Why You Should Plan Your R404A Replacement Now With UK F-Gas quotas tightening and R404A prices rising significantly, now is the time for refrigeration engineers and facility managers to plan the transition to lower-GWP alternatives. R448A and R449A offer around 65% lower GWP than R404A and are compatible with most existing R404A commercial refrigeration equipment. […]
Refrigerants Used in UK Commercial Chillers Commercial water chillers serve office buildings, hotels, hospitals and industrial processes across the UK. The refrigerant choice for chiller applications differs from split AC and direct expansion systems, with different priorities around efficiency, charge size, flammability and future compliance. R134a — The Legacy Chiller Refrigerant R134a has long been […]
Are All Refrigeration Systems Covered by UK F-Gas Regulations? While UK F-Gas Regulations cover the vast majority of refrigeration, air conditioning and heat pump systems, there are specific categories of equipment and substances that are either exempt or fall outside the main certification requirements. Understanding these exemptions helps engineers and operators identify where standard F-Gas […]
Why Superheat and Subcooling Matter for R32 Systems Setting correct superheat and subcooling is the key indicator of a correctly charged R32 heat pump or air conditioning system. Because R32 must always be charged by weight, verifying these values after charging confirms the system is operating within manufacturer specification and at maximum efficiency. What Is […]

Refrigerant Types Used in UK HVAC Systems UK HVAC engineers encounter a wide range of refrigerant types across heating, ventilation, air conditioning and refrigeration systems. Understanding the classification, properties and correct handling of each is essential for safe, compliant work. HFC Refrigerants — The Current Mainstream Hydrofluorocarbons (HFCs) are the dominant refrigerant family in UK […]
Who Must Keep a Refrigerant Logbook? Under UK F-Gas Regulations, operators of refrigeration, air conditioning and heat pump equipment containing 5 or more tonnes CO2 equivalent of fluorinated gases must maintain a written refrigerant logbook (also referred to as an equipment log or system record) for each system. What Must Be Recorded The logbook must […]
R134a in UK Automotive Air Conditioning R134a has been the standard refrigerant in UK passenger car air conditioning systems since it replaced R12 (CFC) in the early 1990s. Vehicles manufactured before approximately 2017 almost universally use R134a. Post-2017 models use R1234yf. Understanding which refrigerant your vehicle uses is the first step before any AC service […]
