Things to Consider Before Buying Whole House Evaporative Coolers

Hope you are enjoyed our top 10 whole house evaporative cooler reviews, time for you to sit down and consider the things to factor in before making that purchase.

First of all, you need to understand that an evaporative cooler is not the same as an air conditioner. Once you have this firmly implanted in your mind, investing in the right evaporative cooler becomes easier.

We’re about to get a bit geeky. But don’t worry, it’s short and easily put. Below are the features you need to look at before buying the device.

Working Principle

As mentioned above, an evaporative cooler is different than an air conditioner. The basic difference lies in how the evaporative cooler actually works. You see, it uses the natural concept of evaporation – warm air touches a cool surface and absorbs the moisture, turning the warm air into cool air.

An evaporative air cooler works similarly. It runs the hot, dry air through moisture-laden pads and turns it into cool air.

The air that the evaporative cooler releases feels like a natural breeze and is up to 20 degrees cooler from outside air. Since there is continuous circulation, your home feels fresh and invigorating, doing away with all the stale and trapped air inside.

Evaporative coolers work good in dry regions where the humidity levels are very low – less than 60%. So, if you’re living somewhere where you tend to have humidity and rains, an evaporative cooler will not work well for you. However, evaporative coolers are used to absorb moisture in outdoor settings like garages and docks.

To prevent moisture from accumulating indoors, you should always leave a door or a window slightly open when using a whole house evaporative cooler.

Types Of Evaporative Coolers

Whole house evaporative coolers come in different types as per different needs. Here’s what you need to know to help you pick the right one.

Portable Evaporative Coolers – These can be carried around easily and work great for smaller spaces. They can cool a room of size 300 square feet. quite easily.

Window Units – These are fitted into a window to cool down an entire house or a single room or even a garage.

Down Discharge – This type of evaporative coolers is installed on the rooftop so that the cool air is pushed down to make the entire house cooler.

Side Discharge – Instead of air pushing down as in down discharge, the side discharge type of evaporative coolers is fitted on the side of a house or a building to discharge cool air from the sides.

Depending on your cooling needs, select any one of the four types mentioned above. If you’re looking to cool down a single room, a portable evaporative cooler is good to go. Otherwise, the other types would be advisable if you want your entire house or office to be cooled.

Types Of Cooling Pads

It’s important to know the type of materials used for the cooling pads in your evaporative cooler. This will affect maintenance and cost directly.

There are basically two types of pads used – fiber pads and rigid media pads.

Fiber Pads cost lower but need more maintenance. Chances are you’ll need to replace the fiber pads often. These are made from cellulose or synthetic fiber and are good for evaporative coolers that have cooling inlets from many sides. They are usually 1 to 2 inches thick.

On the other hand, Rigid Media Pads are more expensive but require low maintenance and are long-lasting. These are made from corrugated sheets and work better for evaporative coolers with single inlets.

These are better at keeping the room cooler for longer, mainly because of their thickness – which is 8 to 12 inches.

Ease Of Installation And Use

There are two ways to install an evaporative air cooler – either it’s on the rooftop or it’s mounted on the wall.

While a rooftop installation is more expensive and has the chances of a roof leak, it will, nonetheless, be more effective in cooling your entire home.

A wall mounted evaporative cooler is easier to maintain and more convenient.

Please note that a rooftop installation charge will depend on the region and the structure of your home.

Overall, both installation types are centralized to ensure that your entire home is evenly cooled. However, a more central-location installation is good for compact homes while using a duct system makes sure that all the rooms and passageways of a larger house are getting cool properly.

CFM Ratings

CFM or cubic feet per minute is the unit of measurement for how fast an evaporative air cooler efficiently cools a given space. This is an indication of the strength of the air flow.

Evaporative coolers for home use usually measure between 3,000 to 8,500 CFM, whereas a larger than average home would better with a CFM of 7,000 or more.

There’s only one way to make sure that your evaporative air cooler is functioning at its optimum CFM – regular maintenance.

Provided Accessories

Your evaporative home cooler may come with accessories like a purge pump or a ceiling vent.

A purge pump will raise the cost of the unit, but it is a good thing to have as it will automatically drain water every 6 – 8 hours, preventing mineral build-up and thus, making the whole unit last longer.

If you’re worried about keeping your doors and windows open, a ceiling vent will let you have peace of mind. The warm air is pushed out through this ceiling vent and you need not be on watch if someone was creeping into your home through your open door or window!


Once again, depending on your cooling needs, you have to decide on the size of an evaporative cooler.

A portable cooler is good if you want a single room or a small space to be cooled. On the other hand, investing in a big evaporative cooler for a small home would be a waste of money and energy as it would work over its optimum capacity.

For an accurate estimation of what size of an evaporative cooler you need, you simply have to divide your living space by 2 to arrive at the CFM you need.

For example, if your home is 1200 square feet. with 8-foot ceilings, all you need to do is 1200 X 8/2 = 4,800 CFM. So, you need an evaporative cooler with at least 4,800 CFM to cool your space,

Simple, isn’t it?

What Are The Benefits Of Using An Evaporative Cooler In Your Home?

How To Take Care Your Evaporative Cooler For Longevity?

The maintenance of an evaporative cooler is simple and easy. Cleaning both the exterior and the interior can extend its life and you can reap the benefits for a long time.

You must take care of three fundamental things for proper maintenance – basic cleaning, proper storage, and shutdown when not in use.

1. Basic Cleaning

It’s good to check the filter, pump, water tank, and pads once a month. If you use your portable evaporative cooler for long periods of time, it’s recommended you clean the evaporative media and water curtains every fortnight with clean, lukewarm water and some detergent.

This will get rid of all the dust and dirt trapped in the filter. Besides, you might have to replace the pads every month if the cooler is in continuous use.

2. Cleaning Before Storage

The exterior part of the portable cooler should also be cleaned regularly with a damp cloth. When you are putting it away for the season, make sure to drain the water tank and clean the filter. Before packing it away, turn it on in the fan mode for half an hour to an hour so that the unit is completely dry.

When it comes to wall-mounted evaporative coolers, you need to prep it for spring and summertime use and once again, when you put it away for winter.

Before you start using it in season, clean the moisture pads and the pump to ensure these are completely ready to function.

3. Disassemble When Not In Use

Once you’re ready to put it away, check the water supply connection and disconnect it. Drain the water tank completely. Put a cover on the cooler to keep it dust-free and unplug the power cable. Make sure the evaporative media is absolutely dry and is not prone to mildew.

Remember to disconnect the unit from the power connection before you start the cleaning process.

Frequently Asked Questions (FAQ)

1. Does Evaporative Cooling Really Work?

Answer: Yes, evaporative cooling is a natural way of cooling down the interior of a home or other larger space. It effectively reduces the temperature by as much as about 20 degrees than outside temperatures.

2. How Does Evaporative Cooling Work?

6. What is CFM?

Answer: CFM or cubic feet per minute measures how fast your evaporative cooler can bring down the temperatures in each square feet of space. It shows the strength of the airflow.

9. What’s The Difference Between An Evaporative Cooler And An Air Conditioner?

Answer: An evaporative cooler uses the natural phenomenon of evaporation to cool a room, using only a fan, water, and cooling pads. An air conditioner, however, uses refrigerants and a compressor, much like a refrigerator, to make the room cool.

10. What’s The Right Way To Clean An Evaporative Cooler?
