A no-cool August attic on Missionary Ridge. A January heat-pump aux-strip out on Lookout Mountain. The agent answers, qualifies the symptom, and writes the same-call slot to the 423-area tech's board before the dispatcher wakes to a full inbox.

Two after-hours pains we already route against — drawn from the same Chattanooga-side playbook that backs the audit replay. The agent qualifies, the tech sees a confirmed slot on the morning board.
The hvac calls we recover
What the audit can defend
Across the 423-area HVAC shops we audit, the morning board sees fewer same-day adds when the after-hours line books the slot on the same call.
Price the recovery inline
Edit any field — the dollar figure below recomputes on the spot. The Holdfast invoice is a flat retainer plus a small per-booked-job bonus; we only invoice against calendar confirmations, never the worked illustration below.
Worked example
The same inputs the corner-of-the-page "recovery card" on each trade page describes — now editable so you can put your own numbers on the line.
Total inbound calls your office takes in a typical week — answered or not.
Default $720 reflects HVAC's install/replacement + refrigerant + emergency-diagnostic mix — above plumbing's $480 mid-band. Edit for your shop.

30 missed calls per week × 4.33 weeks × Holdfast's 55% published recovery rate × $720.00 per booked job. The Holdfast invoice is a flat retainer plus a small per-booked-job bonus; the takeaway on the audit calls only ever invoices against what the calendar confirms.
Most of that leakage sits in the install/replacement mix — heat-pump quotes, refrigerant line repairs, and the Jun–Sept no-cool / January furnace-out peaks where a missed call costs the shop a $620+ ticket rather than a flat-rate service-call close.
Numbers are a worked illustration, not a guarantee. The audit fills the same inputs from your last quarter of calls and tickets.

Next step
A 20-minute audit uses ten of your recent inbound calls and your last quarter's ticket values to fill the same table for your shop — no install, no commitment. The figure above is the upper bound; the audit nails it down.
Numbers are a worked illustration, not a guarantee. The per-shop ROI report ties the same line items to actual booked invoices at the end of every billing week.
Sample projection · HVAC
A worked projection for the same Northstar HVAC shape — see /case-studies for the plumbing counterpart.
Sample projection
A 4-tech HVAC shop running ~165 inbound calls a week with a heavy after-hours mix.
HVAC traffic swings hard by season — January no-heat emergency calls, August weekend AC failures, a slow Wednesday otherwise. The shop already staffs the next-day slate; the missed-call layer just books the urgent slot the dispatcher would otherwise lose to voicemail.
Sample projection — actual outcomes depend on your shop’s call volume.~50 / week
~18 / month
~$16,200 / month
A worked scenario
A no-heat call lands at 6:30am on a January Saturday with a single mom on the line. The agent picks up, confirms gas service is still on and whether the thermostat is throwing a code, and books the first morning emergency slot. The job is a same-day diagnostic call with a ~$900 ticket — repair or replacement booked on the same visit.
Assumptions baked into the headline number
Assumes ~30% would-leave-voicemail miss rate on ~165 weekly calls, ~36% of recovered calls convert to a booked job, and an ~$900 average HVAC ticket. Round numbers are illustrative.
Next step
A 20-minute audit uses ten of your recent 423-area inbound recordings and your last quarter's ticket values to fill the same three rows for your shop — no install, no commitment, no demo deck.
