How to Install Exhaust Fan in Wall – A Practical Guide for Ghanaian Homes and Businesses

Ghanaians are no strangers to heat, humidity, and indoor smoke — especially in kitchens, bathrooms, and enclosed spaces with poor airflow. Whether you’re living in Accra, Kumasi, Takoradi, or Tamale, having a proper ventilation system is key to a healthier and more comfortable indoor environment. One of the most effective solutions is to install an exhaust fan in the wall.

This article walks you through how to install an exhaust fan in a wall, with tips relevant to Ghana’s homes, restaurants, offices, and small businesses. You’ll also discover how professional services can ensure your installation is safe, durable, and efficient.

Why Install an Exhaust Fan in Your Wall?

Before diving into the steps, let’s understand why so many Ghanaians are turning to wall-mounted exhaust fans:

• Removes Smoke & Odours: Especially useful for Ghanaian kitchens, where fried plantain, grilled fish, and banku are regularly cooked.
• Reduces Heat & Humidity: Wall exhaust fans keep indoor air cooler during Ghana’s hot seasons.
• Prevents Mold & Dampness: Essential in bathrooms and storage rooms where humidity levels are high.
• Improves Air Circulation: Especially in homes and buildings without central HVAC systems.

Tools & Materials Needed for Wall Exhaust Fan Installation

If you’re planning to install the exhaust fan yourself, make sure you have:

• Wall exhaust fan (right size and type)
• Measuring tape and pencil
• Power drill or wall cutter
• Screwdriver, screws, and wall plugs
• Sealant or putty
• Protective gloves and goggles
• Electrical wire and connectors (if applicable)

Tip: If you’re unsure about wall structure, wiring, or tools, always hire a professional.

How to Install Exhaust Fan in Wall – Step-by-Step (Ghana Edition)

Step 1: Choose the Right Exhaust Fan

Consider your space type and size. Common fan types include:

• Kitchen wall exhaust fan in Ghana
• Bathroom wall-mounted ventilation fan
• Wall extractor fan for commercial kitchens

Look for low-noise, energy-efficient models suitable for Ghana’s warm climate.

Step 2: Select the Wall and Mark Dimensions

• Choose a high wall location, near the ceiling, for maximum airflow.
• Mark the area using the fan’s template or measurement.

Step 3: Cut the Wall Opening

Use a masonry drill or wall cutter to create the opening. Be extra cautious if you’re cutting through:

• Concrete walls
• Tiled surfaces in kitchens or bathrooms

If this step feels risky, professional wall cutting services in Ghana are available.

Step 4: Mount the Exhaust Fan

• Insert the fan into the hole
• Screw it into place using wall plugs
• Seal gaps with waterproof putty to prevent rain or insects

Step 5: Connect to Power Supply

• Shut off power from the main source
• Connect the fan wires (live, neutral, and ground) to your existing power circuit
• Use wire connectors for safety

Warning: This step should be done by a certified electrician to prevent fire or electrocution.

Step 6: Test the Fan

Once installed and connected, test the fan for:

• Proper airflow
• Noise level
• Smooth operation
• No air leaks around the installation
