HVAC Not Heating aims to publish troubleshooting information that is understandable, transparent, and safe to use.
Who writes the guides
The site is founded and edited by Jabeer, a homeowner who documents personal home-maintenance and troubleshooting experiences and organizes information from manufacturer documentation, government sources, and established reference material. Jabeer is not a licensed HVAC technician, and the site does not represent its articles as professional service reports.
Sources and research
Whenever practical, research begins with the manufacturer’s owner manual, installation information, technical documentation, parts information, or official error-code guidance. Government and safety sources may also be used for certification, refrigerant, combustion, electrical, and maintenance topics.
Brand and model details are checked before a guide describes a model-specific code, part, reset sequence, or test. When exact model information is unavailable, an article should explain that procedures vary and direct readers to documentation for their equipment.
Personal experience
Articles may include lessons from checks or maintenance Jabeer has performed at home. A guide will not claim first-hand testing, ownership, or a successful repair when that did not occur.
AI assistance and illustrations
AI tools may assist with outlining, editing, or producing explanatory illustrations. Technical claims are reviewed against source material before publication. AI-generated illustrations are identified as illustrations and are not photographs of a specific system, repair, or service visit.
Safety standards
Guides distinguish basic homeowner checks from work that should be handled by a qualified professional. Extra caution applies to gas connections, combustion equipment, live electrical testing, refrigerant circuits, sealed systems, and any repair that could create a fire, shock, carbon-monoxide, or refrigerant hazard.
No article replaces the manufacturer’s instructions, local code requirements, or professional judgment.
Affiliate independence
Some links may generate a commission. Payment does not determine the order of diagnostic steps or whether a recommendation is described as safe. Paid relationships are disclosed near relevant links and on the Affiliate Disclosure page.
Corrections and updates
Articles may be revised when better source material becomes available, a manufacturer changes documentation, or a reader identifies a reproducible error. To suggest a correction, please use the Contact page with the article URL, equipment model, and supporting information.
