All gas appliances should be serviced and checked on an annual basis. Gas appliances have specific gas pressure and post combustion ratios. Each manufacturer will stipulate these ratios for their appliance. On an annual service, our commercial gas engineers will use calibrated equipment to identify/rectify these readings to be on par with those set out by the manufacturers technical guidelines. A yearly documented service is often a requirement by a manufacturer for their said appliance to be covered it’s warranty. Failure to service an appliance at its required interval, may not just void its warranty, but can also result in combustion readings being incorrect. This may then lead to an higher gas usage as well as the possibility of further expenses in appliance diagnostics and repairs.

Diagnostics & Repairs

An integral part of being a commercial heating engineer is being able to diagnose a fault on an existing system. Faults on heating system can vary from incorrect gas supply pressures, ignition sequences, post combustion and ventilation. In some instances the faults are not specific to an appliance, but are found in wiring centres and electronic hubs sometimes situated away from the actual appliance. Our repair technicians are specialists in tracing and identifying the faults using multimeters and other electronic testing equipment. We will always endeavour to identify and repair a system fault on site and will also provide a quote for the source, supply and install of any specific component if required

Gas Safety Reports

It is the requirement of the responsible duty holder of a site to ensure an annual gas safety report is completed on their gas appliances. This is not only a Gas Safe Register requirement, but is legal requirement by the Health & Safety at Work Act, as well as a requirement by many buildings, contents, public liability and employers’ liability insurance providers. A commercial gas safety report will check for any gas leaks, ensure the appliances are safe to use by checking gas pressures, combustion readings, ventilation requirements and safety devices such as interlock and pressure relief components.

"Excellent service! We had a fairly substantial leak coming through our kitchen floor and MHM Services were able to come and diagnose the problem the same day and returned the next day to complete the work. The work was completed promptly, left tidy afterwards and all for a very reasonable price. We will definitely be using MHM Services again."
