AL HVAC: Suggested Study Strategy

1Learn the Board numbers exactly: a $20,000 Form BF-1 bond, $220 active and $110 inactive annual fees, a December 31 expiration, a $250 late fee, and administrative fines up to $2,000 per violation
2Answer mechanical and fuel gas questions out of the 2021 IRC Chapter 24 and Part V, since the International Mechanical Code is not on the HAC reference list
3Master EPA Section 608 evacuation levels from 40 CFR 82.156 Table 1 and the AIM Act leak-repair rule that took effect January 1, 2026 at a 15-pound full charge
4Practice ACCA Manual J load calculations for Alabama design conditions - Birmingham near 94 F dry bulb and Mobile near 93 F dry bulb with a 78 F coincident wet bulb
5Work the NASCLA business blocks separately; estimating, labor laws, payroll taxes, and financial management are each scored on their own and total 31 of the 115 items
6Know Alabama lien deadlines: six months to file in probate for an original contractor, four months for others, thirty days for day laborers, and six months to sue after the debt matures
