The pros and cons of evaporative coolers also known as swamp coolers.
I don’t know about you but I thought my title was ‘cool’. Hehe
Since we have been successfully installing and servicing these units in Albuquerque and surrounding areas for more than 40 years, we thought an article about the differences might help. We will also provide some tips on these systems to help you get the most cooling you can!
Pros and Cons of Evaporative Coolers vs Air Conditioning Units
Costs. Air conditioning costs are typically twice that of evaporative coolers. But- this is only true when humidity is low. During high humidity (rainy) season when combined with higher temps, swamp coolers lose effectiveness. That is when air conditioning is worth the extra costs!
Pros or advantages to Evaporative Cooling Systems
1. Evaporative cooling equipment has lower up-front costs than AC units. Compressors, piping and gas under pressure are expensive!
2. It costs less to operate an evaporative cooler than an AC unit. Obviously an AC unit compressor takes a lot of power to compress and force the gas around the system.
3. Coolers are simple to install. No ductworks, thermostats, outside and inside units etc.
Cons or disadvantages to Evaporative Cooling Systems
1. You have much less control over air temperature. Swamp coolers cool based on air temperature, humidity level and water temperature. AC units can be set to maintain a temperature.
2. Because air is not passed through filters, evaporative cooler air is not cleaned as well as with an air conditioner.
3. Windows (or some other form of air venting) are a part of evaporative cooling where AC units simply recondition internal air. External air can be the cause for more airborne dirt, pollen and humidity. Damp air can actually cause wood furniture and doors to swell in high humidity!
4. Swamp coolers require more maintenance.
THere you go. Hope that helps you make a decision if you have that decision to make! Now let’s look at some tips for getting the most out of your cooler.
Tips for Evaporative Coolers
1. Do not run an evaporative cooling system at the same time you run an air conditioner. They will work against each other!
2. Do not open a window or door when running an air conditioner as the unit will have to work harder!
3. Maintain whatever kind of unit you have for longevity, peak performance and cost savings.
