Does My House Have An Attic Fan

Good insulation reduces fan effectiveness.

Does my house have an attic fan. Help purchased home 8 years ago with 2 power attic vents. However the utility of attic ventilation fans is actually quite a controversial topic. Essentially i do have a whole house fan but because of the rube goldberginess of my set up i was hoping to avoid full disclosure. Attic fans do cool down a house in less than an hour.

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. The downside of attic ventilation fans. Unlike a ventilation fan a whole house fan an attic mounted fan that exhausts air from a home at night is designed to cool a house that is to lower the indoor temperature. This is why an attic fan will help ventilate the attic and bring in cool air.

Whole house fans work on the principle of removing the hot and humid air out of the house. It is designed to lower the temperature of an attic by exhausting air from the attic and replacing attic air. A whole house fan is typically installed in the ceiling to your attic not in your roof. Things have been ok low energy bills house very comfortable.

My apologies for using the rather vague term power ventilation in my post. A powered attic ventilator has a different purpose. Noticed one of the attic vents was not working. The whole house fans takes hot air from the house and moves it up into the attic and out through the attic vents.

It helps to cool your home temperatures and the attic by approximately 30 degrees. Whole house fans need windows and doors open and attic fans need lots of soffit vents to suck cooler outdoor air up into the hot attic. The whole house fan is installed inside the attic between the living space and ceiling. The warm air escapes through the attic and to the attic vents allowing the circulation of chilly air from the windows.

A neighbor gave me an elderly propeller fan with an approximately 300w per kill a watt motor. Even though an attic exhaust fan can incrementally lower the temperature of a very hot attic using a fan does not stop the source radiant heat. The point here is that if you have a hot attic space it is going to shorten the life of any equipment residing there. A whole house fan is different than an attic fan.

Told that the 2 attic power vents are the only attic ventilation i have the house does have vented soffits every other soffit cover is vented.
