Know Your Limits

DIY repair saves money and builds skills. But some repairs require specialized tools, certifications, or pose serious safety risks. Knowing when to stop can save your device—and your safety.

Call a Pro For

Gas appliances: Boilers, furnaces, and gas stoves require Gas Safe or equivalent certification. Gas leaks are dangerous. Refrigerant work: HVAC and fridge sealed systems need EPA certification. High voltage: Microwave capacitors, CRT TVs, and some power supplies hold lethal charge. Warranty concerns: Opening some devices voids warranty—weigh the cost.

DIY-Friendly Repairs

Screen replacements, battery swaps, filter cleaning, belt changes, and most mechanical repairs are within reach with guides and basic tools. Start with low-risk items and build confidence.

Red Flags to Stop

If you smell gas, see sparks, or feel unsure about electrical work—stop. If a repair requires specialized calibration (e.g., boiler combustion) or you lack the tools—call a pro. Your safety and the device's integrity matter more than saving a few dollars.
