Yeah I read through that posting and I’m still not convinced that the original poster there is on to much. To add to all of the disagreements in the comments there, I also noticed that my AC works much less hard on hotter days, and noticed a slight reduction in costs monthly electrical costs year of year. There are a lot of variables in play to go into an electrical bill however.
- amluto 7y agoIt seems plausible to me that if you have decent air sealing in your house and wildly inadequate ceiling insulation then an attic fan could help. Or if you have poor air sealing but you have enough space for outside air to enter your attic. In a well-built house, the roof and ceiling shouldn’t be a major source of summer heat gain.
