How can a solar attic fan reduce wear and tear on your home’s air conditioning system?

A solar attic fan can keep your house cool in the summer.

Staying cool over the hot summer months can be pricey. But with a solar attic fan, homeowners can harness the power of the summer sun to keep temperatures down while reducing overall reliance on air conditioning.   

Depending on the climate of where a home is located, air conditioning can increase a homeowner’s electricity bills by as much as 42 per cent. And North American homeowners certainly are not alone. Worldwide, one American study predicts that international air conditioning will triple by the year 2050. 

Needless to say, most homeowners will look for relief from more than just the summer heat in the coming years!

How can a solar attic fan help?

One way homeowners can cut down on electricity costs is by installing a solar attic fan. Solar attic fans work by boosting air circulation inside a home’s attic. 

Most roofs already come with built-in vents. However, these “passive” vents do not have any motorized or mechanical parts. They instead rely on differences in air density between the indoor and outdoor environment to stimulate air circulation. Passive ventilation alone usually suffices the minimum building code requirements. However, drastic shifts in outdoor and indoor temperatures can significantly hinder the amount of ventilation your home actually gets. 

When temperatures soar, these passive vents alone may not achieve optimal airflow. This traps the hot air inside your home’s attic. In turn, indoor temperatures are driven higher, causing your home’s air conditioning to work extra hard. 

Give your AC a much-needed break

Solar attic fans like iSolar Solutions’ popular 20W106-FLEX help lessen the load on a home’s air conditioning by giving passive vents a much-needed boost. These motorized fans automatically switch on when your home’s attic does not receive enough air circulation. They then switch off when not needed. 

This can lower a home’s temperature by as much as 10C in the summer. A home’s day-to-day air conditioning costs also decreases, along with wear and tear on air conditioning systems. Because solar attic fans rely solely on the sun, they add nothing to your home’s monthly electricity bills. Also, a solar attic fan can prolong the life of your roof’s shingles, which the overheated attics can damage. 

In areas where the summer heat comes with high humidity, solar attic fans also help homeowners ward off other potentially expensive repairs down the road. In addition to removing hot air, solar attic fans also prevent moisture from being trapped inside your home’s roof. If left untreated, moisture buildup can lead to rot, mildew and mould, leading to health problems and costly structural repairs.
