offering energy savings of around 50% on R22 driven systems.

The decision on part or full replacement will involve a number of factors:

  • How old is the air conditioning equipment
  • What is the operating state of the equipment
  • Is there a strong maintenance history on the air
  • conditioning system
  • Is the pipe work in good condition
  • What is the payback period for the replacement system?

2003 was the last year in which high volume R22 sales were made and even then, this was less than 20% of the total market volume. Thus many R22 driven air conditioning systems will now be approaching, if they have already not exceeded, 10 years of age.

Several conditions arise when evaluating the payback period for the R22 system replacement:​

  • The energy efficiency of old equipment is far less then it was when it was originally installed, irrespective of maintenance.
  • The new R410A driven air conditioning systems are inverter driven, giving reduced running costs and closer comfort levels.
  • The R410A air conditioning systems are circa 50% more energy efficient than the old R22 based systems.
  • Rapidly rising energy costs throw energy efficiency into sharp focus
