EDITORIAL TEAM —
AFTER HOURS HVACR.
Who writes our content
Our editorial team works alongside licensed Birmingham HVAC technicians to ensure every page on this site reflects current Alabama code, current best practices, and the climate realities of central Alabama. The people writing about heat pumps, capacitor failures, and short-cycling compressors are people standing on a Hoover roof in August pulling pressure readings on a unit that does not want to come back online.
We do not publish what a content mill scraped off another HVAC site. Pages start from field notes — the failures we actually see across Birmingham, Hoover, Vestavia Hills, Homewood, Mountain Brook, Trussville, Pelham, and Alabaster; the equipment we actually pull; the diagnoses we actually charge for. The editorial team then checks every claim against ACCA Manual J, current U.S. Department of Energy guidance, the U.S. EPA Section 608 rule, and the Alabama Board of Heating, Air Conditioning, and Refrigeration Contractors' current code.
That is the standard. Real Birmingham HVAC work, written down honestly, checked against the authorities that actually matter in this trade.
Our editorial standards
- Citation policy. Every code reference, climate stat, and equipment standard cites a primary source — ACCA, ASHRAE, U.S. DOE, U.S. EPA, NIST, or the Alabama HACR Board.
- Correction policy. If we publish something wrong, we correct it on the page and stamp the page with the correction date. Email editorial@afterhourshvacr.com.
- No pricing claims. We do not publish flat-rate prices online. Every job gets a written estimate from a licensed tech on site after the diagnosis.
- No guarantees. We do not promise “same-day,” “free service call,” or response-time windows in writing.
- AI disclosure. Some pages are AI-assisted in drafting. A licensed Alabama HVAC technician reviews every page for accuracy, code, and tone before publishing.
How we research
- 1. Manufacturer service manuals — Carrier, Trane, Lennox, Goodman, Rheem, Mitsubishi, Daikin, Bryant. Wire diagrams, capacities, charge tables.
- 2. ACCA standards — Manual J load calc, Manual D duct design, Manual S equipment selection, Manual T airflow.
- 3. U.S. Department of Energy — efficiency ratings (SEER2, HSPF2, AFUE), southeast climate-zone heating and cooling guidance.
- 4. U.S. EPA — Section 608 refrigerant rule, ENERGY STAR program criteria.
- 5. NIST + NOAA climate data — Birmingham AL design temperatures and humidity ranges, heating and cooling degree days.
- 6. Alabama HACR Board — current contractor licensing rules and code references.
- 7. ASHRAE — duct design and indoor environment standards (62.2, 90.2, refrigerant position docs).
When a topic is contested in the trade, we name the disagreement and present the contested view from each authority — instead of pretending there is one settled answer.
