Attic fan does it help.

Attic fans perform best when your attic is properly sealed and insulated to block the entry of heat and moist air. An attic fan helps get out warm air in the attic that can create a hot uncomfortable living place. So much more than just ventilation. An attic fan is what it sounds like it s a fan installed on the ceiling of your attic.

Attic ventilation fans help cool air your attic by pushing out the stifling hot air from inside the attic and bringing in cool air from outside. This prevents hot air from seeping into your home and driving up the temperature in the living space which reduces the load on your air conditioner. The good news is the above problems can be solved if you install an attic fan in your house. This allows it to improve your hvac efficiency and protect your roof shingles plus the structural integrity of your attic.

A powered attic ventilator has a different purpose. Mechanical fans this is where an attic fan can help. 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. It is designed to lower the temperature of an attic by exhausting air from the attic and replacing attic air with outdoor air.

The good thing is the devices operate using a thermostat therefore can automatically turn on and off with the desired temperatures. The humid air might cause condensation which might promote molds growth in the attic which is a health hazard. However if your attic has blocked soffit vents and is not well sealed from the rest of the house attic fans will suck cool conditioned air up out of the house and into the attic.

A significant amount of that cooling is likely to come from conditioned air being sucked up from the house below. One reason power attic ventilators don t help in my original article i focused on makeup air.
