Did you know a 1,500 sq ft attic needs at least 1,050 CFM of airflow for proper ventilation? Choosing the right size fan is key to keeping attics, garages and greenhouses cool and comfortable. Homeowners can choose from different options: solar powered fans that save energy, electric fans that run continuously or whole house fans that move air throughout the entire home.
Aitecac shutter exhaust fans are great for DIY installation. The 10 inch model gives 576 CFM and comes with an 11.5 ft power cord for easy setup. The 12-inch version gives 830 CFM, perfect for spaces up to 1,300 sq ft. Both are built with heavy duty, rust resistant metal and have automatic louvers to keep the system airtight. The best part is the automatic feature.Once installed the fan turns on and off by itself using a built in thermostat. This article will cover everything from measuring your space and gathering tools to wiring and setting up your new Aitecac ventilation system.
Gather Tools and Prepare the Space
Proper preparation is the foundation for a successful DIY installation of your Aitecac ventilation fan. Gathering the right equipment and creating a safe work environment beforehand prevents delays and potential hazards during DIY installation.
Tools needed for DIY installation
Before you start the installation process collect all the necessary tools to ensure a smooth workflow:
- Drill/driver with assorted bits
- Jigsaw for cutting openings* Standard and Phillips screwdrivers
- Hammer and wrench
- Utility knife and putty knife
- Tape measure and 2-ft level
- Wire cutters for electrical connections
- Caulk for sealing gaps
For mounting your Aitecac fan you will also need construction materials such as plywood and 2×4 lumber to create a stable mounting surface. Also have extension cords and a work light handy as attic visibility may be limited.
Safety gear and attic precautions
Safety should never be compromised during DIY ventilation projects. Essential protective equipment includes:
- Safety goggles to protect your eyes from debris
- Work gloves for hand protection
- Dust mask or N95 respirator to avoid inhaling insulation particles
- Long-sleeved shirts and pants to protect the skin
Beyond personal protection, exercise caution in the attic environment. First turn off the electricity at the main breaker box and test the wires to confirm power is off. Next step only on ceiling joists or place boards between them as temporary flooring stepping between joists could result in ceiling damage or personal injury.
Choosing the right time of day to work
Timing your installation can make a big difference in comfort and safety. Attics get extremely hot during peak daylight hours, so:
- Schedule your DIY installation during early morning or evening hours to avoid excessive heat
- Don’t do this project on extremely hot days
- Use a box fan to improve airflow in the workspace
- Stay hydrated throughout the installation process
Organize your tools and materials in advance so you don’t have to make multiple trips up and down the ladder. This will save you time and reduce fatigue during what can be a physically demanding DIY project.
Plan the Aitecac Fan Setup
Proper planning is the foundation of any successful attic ventilation project. Take the time to measure your space to ensure optimal performance of your Aitecac ventilation system.
Measure attic space and calculate CFM
First calculate your attic’s square footage by multiplying its length by its width. For a 1,000 sq ft attic multiply this area by 0.7 to determine the minimum CFM (Cubic Feet per Minute) rating needed – in this case 700 CFM. For steep roofs add 20% more capacity and for dark colored roofs add 15%. For attics that exceed 130°F in summer pose serious risks of heat exhaustion so proper sizing is crucial.

Choose the right Aitecac model
Now that you know how much airflow you need, choose an Aitecac model. The 576-CFM shutter-exhaust fan has built-in thermostats that turn on at preset temperatures and is good for spaces under 825 sq ft. For larger areas, look at Aitecac’s higher-capacity shutter exhaust fans for more airflow options while remaining energy efficient.
Gable or roof mount
Next, decide if a gable or roof mount is best for your home. Gable fans mount vertically on existing gable vents and push hot air out the gable. Roof mounted fans are partially in and out of the attic, as high as possible on the roof but at least 24 inches from the peak. For either option, make sure there is at least 3 feet of clearance from chimneys or vents.
Check for existing vents or fans
Finally, check your current ventilation system. A balanced attic ventilation system has intake vents (at the lowest points, usually soffits) and exhaust vents (at the highest points). Count the soffit, ridge or gable vents to make sure you have enough intake airflow, often overlooked. An insufficient intake area will compromise your fan’s performance regardless of its quality. For optimal performance, divide your fan’s CFM by 300 to calculate the minimum square feet of intake vent space needed.
Install the Shutter Exhaust Fan
The DIY installation phase marks the moment when your careful planning becomes reality. Following proper procedures ensures your ventilation system operates efficiently for years to come.
Cut the opening and frame the mount
First, create a template for your ceiling opening based on the shutter dimensions, not the fan itself. If working with existing joists, use a template to mark the exact opening size needed for your Aitecac shutter. For easier location identification, push a straightened wire through the ceiling near the center of your planned opening. Once in the attic, cut along marked lines using a jigsaw. Be careful not to damage structural supports. For stucco exteriors, a diamond blade in a circular saw or angle grinder makes clean cuts.
Attach the louver or shutter
Choose between premium or economy shutters based on your needs. Premium ceiling shutters have aluminum frames with galvanized reinforcement strips for added strength, economy models have simpler construction at a lower cost. Essentially, the shutter must be installed with louvers opening outward for exhaust applications. Attach the shutter frame to the opening according to manufacturer instructions, making sure tie rods allow for uniform blade opening.
Attach the fan to the mounting board
After creating a solid mounting surface, place the Aitecac fan centered over the opening. For joist installations, build a platform using 1″ x 4″ lumber nailed to the frame. Attach the fan by driving nails partway into the platform beside the plenum, two per side. This mounting technique creates an air seal, forming a duct from the living space to the fan.
Seal gaps with caulk or mastic
Proper sealing is key to maximum efficiency. For gaps 1/16″ to 1/8″ wide, apply mastic reinforced with fiberglass mesh tape. Seal between the roof and fan with roofing-grade caulk or mastic. For exterior applications, use elastomeric caulk like “Big Stretch” for weather resistance.

Wire and Configure the Ventilation Fan
Electrical work is the final stage of your Aitecac fan installation. Safety and proper connections will ensure your system works for years to come.
Find a power source
Safety first when working with electrical components. Turn off the power at the circuit breaker before starting any wiring work. For a permanent installation, do not use extension cords with modified plugs as these are fire hazards. Instead, consider having a dedicated outlet installed near the fan location by a licensed electrician.
Connect wires according to manufacturer’s instructions
After getting power, connect the wires according to standard color coding: black (hot) wire to black, white (neutral) wire to white, and green (ground) wire to the ground terminal. For dual-speed fans, connect the black wire to high speed and the red wire to the low speed terminal. Rotate the fan blade manually before turning the power back on to make sure there are no obstructions.
Install the thermostat or controller
Most Aitecac fans come with built-in thermostats that turn on automatically when the attic temperature rises. These usually have temperature adjustments between 50°F and 120°F using a dial. The thermostat should be in the attic, not at the switch location, to sense heat conditions.
Test the fan and adjust temperature settings
Once wired, turn the power back on and test:
- Listen for unusual sounds or vibrations
- Check airflow with a tissue near the vent
- Test any additional features like lights or sensors
Experts recommend setting attic fan thermostats between 90°F and 110°F. Some homeowners prefer 85°F to 90°F for cooler home temperatures.
Smart fan tips
For advanced control options consider upgrading to smart controllers. These allow temperature monitoring and fan control from your smartphone. Some DIYers use temperature sensors with smart outlets to create automated systems that turn fans on when specific temperatures are reached. No more climbing into hot attics for adjustments.
