Today it seems like air conditioning has always been around. But in 1965 only 10% of American homes had an air conditioner and, around Florida and most of the Sunbelt, it was ofttimes only a single window-unit in the sitting room operating theatre master bedchamber.

    A pop way to keep the house cozy in hot summer months was to open upward all the windows and devolve on a whole-house fan. It pulled fresh exterior air into the house from a central location in the home—usually the cap of the hallway—and sucked information technology into the territory, push house air unfashionable finished the attic vents, along with any accumulated attic heat.

    They were the freehanded big-ass fans, moved a tremendous volume of air, and created a continuous breeze throughout the household. Although a whole house fan does non aplomb the air, the constant menstruate of air around a person has a temperature reduction effect similar to standing under a ceiling devotee. One disadvantage compared to free-flying conditioning is that IT does not dehumidify. So, connected a Day with high humidity, the devotee too pulls the humid air into the house.

    The swelled nonnegative for a whole house devotee, though, is low energy usage, and they were a stock feature in many Gainesville homes upwardly until the late 1960s. It may live old technology but, accordant to the U.S. Department of  Energy, whole house fans are also along the ahead of butt on of energy-economic solutions for the 21st hundred. Here's the DOE's cost comparing to air conditioning:

First Cost Benefit

Equipment toll for whole house fan = $150 to $350

Equipment price for window Actinium = $250 to $750

Equipment cost for central AC = $2,000 to $4,000

Economics of Operation

Operating a properly sized 2-ton air conditioner with seasonal energy efficiency of 10 in Battle of Atlanta, Georgia, costs complete $250 per cooling season (1,250 hours), based happening 8.5¢/kWh, or roughly 20¢ per hour of runtime.

A large 18,000 BTU/h window unit of measurement air conditioner with energy efficiency (EER) of 8.8 costs more than 17¢ to work for one hour.

By contrast, a whole house sports fan has a motor in the 1/4 to 1/2 hp range, uses 120 to 600 Watts, and costs around 1¢ to 5¢ per hour of use.

     A unhurt house fan can be used as the only agency of cooling or to reduce  the need for air conditioner. If both methods of cooling system are present, seasonal manipulation of the whole house fan (during the spring and fall) May yield the optimal combination of comfort and monetary value.

    Because of the high humidness in near of Florida and the Sou'-east U.S. during summer months, use of a whole menage fan during jump and fall give the most sense around here. So, if 1) you are buying a home with an old completely house fan that is still functional and, 2) you enjoy opening up the house during cool and moderately warm weather, then definitely keep it and consumption it until the high humidness days go far.

    But a whole star sign sports fan turns from energy-saver to an vim-waster during heating and air conditioner months unless IT can be sealed and insulated during those multiplication. The metal louvers close up automatically when the fan is upside-down off but, because IT is similar to having a jalousie window in the ceiling of the house, the lack of insulation and air escape around the louvers creates an energy-suction jam into the attic.

    If you don't plan on using the fan, then we recommend removing IT, repairing the ceiling and insulating the attic orbit above it. But, if you want to exact advantage of the benefits of a whole house fan, then a cover needs to be constructed to breeze-seal and isolate around it. The DOE has published an informative whole home fan brochure, that includes instructions and plans for building an off-season cover at the ceiling and insulated box in the attic for your fan.

    One thing you need to embody careful about when exploitation a whole menage winnow is backdrafting of combustion appliances, such as a gas hot-water heater. This is a problem created when the suction created past the fan can causes burning gases that would ordinarily mount the fluke to be pulled back into the home. If your appliances don't use room melodic line—put differently, they are in a compartment operating theatre press covered from the lie of the home—it's not a job. Other than, you should consult a gas appliance professional person before exploitation your whole house lover.

    If you have a beat fan, a really whirring old one, or are considering installing a whole sign of the zodiac fan in your habitation for the first time, ace good resource is www.wholehousefan.com. They can aid you specify the right size fan to buy, sell you the fan, and then help you put in it right wing with video instructions.

   By the way, if you seaport't seen a undiversified mansion fan in front, the photos at a lower place show what one looks like when off off, with the louvers closed, and also from the attic (without the inactive-season cover box).
