Question:
I had a new Carrier a/c unit installed this past July, 2017. The old unit had a disconnect box on it but the a/c guy did not install a disconnect box to my new unit and he refuses to install one. Can you post the electrical code that specifically says that a disconnect box needs to be installed either on the a/c unit or very near it, please? Thank you.

Answer:
Hey Debra thanks for your question. A disconnecting means for air conditioning and refrigeration equipment must be installed within sight and readily accessible from that type of equipment as stated in 440.14. The second sentence of that section allows the disconnecting means to be on or within the equipment. If a disconnecting means is provided integral with the AC unit then an additional one is not required by the NEC.
