About HVAC Gist: Independent Research for Homeowners

We are not a contractor, manufacturer, dealer, lead-generation aggregator, or affiliate partner. We do not sell equipment, install equipment, or accept payment for product placement. We also do not currently operate a physical test lab — every product specification we publish is verified against primary manufacturer documentation, AHRI Directory listings, and federal regulatory filings, not in-house testing.

Why This Site Exists

Most residential HVAC content online falls into three categories: manufacturer-sponsored marketing, dealer-network lead-generation pages, or aggregator sites that copy specifications without verifying them against current model years. Homeowners making a 10–20-year equipment decision deserve clearly-sourced, current-year information about what brands actually sell, what warranties actually cover, and which federal and state incentives are actually available in 2026.

The federal Section 25C tax credit, for example, terminated December 31, 2025 under the One Big Beautiful Bill Act. As of May 2026, aggregator sites continue to promote 25C as if it were active for 2026 installations. HVAC Gist flags this kind of stale information directly because $2,000 in expected federal credit that doesn’t exist materially changes a buying decision.

How We Produce Content

Each brand review and pillar page is built from a verified research card that documents every factual claim against a primary source. Primary sources include:

• Manufacturer official websites and spec sheets — for current model lineup, SEER2/HSPF2 ratings, warranty terms
• AHRI Directory (ahridirectory.org) — for residential HVAC equipment certification data
• U.S. Department of Energy Energy Saver — for technology basics, efficiency framing, lifespan
• ENERGY STAR — for certified product criteria and rebate eligibility
• EPA Indoor Air Quality program — for maintenance and combustion safety guidance
• IRS 25C tax credit page + OBBBA legislation — for federal tax credit status
• State HEAR/HEEHRA program pages — for state-by-state rebate availability
• CPSC.gov — for product recalls
• Consumer Reports public summaries — for reliability rankings
• PICKHVAC, Modernize, HomeAdvisor, Forbes Home — for contractor-quote pricing aggregation
• HVAC-Talk forums, /r/HVAC — for technician sentiment and field-failure patterns

When a fact is not documented in primary sources, we do not publish it. When sources disagree, we surface the disagreement rather than picking the more flattering number.

AI-Content Disclosure

HVAC Gist content is produced with AI assistance under human research oversight. Every published page is built from a human-curated research card containing verified facts and source URLs. AI tools assist with structuring, drafting, and editing the prose — but no factual claim, model number, price range, warranty term, or regulatory citation appears on the site unless it traces to a verified entry in the research source.

We disclose this because Google’s 2025 Search Quality Rater Guidelines require transparency about AI-assisted content production. We follow that guidance.

What We Don’t Do

We intentionally do not publish:

• Sponsored placement — no manufacturer or dealer pays for inclusion or ranking
• Affiliate links — Phase 1 of the site operates without affiliate revenue
• Original lab testing data — we accept the resulting trust ceiling rather than publish fabricated test results
• Photos or videos taken by us of equipment — we use manufacturer-supplied imagery or none
• Personal anecdotes presented as broad evidence — single-installation experience is not representative
• DIY repair tutorials — most residential HVAC repair work requires EPA Section 608 certification for refrigerant handling and risks personal injury when done without training

Contributors and Oversight

HVAC Gist operates as a small independent project. The site is built and maintained by a single editorial owner who handles research, verification, content production, and corrections. We do not currently employ NATE-certified technicians, professional engineers, or BPI-certified building analysts on staff. We do not claim editorial credentials we do not hold.

When higher-credential review becomes appropriate as the site grows, we will name reviewers individually and link to their public credential verification (NATE Directory, state board lookup, P.E. license database) rather than asserting unverifiable expertise.

Corrections and Feedback

We maintain a public corrections log at /corrections/ documenting any factual errors readers identify and the date of each fix. If you find an error, please email the editorial team — contact details are on the Corrections page. We treat reader-reported corrections as priority work because YMYL content has direct financial consequences for homeowners acting on what we publish.

Independence and Funding

Phase 1 of HVAC Gist operates without affiliate marketing, sponsored content, or paid placement. We do not currently monetize the site through any commercial relationship with manufacturers, dealers, contractors, lead-generation networks, or product affiliate programs. Future monetization decisions will be disclosed transparently before implementation, and any commercial relationships will appear with FTC-compliant disclosure on every affected page.

Reach Editorial

Editorial questions, factual corrections, source verification requests, and suggestions for new content topics can be submitted through the contact path on the Corrections page. We do not provide installation quotes, dealer recommendations, or personalized purchase advice — for that, contact a licensed HVAC contractor in your area through the manufacturer’s official dealer locator.
