Winston County HVAC Permit Requirements
In Winston County, Alabama, HVAC permit requirements are handled at the county level for properties in unincorporated areas. If your property is located within an incorporated city in Winston County, that city's building department will be responsible for issuing permits, not the county.
Alabama state law mandates that HVAC work must be performed by licensed contractors. To perform HVAC work legally in Alabama, a license from the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors is required. This includes installing, servicing, or repairing heating and air conditioning systems.
Permitting processes, including inspection procedures and fee structures, can vary by jurisdiction within Alabama, as permitting is administered at both the county and municipal levels.
For properties in unincorporated areas of Winston County, the Winston County Commission is the relevant authority for building permits. While the county commission's offices are located in Double Springs, a specific county building permit office address was not published.
Generally, permits are required for:
- Complete system replacements
- New HVAC system installations
- Major component replacements (e.g., new condensing units, furnaces, or heat pumps)
- Ductwork modifications (adding new ducts or substantially altering existing systems)
- Electrical connections for HVAC equipment
It is recommended to confirm current permit requirements directly with the relevant city or county department before beginning any project, as rules and fees can change.

Overview of HVAC Building Codes in Alabama
Alabama does not have a single, mandatory statewide building code for all residential construction. Instead, the state operates under a decentralized system where building regulation is primarily handled at the local level. Cities and counties have the authority to choose whether to adopt and enforce specific building codes. Consequently, code requirements and the specific editions of codes enforced can vary significantly across different jurisdictions within the state.
Adopted Codes and Standards
While local adoption varies, many jurisdictions in Alabama utilize the International Codes (I-Codes) published by the International Code Council (ICC) as their baseline. For state-regulated buildings (such as state-funded projects), the Alabama Division of Construction Management (DCM) has adopted the 2021 editions of the International Building Code (IBC), International Mechanical Code (IMC), and other related standards. Additionally, the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR) mandates that all certified contractors adhere to specific minimum standards for installation, service, and repair, which include the International Mechanical Code, International Residential Code (IRC), International Fuel Gas Code, and the National Electrical Code (NFPA 70), among others.
Primary State Agencies and Boards
- Alabama Building Commission (ABC) / Division of Construction Management (DCM): Responsible for adopting and amending building codes for state-funded buildings and providing guidance for local jurisdictions.
- Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR): Governs the licensing of HVAC contractors and establishes the minimum technical standards for HVAC installations, service, and repair across the state.
- Alabama Energy and Residential Codes Board: Provides guidance and adopts statewide minimum standards for energy efficiency and residential construction, though enforcement remains a local responsibility.
