A hot attic makes upstairs rooms hard to cool. We check the attic venting and air leaks before we install a fan.
Detroit attics get very hot in summer, especially over bungalows and story-and-a-half homes where the upstairs rooms sit right under the roof. An attic exhaust fan pulls hot air out so it does not soak into the ceilings below. We install and replace roof-mounted and gable-mounted attic fans, including thermostat-controlled and solar models. Many older homes already have a fan that has stopped working, and we can replace it in the same opening.
An attic fan works best with enough intake air from soffit or gable vents. Without intake, the fan can pull conditioned air out of the house through ceiling gaps, or even pull exhaust from gas appliances. We check the venting and the attic floor for air leaks before we install. In many homes, sealing the attic floor and adding insulation does as much as the fan.
In winter, the attic should stay cold and dry to prevent ice dams and condensation, so the fan should be set to stay off. A humidistat control can help in some homes. We explain how the fan fits with your insulation and air conditioning so it helps rather than working against your system. We also replace noisy or failed fan motors.
Attic fans in Detroit: common questions
Will an attic fan lower my cooling bill?
It can reduce heat in the attic and upstairs rooms, but only if the attic has enough intake air and the ceiling is sealed. We check both before recommending one.
Should my attic fan run in winter?
Usually no. A thermostat control keeps it off in cold weather. Running it in winter can pull warm, moist air into the attic.
My attic fan is loud. Can it be fixed?
Often the motor bearings are worn or the fan is loose on its mount. We replace the motor or the whole unit if it is old.
