Editorial Standards: How HVAC Gist Decides What to Publish

This page documents the rules HVAC Gist editorial work follows. It is separate from our methodology page (which covers how facts are verified) and our about page (which covers what the site is and who runs it).

Fact-Source Rule

Every factual claim published on HVAC Gist must trace to a verified source in the research source files. This includes:

• Model numbers, SEER2/HSPF2/AFUE ratings, sound dBA, refrigerant types
• Equipment and installed pricing ranges
• Warranty terms, registration windows, exclusions
• Recall histories and class-action investigations
• Federal tax credit status and dollar amounts
• State HEAR/HEEHRA program availability and income tier thresholds
• Manufacturer corporate history, parent ownership, acquisitions

If a claim is not in the research source, the claim does not appear in the article. AI-assisted drafting tools used in production are constrained to facts present in the source documentation — they cannot introduce new claims, even plausible-sounding ones.

Excluded Content

HVAC Gist explicitly does not publish certain content categories.

Excluded: Commonly Repeated False Claims

The following claims appear frequently in HVAC content online but fail fact-source verification against primary documentation. HVAC Gist does not repeat them:

• “Federal 25C tax credit available for 2026 installations” — credit terminated December 31, 2025 under OBBBA (Public Law 119-21)
• “R-454B is a drop-in replacement for R-410A” — refrigerants are not interchangeable; outdoor unit and indoor coil must match
• “SEER and SEER2 are the same metric” — SEER2 is the 2023 federal test methodology, ~5% lower than legacy SEER
• “Up to $8,000 HEAR rebate” without AMI tier qualifier and state availability gate
• “Manual J load calculation is optional” — federal energy code requires it for new installations
• “Yellow furnace flame guarantees carbon monoxide” — yellow can be benign (humidifier interference)
• “DIY refrigerant handling is fine for small leaks” — EPA Section 608 certification is federally required
• “Annual maintenance is optional” — EPA recommends annually and most manufacturer warranties require documented annual service

A full per-page list of excluded false claims lives in our internal content plan and is checked before every publication.

Excluded: Speculation Beyond Source

We do not extrapolate beyond what the source documents. If a manufacturer spec sheet lists SEER2 ratings for 2-ton, 3-ton, 4-ton, and 5-ton variants but not 2.5-ton or 3.5-ton, we publish the documented sizes and note the gap rather than guessing the intermediate values. If a recall affected specific date-of-manufacture ranges, we cite the documented ranges rather than expanding the affected window.

Excluded: Personalized Recommendations

HVAC Gist does not provide individual purchase recommendations through editorial channels. Specific brand, model, tonnage, and contractor selection requires knowledge of the reader’s home (square footage, climate zone, ductwork condition, electrical infrastructure, regional rebate availability, dealer network density in their ZIP code) that editorial cannot evaluate from public documentation. For personalized recommendations, contact a licensed HVAC contractor in your area through the manufacturer’s official dealer locator.

Excluded: DIY Repair Tutorials

We do not publish DIY refrigerant repair, gas line work, electrical service, or other tutorials that risk personal injury when performed without training. EPA Section 608 certification is federally required for any refrigerant handling. Gas line work is regulated by state plumbing and mechanical codes. We do publish DIY-appropriate maintenance content (filter replacement, visual inspection, thermostat calibration) with explicit boundaries on when professional service is required.

Conflict of Interest Policy

HVAC Gist editorial does not accept payment, free equipment, sponsored travel, or any commercial consideration from HVAC manufacturers, dealers, contractors, lead-generation networks, affiliate programs, or industry trade groups in exchange for editorial coverage, ranking, or favorable mention. We do not currently operate affiliate marketing programs on the site.

If a commercial relationship is introduced in Phase 2, it will be disclosed on every affected page with FTC-compliant language, marked visually, and excluded from any buying-guide ranking determinations. Sponsored content, if introduced, will be labeled as sponsored and separated from editorial content.

Editorial owners do not hold financial positions (stock, options, partnership interest) in residential HVAC manufacturers, distributors, or installation contractor businesses covered by the site.

Language and Style Standards

Verdict-First Structure

Every brand review, comparison, and pillar page leads with a “Quick Verdict” or “TL;DR” answering the article’s core question in 40–60 words. Company history, corporate background, and brand heritage are demoted to the last position on the page — not because they are unimportant but because buyers in active decision mode need decision-relevant content first.

Categorical H2 Headlines

H2 headings name the topic of the section, not the finding (e.g., “Pricing by Tonnage” rather than “Carrier Costs $4,500 to $11,500 Installed”). This format is optimized for AI Overview citation in 2026 search results.

Source Transparency

When a citation appears in the article body — to AHRI, EPA, IRS, DOE, ENERGY STAR, a manufacturer spec sheet, or a contractor aggregator — we name the source organization directly rather than using generic language like “studies show” or “experts recommend.”

Number Specificity

We publish specific numbers (96.5%, $4,500–$7,300, 21.0 SEER2) rather than rounded estimates (“about 97 percent,” “around five grand,” “more than 20 SEER2”) when the source supports the specificity. When a range is appropriate (regional pricing variance, ownership-period payback windows), we publish the range with the source.

Active-Voice Default

Passive voice is acceptable where the actor is unknown or irrelevant. Default style is active voice (“Carrier registered the warranty within 90 days”) rather than passive (“The warranty was registered within 90 days by Carrier”).

Third-Person Address

We write in third person about products and brands and address the reader directly with “you” and “your” rather than first person (“I” or “we”) when giving guidance. This is a consequence of multiple contributors and AI-assisted drafting — first-person construction would be misleading about which individual is speaking.

YMYL Disclosure Standards

For content with direct financial or safety consequences:

• Tax credits and rebates must include current status (active/terminated), program identifier, and source agency
• Refrigerant safety must reference EPA Section 608 certification requirements
• Combustion safety must reference CDC carbon monoxide guidance and EPA professional inspection recommendation
• Class-action investigations must be disclosed with the firm name and investigation date, treating allegations as allegations until adjudicated
• Recalls must reference CPSC recall number, date-of-manufacture window, and remedy

Source Currency Standards

A source is considered current if it reflects the regulatory or product state as of the article’s “Last reviewed” date. We re-verify primary sources when:

• A new federal regulation takes effect (AIM Act phasedown thresholds, federal tax credit changes)
• A manufacturer announces a model lineup refresh
• A recall is issued affecting a covered product
• A class-action investigation status changes (filed, certified, settled)
• A state HEAR program launches, exhausts, or changes eligibility

When re-verification reveals outdated content, we update the article and log the update at /corrections/ with the date.

Editorial Review Workflow

Phase 1 editorial review is a single-pass check by the editorial owner against the research source files before publication. Phase 2 will introduce a second-pass technical review by a credentialed HVAC reviewer; that review path will be disclosed on each affected article when implemented.

We do not currently meet the higher bar of two-stage editorial review with named credentialed technical reviewer that some HVAC content sites operate under. We are transparent about this gap rather than overstating our editorial process.

When Standards Conflict

When standards conflict — for instance, when an AIO-optimized 40–60-word answer cannot fully convey a YMYL safety nuance — accuracy and safety win over format. We publish the longer, more careful version and accept reduced AIO citation likelihood for that section.

Reach Editorial

Standards-related questions, fact-source verification requests, and reports of editorial standards violations should be submitted through the contact path on the /corrections/ page.
