Comb the outside AC unit's bent coil fins straight, the public library serving Marfa.

Some of the coil fins on this library's outdoor unit are bent flat over each other from years of storms, mowing debris, or a stray pressure wash, closing the same millimetre gaps this washing rung just cleared and keeping the coil from shedding heat.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

before/after fin-straightness photos + tool confirmation + GPS

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. Power off the outdoor unit at its own outdoor disconnect switch before anything touches the cabinet, the base, or the coil, and confirm the disconnect is off before starting.
2. Identify the sections of bent or matted-flat fins by sight, usually along the lower third of the coil or wherever debris has struck it.
3. Confirm with library staff how prior fin damage has been handled, then select the fin comb tooth spacing that matches this unit's fin spacing, and draw the comb through the bent section in the direction the fins run, a few passes at a time, never forcing it.
4. Work across the full bent section until the fins stand parallel and open again, then photograph the coil before and after.

What counts as done

• Confirmation of library staff permission and coordination on site
• Confirmation that the outdoor disconnect was switched off before the coil was touched
• Before photo of the bent, flattened fin section
• After photo of the fins standing straight and open
• Confirmation that only a fin comb sized to this unit was used, never an improvised tool

Proof is measured against these, not judged by taste.

The standard this serves

Energy Efficiency Audit. Energy efficiency work begins with the walkthrough audit, the kind the ASHRAE standard describes: a trained eye moving through a building, reading the bills, the walls, the lights, and the equipment, and coming out with the short list of fixes worth doing first. Mastery looks like an auditor who can feel where a building is bleeding money within the hour, and prove it on paper. That instinct is trained by repetition on real buildings. This packet is one repetition: one system observed, one reading taken, one finding recorded the way the standard asks.
