Editorial policy
The scope has to be clear before the verdict is useful.
These standards apply to buying guides, cost pages, brand comparisons, quote reviews, and safety coverage.
Source hierarchy
Technical and regulatory claims start with DOE, ENERGY STAR, EPA, AHRI, ACCA, code authorities, licensing boards, and manufacturer documents. We use secondary reporting for market context and buyer experiences, not to override primary requirements.
Cost claims
Every price range is a dated planning range with its scope stated. We do not present an equipment-only price as an installed total. Local labor, access, ducts, electrical work, permits, matched indoor equipment, controls, and refrigerant work can move the number materially.
Brand comparisons
We compare exact product families and local support, not reputations alone. A brand verdict addresses model tier, certified match, controls, parts availability, warranty terms, dealer quality, and buyer fit. Commission rates and sponsorship do not change order or verdict.
Safety and professional boundaries
We explain electrical, refrigerant, condensate, airflow, and combustion-adjacent issues so a homeowner can budget and question a quote. We do not coach unlicensed refrigerant handling, high-voltage work, or code evasion.
Updates and corrections
Refrigerant rules, efficiency requirements, incentives, product lines, warranty terms, and prices carry dates and receive priority updates. Report a factual issue to david@aircondition.guide. We correct the page and update its modification date rather than leaving stale guidance in place.
AI-assisted work
Automation may help organize sources, check consistency, or draft structure. Publication still requires source review, buyer-fit judgment, and the same correction standard. Unsupported specificity does not become a fact because a model produced it.
