All air conditioning and refrigeration systems contain refrigerant, which is most commonly referred to as ‘gas’ or even ‘freon’. This gas is contained inside the system and is pumped throughout the system by the compressor. In an ideal situation the refrigerant would never leak out but when this does occur, your system can fail or at the very least lose efficiency, and, as importantly, the leaked refrigerant moves in to our atmosphere. This can cause damage to the ozone layer and add to global warming – this is why all refrigerants are rated with Ozone Depleting Potential (ODP) and Global Warming Potential (GWP) ratings. The best cure is prevention, as they say, and a good maintenance regime, and following best practice when handling refrigerants, can significantly reduce refrigerant escaping to atmosphere.
To assist in limiting and reducing the incidence of leakage, and therefore the damage this can create, the F Gas regulations have been introduced.
F-Gas regulations were brought in to make sure all refrigerant is handled by competent engineers and to make sure it doesn't leak from air conditioning systems into the atmosphere. All engineers should have an F Gas certificate and all respectable companies should have REFCOM certification. Hertfordshire Air Conditioning is pleased to say we are REFCOM accredited and all our engineers are F Gas certified!
But what does this mean for you, and other users or owners of Air Conditioning systems? Well, any air conditioning systems with 3KG of refrigerant or less are not covered under F Gas legislation, though systems containing over 3KG of refrigerant MUST have leak testing carried out on them and records MUST be held. The frequency of leak testing varies depending upon the total weight of refrigerant in your system(s) but will range from once a year to four times per year. Your Air Conditioning company is also obliged to complete an F Gas sheet stating how much refrigerant has been removed from a system, or added to it, in event of any service work and this sheet must be placed in your log book.
Is your service company REFCOM accredited, and their engineers F Gas certified? Do you have your units leak tested at least once per year? Do you know how many times per annum your units require testing, or how much refrigerant is contained within your systems? Has your service provider offered to give you sheets after they’ve removed, or added, refrigerant to your system and, if not, have you asked them to? Have you got a log book on site in which you can house your reports?
