Mr Stilling joins Bristol-based A-Gas from Carter Synergym where he managed a team in the service sector and worked closely with supermarket retailers.
His new role at A-Gas will see him maintaining and growing relationships with major wholesalers.
Mr Stilling said: “I am delighted to be a part of the fast-expanding A-Gas business at a time of great change in the industry. The F-Gas Regulations continue at a pace and helping customers make the switch to lower GWP refrigerants, and get the benefits associated with reclaimed gases, will be high on my agenda. I shall be working closely with wholesalers across the UK to ensure that the needs of customers are met.”
