Industries

Same three loss channels. Different call mix.

The estimator and the DialWorth Score do not change by trade — capacity, conversion and turnover loss are computed the same way whether you run HVAC or junk removal. What changes by trade is the shape of the calls arriving: how much of the volume is same-day emergency, how wide the job value spread is, and how much a missed call actually costs to replace.

Built out trade by trade, not all at once

Five pages are live so far — the largest trades in our own outreach. The rest are coming as each one earns a page worth reading rather than a template with the trade name swapped in. Until yours is up, the estimator and the diagnostic do not need a dedicated page to work for you: select your trade on the estimator either way.

HVAC

Phone performance for HVAC operators

No-heat and no-cool calls arrive same-day and disproportionately during two narrow seasonal windows — exactly when capacity loss is most expensive.

Plumbing

Phone performance for plumbing operators

Emergency and planned work move through the same queue with very different stakes, and the same booking rate can mean two different things depending on which one you are looking at.

Electrical

Phone performance for electrical operators

A safety call, a code call and a planned install move through one queue, and licensing constraints add a dispatch risk other trades don't carry.

Roofing

Phone performance for roofing operators

A queue that is empty until a storm fills it in one afternoon, and two conversion tracks — insurance-claim and out-of-pocket — that behave nothing alike.

Restoration

Phone performance for restoration operators

Near-total emergency volume, response speed as the conversion mechanism itself, and on-call staffing that never gets a slow season.

What actually differs by trade

Three things move a phone operation's numbers by trade, and none of them are a performance question — they are a structural one, which is why they belong on an industry page rather than folded into a single generic one.

Emergency share. A no-heat call in January and a routine filter swap are not the same call. Trades with a large same-day-emergency share (HVAC, plumbing, restoration) see capacity loss concentrate into short, predictable windows; trades that run mostly scheduled work (landscaping, painting) see it spread evenly and are more forgiving of a slow answer.

Job value spread. A trade quoting $150 diagnostics next to $12,000 replacements has a wider consideration curve on the high end, which lowers first-call conversion for reasons that have nothing to do with how the call was handled — see the call-mix section of the benchmarks page for why that is not a performance gap.

Seasonality. Some trades run flat all year; others swing hard enough that the same staffing level is right-sized in April and badly understaffed in July. A benchmark or a booking rate read in the wrong month tells you about the season, not the team.

What does not change. The definitions, the score, and the estimator's formula are the same across every trade. Comparing your score to your own trade's population — not to the general population — is the only adjustment the model needs, and it is already built in.
