While DIY repairs can save money, they can also be risky, especially if you lack the necessary skills and tools. Some minor issues, like cleaning filters or changing a light bulb, can be handled easily without professional help. However, more complex issues, such as electrical or mechanical failures, should be handled by a trained technician. Attempting DIY repairs without proper knowledge can lead to further damage, void warranties, or even cause safety hazards. It’s often more cost-effective and safer to hire a professional to ensure the repair is done correctly and efficiently.
