| satisfying results. The whole
house fan is most effective when outside air temperatures
are below 82ºF. It brings a cooling breeze in through
the windows of the home and cools more efficiently than
an air-conditioner. When the temperature climbs above
that and you decide to use air conditioning you can shut
the windows and crank up the air knowing that the attic
fan will save up to 30% on cooling costs by getting rid
of trapped super hot air that tends to collect in attics
and cause heat to back up into the home.
Attic temperatures can get up to 150ºF without
an attic fan. Attic fans create a positive air-flow
through your attic that does not rely on wind or require
excessive passive venting. Excessive passive venting
can cause excessive moisture infiltration in the form
of snow or rain. The attic fan is normally mounted up
on the roof of the home toward the back about two feet
down from the peak. It goes on and off automatically
with a thermostat, so it only runs when it is beneficial.
The attic fan has a flashing that fits in with the shingles
and is water-proof. Attic fans use less than 250 Watts,
and offer these important advantages:
1. Lowers upstairs room temperatures by 10º.
2. Lengthens roof life by keeping shingles cooler.
3. With an optional humidistat, keep attics dry during
winter months.
4. Saves up to 30% on air-conditioning costs.
The exact savings obtained depends on several factors
like: the color of your roof, if the home is shaded,
the amount of insulation you have, and the efficiency
of your cooling system. Ideally, an attic fan installation
will pay for itself within 3 years. A high quality attic
fan is recommended. A heavy screen is required to stop
pests. All metal construction is preferred as plastic
fans do not hold up as well and over time will crack.
A quality thermostat is also essential to save from
climbing up into the attic for resetting. A fire stat,
which shuts the attic fan off for extremely high temperatures,
is needed in case of a home fire. A permanently lubricated
motor, insures quiet, maintenance-free operation.
