Hiring a company, not a person?
New Hampshire licenses fuel gas fitters and plumbers through the Mechanical Licensing Board; no state license for air conditioning or refrigeration work was found on the Board's pages.
Doing it yourself
Fuel gas fitting work inside an existing single-family stand-alone structure owned and occupied by the person doing the work as their primary residence is exempt from licensing (RSA 153:36, I).
