Maximizing Your Cooling System: Tips for Evaporative Cooling Performance


If you’re using an evaporative cooling system to keep your home cool, you want it to be working at its maximum efficiency. A dirty indoor coil and blocked vents are just two factors that can inhibit your air conditioner’s performance. Find out more about how to make sure your evaporative cooling system runs smoothly by following these tips:

Maximize Indoor Airflow

To maximize the performance of your evaporative cooling system, there are a few things you can do to help it run efficiently. First and foremost, make sure that your indoor coil is clean and free from debris. Debris buildup on coils can reduce airflow and lead to poor performance or even damage (which would require expensive repairs).

Secondly, ensure that proper airflow exists in the house during periods of use–this means opening windows as needed and making sure there aren’t any leaks in the ductwork or attic spaces. An improperly sealed home will cause hot air to leak out through cracks in walls or ceilings instead of being cooled by an evaporative cooler.

Make Sure Your Outdoor Coil Is Clean

To ensure your outdoor coil is as clean as possible, you’ll want to clean it at least once a month. This will help keep the system running efficiently and effectively.

It’s easy to tell if your outdoor coil needs cleaning: look for black or brown spots on it. If you see these, then that means dirt has accumulated on top of your evaporative cooling system’s condenser (the component responsible for cooling).

If there are no visible signs of dirt accumulation, then consider using a garden hose with warm water pressure and mild soap (like dishwashing liquid) to wash away any dust or grime that has collected on top of this component over time.

Fix Leaks and Poor Insulation

The first thing you should do is make sure your home is tight and well-insulated. This isn’t just an issue with evaporative cooling systems; it’s also essential for air conditioning. If you have poor insulation or leaks in your home, you’ll waste energy and money on both heating and cooling.

The easiest way to check for leaks is to use a moisture meter (or “moisture tester”) like this one from Amazon. Simply plug it into any outlet, then wave it around the outside walls of your house until it lights up. If there are any moist areas where there shouldn’t be any moisture at all (like inside walls), those are likely places where water has gotten into the wall cavity from outside sources (such as rainwater runoff or sprinkler systems running too long during rainy seasons), which means they need fixing before installing an evaporative cooling system!

Monitor Temperatures

You should monitor both indoor and outdoor temperatures. The temperature difference between the two is your evaporative cooling system’s ability to cool.

The simplest way is to use a thermometer, but there are also more precise ways to measure temperature. If you have access to a digital indoor or outdoor thermometer with a hygrometer (humidity), this will give you accurate readings of both indoor and outdoor conditions. You can also buy an inexpensive weather station that will provide all of this information in one compact package–and some even come with wireless capabilities so they can be placed anywhere in your home or office!

Sealing Up Holes in the Attic or Crawlspace

Sealing up holes in the attic or crawlspace is a good idea for more reasons than one. Not only will it help keep your home cool, but it can also prevent pests from getting inside.

Once you’ve sealed up all of those pesky little cracks and gaps, make sure to check out our guide on how to maximize your cooling system: Tips for Evaporative Cooling Performance!

You can maximize your evaporative cooling by making sure you have a clean indoor coil, a working HVAC system, and that your attic or crawlspace vents aren’t leaking.

The most important thing to remember when trying to get the most out of your evaporative cooling system is that it’s not just about whether or not you have an evaporative cooler in place – it’s also about how well-maintained that unit is. If there are leaks in the ductwork and poor insulation on windows and doors, then chances are good that some of the moisture being pulled out by the air exchange will return inside again before it has time to cool down!


Now that you know the ins and outs of evaporative cooling, it’s time to get started on your system! If you have questions about where to start or what kind of equipment would work best for your home, give us a call today.
