Evaporative Cooling Reviews
The Truth About Evaporative Coolers | Buying a Swamp Cooler

Buying a swamp cooler?
Don’t do it! You might think so if you have ever read any of the many online reviews of swamp coolers. Some of them are quite negative. They say they don’t work well or even at all. Others claim that swamp coolers are not worth the money because they will only cost you $100.00 and then some.
But why would anyone pay such a high price for something that won’t work properly?
I’m going to tell you why these reviewers are wrong, but first let me explain what I mean by “working properly.” When you buy a swamp cooler, it doesn’t just sit there collecting heat. It actually converts that heat into useful energy. That’s why it works. So when someone says that a swamp cooler isn’t working properly, they’re really saying that their unit is inefficient. And while efficiency may be good for your car, it’s not necessarily good for your home or business!
Now, before we get to the root of this problem, let’s first talk about how a swamp cooler works.
Have you ever been in a room where someone has a window unit air conditioner?
If so, then you’ve probably noticed that when it is on high, cool air blows out of the front, but quite warm air blows out of the back. This is because the cool air being pushed out has to pass over all that hot stuff coming out the back. The same concept applies to a swamp cooler, and that’s where the name comes from. A swamp cooler uses water evaporation to provide “free” cooling with no electricity needed!
When used properly, a swamp cooler pushes air through wet pads which cause the air temperature within the house to drop substantially. But, if you don’t use them properly, the only thing you’ll get is warm, wet air blowing into your home.
If you don’t believe me, then just look online at some of the negative reviews. People complain about this all the time!
But swamp coolers really can be great because they are energy-efficient and relatively inexpensive to operate. The problem is that many people have never used one before so they don’t know how they work.
And a lot of these online reviews are from people who don’t know either. I’m here to help. If you just follow my three simple rules, you’ll be fine:
Make sure there is a steady supply of water available so the pads can stay moist. If you don’t have a pool or pond handy, you can use a garden hose connection or even a simple bucket of water will do in a bind.
Always connect the swamp cooler directly into your house’s return-air duct system. Otherwise, the cool air won’t be able to get inside. Also, make sure you close the duct off behind it, otherwise outside air will leak in. Make sure there is proper insulation in the areas where the ducts enter and leave the house.
Following these simple guidelines, you’ll be able to use your swamp cooler all summer long and save some money while doing it. Just remember: swamp coolers are great, but they only work when people use them properly!

Swamp Cooler Can Save You Money
Swamp coolers are a great way to beat the heat without breaking your budget. They work by pushing air through wet pads which cause the air temperature within the house to drop substantially.
Unlike an air conditioner, however, swamp coolers do not blow cold air. But that doesn’t mean they aren’t effective. You see, the temperature of the air being blown out by a swamp cooler is relatively lukewarm. But the air being sucked in is much, much hotter! This difference makes all the difference in the world on a hot summer day.
Now you may be wondering how a swamp cooler can effectively lower the temperature of a room when the air being blown out is lukewarm at best. To understand this concept, think about how you feel right now.
You are comfortable sitting where you are right now, but if you were to stand up, you would feel a definite, although slight, sense of chill in the air. This is because your body heat is being lost through conduction and convection as the air blows over you. When it comes to cooling down an entire room, this little bit of lost heat adds up really quick.
Another good thing about swamp coolers is they are relatively cheap to run. A common misperception is that they require a lot of water to operate.
While it is true that they do need to be kept wet, you don’t actually have to fill them up like a swimming pool. Rather, all you have to do is keep a funnel full and place it at the top of the cooler. This way, the pads can be kept wet perpetually and no extra costs are incurred.
Finally, swamp coolers are also easy on the environment. Rather than blasting icy air that can cause the temperature in a room to get too cold and cause the furnace to work overtime, swamp coolers provide a nice, gentle breeze.
This helps to naturally balance out the temperature and saves money on the utility bills.
In closing, while swamp coolers may not be right for everyone, they can definitely save you money if you live in an area with blistering summer temperatures. They are a green alternative to traditional air conditioners and may even be more comfortable to sleep with on especially hot nights.

Easy and Effective Dehumidifier Tips
Dehumidifiers are a blessing in the spring and fall when the weather is changeable. They help keep the home comfortable and can even help protect your possessions from damage caused by high humidity.
To get the most out of your dehumidifier, follow these tips.
Turn it to the High Setting
Most dehumidifiers have two settings: low and high. The low setting provides 30 pints of moisture removing whereas the high setting provides 50 pints.
That’s a difference of 20 pints! To put that in perspective, a pint of water is equal to a little more than a litre. So you’re saving almost 2 litres for every 1 that you take out.
