Yearly servicing of your Evaporative air conditioner is very important if you want to keep it running in optimal condition. Usually an air conditioner service trades person will come around and do it for you, but with a bit of knowledge you can do it too and save some money and maybe even do a better job.
An Evaporative Air conditioner is a very simple appliance but needs regular care and maintenance. It draws in hot air through wet filter pads and in turn cools the air to be blown through out your home. They don’t work so well when its humid, but for hot dry weather they are a fantastic cheap source of cool air for your house.
To service your Evaporative air conditioner you will need the following items.
- Water hose and trigger sprayer
- Small Paint brush
- Screw Driver
- Air Conditioner Remote (If it is wireless)
- Disinfectant in a spray bottle
Safety: Please take care on Working at Heights and wear a harness. Always hold on and have good gripping footwear.
Evaporative Cooler Service Removing Filter Pads:
You first need to remove all the pads off your unit and take them down to the ground level for washing or replacement.
This is usually done by removing the clips on each side of the evap panel.

Evaporative Air-conditioner Pads:
Every Evaporative air conditioner will have a different way of removing the filer pad frames. On this Breezair Icon unit you just use a screwdriver to lever off the clips.
There are two kinds of evaporative filter pads.
- The first is the celdek pad. This is made from a corrugated paper with a binder. It holds its shape well and has good air flow. Newer evaporative coolers use this type of filter pad.
- Aspen Woodwool Filter Pad. Thinks of wood shavings thats been conditioned for wet water use bound together to make a filter pad. It needs to be fluffed up to stop the pad restricting air flow.
Evaporative cooler maintenance Service:
When all the Filter pad frames are removed and taken down to ground level, you will be able to get good access to start servicing the unit.
This particular Evaporative unit has a blocked drain so the cooling water was getting old and dirty. The drain had to be unblocked before continuing with the service
Evaporator Clean out all dirt:
Use a paint brush to brush out all loose scale and dirt. Once this is done you can use a hose to flush out more dirt down to the drain. You will have to do this a few times to get a clean system. If you have a lot of scale you may have to use a scrubbing-brush, water can help.
Air conditioner Flush out system:
You will have to run the system a few times to have clean water in the base. Usually do this with the filter pads on to flush the pads as well. Run for 10 minutes then press drain to empty the reservoir.
How to clean air cooler pads – Breezair Pads:
Take the Evaporate air conditioner pads down to ground level and hose out. Once dry bring them back up and reinstall. I like to spray the pads with disinfectant to clean out any bacteria that may be present. Wash it all through well. You will get that disinfectant smell for a day when you first start you system but goes away very quickly.
Box Up Air-conditioner:
After you have finished all the cleaning replace the filter pads and turn on the evaporation air-conditioner. Press dump on your controller a few times during the day. This will dump all the water and flush out any cleaning residue that may have been left. You can run a hose from your drain to your garden, to help reuse the water and grow those graft trees we done the other month.
Winter Service and Power Down
Once winter comes along there are a few basic steps to take. Turn off all power to the unit and drain the unit. Turn off the water supply. If you have a cover now is a good time to put the cover over the unit and box it all up. This stops the heat from escaping through the air-conditioner.
Low power consumption evaporative air conditioner
Breezair icon is one of the lowest power consumption evaporative air-conditioners in the world. They work extremely well in dry hot parts of the world. Their main design is that the motor and the fan are all made as one unit.
The fan is a dual drum type that is very efficient. The motor is variable speed that means no V-Belts to break. Also know as Direct drive inverter. With a Variable Range of 170 to 556 RPM.
The cooling pads are Chillcel™ which should last the life of the cooler if properly serviced.
How much electricity does an evaporative air conditioner use
Not much compared to a refrigerate air conditioner. As you can see on the graph below you could save nearly $350 dollars in electricity running costs.
These figures take into account running the air con for around 300 hours a year at about 29c kwh.
Depending on the size of the cooler you may only be pulling about 5 amps or less. Its better to over size your evaporative cooler so you can runn it at a slower speed to save power.
These is a small amount of water running cost but that will only be a few dollars each year.
Thats it enjoy many years of cheap service.
