Is an Attic Fan Worth It?
LESLIE: Now we’ve got Doug from Rhode Island who’s got a question about an attic fan. How can we help you with that?
DOUG: Somebody gave me a new, 15-inch attic fan. And I’m considering installing it but I also wondered, the electricity I’m going to use to run the fan, it’s maybe a wash. I don’t know. In other words, is it economical to run this attic fan?
TOM: Yeah. I’ll tell you what, I don’t have a good opinion of attic fans because what we have found – do you have central air conditioning in your house?
TOM: Well, what’s been found is that if you turn the attic fan on in the summertime, that it depressurizes the attic but it doesn’t stop there. It’ll reach down through the insulation – it’ll find all the little cracks and crevices in that ceiling space – and it’ll reach down into your house and it will start drawing off air-conditioned air and actually drive up your cooling costs.
So, I’m glad you didn’t have to pay for the attic fan but I wouldn’t put it in, if it was me. I would just make sure that my attic was well-ventilated, using passive vents. The most preferred are ridge vents and soffit vents.
DOUG: Yeah, I’m trying – I have sufficient vents.
TOM: Yeah. Then I don’t think you should put it in. I don’t think it’s going to help you and it could potentially hurt you.
DOUG: OK. No, I understand exactly what you’re saying.
DOUG: Thank you for your time.
TOM: You’re welcome. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
