How to Start an HVAC Business in Alabama (2026)

Last updated: February 25, 2026

Alabama is one of the states that requires a state HVAC contractor license, regulated by the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors (HACR Board). You need qualifying experience (2 years registered apprenticeship, approved technical program, or 3,000+ hours supervised work), must pass a written exam, post a $20,000 performance bond, and pay $220/year for your license. On top of the state license, you need EPA Section 608 certification for handling refrigerants. Alabama’s hot, humid climate creates strong year-round demand for HVAC services, making it a solid market for contractors. This guide covers every requirement using official Alabama sources.

How to Start an HVAC Business in Alabama (Step by Step)

Step 1: Meet Experience Requirements

Before you can take the HACR Board exam, you must meet one of the following experience/education requirements:

2 years of registered apprenticeship under a licensed Alabama HVAC contractor
Approved Alabama community college or technical school HVAC program (typically 1-2 year programs)
3,000+ hours of supervised experience working under a licensed HVAC contractor
Equivalent combination of education and practical experience

You must be able to document your experience. The HACR Board verifies all experience claims during the application process.

Step 2: Pass the HACR Board Exam

The HACR Board administers a written exam for HVAC contractor licensing:

Refrigeration	60	3 hours	70%

Exam fee: $175
Topics covered: Installation, maintenance, repair, load calculations, ductwork, electrical, controls, codes, and Alabama regulations
Study resources: The HACR Board provides a study guide and reference list on their website

Step 3: Get Your Performance Bond

Alabama requires a $20,000 performance bond before your HVAC license is issued. The bond protects consumers against faulty workmanship and financial harm.

Bond amount: $20,000
Annual premium: Typically $200-$600/year (1-3% of bond amount, based on credit score and financial history)
Where to get it: Any surety bonding company licensed in Alabama

Step 4: Apply for Your State License

Submit your license application to the HACR Board with:

Completed application form
Proof of passing exam score
$20,000 performance bond
$220 annual license fee
Documentation of experience/education

License renewal is annual at $190/year. The HACR Board may require continuing education for renewal.

Step 5: Get EPA Section 608 Certification

Federal law requires EPA Section 608 certification for anyone who handles refrigerants. This is mandatory for all HVAC technicians regardless of state licensing.

Certification Type	Covers
Type I (Small Appliances)	Systems with less than 5 lbs of refrigerant
Type II (High-Pressure)	High-pressure refrigerants (most residential/commercial AC)
Type III (Low-Pressure)	Low-pressure refrigerants (large chillers)
Universal (Recommended)	All types – covers everything

Cost: $150-$250 for exam and certification
Where: EPA-approved testing organizations (ESCO Institute, HVAC Excellence, etc.)
Duration: Certification does not expire (one-time exam)

Step 6: Form Your Business and Get Insurance

Register an LLC with the Alabama Secretary of State ($228 online). Get a municipal business license from your city or county. Apply for a free federal EIN at IRS.gov.

Insurance requirements:

General liability: $1 million per occurrence / $2 million aggregate ($2,500-$5,000/year). Many commercial clients and general contractors require this.
Commercial auto: Required for service vehicles ($2,000-$4,000/year).
Workers’ comp: Required at 5+ employees. HVAC work carries higher workers’ comp rates due to physical labor, heights, and electrical hazards.
Tools/equipment coverage: Inland marine insurance for tools and equipment transported in vehicles ($300-$800/year).
