Your evaporative cooler is one of the best investments for your home that you could make. As such, it would be wise to ensure that it serves you as it was intended for as long as possible. 

This is where regular evaporative cooler maintenance comes in.

By ensuring that your evaporative cooling unit is checked, cleaned, and tweaked as necessary, it will work optimally for longer. This will also make sure that you will get your money’s worth and keep your investment in its prime. 

With that said, if you still need some convincing that your unit needs regular maintenance, here are a few things for you to ponder.

Ensure Peak Efficiency

By its nature, an evaporative cooler is one of the most efficient cooling systems around. It uses up a lot less energy compared to other types of climate control systems. This can only be good for your electricity bill.

As with any kind of machine, however, evaporative coolers do start to deteriorate with constant use. They become a lot less smooth when operating, which then leads to efficiency issues.


After a while, they can take a bit longer to provide the cooling effect that they are meant to. This means that in order to enjoy their features, you would need to keep them on for longer. That then uses up more power. 

When you allow your evaporative cooler to continue to operate without regular maintenance, the more severe the problem becomes. Eventually, it won’t be the efficient cooling unit that you bought, in the beginning.

The resulting increase in your electricity bill might not be that big for each instance, but the costs can stack up. When paired with all of the other issues that come with non-maintenance, you might be looking at a pretty hefty expense.

Maximum Cooling Effect

The whole point of getting an evaporative cooler is to keep your home cool and fresh. At the start, this is exactly what you are going to get, especially if you know how to make the most of your unit.

However, this won’t be the case forever if you don’t give your evaporative cooler some TLC. At some point, the parts are going to start slowing down and no longer work as well as they used to.

This then translates to issues with the actual functioning of the unit, which is to lower the temperature of the room. After some time, the machine will start to strain just so it can produce the cooling effect that you want.

Even then, it might no longer be able to cool a room to the same level of comfort that you are used to. 

These all point to the need for regular maintenance.

Now, it’s worth noting that your evaporative cooler will eventually become too old and will need to be replaced. However, you want to delay that for as long as possible so that you don’t waste so much money buying new units every few years or so.

Longer Lasting

As already noted, evaporative coolers will start breaking down after you have been using them for some time. This will eventually make them too old to use, but you can be the one to decide when this will be.

Through regular maintenance, you can ensure that your unit will continue to work for years. This will not only save you money, but it will also spare you from the hassle of shopping for a new one.

More to the point, you will have more money to spend on other things if you don’t keep on spending them on new evaporative coolers. You might even profit from your old one by either selling it or giving it to someone else.

Health and Safety

Climate control systems are neat and they can be incredibly useful in areas where temperatures can get particularly hot. With that said, if they are not properly cleaned or maintained, they can also be a health hazard.


Granted, this issue is more prevalent among air conditioning units than they are evaporative coolers. However, there is still that risk. As such, you might want to make sure that you don’t start breathing in contaminants. 

Regularly maintaining your unit will fix this problem.

If you are not familiar with or don’t have a lot of time to understand exactly what goes into an evaporative cooler, this issue becomes even more important. Having your unit looked at by a professional will alert you if there are any moulds that have formed in the internal parts, for example.

No Funky Smells

Then we come to the matter of odour, which is not that big of a deal but would still be quite unpleasant. Evaporative coolers might also be known as swamp coolers, but that doesn’t mean they should smell like one.

This can sometimes happen for several reasons, but the biggest would definitely be the lack of maintenance. Units that are only used for certain seasons would be particularly susceptible if they are not stored correctly.

By having your evaporative cooler regularly maintained and cleaned, this will never be a problem. The maintenance and cleaning personnel will also be able to provide you with more details about how you can prevent bad odour from ever being a problem.


If you want your evaporative cooler to stick around for a long time and to provide you with its sweet, cooling effect at optimal levels, then maintenance is a must. It must be regular, scheduled, and professional. Otherwise, you would be wasting money in more ways than one.

You have to remember that as great as evaporative coolers might be, they are just machines. They need to be looked at, cleaned, tinkered with, and adjusted as necessary. This is especially important for those who don’t have any mechanical expertise. Even something as simple as changing the cooling pad can be overlooked. So don’t take it for granted.
