Is attic venting necessary in summer.

Attic ventilation in the winter. Can i put a small swamp cooler or ventless a c unit up there to cool it only to use while i am in my shop maybe an hour or two a couple times a week. If your attic seems to get as hot as your car s interior on a warm sunny day you probably need better attic ventilation. Cars and attics can reach 140 degrees f and higher and all that heat doesn t do either one of them any good.

Attics aren t really ever seen by homeowners and you probably don t use yours on a regular basis so it s easy to lose sight of of your attic s condition but it s also crucial that you don t. Good insulation reduces fan effectiveness. In fact problems like mold and mildew and hot attic temperatures in summer can all be offset by adequate attic ventilation. Attic ventilation fans whether hard wired or powered by their own solar panels seem like a low cost and effective way to help keep your house cool.

In winter for instance attic vents help to remove moisture from the home. While heat migrates in the summer because your attic is acting as a giant pressure cooker in the winter the attic space is colder allowing more room for the heat to rise and bring all that warm cozy. The downside of attic ventilation fans. I have a shop in my attic for some of my hobbies and it get s very hot in the summer.

When properly constructed the vents create a draft in the attic that promotes evaporation of condensation and creates a cooling effect on hot summer days. You would think that venting an attic would be counterintuitive in the winter or cold months. Attic ventilation plays an important role in maintaining a comfortable environment in the home. However the utility of attic ventilation fans is actually quite a controversial topic.
