Do Your Home’s Ventilating Fans Work to Your Advantage?

Published on: August 23, 2012

If you have ventilation fans at your home, you have an opportunity for extremely efficient method of conditioning your indoor air without spending a great deal of money. Your indoor air quality (IAQ) is contingent upon the circulation of air inside of your living space, but the more that you rely solely on your air conditioning unit in order to do this, the more likely it is that you will spend a great deal of money on AC repair from breakdowns and high heating/cooling bills every month.

Trying to have your IAQ on a high standard does not have to bankrupt you. One way that you can save a great deal of money is to use your ventilation fans to your advantage. All you have to do is understand a few basics about the physics of air and heat and you will be well on your way to saving money with no loss in your quality-of-life.

Heat Rises; Cool Air “Falls”

The first lesson to apply is a simple one: If you go back to 11th grade physics and remember that hot air rises, you can more easily cool your house in the summer by setting your fan to blow air downwards.

This will work in tandem with your optimized air conditioning unit to tamp down the effect of hot air coming in from the outside. Cool air will be much more easily able to circulate within the building and your overall IAQ will go up without you having to spend a great deal more money and energy tampering with the thermostat.

The Difference between Windchill and Actual Temperature Change

When weatherman speak of a windchill factor, they are speaking of a psychological difference between the actual temperature and the temperature that people feel on their skin. In order to raise the efficiency of your air conditioning unit and reduce your need for AC repair from overwork, you will need to take full advantage of the concept of a windchill factor.

Running your fans in the appropriate fashion along with your air conditioner circulates the air more readily inside of your living space. This increases the windchill factor inside of your home or office and makes it feel cooler or hotter than it actually is, depending on the rotation of your ventilation fans.

As stated in the first tip, if your fan is set to push air downwards, you will feel a cooler windchill factor. If it is set to push air upwards, you will feel a higher windchill factor. Either way, use this knowledge to your advantage so that your air conditioner will not be in constant need of AC repair from overwork in the hottest and coldest seasons of the year.
