What To Consider Buying Evaporative Coolers For Garage

Before deciding on which garage evaporative coolers to pick, there are necessary features worth knowing. These we’ve shared below as the best criteria for garage coolers’ choice. 


Although evaporative cooling fans are quite efficient and cost-effective, they are not suitable for all climates. The technology behind their operation is only effective in hot dry climates. Thus if you live in a place with high humidity you will be better off with a different type of cooling unit. Be sure to check the climate in the region you live to be sure an evaporative cooler will work for you or not. 

Size of your garage 

Since garages come in different sizes, you need to get a unit that perfectly matches the size of your garage. A model that is too small will have to work extra hard to cool your garage space. Consequently, this will reduce its energy efficiency. On the other hand, a unit that is bigger than required will also be a waste of precious energy.

Before you purchase an evaporative water heater you must measure the size of your garage and ensure that your unit is sized to match it. You will need to calculate the volume of your garage space and determine the number of air exchanges that will cool the room effectively. Most manufacturers air exchange charts on their website that you can check. 

Type of cooler 

Evaporative coolers are of two main types. The residential coolers as the name implies are built specifically for small residential spaces. They are portable units that can be placed on desks, bedside tables, countertops, and so on. Hence they are more suited for spot cooling.

The larger heavy-duty industrial models are suitable for cooling larger spaces such as large garages, workshops, decks, patios, and so on. If you are looking for something that solves localized cooling needs a residential cooler should work great for you. Similarly, industrial models give wider coverage. 

Type of cooling pad 

This is one of the major components that determine how your cooler works and its effectiveness. The cooling pad will also have an impact on the air humidity. There are two types of cooling pads each with different features: 

  • Aspen cooling pads: units with Aspen cooling fans are generally more affordable since they are easier to install and replace in case of damages. They are also more effective. Aspen cooling pads are bio-degradable which means they are not the most durable option. But it is a more environmentally friendly option. 
  • Cellulose or honeycomb cooling pads: these pads are made from synthetic products and resemble a honeycomb hence the name. They are thicker than the Aspen pads which makes them more durable. Coolers with cellulose coolers require minimal maintenance although they might also cost slightly higher. 
  • Be sure to check both options to find the one that suits you best before you make a purchase. 

Check the water tank

The size of a cooler’s water tank will have a major impact on how efficient the unit will be. A larger tank is also more convenient since it means you will not have to refill the unit often. Additionally, some coolers have features in their water tanks that make them more desirable than others. 

For example, some models come with a hose connector that allows you to connect the tank to a water source directly for more continuous usage. Some also have water level indicators or alarms that let you know when the water level becomes too low. You should also check to see the water inlet and drain valve as this will determine how easy the process of filling the unit will be. Some coolers also have units that are removable for easy cleaning and maintenance.
