Annual planned preventative maintenance plan
The benefits of the PPM for the receiving business are:
- Higher customer satisfaction because of the comfortable shopping/eating/sleeping environment
- Higher employee satisfaction because of the comfortable working environment
- Higher ROI on the air conditioning equipment by reducing the chances of costly, lengthy and disruptive downtime
One of the signs of the due maintenance is reduced and insufficient airflow. Insufficient airflow greatly reduces the productivity of the system and exponentially drives up the running cost of the system in terms of consumed electricity. For the end-user, it feels like the air conditioning is not working.
Reduced air flow happens because of blocked coils and air filters. People who ate magic mushrooms in college think these filters are to clean the air in the room. People who actually did some study in the college know these filters are a protective device for the air conditioning system. The purpose of the filter is to:
- protect the coil of the indoor unit from getting contaminated with dust particles
- prevent the dust settle and harden on the cooling/heating coil
- prevent the dust entering the drain system
- the fact the filter cleans the air we breathe is a mere side effect of the above
Unfortunately, this method has one major drawback: the filters must be cleaned periodically to restore required airflow for the correct functioning of the air conditioning system.
Maintenance span between various systems will vary depending on the type of the system used, how often the system is used, specific installation conditions and the nature of the site where the system is installed.
Wall type air conditioning maintenance
Wall type air conditioning systems, that are installed on the indoor walls, usually have the air filters located on the top of the unit. To clean the filters stop the system and make your way to the unit. Air filters are located under the top panel. The panel usually clicks on the unit on both sides and no tools should be needed for the job. Open the top panel by slightly pulling the top panel upwards, take care not to snap the panel in half. Once the panel is open you should have full access to the filters and only need to pull the filter out of the slot(s), clean the filters with tap water or hoover and slide back to the slot(s) and click the top panel on. That’s it, you’re done.

Cassette type air conditioner DIY service
Cassette systems are installed on the ceilings and they allow 4-way air distribution and large cooling capacity. The filters of these units are located at the bottom of the unit, hidden behind the fascia panel. The fascia is attached to the unit by two hinges on one side, and by two sliding- or push clips on the opposite side. Push the clips and the panel should click open, gently let fascia fall back and hang on the hinges. On the inside of the fascia, you should see usually black colour filter that snaps into the fascia panel in the four corners, you need to manipulate the filter out of the slot, take extra care because these filters often span during the maintenance and pay attention to which way the filter goes back once cleaned.

Wall & Ceiling type air conditioner DIY service
Wall & ceiling type air conditioners are normally installed on the lower end of the walls or under the ceilings. The filters of these units are located on the side and bottom of the unit respectively and are easy to access for the maintenance purposes. All you need to do is to unclick the filter covers, remove and clean the filters, put them back and click the covers on.
Ducted air con system DIY service
Ducted systems are usually installed in the suspended ceiling void and cold air is distributed to different parts of the room/s via air ducts. At the end of the air duct is a diffuser to distribute the air in all directions. To clean the filters of the ducted air-con system you must first find the indoor unit of the system. The best way to locate the unit is to lift one of the ceiling grid and track the duct back to the unit. 99% chance the unit is somewhere above the suspended ceiling but it also may be in another room or loft of your business. Once you see it, you know you have found it, as its usually a rectangular box to what 2 or more ducts are attached. On the opposite side of the air handling unit there may be a duct/s as well if this is a case this particular installation is designed to work with the fresh air supply.
Depending on the make and model the access to the filter may be located at the back of the unit or on the side of the unit. The filter is fitted in the special groove on the housing of the indoor unit and it may be screwed or clamped down to the housing to hold it firmly in place. All that’s left to do is to unscrew the screws and pull the filter out of the groove. You can hoover or wash the filter with water and fit it back on the unit.
Side loading filter systems: On some systems, the filters are loaded on the unit from the side. The filter would be located behind the side panel that is screwed down. Undo the screws and pull the filter bracket straight out of the unit, remove and clean filter, place the filter back on the bracket and slide the bracket back into the unit and screw down the side panel. Job done.

REPAIR & GASSING
A modern air conditioning system is a versatile and high tech system. It could be a standalone installation or a part of the BMS. Most common systems consist of a single or multiple indoor and outdoor units controlled by a wired or infrared controller for close control. At the heart of the system is a refrigerant that is driven by electrical and mechanical components to achieve high and low temperatures suitable for comfortable cooling and heating. This is why an air con system could also be referred to as a heat pump system.
