The license class decides who may open a city system
The city license is specific enough to ask about by name. A Class A Master HVAC license covers any heating, ventilating or air conditioning system and the permits that go with it. Class B covers residential and medium commercial work up to 30 ton air conditioning, boilers to 2,000 MBH input and furnaces to 500 MBH. Class C covers one and two family homes with air conditioning to 5 tons, furnaces to 200 MBH input and boilers to 399 MBH. Earning one takes documented hours, five years of them for Class C and ten for Class A, a personal qualification review in front of the board, and a written examination passed at 70 percent, so asking which class somebody holds is a fair question rather than a rude one. Code Enforcement also publishes a List of HVAC Contractors grouped by license heading. The copy on the city site is dated 2022, so a name missing from it is a reason to telephone the licensing department on (315) 448-8773 and not a conclusion. Two more things are city specific. The HVAC permit is a separate trade permit, pulled apart from any residential construction permit, through the Central Permit Office at One Park Place, 300 South State Street. And the Property Conservation Code requires heating equipment to hold 68F from September 15 to May 31, measured two feet from an exterior wall, with that capability judged against an outside temperature of minus ten degrees Fahrenheit. A furnace that keeps up in November and loses the house in January is not having a bad week, it is failing the standard the city itself uses.
