Hello, all. We have a 25-30 year old attic fan that is very inefficient at venting air through the attic. We need to do something. What product would you recommend to improve the situation?
do you mean a powered attic ventilator (pav)
a fan controlled by a tstat & installed
in the decking of the roof to pull hot air
out of attic?
what combination of ventilation do you have?
any soffit vents to allow cool air to enter attic?
gable end venting?
soffit and ridge vents?
soffit and pav's?
answer depends on these factors.
if you have soffit and pav..replace pav
with passive ventilators.
pav's pull conditioned air from inside
living space to cool attic.
or do you have a whole house fan
that is in the ceiling of the house
and pulls house air thru open windows
& into attic?
hard to tell from your post.
best of luck.
