DIY Tips On Evaporative Cooler Installation

Evaporative coolers are a great home cooling option, especially if you come from an area where it’s fairly dry and it’s the hot season. Of course, there are multiple benefits in choosing an evaporative cooler for your home cooling. According to Roy Otterbein, the president of a Phoenix, Arizona-based Company, Otterbein Engineering, an evaporative cooler is one tenth to a quarter cheaper in terms of operational costs compared to air conditioning units.

The installation of a swamp cooler can prove to be a fairly difficult task, even to the best handyman around. One of the main reasons is mainly because the coolers are not as light as you may think, they can be pretty heavy. However, this doesn’t necessarily mean that DIY installation is impossible. The only simple requirement is that you follow the steps and have a friend help you with the heavy lifting. Below are some DIY evaporative cooler installation tips you might want to check out.

NUMBER 1 –  The Support Assembly

One of the advantages of an evaporative cooler is that they come with a support assembly that is ready to use. If by chance you don’t have one, you can readily purchase one from the stores and ensure that it is of the right size for your swamp cooler. Be sure to read the manual carefully and make sure that when building the support assembly outside the window sill, you ensure that it is as firm as possible.

NUMBER 2 –  Mounting the Cooler

This stage involves placing the unit in its resting position, for which you may need a set of extra hands since the unit can be fairly heavy to lift. Carefully lift and mount the cooler on the support assembly. One of you should hold the cooler on the support mounting firmly while the other one is attaching the wall hangers and the brackets to the cooler. Have the manual close to ensure that you don’t miss on any detail.

NUMBER 3 – The Water Line

Your cooler requires a steady supply of clean water. Connect the water line to the cooler from your outside water source and make sure you have a cut off valve. The cutoff valve will be highly useful, especially when it’s time to drain the system, which will be required during the start of a winter season to minimize any form of damage from the harsh weather.

NUMBER 4 –  Installing the Air Vent

You should be provided with an air vent cover and this should be in the evaporative cooler kit. You need to now attach the air cover. The air vent is what directs the cool air into your house. Roof tar is best in sealing off any opening. Conversely, the screws used on the mounting brackets should also be coated to avoid rusting.

NUMBER 5 –  Power Up

Ensure that the power outlet is grounded 120-V before you plug in the cooler. Before you power up your equipment, ensure there are no leaks. Also, fill any void space around the cooler so that you don’t lose the cooled air from the cooler. If all this checks out, you are good to go. If you are unfamiliar with electrical connections, is good to have the help of a certified electrician.

As much as these DIY tips can help you set the equipment up and running, it is always much wiser to leave the job to the evaporative cooler installation experts.

How Environmentally Friendly Are Evaporative Coolers?

It is now evident that more and more homeowners are more knowledgeable about the issues concerning our environment. Lots of deliberations have been ongoing globally on the ways we can all improve and care for our environment to better our lives. This being the case, the evaporative coolers have been found to offer safer and smarter ways of improving on energy efficiency. The use of water as a means of cooling used in the evaporative coolers increases efficiency. As we all know, water has the best thermodynamic and chemical properties. On issues energy, evaporative coolers use less electricity and can save up to 75% of your energy bills. Additionally, evaporative coolers are less associated with the emission of hazardous chemicals and gasses that degrade the environment. But just how environmentally friendly are evaporative coolers? Below are some key points to just pointing out how friendly the evaporative coolers are to the environment.

1. Evaporative Coolers Don’t Use HCFCs

HCFC or Hydrochlorofluorocarbons, one of the longest words in the chemical dictionary; has been rated Class II as one of the ozone-depleting substances. HCFCs are used in the following applications, the making of aerosols, fire extinguishers, foam blowing, solvents, refrigeration, and air conditioning. The history of HCFCs dates back to the 90s having being introduced as an alternative chemical for CFC.

The Montreal Protocol added HCFC to their list of controlled substances. It is shocking to learn that the production of HCFC was 34,400ODP (Ozone Depleting Potential) tons in 2006. Shocking enough, 75% of HCFC is used in air conditioning and in the refrigeration sectors. HCFC have up to 2000-times higher levels of global warming potential than that of carbon dioxide. Evaporative coolers, on the other hand, will only use water as a means to cool your living room.

2. Swamp Coolers, Global Warming and Energy Conservation

One of the most common types of greenhouse gasses that affect our atmosphere is carbon dioxide. The generation of electricity and power stations contribute immensely to the carbon dioxide emission in the atmosphere. Energy conservation from our appliance would mean less carbon monoxide in our atmosphere, which is a nongreenhouse gas.


In addition to the fact that they don’t emit harmful gasses into the atmosphere, evaporative coolers use less electricity, making them even more environmentally friendly.

3. Humidification

Unlike air conditioners, they do not remove moisture from the air. Evaporative coolers increase the humidity levels in dry air, meaning that they can be more convenient cooling alternatives in the hotter, dryer regions of the world.


4. Evaporative Coolers Provide Fresher Air

Homeowners who choose evaporative cooler installation over central air conditioning ensure themselves that they are breathing only fresh air with the provision of having sufficient ventilation. You can open your doors and windows to free up the used up air without the worries of losing air flow. You will never have to breathe in recirculated air and you can worry less about stale air.



From the pointers above, we can safely conclude that evaporative cooling is a good choice for the environmentally conscious consumer as evaporative coolers do not use chemicals of any kind. The use of water, the simplest form of technology as a natural source for cooling the air, is a sure enough, reason why the evaporative coolers would be attributed to being environmentally friendly.

Quiet Please – Evaporative Cooler or Air Conditioner?

A noisy air conditioner, irrespective of the make or model, can prove to be a nuisance. It can create serious problems especially between neighbors and the owner can have it rough especially in cities and towns where strict measures of noise pollution have been put in place. The main focus of this piece is to shed more light on the issue of noise pollution in air conditioners and evaporative coolers. It is going to be of much use in helping you make the right choice of air cooling equipment.

The main objective of owning either an evaporative cooler or an air conditioner is for your comfort benefits. It would, therefore, be unjust when the item meant to give you comfort becomes an irritant to your neighbors, or to you. In general, the level of noise production in HVAC units depends on various factors such as type, size, and capacity. Depending on the make, some cooling units are quieter than others. But then again, noise is one of the crucial factors to consider when opting between a swamp cooler and an air conditioner. So which is quieter-evaporative cooler or air conditioner?


Evaporative coolers basically use the evaporation principle to cool your indoor air [2]. Among others such as energy efficiency, fresh air production, humidification, affordability, and operational cost-effectiveness, quiet operation is one of the major benefits of evaporative coolers. During operation, the axial fan, a feature in many evaporative coolers, moves air in a circular motion inside the ducts. This may produce some level of turbulent noises in the ducts. The quieter type of evaporative coolers has a centrifugal fan that tends to move the air in a straight line inside the vents so be wise when choosing your evaporative cooler.


Sound Power: Be it an evaporative cooler or the air conditioner, Sound Power (LW) of the unit itself is what determines the noise from the unit. The lower the LW number on the sticker, the quieter the unit will be.

Motor Location: In addition, the location of the motor also is another crucial factor that determines whether the unit is quiet or not. In air conditioning, the split type of AC has the best placement of the motor. The split system unit with an inverter is a quieter type of air conditioning unit and is also more energy efficient. The inverter will slow down the speed while ensuring that the desired temperature is maintained.

The Size Factor: Choosing the right size of the unit, whether installing an evaporative cooler or central air conditioner is also another determinant factor when it comes to the noise produced by your cooling system. A small air conditioner in a larger room will end up getting overworked and the results will be an inefficiency, causing it to be noisy.

Design and Placement: When designing or renovating your house, it will prove helpful to ensure that the walls are well insulated and that your cooling unit is positioned right, during installation. One of the best ways to position the unit is placing it at or on the rear wall, ensuring that the air conditioner is facing the backyard. You can also position the air conditioner facing the streets. If the noise is in excess, it would be advisable to construct a barrier that will shield your neighbors from the noise.

At this point, however, it can be safe to conclude that evaporative coolers are generally quieter, basically because of the fact that they have motors and the water pumps that are fairly smaller compared to conventional ACs. Swamp coolers also don’t use a lot of energy. However, to be on the safe side, it’s always advisable that consumers check the noise level of the cooling unit before purchasing or having it installed by a professional evaporative cooling installation contractor.

How Does An Evaporative Cooler Do Its Job?

Also known as swamp cooler, wet air cooler, or sometimes a desert cooler, the evaporative cooler is slowly becoming a popular alternative to conventional home-cooling methods such as air conditioners due to various reasons, including energy efficiency. As the name suggests, this is a device that cools air through the means of evaporation. Evaporative coolers have been proven to provide efficient cooling, especially in hot dry conditions rather than in humid conditions. This is because the system relies on evaporating the moisture from the wet filter pads to provide the cooling effect needed.

In this article on how does an evaporative cooler work? We are going to tackle one key factor that is mainly exploited, enthalpy of vaporization, which can be described as the amount of energy required to transform a liquid substance into gas. In this case, water is basically our liquid substance.

Simple Mechanical Principles

The human body is a classic best example when it comes to explaining how evaporative cooling works. The moisture on our skin surface, also known as perspiration, once into contact with the air, evaporates leaving us with a cool sensation. It is this process of evaporation that cools the skin hence lowering our body temperatures.

In evaporative coolers, a fan inside the unit is used to draw the outside air and passes it through a set of wet filter pads. When hot air passes through these wet filter pads, impurities are removed and the air cooled. After the hot air has been cooled, the wet filter pads retain the warmth. The warm water inside the filter pads trickles down and is replaced by cool water pumped to the top of the pads, in a continuous cycle. A tank at the base of the unit contains the required amount of water needed to ensure this cycle goes on.

Before proceeding with evaporative cooler installation, make sure ample ventilation is necessary because the cool air is not re-circulated in the building. This means that you may need to open your doors or windows to allow the already the indoor air to escape the building. However, for security reasons, installation of up ducts with the provision of attic ventilation is necessary to ensure that warm air is exhausted into the attic as cool air comes in from the evaporative cooler.

Maximizing on Performance

Setting the correct number of window openings is paramount as far as performance is concerned. Once the cool air is blown into the room from the evaporative cooler, it needs to be let out or else fresh air won’t be able to get in. Keeping your windows open or alternatively installing up ducts will be your best option when it comes to getting the best of performance from your evaporative cooler. Basically, you will need 300mm window opening for each and every room, which may vary depending on the room size. Your home’s location matters a lot because the evaporative cooler opening should not face the wind. Proper maintenance is also overly important and you can ensure this by having the cooler serviced at least two times annually.

Proper Sizing

Air flow and the space of the area in need of cooling are the determinant factors that affect the size of evaporative cooler you want to install. Getting the accurate quotation from your retailer and having your installer do some humidity tests are important tasks that need undertaking.
An evaporative cooler not only cools your home, they also add some pleasant moisture in it and will not circulate the air inside over and over but will bring in fresh air from outside, and it is up to you to ensure the necessary ventilation.
