GrindSupply builds and runs the four systems HVAC contractors leak the most money on: missed-call text-back so an unanswered ring turns into a booked conversation, appointment reminders that cut no-shows without a human on the phone, dispatch routing that gets the right tech on the right job without a clipboard, and review automation that lifts your Google ranking on autopilot after every completed job.
An AI voice agent that picks up every inbound call to your main line — day, night, weekends, holidays. It greets the caller by name when the CRM has it, asks the three or four questions your office team actually uses to qualify a job (system type, urgency, address, callback preference), and either books the call onto your dispatcher's calendar in real time or hands a clean transcript to whoever is on call. The voice is conversational, not robotic; callers don't realise they're talking to a system until it offers to transfer them. See the full system detail on the Services page.
When a homeowner fills out a web form at 11:40pm — between the kids' bedtime and a Saturday AC failure — they do not want to wait until your office opens. The after-hours flow answers the form, qualifies the job, and offers a real available slot from your dispatch calendar before the lead goes cold. If the slot is rejected it offers the next one; if the lead goes quiet, a text-back sequence kicks in within 90 seconds so the conversation stays alive. See the full system detail on the Services page.
Every lead and every estimate lands in a structured pipeline with stages your team actually uses: new, qualified, estimate sent, won, lost. Estimate follow-ups go out on an automated cadence — day 2, day 5, day 10 — with the right nudge based on what the customer has or has not opened. Old customers who have not booked in 12+ months get a seasonal reactivation nudge. Nothing is sent that a human does not approve during the first month; after that, the cadence is tuned and your team only intervenes on edge cases. See the full system detail on the Services page.
After a job is marked complete in ServiceTitan or Housecall Pro, the customer gets a text the next morning with a one-tap review link to Google — timed for the moment they are most willing to share. Customers who indicate an issue — either by replying to the text or by leaving a 1–3 star review — get routed to a private channel so you hear about it before it hits your public profile. Happy customers get the public ask; unhappy customers get the recovery flow. Steady, compounding lift to your local-map ranking. See the full system detail on the Services page.
All four verticals run on the same engagement: a $2,500 setup that ships in two to three weeks, plus a $750/month retainer that keeps conversation flows tuned, sequences fresh, and integration tweaks turned around in 24 business hours. There is no per-vertical upcharge. If you only need one of the four, we scope to that — but most contractors recover more by stacking two or three because the missed-call text-back and the dispatch routing compound on each other.
Not a fit if you're pre-revenue, only doing new construction, or just shopping for a DIY chatbot widget.
We'll look at your current lead flow, give you an honest assessment of where leads are slipping, and quote a setup cost up front. No commitment required from the call.
