Gas Maintenance Matters

Checking that your heating, ventilation and air conditioning (HVAC) systems are working as intended will help to prevent them from using energy ineffectively and also lower the risk of breakdown (the cost of which can spiral out of control!). In this way, regular maintenance of equipment and controls makes good business sense. Read on to find out how you can save money by keeping your systems maintained…

In order for them to operate efficiently HVAC components must be kept free of dirt and other obstructions. The overall system should be serviced annually. Routine maintenance should be regularly undertaken to identify potential problems at an early stage. Evans Maintenance can service a wide range of HAC systems, but if your not sure whether our services are right for you simply give us a call.

Did you know that energy consumption could increase by up to 30% if regular maintenance is not undertaken? Maintenance and energy management go hand in hand- both have the same objectives:

-Ensuring a building and its services continue to function reliably, efficiently and effectively.

-Ensuring the health, safety and comfort of occupants.

-Protecting and enhancing the value investment in a building and its equipment.


Regularly servicing your boiler is extremely important. Gas fires should ideally be serviced once a year; oil boilers twice a year. A regularly serviced boiler can save as much as 10% on annual heating costs!


Condensers are usually located on the outside of buildings and disperse heat that has been removed from inside the building by the cooling system. You must ensure condensing and evaporating devices are clean and well maintained. Make sure you check that condensers are not obstructed, for example by equipment or vegetation, as this will lead to malfunction.

Air Conditioning and Comfort Cooling Plant

By ensuring your cooling plant is regularly maintained you will avoid operating at reduced levels of efficiency. An important factor to remember when servicing your cooling plant is to replace insulation on refrigerant pipework. This is because poor condition will affect the temperature of the refrigerant flowing through the system and thus consume more energy by maintaining the required temperature. Pay specific attention to pipework located outside a building- make sure there are no leaks.

Fans, Filters and Air Ducts

Want to improve efficiency by up to 60%?

There is no point in having an efficiently running system if the air conditioned air gets stopped by a solid wall before getting where it is needed. Blockages in HVAC systems are common and increase running costs, so make sure that the filters are regularly checked. You could consider fitting pressure gauges to your ducts that will let you know when replacement filters are required.


Boilers, hot water tanks, pipes and valves should be insulated to prevent heat escaping. A return can usually be expected within a few months of installation with continued savings in subsequent years.


Heat exchangers and cooling tower water treatment processes should be spotless. This saves energy and prevents health problems such as Legionella.

Don’t be afraid to ask if you think your system isn’t operating correctly. If staff complain about problem areas in your building, act on it immediately. Get in touch!
