Illustrative day. Lead Dog fits calls against real tech availability and location.
Emergency calls drop into the day around the work already booked, so nobody sits waiting and nobody works until nine at night.
Software built for HVAC contractors.
Two seasons of chaos and ten months of maintenance agreements. Lead Dog handles both — answering the calls you can't get to, dispatching by availability, and keeping plan visits on the calendar all year.

Run your entire HVAC business from one app
Scheduling, estimates, invoicing, tech management, messaging and reporting — working together, not bolted on.
Lead Management
Every call answered and captured, even at seven in the evening when the AC quits and nobody is in the office.
Project Management
Dispatch techs, run multi-day installs and watch job status update from the field on one board.
Estimates & Invoicing
Send good-better-best options on the spot, invoice on completion and take payment before you leave.
Route Optimization
Sequence service calls geographically so techs spend the day fixing systems instead of driving between them.
Messaging
Keep tech questions, model numbers and photos attached to the job rather than in someone's texts.
Reports
See revenue by job type, tech and service plan — and whether your maintenance agreements actually pay.
