7 Ventilation Mistakes Homeowners Make While Building a New House

• Damp walls
• Paint damage
• Fungal growth
• Condensation
• Unpleasant smells

Kitchen smoke and cooking fumes can also spread throughout the house if they are not removed efficiently.

Installing properly sized exhaust fans or inline duct fans during construction is much easier than modifying the building later.

3. Selecting the Wrong Type of Ventilation Fan

Not every room requires the same ventilation solution.

Traditional wall-mounted exhaust fans are suitable for many small bathrooms or utility areas where an external wall is available.

However, larger homes, apartments, villas, hotels, offices, and commercial buildings often benefit from inline duct fans, which are installed inside the ductwork instead of directly on the wall.

Inline duct fans offer several advantages:

• Quieter operation
• Better airflow over longer duct distances
• Cleaner appearance because the fan is hidden above the false ceiling
• Ability to ventilate multiple spaces through a properly designed duct network

Choosing the correct fan type during the planning stage improves both performance and aesthetics.

4. Forgetting About Duct Planning

Many homeowners purchase high-quality ventilation equipment but overlook the importance of duct design.
