Anyone that owns, or has benefitted from, air conditioning units will agree that they are pretty great things. Not only do they provide the cool air we need when temperatures are soaring, they can reduce humidity to keep us comfortable and filter the air so that allergies do not flare up.

One of the only downsides to air conditioners is the fact that they must be regularly maintained. However, if you know what you’re doing, keeping the filters, coils, and fins in perfect working condition will not prove a problem. As we are all about providing the best service for our customers, here is the GMC Aircon guide to maintaining air conditioning units.


Air conditioning filters


All air conditioning units have filters that must be routinely cleaned or replaced to ensure the efficiency and performance of a system. Filters often become clogged with dirt, preventing optimum airflow, which in turn affects efficiency greatly. The longer filters are left unchecked, the more performance will decrease. When airflow becomes obstructed, air can often carry dirt into the evaporator coil, affecting the heat-absorbing capabilities of the machine and leaving you with a warm and sticky room!

By cleaning or replacing a clogged filter, efficiency can be improved by as much as 15 per cent. For room air conditioning units, the filter can generally be found in the grille. For central air conditioners, filters will be trickier to access and are typically located in the wall, ceiling or inside of the air conditioner itself.

Depending on your type of air conditioning system, you may be able to reuse the filter. If you need to replace a filter, you will usually find that they are inexpensive. Always check the filter of your air conditioner every 1-2 months.


Air conditioning coils


Like the filter, the evaporator and condenser coils of air-conditioning units tend to collect dirt over time. A clean filter will help reduce the dirt collected by the evaporator coil, but not completely. If your condenser coils are located on the outside of the building, you may notice that dirt can build up quicker; however, this can be prevented with a once or twice yearly clean. Always try to minimise the dirt and debris near an air conditioning unit. In addition, it can be worth investing in a ‘fin comb’ to help repair bent coil fins.

Unclogging drains


A unit’s drain channels can often become clogged, which will affect humidity reducing capabilities. This can be easily fixed by passing a stiff wire through the channels.



Airconditioning seals


In the cooler seasons, you should take the time to check on the seals between the air conditioner and the window/wall. A routine inspection to make sure the frame is in contact with the system’s casing will prevent moisture from breaking a seal and allowing cold air to escape a room.


Professional maintenance


For smaller air conditioning units, maintaining a system is fairly straightforward; however, for large industrial units used for businesses and schools, it is worthwhile investing in professional help – this is something we can help with. An experienced air-conditioning technician will be able to find and repair any problems and ensure that a system is working as it should. You can also check out our guide here on benefits of airconditioning systems.

Air conditioning units are essential in helping people cope with the hot conditions; by carrying out regular maintenance, you will be able to benefit from cool air all year round!
