Adjusting the Speeds of Your Whole House Fan

A whole house fan is a large fan that is placed in your attic and is used to pull air through your house from open windows or doors. A properly installed whole house fan is a great alternative to central air-conditioning systems, espeirts of the country where temperatures are not exceedingly high and humidity levels are relatively low. Although whole house fans can help cool your home, having control over the speed of your fan will make using your whole house fan more efficient and affordable.

Controlling the Speed of a Whole House Fan

If you are presently using your whole House fans without a hardware switch, then you are probably wasting a lot of money in electricity and putting undue strain on your whole house fan. The addition of a 2 or 3-speed switch would allow you to run the whole house fan on high to quickly ventilate your home and then switch the fan speed to low to maintain temperatures in your home. Converting to a variable-speed fan will save money on your electric bill while extending the life of the fan You can buy variable-speed fan switch kits at many local home improvement stores.

Average Cost for Running Portable Swamp Coolers

Aside from air conditioners, portable swamp coolers are one of the 2 most common methods of cooling an interior. The difference lies in the way they cool a house or building. An air conditioner uses a refrigerant that was compressed by a motor in transferring heat from the inside of a house to the outside. A swamp cooler on the other hand makes use of a fan to blow air through a pad or mesh that is wet with water in transferring the heat from the air to the water in the pad through evaporation.

Operating Cost

A swamp cooler basically has an operating cost that is the same as that of a desk fan or a fish tank. If you are going to consider everything, having a swamp cooler will allow you to save about a third of what you are going to spend on an air conditioner. This is because an air conditioner usually has 3 motors, sometimes 4, and since its compressor deals with high pressure, it needs more power to operate.

Expenditure Breakdown

If you are going to operate a swamp cooler for 40 hours a month during the summer, it will cost you around 1.50 dollars. That would translate to around 6 dollars for 150 hours yearly expenditure. Breaking it down further to per hour cost, that would only be around 3 to 5 cents per hour.
