Airflow before and after, the lint you pulled out photographed, and a record the property manager will accept without a phone call. $59, once.
Not a generic service form with a notes box at the bottom. The fields are the ones that matter on this job, and the document at the end is the one your customer expects.
Take your airflow reading and note the run length, material and how many bends. It's the number that proves the job did something.
Log each section and the method. Photograph the debris — this is the trade where the photo is the sales tool for next year.
Same reading, same spot. The two numbers side by side on the report is the whole product.
Crushed run, disconnected joint, bird nest, transition that shouldn't be there. Recorded as findings with photos, not a verbal mention that gets forgotten.
Run length, material and bends · airflow before and after with units · sections cleaned and method · debris photos · findings with severity · transition and termination condition · recommended interval · technician · customer signature.
It doesn't say a vent meets any standard and doesn't calculate anything for you. You enter the readings, it keeps them together and prints them.
Do the whole job offline — photos and all — and it syncs itself when you're back in range.
There's a button inside every work layer that sends me a message. I read all of them myself. When a fix ships because someone told me, it goes in the changelog with a thank-you.
