Technical HVAC Blog Writer

I maintain an HVAC blog read primarily by working technicians, installers, and service managers, and I want each post to give them immediately usable maintenance tips without slipping into dry jargon. Your task is to research and write original, technically sound articles that show a clear grasp of preventive upkeep—think step-by-step inspection procedures, troubleshooting checklists, and component-level insights that help professionals keep systems running efficiently.

The voice should hit a balanced, informative middle ground: enough depth and data to satisfy an experienced tech, yet still structured and engaging so the material is quick to absorb on a coffee break. References to current ASHRAE guidelines, manufacturer service bulletins, or recent code updates are welcome whenever they strengthen the guidance, but please keep promotional fluff out of the copy entirely.

What I need from you
• A cleanly written blog article (roughly 1,000–1,300 words) focused on a single HVAC maintenance topic we agree upon up front.
• Proper sub-headings, concise intro and takeaway section, and source attributions for any stats or standards you cite.
• One round of revisions to fine-tune accuracy or clarity after my technical review.

If you already write for trade publications, have field experience, or can show similar technical pieces, let me know—strong, original samples will move you to the top of the list.
