London Plumbing & Remodeling: Attic Fans: Do they work, and should I get one?

Fun Tip Friday by London Plumbing & Remodeling

Before you know it the hot summer days & warm summer nights will be upon us. The air conditioner will be running & the electric meter will be spinning! Can an attic vent fan help reduce cooling costs & keep our homes cooler during the hot summer months?

Yes, they can IF properly installed. An attic fan will remove hot air from the attic space and discharge it to the outside of the house. Did you know that attics can reach temperatures of 150 to 160 degrees F during a summer day, although outside air temperatures are only 95 to 97 degrees F.

Exhausting the hot air allows the outside air to cool the attic. With a cooler attic less heat enters your home thru the ceiling and makes it easier to keep your house comfortable during those hot summer months. Your air conditioner or cooler will work less as the inside temperature of your home will be lower.

It is important to have the fan set with a thermostat (at about 100 degrees F +/-). We also like to install a switch to turn the fan off during the winter months, but this is optional. Many homes already have an attic fan but it is no longer working. Other homes have attic fans but they were installed improperly…what I mean by that is the fan is installed in the gable but there is no blocking around the rest of the vent. A large portion of the exchanged air is limited to the immediate area of the fan instead of having the air drawn thru the attic and cooling it.

Finally what is the cost of an attic fan replacement or new installation? That depends on many factors but the fans range in price from about $ 89.00 to $ 400.00 or more. Differences in price are due to energy efficiency, noise, & how effective are they at changing the air in the attic. Sometimes additional vents may need to be installed. Installation price will vary as well depending on the complexity of the job.
