Merrimack County HVAC Permit Requirements
In Merrimack County, New Hampshire, HVAC permit requirements are primarily handled at the local municipal level. While there isn't a specific county-level "Building & Safety Division" that issues HVAC permits for all of Merrimack County, individual towns and cities within the county manage their own permitting processes. This means that the exact rules, application procedures, and fees can vary depending on the specific municipality where the property is located. Generally, permits are required for HVAC installations and major repairs. Some municipalities may also require separate permits for gas line work.
New Hampshire requires HVAC contractors to hold a state license through the Board of Home Improvement Contractors. This license involves passing a trade exam, providing proof of experience, and maintaining insurance. Additionally, work involving refrigerants requires EPA certification.
Unincorporated Areas
New Hampshire has very few unincorporated areas, with most of them being located within the White Mountain National Forest. For properties in these rare unincorporated areas, the permitting process can be less defined and may differ from those within established towns or cities. However, given the scarcity of such areas, most properties in Merrimack County will fall under the jurisdiction of a specific town or city's building department.

State-Level Building Codes for HVAC in New Hampshire
The State of New Hampshire maintains a statewide building code, which includes specific standards for mechanical and energy systems. As of the most recent updates, the state has adopted the 2021 editions of the International Code Council (ICC) model codes, with the exception of the energy code, which remains at the 2018 edition. These codes are adopted by reference under New Hampshire Revised Statutes Annotated (RSA) Chapter 155-A.
The primary codes governing HVAC installations in New Hampshire include:
- International Mechanical Code (IMC) 2021: Governs the design, installation, and maintenance of mechanical systems, including heating, ventilation, and air conditioning.
- International Residential Code (IRC) 2021: Provides requirements for mechanical systems in one- and two-family dwellings and townhouses.
- International Energy Conservation Code (IECC) 2018: Sets the energy efficiency standards for building envelopes and mechanical systems, including HVAC equipment.
These codes are applied with specific New Hampshire amendments, which are reviewed and recommended by the state board and ratified by the legislature. It is important to note that local municipalities may have additional requirements or stricter standards, and some jurisdictions may not have local building code enforcement, in which case the State Fire Marshal's Office may have jurisdiction.
Primary State Board and Agencies
The administration and oversight of the state building code are managed by the following entities:
- State Building Code Review Board (BCRB): This board is responsible for reviewing model codes, recommending legislation to adopt or amend these codes, and hearing appeals related to the application and enforcement of the state building code.
- New Hampshire Division of Fire Safety: Works in conjunction with the building code process, as the state building code and state fire code are closely linked in New Hampshire.
- Office of Professional Licensure and Certification (OPLC): Through the Board of Mechanical Safety and Licensing, this office oversees the licensing of fuel gas fitters and mechanical businesses, which is a critical component for professionals working on gas-fired HVAC systems in the state.
