In sec 210.63 it states that a receptacle is required within 25' of all HVAC equipment. There is an exception that states,"A receptacle outlet shall not be required at one and two family dwellings for the service of evaporative coolers."
Someone said to me yesterday that a receptacle is no longer required within 25' of dwelling HVAC units. He was told that it was only required for commercial installs. He was told this by a local AHJ.
