With the R22 phase-out period now over, the use of recycled or virgin HCFCs to service HVAC equipment is now illegal. Daikin UK reminds installers of the new legislation requirements.

Users of HVAC systems have had four years to switch over to non-HCFC substances, following the prohibition of 'transitional' HCFC refrigerants like R22. Many smaller businesses such as retail, offices and hotels may have found it difficult to adapt their systems to comply with the legislation, according to Daikin UK. 

"Businesses that have struggled to make their HVAC equipment fit for purpose by now are facing increased business risk as a result of non-compliance with national and European ozone and F-gas regulations," warned Daikin UK's product manager, Martin Passingham. He urges affected businesses to opt for a new system installation as the most reliable long-term route.

"The capital outlay for an overhaul may have struck some owners as prohibitive," he said. "Others may not have been made sufficiently aware of the looming R22 ban. Either way, these organisations immediately need to expedite their planned system updates or initiate an appropriate course of action if they do not wish to risk not having an operational air conditioning system.

"A system replacement clearly presents the most reliable solution to comply. While with some systems it is possible to move to the use of drop-in HFC refrigerant that is compatible with the system's existing oil, such retrofits may compromise system performance. Installers should therefore recommend replacement technology to hotels and retailers, for example, since their business success largely depends on the flawless operation of HVAC equipment and a balanced indoor climate."
