We take health and safety incredibly seriously, ensuring that all employees and clients are kept safe and secure at all times.

We implement the safety passport/skill card policy and train every one of our site personnel and management staff in the working of our safety systems to ensure that our high quality and safety standards are met during every installation, maintenance or servicing project.

All of our health and safety systems have been designed and approved by our independent safety consultant. These include:

  • Safety method statements
  • Risk assessments
  • COSHH assessments

In addition to the above, we also work with trade and professional associations to ensure that we are fully committed to providing you with an accredited and proficient service.

R22 Advice

R22 is an HCFC widely used in air conditioning systems, making it the most commonly used version today. It has been proven that the chlorine in HCFCs is contributing to the depletion of the ozone layer and since 1st January 2010, it has been made illegal to produce or stock virgin R22. Since then, only recycled R22 has been available.

However, on 1st January 2015, all versions of R22 were banned, meaning commercial and industrial business owners had to find other ways of powering their heating and cooling units.

There are currently two options for those business owners needing alternatives to the newly banned substance; Direct replacement & Drop-in refrigerants

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 Electric patented Replace Technology enables part replacement, where the air conditioning equipment is replaced but the existing pipework and electrical system is retained.

In both systems, the new inverter driven R410A & R32 air conditioning unit is used, offering energy savings of around 50%, compared to R22 driven systems.
The decision about whether to carry out part of full replacement will be affected by 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 pipework 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 than 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

Drop-in refrigerants

Alternatives to R22 are available, including 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 and temperature readings.
These products could also 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.
The 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 filled with recycled R22.
