Beat the Aiken heat and reduce your summer electric bills with professional attic fan installation from Unity Power & Light. Our powered attic ventilators actively exhaust superheated air from your attic, reducing cooling costs by 10-30% while extending the life of your roof and HVAC system.
As licensed electrical contractors serving Aiken and surrounding communities, we provide expert installation of electric and solar attic fans tailored to your home's specific needs. From initial assessment through final testing, we ensure your attic ventilation system performs optimally for years to come.
Why Aiken Homes Need Attic Fans
Aiken's summer heat is intense. While outdoor temperatures regularly hit 90-95 degrees from June through September, your attic can reach a scorching 140-160 degrees—hot enough to cook an egg on your roof decking.
This extreme heat doesn't stay isolated in your attic. It radiates down through your ceiling, making your air conditioner work overtime to maintain comfortable temperatures in your living spaces. The result? Sky-high electric bills and an HVAC system that runs constantly but never seems to catch up.
An attic fan solves this problem by actively pulling hot air out of your attic and replacing it with cooler outside air. By reducing attic temperatures by 20-50 degrees, you dramatically reduce the heat load on your air conditioning system.

Our Attic Fan Installation Services
Powered Attic Ventilator Installation
Traditional electric attic fans provide reliable, powerful ventilation for homes of all sizes. These fans connect to your home's electrical system and use thermostats to automatically turn on when attic temperatures reach a preset threshold (typically 90-110 degrees).
What we provide:
- Complete ventilation assessment
- Proper fan sizing for your attic volume
- Gable-mount or roof-mount installation
- Adjustable thermostat installation
- Professional electrical connections
- Weatherproof roof penetrations (roof-mount)
- Intake ventilation evaluation and upgrades
- Performance testing and optimization
Electric attic fans are ideal for homeowners who want maximum airflow and reliable performance regardless of weather conditions. Modern units are remarkably energy-efficient, typically costing only $25-40 per summer to operate.
Solar Attic Fan Installation
Solar-powered attic fans use photovoltaic panels to generate electricity, requiring no connection to your home's electrical system. This means zero operating costs—the fan runs entirely on free solar energy.
Advantages of solar attic fans:
- Zero operating costs—powered by the sun
- Environmentally friendly and sustainable
- No electrical wiring required
- Operates during peak heat when sun is strongest
- May qualify for federal solar tax credits
- Simple installation with no electrical connections
Aiken's abundant sunshine—we average over 220 sunny days per year—makes solar attic fans particularly effective in our area. The fan runs hardest during sunny afternoons when attic temperatures peak, providing cooling exactly when you need it most.
We carefully position solar panels to receive optimal sunlight throughout the day and select fan models sized appropriately for your attic's cubic footage.
Thermostat-Controlled Units
All of our attic fan installations include intelligent thermostat controls that automatically manage fan operation based on attic temperature. This ensures the fan runs only when needed, maximizing efficiency and lifespan.
Thermostat features:
- Adjustable temperature settings (typically 90-110°F)
- Automatic on/off operation
- No manual intervention required
- Prevents unnecessary operation during cool weather
For Aiken homes, we typically recommend setting thermostats to activate around 95-100 degrees. This ensures the fan runs during hot summer days without cycling unnecessarily when attic temperatures are already reasonable.
Humidistat Options
In addition to temperature-based controls, many attic fans offer humidistat controls that activate the fan when humidity levels become excessive. This is particularly valuable in Aiken's humid climate.
Aiken's summer humidity regularly reaches 70-90%, and moisture can accumulate in attics even when temperatures aren't extremely high. A humidistat-controlled fan addresses this by running when humidity threatens to cause mold, mildew, or wood rot—protecting your home year-round, not just during the hottest months.
We can install fans with both thermostat and humidistat controls for comprehensive protection. The fan activates based on whichever condition is met first—high temperature or high humidity.
Proper Ventilation Assessment
Installing an attic fan is only half the equation. For optimal performance, your attic must have adequate intake ventilation. Without sufficient intake vents, the fan will pull air from your living spaces instead of from outside—a problem called "backdrafting" that actually works against you.
Our comprehensive ventilation assessment includes:
- Calculation of required intake ventilation based on fan size
- Evaluation of existing soffit, gable, and ridge vents
- Identification of ventilation deficiencies
- Recommendations for additional intake vents if needed
- Installation of supplemental vents to meet requirements
Many older Aiken homes don't have adequate soffit ventilation. We'll identify this during our assessment and can install additional soffit vents, gable vents, or other intake ventilation to ensure your attic fan performs as intended.
Our Installation Process
Free In-Home Assessment
We visit your Aiken home to evaluate your attic's size, current ventilation, insulation levels, and temperature conditions. We'll discuss your cooling challenges and energy goals to determine if an attic fan is the right solution for you.
Ventilation Calculation and Design
We calculate your attic's cubic footage to properly size the fan, assess existing intake ventilation, determine optimal fan placement (gable vs. roof-mount), and identify any additional ventilation needs. We'll provide a detailed written proposal with equipment specifications and pricing.
Professional Installation
Our licensed electricians install your attic fan with meticulous attention to detail. For roof-mount installations, we create weatherproof penetrations with proper flashing and sealing. For gable-mount units, we ensure secure mounting and proper fit. All electrical connections are made to code with appropriate circuit protection.
Intake Ventilation Installation (If Needed)
If your existing intake ventilation is insufficient, we install additional soffit vents, gable vents, or other intake ventilation to ensure balanced airflow. This critical step ensures your fan pulls air from outside, not from your living spaces.
Thermostat Calibration and Testing
We set and test the thermostat to ensure the fan activates at the correct temperature, verify proper airflow throughout the attic, check for any air leaks or backdrafting, and ensure the fan operates quietly and efficiently.
System Explanation and Recommendations
Before we leave, we explain how your attic fan system works, demonstrate the thermostat controls, provide maintenance recommendations, and answer any questions you have. We want you to fully understand your new system and feel confident it's working correctly.

Return on Investment
The average Aiken homeowner saves $60-90 per summer on cooling costs with an attic fan—a 10-15% reduction in air conditioning expenses. Over the typical 15-20 year lifespan of an attic fan, that's $900-1,800 in savings, well beyond the installation cost. Factor in extended AC system life and roof protection, and the ROI becomes even more compelling.
Choosing the Right Attic Fan for Your Home
Gable-Mount vs. Roof-Mount
Gable-mount fans install in existing gable vents at the end walls of your attic. They're typically less expensive and don't require roof penetrations. They work well for homes with straightforward attic configurations and adequate gable vents.
Roof-mount fans install directly on your roof, usually near the peak. They provide superior ventilation for complex attic spaces, homes with hip roofs (common in Aiken), or homes without suitable gable vents. They require weatherproof roof penetrations but are often the better choice for larger or more complex homes.
Electric vs. Solar
Electric fans typically move more air and run regardless of weather conditions. They cost $25-40 per summer to operate and require electrical connections. Best for maximum performance and homes with complex cooling needs.
Solar fans cost more upfront but have zero operating costs. They run hardest when the sun is strongest—exactly when attic heat peaks. Best for environmentally conscious homeowners and those seeking long-term operating cost savings. Aiken's sunny climate makes solar fans particularly effective here.
