Beyond fixing leaks

A complete refrigerant strategy, not a quick patch

As a contractor, we know that fixing leaks is just treating symptoms. We provide a complete expert service, advising on future refrigerant strategies and carrying out full system analysis to ensure your systems maintain performance — protecting you against equipment breakdowns, regulatory penalties and rising energy costs. Leak detection starts at the time of installation: our good practice from day one means every installation is properly tested in accordance with BS EN378, and pressure testing ensures we install a leak-tight system.
