EQUIPMENT NEEDED FOR AIR CONDITIONING MAINTENANCE

Here is a list of equipment required to conduct air conditioning DIY maintenance to a good level of quality:

  • ladders to access the ceiling, wall and ducted air conditioner indoor units
  • blue roll or wet cloth to wipe down the fan blades on the ceiling units
  • a hoover to hoover out all the corners and notches of the air conditioner housing
  • possibly a Phillips screwdriver to unscrew a retainer on the ducted air conditioner unit
  • a digital air thermometer to measure the temperature of the air-on and air-off the air conditioning coil
  • a low-pressure sprayer tool to rinse debris off the indoor and outdoor unit coil

WALL TYPE AIR CONDITIONER MAINTENANCE 

Wall type air conditioning systems are installed on the top end of indoor walls. Filters are located on the top of the unit under the fascia panel. To clean the filters stop the system and make your way to the unit. Fascia 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, 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 MAINTENANCE

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.

CEILING TYPE AIR CONDITIONER MAINTENANCE 

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 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 CONDITIONER MAINTENANCE

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 with 2 or more ducts are attached on one end. On the opposite side of the air handling unit, there may be duct/s as well. In 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.

Sideloading 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 usually fixed with screws. Undo the screws and pull the filter bracket straight out of the unit, remove and clean the filter, place the filter back on the bracket and slide the bracket back into the unit and screw down the side panel. Job done.
