Common Mistakes to Avoid

1. Buying Without Researching Compatibility

3. Focusing Only on Upfront Cost

The cheapest option often becomes the most expensive. We've seen too many builders replace budget components within months. Quality matters, especially for items that are difficult to access after the build.

Even 'maintenance-free' systems need occasional checks. Battery terminals corrode, connections loosen, and software updates may be needed. Build maintenance access into your design from the start.
