Whether you’re shopping for a small fan for a compact garage or a heavy duty model for a workshop, following these steps ensures your ventilation system works as intended.

Common mistakes to avoid when ventilating your garage

Overlooking Proper Sizing and CFM Ratings

One of the most common mistakes is choosing a garage vent fan without checking if its CFM (cubic feet per minute) rating matches your garage size. A fan with too low CFM won’t effectively remove fumes, heat, or humidity. On the other hand, an oversized fan may waste energy and increase your electricity bill. Always compare the CFM rating to your garage’s square footage and ceiling height to ensure efficient ventilation.

Ignoring Placement and Ventilation Pathways

Where you install your exhaust fan or vent fan matters. Placing a fan in a corner or without a clear pathway for air to exit can trap pollutants and reduce airflow. For best results, position the fan on a wall opposite to the main air intake or garage door. Make sure attic or wall vents are not blocked by storage or insulation. This helps maintain a steady flow of fresh air and prevents hot spots, especially in garages attached to the house or attic garage setups.

Skipping Shutter and Backdraft Protection

Many forget to check if their chosen product includes a shutter or backdraft damper. Without these, outside air, dust, or even pests can enter when the fan is off. Shutters also help maintain temperature and humidity control, which is crucial for garages storing sensitive items or serving as workshops.

Neglecting Energy Efficiency and Motor Quality

It’s tempting to focus only on price, but a cheap fan with a low-quality motor can end up costing more in repairs or energy bills. Look for energy efficient models, especially if you plan to run the fan for long periods. Solar powered options can be a smart investment for reducing electricity use in sunny climates.

Improper Installation and Wiring

DIY installation can save money, but mistakes like poor wiring or insecure mounting can create fire hazards or reduce the lifespan of your fan. Always follow manufacturer instructions, use proper electrical connections, and consider professional help for heavy duty or attic installations.

Forgetting Maintenance and Cleaning

Even the top garage fans need regular cleaning. Dust buildup on blades, shutters, or vents can lower efficiency and air quality. Set a reminder to inspect and clean your exhaust fan, attic fan, or wall vent every few months, especially if your garage is used as a shop or for projects that generate debris.

• Check fan cfm and match to garage size
• Ensure proper placement for airflow
• Look for shutters or dampers
• Prioritize energy efficient, quality motors
• Install safely and securely
• Maintain and clean regularly

By avoiding these mistakes, you’ll get the most out of your garage ventilation system, whether you’re using a small exhaust fan, a heavy duty attic fan, or a solar powered vent. This helps keep your garage, house, and workshop air cleaner and safer.
