Short Answer
YesNo part of a heating, ventilating or air conditioning system may be installed, altered or replaced without a Mechanical Permit. For single-family homes and duplexes, replacing a furnace, air handler, condensing unit, heat pump or mini-split uses a Simple No-Plan permit that is issued once you apply online and pay; repair-only work needs no permit.
