Attic Fan Save money on air conditioning

Cool down your attic with an attic fan from JR Putman

Attic Fan: The inside scoop

Excessive summer heat in the attic can hinder the performance of an air conditioning system. The installation of an attic exhaust fan can alleviate this problem.

A general rule of thumb is to provide an attic fan for every 300 sq. foot of area.

An attic exhaust fan typically is an electrical-powered fan mounted in such a way as to remove hot air from attic spaces. Most units come equipped with an electronic or mechanical thermostat that automatically turns the power on when attic temperatures reach a specified level.

There are many benefits associated with the ventilation provided by an attic exhaust fan.

  • The money saved on air conditioning bills in one season can pay for the cost of the fan and the installation fees. In some cases, air conditioning might not be necessary after an attic exhaust fan is in use.
  • Many people find that the temperature in the house noticeably drops when an attic fan is turned on. This is another benefit to attic fans. While air conditioners can take longer to cool a house, an attic fan changes the temperature in a more immediate way.
  • Avid mold and moisture build-up. The air temperature inside the attic should be the same as the outdoor temperature. This will eliminate moisture on interior surfaces of the attic and underneath roofing materials
  • If the attic exhaust fan motor ever wears out, the fan motor can usually be replaced without a complete installation of a new unit. This procedure is easily accomplished from inside the attic rather than from on the roof. Thermostats are also easily replaced.
  • Installing an attic exhaust fan is a home improvement that quickly pays for itself. Savings in air conditioning costs far outweigh the cost of electricity for running the fan.

Attic exhaust fans come in basically two styles.

  1. One style mounts in the gable end, drawing air through the attic, usually through a stationary vent in the other gable end. The fan is mounted behind a set of louvers that prevent rain and extreme weather from damaging the unit.
  2. The other style of attic exhaust fan is mounted on the roof, normally near the top ridge of the roof. Air is drawn through vents in the overhang of the roof. Various combinations of air supply vents are common.
