Advertising is becoming ever more compelling which can lead to you being sold on something whether you want it or not without even realizing. Knowing what you are getting into before you get into it is the secret of common sense consumerism, so this article may be quite useful to you if you are looking to buy a swamp cooler for your home.
Location and Climate
The single most important fact about swamp coolers, as has already been discussed in this blog, is the location and climate that you live in and whether it is conducive to the best operation of this type of air cooling solution. We hear about so many people who have bought an evaporative air cooler, either a portable unit or a larger installation, when they lived in a hot, humid climate that seriously compromised the effectiveness of the cooler.
A salesman may well beat on about the fact that these cooling units will work best in a hot, dry climate and are capable of reducing the room temperature by as much as 30 degrees. But they will likely gloss over the opposing fact that they will not work so well in hot, humid conditions.
The bottom line is that if your climate is humid, do NOT expect a swamp cooler to be effective!
Another compelling sales pitch much loved by advertisers is to highlight the cost comparison between the two main air cooling systems. It is quite true that evaporative coolers cost a lot less to buy as well as being much cheaper to run than air conditioners, but watch out for sales talk that highlights the gap in cost as being so huge.
It's enough to know that there is a considerable saving especially on power consumption when you choose a swamp cooling unit or system, but remember that any electrical appliance still uses power no matter how much or how little. You will still get an elevated power bill in at the end of the month when you use any kind of air cooling device, so don't be sold on empty promises of huge electricity bill savings.
You will pay far less than you would for a comparable air conditioning setup, for sure. But you will still have to pay for the power used by the swamp cooler!
Portable, Vent Free, Vented or Fixed System?
Don't get confused by the different kinds of system that are available. There is an easy way to remember which is which.
Air conditioners use a heat exchange system which does produce hot exhaust air that must be vented to the outdoors and that includes all kinds of portable unit.
Swamp (evaporative) coolers do not need to be vented as they do not produce hot exhaust air as do air conditioners.
Simple? It may sound so, but you would be surprised at how many people don't know the difference.
Worse still is that there are some people who believe they can run a regular portable air conditioning unit in a room with the vent not connected to the outdoors. These are the ones who sit there complaining their aircon units aren't working because the room is not getting any cooler.
In fact, if you don't vent a portable aircon unit to the outside, the room temperature will actually increase as the hot air creates a net heating effect over the cold air put out by the unit!
This is not a problem for swampies, so they are the only truly ventless portable air coolers. So now you know what you are getting into when you consider choosing your air cooling solution. Make your decisions a good one!
