Guide to Solar Attic Fans & Ventilation

Improve the comfort, efficiency, and longevity of your home by removing hot air and moisture from your attic

In Florida, the two biggest problems with attics are heat and humidity

A solar attic fan is a great way to regulate the temperatures in your attic and help your air conditioning work more efficiently. 

Attic fans are a more affordable solution to replacing your air conditioning unit due to its lack of inefficiency. 

The Advantages of a Solar Attic Fan

  • Lowers electricity/utility/maintenance bills
  • Keeps roof structures and materials from deteriorating
  • Prolongs the lifespan of your roof and AC unit
  • Keep your attic cool in the summer by reducing extreme heat buildup in your home
  • Help eliminate mold
  • Reduce damaging moisture
  • Durable and easy to install in a few hours because there is no wiring, assembly or mess to clean up afterward
  • Eco Friendly – Solar attic fans are a “green” and sustainable way to ventilate your attic without electricity (they have a built-in photovoltaic power system that uses the energy of the sun to power the fan)
  • Helps your home battle the Florida heat and humidity
  • Eligible for 30% federal tax credit
  • Much less expensive than replacing your air conditioning unit
  • No fire hazards
  • Hurricane proof

How do Solar Attic Vent Fans Work?

Solar attic vent fans run on power from the sun and pull superheated air out of your attic to be replaced by cooler outside air. This reduces the amount of work your HVAC system has to do to cool your upstairs living area. This can prolong the lifespan of your air conditioning unit and is a great alternative to replacing your air conditioning unit 

This solution is much more effective than relying on small passive vents at moving air to expel heat and moisture. A hot attic acts like a giant radiator, transferring heat into your living spaces, sending both utility bills and temperatures soaring. Not only does an attic fan save you money through the use of solar power, but it also takes a bite out of electric bills because it regulates the temperature within your attic improving the efficiency of your AC unit.

How can a solar attic fan help improve the efficiency of your home’s AC unit?

Living in Florida means lots of sunshine. When the areas of our home are not properly insulated or ventilated, heat and moisture can get trapped and then transferred into our living space. We have to bump up the thermostat to compensate for the increase in heat. A solar attic fan helps to disperse that heat and cool off our attics and thus, cool off our living space and lower our electric bills because the AC unit is not having to work as hard nor do we have to keep playing with the thermostat to find a comfortable temperature.

 The Solar Attic Fan also makes your home temperature more comfortable overall and helps to prevent moisture and mold from building up in your attic, which can cause wood deterioration and health problems.
