Editorial Standards
Citation policy
Every technical claim — load calc rules, refrigerant rules, efficiency ratings, code references, climate data — is sourced from a primary authority. The order of authority is:
- Manufacturer service manuals.
- ACCA Manual J / D / S / T standards.
- U.S. Department of Energy guidance.
- U.S. Environmental Protection Agency (Section 608, ENERGY STAR).
- NIST and NOAA climate data for Birmingham AL.
- Alabama Board of Heating, Air Conditioning, and Refrigeration Contractors.
- ASHRAE position documents and standards.
We do not cite blog posts, content farms, or HVAC sites that exist only to rank.
AI disclosure
Some pages on this site are AI-assisted during drafting. Every page is reviewed by a human editor and checked by a licensed Alabama HVAC technician for accuracy, code, and tone before it is published. AI never publishes directly to this site.
Where a page is AI-assisted, we treat it the way a newsroom treats a wire copy edit — the byline still belongs to the editorial team and the standards still apply.
Correction policy
If we publish something wrong, we correct it on the page and stamp the page with the date of correction. We do not silently rewrite history. Substantive corrections — anything that changes the meaning of the page — are noted in a correction line.
To request a correction, email editorial@lockwellhvac.com with the page URL and the issue.
What we will not publish
- Flat-rate prices, dollar quotes, or “starting at” figures online.
- “Free service call” or “free estimate” promises in writing.
- Response-time guarantees (“30 minutes,” “same day”).
- Fabricated technician credentials, named bios, or staged photos representing a person who is not on staff.
- Fake reviews or staged testimonials.
- Medical claims about HVAC equipment. HVAC is not a medical device. We do not publish health advice.
- “Family-owned since [year]” or any since-year claim that is not verifiable.
- Other contractors' brand names presented as our own.
Service across language and community
Lockwell HVAC publishes content in English and Spanish (Lockwell HVAC en español) so the people we dispatch to in Birmingham can read what they signed for. Both versions of every page go through the same editorial review and the same code check.
