Evaporative cooling preventative maintenance

eco friendly evaporative cooling pads

Those who have made the switch to evaporative cooling systems are well aware of the energy savings that they get each and every day. If you have not heard about this type of ducted air conditioning, allow us to bring you up to speed before getting to the part about properly maintaining the system.

An evaporative system uses water to add more effective cooling to a space, using less energy in the process. Water is essentially spayed onto filter pads which the air has to pass through on the way to the space that is being cooled. To get an idea of how this works, take a moment to blow on your hand. Now, wet that same hand and blow again and you will feel a cooling sensation on the wet part.

Evaporative air conditioning

As you may have already guesses, those people who use evaporative air conditioning see a significant drop in their monthly energy bills, but that will only last as long as the system is being properly maintained. Evaporative filters are no different than those used in traditional heating and cooling systems in that they have to be replaced when their usefulness is no longer where it should be. If a filter pad starts to become ineffective, the savings that you would normally experience will start to drop.

One of the first things to be on the lookout for is the amount of cool air that is being dispensed by the ducted ac system. If it does not appear to be as cool as it usually is on your current setting, the system may be struggling to keep up. This is a sure sign that maintenance is required, and that is when you should call in the pros. There are some things that you can look for, such as algae and mold growth in the water cells, but there are other things that only an evaporative cooling system pro would be able to spot.

Excelsior filter pads

The best way to ensure that your system runs at peak capacity is to set up a regular maintenance schedule with the installer. By doing this, you can essentially take care of potentially expensive repairs before they ever hit. This is also something that you should do if you are using Excelsior filter pads in your evaporative cooling system, as these have to be replaced annually, no matter how good they may appear to be. These filter pads are the cream of the crop, and they will deliver the most effective cooling, but only if properly maintained.


If you are in the market for an evaporative cooling system, be sure to ask your installer what type of maintenance services they offer after your system is in place. If they do not have a service program in place look for someone else. It is always best if the people who install your system also maintain it, as they will know all of the ins and outs of your system, as well as its history in your building.
