Sometimes we come across installs that leave us scratching our heads. Case in point: this “double disconnect” setup we found recently. Instead of properly removing and replacing the old disconnect, someone decided to mount the new one inside the shell of the old one.
It might look like it works, but here’s why shortcuts like this can be risky:
Safety hazards: Electrical connections need to be properly secured and protected. Nesting a new disconnect inside the old housing can trap heat, increase corrosion risk, and compromise grounding.
Code compliance: This type of setup won’t pass inspection in most Florida counties. Codes are in place to keep homeowners safe and equipment running reliably.
Future repairs: When the next tech shows up, they’ll have to sort through this puzzle box before even starting the repair — meaning more time, and potentially more cost, for the homeowner.
At Cool Air M.D., we believe in doing things right the first time. That means safe, clean, code-compliant installs that give you peace of mind and reliable comfort for years to come.
If you’ve ever wondered whether your HVAC or electrical setup was done correctly, it’s worth having a pro take a look. We’ll make sure everything is safe, efficient, and built to last — no nesting dolls required.
