Inverter systems have compressors that vary their capacity depending on what is actually required. When you need more heating or cooling, the inverter compressor speeds up, when you need less it slows down, rarely stopping completely and therefore draws a smaller electrical load. Industry experts suggest that inverter systems can save up to 40% on running costs compared to a non-inverter system. With Non-Inverters, the compressor starts at full power; when temperature is reached, the compressor stops. The cycle is then repeated throughout use, drawing more electrical current.
Most systems are registered on the energy technology list which enables clients to qualify for up to 100% first year allowance on the total cost of the system www.eca.gov.uk.

Heat Pumps
Heat pumps are an integral part of air conditioning technology. Heat pumps transfer heat from one environment to another via its refrigerant. In cooling mode, air conditioning units transfer the heat in an enclosed area to the outside air, resulting in a cooling of the area in question. Heat pumps, however, also allow this process to be reversed. Heat extracted from the outside is pumped indoors, allowing indoor environments to be heated as well as cooled using the same technology.

F Gas Regulations & Leakage Checking/Repair
Leakage checking/repair
End users will be required to use all available measures to prevent leakage of F-gases and to repair any detected leakage (as soon as possible); a system found to have a leak must be switched off immediately and not used until the problem has been rectified. Any repair must be re-checked for leakage within one month. The Regulation also provides a timetable for leak testing equipment and systems with a charge of 3kg or more:

Any repair must be re-checked for leakage within one month. The Regulation also provides a timetable for leak testing equipment and systems with a charge of 3kg or more:
- At least once a year for applications containing 3kg or more of F-gases (this does not apply to hermetically sealed systems containing less than 6kg).
- At least once every six months for applications containing 30kg or more of F-gases.
- At least once every three months for applications containing 300kg or more of F-gases. In addition, these systems will be required to have permanent leak detection systems installed.
F-Gas Regulations
EU Legislation, F-Gas Regulation 842/2006, came into force in July 2007.
Below is a summary of the Regulation which details the responsibilities it imposes on us as the supplier and the end user.
F-gases (fluorinated gases) are global warming gases which have come under the spotlight of the EC's Kyoto Protocol targets. The basic objective of the new legislation is to reduce emissions of these global warming gases from air conditioning and refrigeration equipment. F-gases include all HFC Refrigerants, including R134a, R407c, R410a and R404a.
The main points of the new law include:

- Refrigerant records
- Equipment labelling
