In full general, almost homeowners should set their cranium fan temperature to in-betwixt ninety and 110 degrees Fahrenheit. Unfortunately, it is impossible to state a unmarried number as the right temperature. A house in sweltering New Orleans should have a completely different temperature setting than a home in northern Seattle. If the thermostat setting is as well high, so the cranium fan won't turn on or it volition turn on besides briefly.

And if the temperature setting is also low (such every bit 90-degrees in Miami) then the attic fan will be running more often than it needs to, possibly running 24-hours — wasting energy. Ideally, you lot want your cranium to exist shut in temperature to its outdoor surroundings.

Why Attic Fan Temperature Setting Is Important?

In my opinion as an inspector, the number ane reason is home condolement. When you have a libation attic, it just makes the whole firm much more comfortable. The HVAC doesn't have to run as hard or long to achieve its target temperature.

Houses with actually hot attics almost never reach their target temperature, and the firm is very uncomfortable — specially the 2d domicile level.

And the 3rd reason is something that well-nigh people don't think about. Decision-making your cranium temperature can aid extend the life of your asphalt roof.

Asphalt shingles is an oil-derived product, basically paper soaked in crude oil, and so these molecules lose their elasticity when heated up.

Well, attics can reach a temperature of 160-degrees on really hot days with poor ventilation. This will cook your shingles, making them brittle, and subject to cracking. It will besides give your shingles a faded look, greatly reducing its life.

Lastly, the correct attic fan setting volition help avoid moisture issues.

Attics and moisture simply don't mix. I take seen attics plagued by mold problems due to excessive moisture.

Mold simply needs three things to grow: wet, food, and darkness. Well, your attic has all three.
