How to Install Exhaust Fan in Wall – The Ultimate Guide for Homes and Businesses in Ghana

In Ghana, whether you’re in a small apartment in Accra, a busy restaurant in Kumasi, or a school kitchen in Tamale, ventilation is not just a luxury—it’s a necessity. Ghana’s warm climate, frequent indoor cooking, and limited airflow in many buildings make it critical to remove heat, smoke, and odours from enclosed spaces. One of the most effective solutions? Installing a wall-mounted exhaust fan.

This comprehensive guide explains how to install an exhaust fan in a wall, tailored for Ghanaian residential, commercial, and industrial spaces. If DIY is not your thing—or if you want guaranteed, safe, and long-lasting installation—CETECH Ghana Services HVAC-R Division is ready to help.

Why Wall Exhaust Fan Installation Is Important in Ghana

1. Ghana’s Climate and Heat Levels

In many parts of Ghana, temperatures are consistently high throughout the year. Cooking or operating machinery indoors without ventilation causes extreme heat buildup. A wall exhaust fan for hot rooms in Ghana helps eject warm air and bring in cooler airflow.

2. Smoke and Odor Removal

Local dishes like kelewele, fufu with goat soup, fried yam, and grilled tilapia create strong smells and heavy smoke. A wall exhaust fan for kitchen smoke removal keeps your home or restaurant comfortable and odor-free.

3. Health and Air Quality

Mold and mildew thrive in poorly ventilated spaces. In bathrooms, shops, and storage rooms, a wall fan for moisture and humidity control protects your health and building.

Tools and Materials for Wall Exhaust Fan Installation

To successfully install a wall exhaust fan, here’s what you’ll need:

• Exhaust fan (choose the correct size and type)
• Measuring tape and pencil
• Wall drill, hammer drill, or masonry cutter
• Screwdrivers, screws, wall plugs
• Electrical wire and connectors
• Weatherproof sealant or mortar
• Safety gloves and goggles

Step-by-Step: How to Install Exhaust Fan in Wall

Step 1: Select the Right Exhaust Fan

Different rooms require different fan sizes and power. For example:

• Kitchen exhaust fan for wall ventilation
• Bathroom moisture control wall fan
• Commercial shop exhaust fan with high airflow

Tip: CETECH Ghana helps you select the best wall exhaust fan model for your specific need.

Step 2: Mark the Installation Spot

Choose a location high on the wall, near the ceiling, and opposite the air entry point. Make sure it’s away from wiring, plumbing, and beams. Mark the fan’s diameter with a pencil.

Step 3: Cut the Hole in the Wall

Use a hole saw or masonry cutter to cut through concrete or block. For tiled kitchens or bathrooms, be extra careful to avoid cracks.

Tip: This step often requires professional power tools and expertise. CETECH Ghana offers wall cutting and core drilling services for exhaust fan installations.

Step 4: Secure the Exhaust Fan

Insert the exhaust fan into the hole and screw the mounting plate securely to the wall. Seal any gaps with waterproof putty or sealant to prevent rain and air leaks.

Step 5: Wire the Fan to Power Supply

Turn off the main electricity. Connect the fan’s live, neutral, and ground wires to a suitable power line or switch. Some models come with plug-in options, while others need hardwiring.

Important: This step should only be done by a qualified electrician or HVAC technician. CETECH Ghana provides safe and certified electrical connections.

Step 6: Test the Fan

Turn on the power and test the exhaust fan. Check for:

• Proper airflow
• Quiet operation
• No vibration
• No air leaks around the installation
