Attics provide a place to stash dusty photo albums, antique trains sets, and the cricket bat your great-grandpa used to kill the last living T-Rex. Keep crowded crawlspaces cool with today’s Groupon to U.S. Sunlight Corporation. This Groupon is valid in the San Francisco Bay Area, including East and South Bay (a 20-mile radius of 94506, 94110, 94064). Choose between the following options:
- For $349, you get a 9910TR solar-powered attic fan (a $399 value) and installation (a $300 value; a $699 total value).
- For $49, you can upgrade the system by installing a solar controller (a $99 value). This option is only valid with the purchase of the fan option.
U.S. Sunlight's solar-powered fans increase airflow and circulation to ventilate attics and lower interior temperatures, making homes more comfortable. Each fan is tested to withstand high-pressure wind loads of up to 150 psf and are capable of driving out excess hot air to reduce the strain on air conditioners and prevent attic heat from seeping down into homes. In addition, U.S. Sunlight's 9910TR Model helps extend the life of roofing and construction materials by decreasing humidity that can cause saturated insulation and cracks in the drywall. Fans will also prevent moist air accumulation that can lead to mold and mildew in spaces up to 1,150 square feet.
Homeowners can also upgrade units to include a solar controller with today's Groupon. A solar controller displays attic temperature and humidity, providing homeowners with real-time status updates on a handheld remote. Cycling electricity from the house for eight minutes every half hour, solar controllers will allow attic fans to operate after dark and during spontaneous month-long solar eclipses.
