The guide also looks briefly at air handling units and the F-Gas Regulation and how these impact on maintenance.

Other sections explain how to keep equipment clean and free from airborne debris, tips on good housekeeping, chiller maintenance and coil servicing.

Providing useful tips for building services installers and maintenance engineers, the guide provides practical information on how to ensure HVAC plant is running efficiently – essential for reducing energy consumption, extending asset life and increasing operational certainty.

John Grenville, managing director of ECEX, said: “Proper HVAC maintenance that is predictive and fit for purpose is an investment worth making, reducing costs across the board from energy savings to avoiding expensive repairs and replacements, not to mention the damage breakdown can do to a business' reputation.

“When it comes to AHUs, for example, there are compelling reasons to choose maintenance over replacement – just 35-50 percent of the cost of a new unit according to some estimates. AHU maintenance also offers the opportunity to enhance the existing specification by taking advantage of the latest energy efficient EC plug fans and components. This is an area in particular that we are investing in as a company, with the introduction of our new contracts manager, Ryan Hawken. Ryan has a special responsibility for air handling units (AHUs).”
