Top Reasons to Replace Your Evaporative Cooler

Posted on: 29 May 2015

Have you recently moved into an older home that has a swamp cooler and not a central air conditioner? Are you wondering whether you should keep the home the way it is or whether you should install an air conditioner? Here are some reasons why installing a central air conditioner might be right for you:

Evaporative cooling doesn't work if it's too hot

An evaporative cooler is great if you live in a relatively dry but mild area. But if it gets extremely hot where you live, an evaporative cooler may not work as well as you might be expecting. An evaporative cooler typically only makes the air inside five to fifteen degrees cooler than the air outside your home. When the temperature is in the triple digits outside, this might not feel like much at all.  In contrast, a central air conditioner works no matter what the outside temperature is. 

Evaporative coolers could cause mold or mildew problems indoors

An evaporative cooler works by raising the moisture content of the air, creating a cooling effect. If this raises the humidity in your home above 60%, you could start to have mold or mildew issues. While you may not see anything wrong with a spot of mold here or there, mold can have a serious effect on the health of you and your family. Fortunately, a central air conditioner doesn't need to raise the humidity in the air in order to make it cooler inside. In addition, should you already live in a humid climate, you can even purchase an air conditioner that has a dehumidifier to remove moisture from the air and make it more comfortable inside.

Evaporative cooler use could make you a burglary target

Evaporative coolers work best when you leave windows and doors slightly ajar, in order to allow warmer air to escape your home. If you keep your windows and doors tightly closed, an evaporative cooler either won't work or won't work as well. Unfortunately, these open windows could be an invitation for a burglar to enter your home while you're sleeping. If this is a concern for you, a central air conditioner works best when all the doors and windows are kept tightly shut. A central air conditioner recycles air within the home, rather than drawing in air from the outside. 

Even if you decide to keep your evaporative cooler for whatever reason, you should consider adding a central air conditioning unit to your home as well. By doing this, you'll be able to partially offset the disadvantages of one system by the use of the other.
